LOT 55 SAND PINE MICROSITE MEMORANDUM r ~::2-:L ~J ~~ 26 March 1990 TO Timothy P Cannon Interim City Planner FROM James Golden Senior City Planner RE Quantum Park - Lot 55 Sand Pine Microsite I have reviewed the attached correspondence from Michael J Toll and discussed this issue with Tambri Heyden and Kevin Hallahan I have also checked our files on Quantum Park According to Tambri, Carmen was coordinating the microsite areas with Treasure Coast and the developer prior to his departure Tambri recalls that Carmen instructed her to forward any inquiries concerning pine scrub microsite to Kevin, as Kevin had the only copy of the documents that set forth the microsite preservation plan Kevin informed me that he never received any information on the latest microsite preservation plan and that Carmen had been handling these issues prior to his departure. Kevin said that he forwarded Michael Toll's letter to you so that Planning could act as an intermediate between himself and Treasure Coast in attempting to reach a consensus on this issue A review of the Quantum Park files reveals that the latest correspondence we have concerning pine scrub preservation is dated December 1988, and this correspondence does not address the microsite issue. 1 ~l// ~w.<<,- f / "'~'-- ~ (tJAMES[ GOLDEN " /bks cc Tambri Heyden Kevin Hallahan 10t55 Reply To Fort Lauderdale Office QUANTUM CORPORATE PARK Mr Kevin Hallahan Forester/Horticulturalist City of Boynton Beach 200 Seacrest Blvd Boynton Beach, Florida 33435 March 5, 1990 Re Quantum Park, Sand Pine Microsite Area, Lot 55 Dear Kevin I have enclosed for your review and consideration for acceptance, two original surveys of the proposed Sand Pine Microsite Area on lot 55 Once the additional plantings have been completed as requested, I would appreciate written confirmation from you that the area has been accepted by the City, in order that it may be designated as a Sand Pine Microsite If you have any questions, please contact me at your earliest opportunity Thank you for your consideration Very MJT/nb encl cc Mr Glen Francis, Public Distribution Center w/encl Mr George W Zimmerman w/encl Mr Steven W Deutsch w/encl A Deutschf Ireland Properties- Melvin Simon Joint Venture The 110 Tower. 21st Hoor . 110 Southeast Sixth Street.

CONCLUSIONS AND RBCOMMENDA TIONS This tyoperty has been under environmental stress for many years beJuse of its use for livestock production and enhanced hunting and sand mining. Presently, cattle are grazing over the portion of the property north of N. W. 22nd Avenue. The past lowering of the water table has changed and decreased most of the historic wetlands to disjunct fairly insignificant areas that have been or are now used by cattle. Their disruption is further compounded by the invasion of Melaleuca quinquenervia and Schinus terebinthifolius. Regeneration of important upland plant species such as Pinus clausa and Pinus elliottii were seen infrequently over most of the property. Animal life is sparse because of the environmental decline. Frequent boat use of the canals bordering the property is believed to inhibit aquatic invertebrates and fish. It is concluded that the present use of the property will continue the environmental decline and that another projected use such as an environmentally controlled light-industrial park would add little to the present negative environmental situation. If properly buffered, the projected industrial park should have little or no significant impact upon the surrounding region. It is recommended that (1) as many native trees as feasible be saved and used as landscaping material; (2) the degrading wet areas be removed (they are presently mosquito 41 breeding areas during the wet season) and replaced with a series of lakes that will be effective in surface water control; (3) any wetlands that can be feasibly cleansed of exotics be retained; (4) plantings of native vegetation be planted on. and surrounding the sloped banks of the lakes with the concurrence of the environmental staff of the T.C.R.P.C.. (5) the littoral-benthic shoreline of the lakes be planted with native aquatic plants and the lakes stocked with native fish; and (6) the three protected wildlife species be removed to safer on-site locations prior to construction with the concurrence of the environmental staff of the T.C.R.P.C. and the D.N.R. * (7) at least 25% of the existing undisturbed sand pine scrub vegetation (32 acres) at the eastern edge of the property and just north of N. W. 22nd Avenue be preserved by judicious siting of buildings on the various lots in this parcel (see Maps Hand H-l). * NOTE Preservation of this portion of the sand pine scrub vegetation should be the responsibility of the property owner's association and an architectural review committee. 42 , ./ :<. /~ I rr : 'I ECOLOGICAL REPORT FOR QUANTUM CORPORATE PARK BOYNTON BEACH, FLORIDA AMENDMENT #3 DECEMBER 20, 1988 :II- THIS REPORT IS AN AMENDMENT TO THE ORIGINAL ECOLOGICAL REPORT DATED AUGUST 4, 1986, AS AMENDED ON MARCH 16, 1987, AND AS AMENDED ON JANUARY 5, 1988 AMENDHENT #3 DECEHBER 20, 1988 INTRODUCTION I tIs I mportant as we cont I nue the long term deve I opment of Quantum Corporate Park that there be a c I ear understand i ng of the Deve I oper' s intentions and responsIbIlitIes, as well as those that he must interface with at each of the varIous control I ing agencIes The contInued discuss i on of factors impact i ng dec is Ions with respect to Sand Pine Scrub, have clouded a number of the specifIc requirements of the Development Order with recommendations that tend to unjustly expand the orIginal requIrements The Developer has taken the posItIon steadfastly, since theIr acquIsition of the property, that they are dedicated to the preservation of 40 acres of Sand Pine Scrub on the property known as Quantum Corporate Park CPl}il ~~.....~~~h~k diflllil aw~>,.,i.i.,~ s II be lief .~. .Pll~.Jln..t II If 1 '.liirllr _c..,.iWIM."".ilikuirilll!lll.iror A~gJ;J;jit AU ...~JIl1'<lll. .. ..

'c'O ("";' J RESOURCE MANAGEMENT PLAN FOR SAND PINE SCRUB PRESERVE #1 AND #2, QUANTUM PARK, BOYNTON BEACH, FLORIDA 13 December 1988 by Donald Richardson, Ph.D. Ecological Consultants 7301 Summerbridge Drive Tampa, Florida 33614 2 Introduction As per the Development Order proposed by the Treasure Coast Regional Planning Council and the City of BOjnton Beach, approx imately 40 acres of sand pine scrub vegetatiun was set aside as a nature preserve within the Quantum Park (DRI) project Since most of the scrub within the above referenced pruject had been severely dIsturbed by sporadic understory cl~dring and livestock grazing, the said 40 acres was diVIded Into two d i s j un c t san d pin e pre s e r v e s ( Fig u r e 1) Pre s e r v e If lIS 1 0 cat ed north of N.W 22nd Avenue and contains about 25.7 acres of sand pine scrub and abandoned dry prairie/pine flatwoods habitats (Figure 2) Approximately 14 acres of this site is dominated by sand pine scrub vevegation Preserve #2 is located we~l of High Ridge Road and south of N W 22nd Avenue and includes a mixture of 130 acres of sand pine scrub and 1 3 acres of disturbed grassland (Figure 3). The remaining 12 acres of sand pine scrub needed to meet the 40 acre requirement will be selected from extant scrub areas and recreated or reclaimed scrub landscapes (Amendment #3) The purpose of this report is to define the fJroposed management philosophy and methodology for longterm preservation of these two preserve sites BASIC MANAGEMENT PHILOSOPHY The objective of the resource management plan IS to preserve, through management, a representative sample of an original Florida ecosystem, thereby maintaining the natural 3 diversity of both plants and animals. RESOURCE DESCRIPTION PRESERVE #1 Disturbances to plant communities have long oeen vit::wed as an outs ide threat to the normal fun c t ion i n g 0 f the C u nUTlli nIt y In the san d pin e s c rub co mm u nit y, the res i 1 e n c y 0 f m u ::, t 0 f the indicator species has bet?n attributed to recovery 0113 <>prouting fro m pre e xis tin g roo t s t 0 c k s, a s v e r y few s pe c i e sin l he s c rub rel-over via seed (1.e , Ceri:1tiola ericoides and pinus ~.!~~). The vegetation of the preserve area is chara"tt:rIzed as young or early successional sand pine scrub with scattL[ed areas of dry prairie/pine flatwoods A total of 119 plant 5p~cies (41% are obligate to sand pine scrub) have been observed wIthin the preserve (Table 1) Although clearing of the undeL~tory and t h inn i n 9 0 f the san d pIn e 0 c cur red p r i 0 r t 0 1 9 H 3, co mm un i t Y recovery is rapidly occurring The overstory trees are dominated by widely spaced sand pine (pinus clausal (138 trees per acre) of at least two different age classes (113-213 years and 213-35 years) Tree core d3ta from established permanent plots indicates that the averagt:: age of sand pine is 18 34 years old, with the oldest trees (19-30 years) in the northeastern corner of the preserve. There were no trees greater than 38 years, however, hundreds of scattered throughout the preserve. Trees vary 36 7 cm dbh, reaching heights of 37-46 feet. The shrub layer is dominated by widely young sapling are in size from 2 7- spaced scrub oaks 4 (Quercus myrtifolia, Quercus s.eminata), palaf()J:ia feayi, jointweed (Polygonella polygama) and scrub mint l\..-cJnradina grandiflora) Average stem densities were highest for lUILtle oak (93.8 stems per 5 x 5 m quadrat) and sand live oak (79 8 stems per 5 x 5 m qua d rat), w 1'1 i lea v era g e he i g 1'1 t was 2 1 3 .- b H 5 cm One year from the initial sampling effort, stem densities slightly decreased for both species of oaks, but showed some increase for jointweed (polygonella polygama) and Pd13fu~~~ feaYI In the permanent sampling plots Changes in shrub stem densities over time for the Quantum Park scrub communities is consistent with other scrubs In south Florida Recent data collected from 10 year fieid plots at Jonathan Dickinson state Park indicate that scrub species composition remains fairly constant in mature scrub, however, 5 tern den sit i e 5 i n 0 a k s s 1'10 w s a 2 - 3 f old i n c rea see b ,~ n g e SIn shrub densities within the preserve may not change much over the n ex t few yea r s sin c e mo s t 0 f the un d e r s tor y was r ed u c e d tot 1'1 e ground surface in 1983 Seed inputs from existing oaks will require longer intervals before new seedlings can be detected The overall diversity is much higher than compared with other mature scrubs or other areas within Quantum Park (Richardson et al 1986). Except for the oaks, other characteristic shrubs have begun to germinate in the open areas of the preserve These shrubs include rosemary (Ceratiola ericoides) rusty lyonia (Lyonia (Conradina grandiflora), tallowwood ferrug inea), s,-rub mint (X imen ia amer i....aoa), and 5 jointweed (p01ygone11a ciliata and P gracilis) probably the most dramatic change in the shrub layer has been the establ ishment of Ceratiola. Rosemary often does not germinate until 2-5 years postfire, and reach reproductive maturity for 1~ to 15 its seedlin'J~ do not years To date, more than 25 2 year old shrubs have been observed throughout the preserve area Johnson (1986) has shown that staf,J biomass increases slowly from 2 tu 4 years, rapidly from 4 to 10 years and less rapidly between 10 and 35 years The herbaceous component of the preserve area is represented by 92 species, including a large proportion (35%) of w~ed species that have colonized disturbed areas (i e , brush piles, trails and even gopher tortoise mounds). The most common herbs include broomsedge grass (Andropogon virginicus), CypelUti retrorsus, Dichanthelium sabu10rum, Innonence (Euphorbia p()lYl-'hil.!~), and hairsedge (Bulbostylis ciliatifolia). Average perl..ent I..over for the 8 permanent 1 x 1 m2 plots was 34% in 1987 and 30~ in 1988, showing a slight decrease which was largely attributed to a loss of broomsedge grass from the plots Even though the percent cover decreased from 1987 to 1988, the number of species within the 4 sampling plots increased from 15 to 19 This change was due to an increase in the number of scrub endemICS that have germinated throughout the preserve. Some of the more notable species include Bulbostylis, Lechea, Euphorbia, Dichanthelium, Aristida, Croton, and Liatris. Rudera1 components have invaded the margins of the preserve 6 due to past disturbance from livestock. Several horses clod goats from the adjacent property have periodically ent2red the preserve. This has resulted in some areas being cUIT,pletely denuded from horses rolling in the sand for insect fcutection. Also the adjacent properties have been disturbed for su~h a long time that the ruderal components are well established and potential seed banks are high SCRUB FINGERS OF PRESERVE #1 Approximately 4 acres of sand pine scrub was created 1n an effort to increase the total number of acres within the sand pine preserve A soil mulching technique utilized by the phosphate industry was used to recover 4 acres from former sand pine scrub slated for development on the project. To date, the establishement of scrub vegetation on these newly created ridges has been slow because of invasion by local pasture grasses and weeds, drought, and localized disturbance from livestoi...k With time, these areas within the preserve will eventually become recognizable scrub in the early stages of development ~nJ may be used to eliminate an equivalent amount of scrub from other co mm ere i allot s wit h in the pro j e ct. Howe IJ e r, SIn c e s c rub reclamation is in its infancy, this process may take ITldny years before these areas are acceptable to all parties involved PRESERVE #2 Historically, this tract of scrub vegetation shares a similar background with the preserve north of N W 22nd Ave. in that the understory was cleared in the early 1980's What's 7 interesting about this 14 acres is that regeneration at sand pine has bee n pro 1 i f i c . T his i n die ate s t hat the type 0 f 111 e c h ani c a 1 disturbance used to clear the understory vegetation in thIs portion of the scrub caused less disturbance of sOlI profiles when contrasted with the area to the north or conditiuns were more favorable for seed dispersal and/or germinatiun Most of the area north of N W. 22nd Ave. was ~leared with a root rake which caused severe mechanical disruption and alteration of soil profiles This type of clearing tends to remove a vast amount of underground roots and corms which would normally germinate with time It appears that the 14 acres south of the N W 22nd Ave. was mowed, raked, or bulldozed In a slightly different fashion since many more endemil:: species and sand pine have germinated over the past 5-6 years. The site is dominated by sand pine (pinus clausal which range in size from 15-41 cm dbh reaching heights of 16-17 meters. Most of the trees lean to the west because of offshore sea breezes Tree core data indicates that most of the ldrger sand pine range in age from 21-45 years (Table 2) Exi~ting sand pine densities within the preserve average about 45 trees per acre Sand pine recruitment from existing seed bank reserves and periodic release by mature trees has been prolific for this scrub Seedling densities range from 280 to 340 trees per acre. The shrub layer is dominated by scattered sand live oak (Quercus geminata.l, rosemary (Ceratiola ericoidesl, Palafoxia feayi, jointweed (Polygonella polygamal, saw palmetto (Serenoa 8 repens), and scrub mint (Conradina grandiflora.l (Tablt: 3) A large portion of the tract is covered with a dense mat of love vine (Cassytha filiformis) which has killed many scrub mints Most of the young rosemary appear to be about 3-5 years uld based on nodal counts. The herbaceous layer is composed of wiregrass (Arlstida gyrans), silkgrass (Pityopsis graminifolia), SClllD sedge ( R h y n c h 0 s P 0 ram eg a 1 0 car p a), h air s ed g e (B u 1 b 0 sty lis c i 1 i d t i f 0 1 i a) , sand spike moss (Selaginella arenicola), Dichanthelium abulorum, prickly pear cactus (Opuntia humifusa), natal grass (Rhynchelytrum repens), broomsedge grass (Andropogon ~.!..E.Sl.nicus), and sawbriar (Smilax auriculata) (Table 3). Within the sand pine scrub preserve, approximately 1 3 acres along the western edge of the site (Figure 2B) is best ~lassified as ruderal vegetation. It appears that these areas were once utilized as dump sites for building and residential debris These areas support a thick grass layer composed at several weedy ore x 0 tic s pe c i e s . The do m i n ant s p e c i e sin c 1 u deb a h i a 9 r ass (Paspalum notatum), broomsedge grass (Andropo~!:!. virg Inicus), natal grass (Rhynchelytrum repens), wild grdpl: (Vitis munsoniana), and pokeweed (Phytolacca americand) Other associates include dogfennel (Eupatorium capillifollum) I Caesar weed (Urena lobata), begger-ticks (Bidens alba), dwarf horseweed (Conyza canadensis), Sida cordifolia, periwinkle (Catharanthus roseus) and Brazilian pepper (Schinus terebinthifolius) (Table 3 ) 9 within the disturbed vegetation, open sandy areas are dominated by a mixture of sand pine scrub species, most notably, sand live oak, jointweed, pawpaw (Asimina reti~ulata), fetter bush, prickly pear cactus, palafoxia feayi, and tri::dd softly (Cnidoscolus stimulosus) (Table 3) MANAGEMENT PROCEDURES In the stated objectives for the management of the property, there are major responsibIlities for the longterm ~rts~rvation of the vegetation, wildlife, and soils, plus the ared' 5 natural resources In this role, the following comments ar~ reasonable judgements as to the management "state of the art", su that the preserves will be sufficiently protected for the future and not just short-term realities. Assessment of impact and management recommendations are based on field observations, comparison of past records, and a review of pertinent literature Fire Management Fire has a necessary historical role in the perpetuation of sand pine scrub and maintaining its diversity 0f Jegetation Manis efforts to suppress fires and the development of fIrebreaks provided by human activity (i e , roadways) have createJ the need for i n v est i gat i n 9 pre s c rib ed bur n i n 9 pro 9 ram s tom a HI t a ins and pine scrub. Maintenance of sand pine forests fIt a general classification scheme where high intensity crown fires occur only once in the lifetime of sand pine or about every 30-60 years (Harper 1915, 1927; Webber 1935; Laessle 1958, 1967; Christensen 10 1981) and have virtually defied man's control efforts (Johansen and Cooper 1965; Hough 1973) Plow-lines are ineffective and actions of people, equipment and tools on the grou~d ar8 usually f uti 1 e . Due tot h e pot e 11 t i a 1 d e vas tat ion 0 f the set y pe s 0 f wildfires, attempts at fire suppression have been tLe norm In Florida for more than 30 years. The unpredictable nature of these fires, their infrequent occurrence, and the lack of information on conditions favorable for planned ignition in scrub habitats, have not allowed for the application of prescription burning. Except where sites were totally mechanically prepared and treated as slash burns as in the Ocala National Forest, to date, there are only a few examples of prescribed management tires that imitate a control crown fire in sand pine scrub ClJllIH1l1nities (Cooper 1972) (which are found in central and southern Florida dominated by pinus clausa var. clausa). Winter preser ibed fires have been used extensively with much Sllccess In the Choctawhatchee sand pine communities (which are found in northern Florida dominated by pinus clausa var immuginata), as the understory fuels associated with this community are light and pro d u c e 1 0 ",t1 i n ten sit y fir e sat t his t i me 0 f the ye d r ( Coo pe r 1972) However, wildfires continue to be the rule and literature on prescribed burning in sand pine scrub is limited Recently, Doren et. al (1987) successfully burned two separate sand pine scrub preserves in Boca Raton using a modified fuel model to develop an effective prescription for burning sand 11 pine scrub under controlled conditions The results of these controlled burns suggest that an effective, safe mtans exists to burn sand pine scrubs in a developed landscape, prov Idlng this option is available without smoke management problems and if weather conditions dictate prescription burning of tbe Quantum Park scrubs is possible Management options for these two preserves range from a decision 1) to do nothing and let nature take its course; 2) to manage for the maintenance of a viable scrub ecos1stem, which implies the natural biota, or 3) to focus management on the needs of one or more species The decision to emphasize eco~ystem or species management depends on the entity responsible for management, type of preserve, management objectives, area of the preserve and the nature of the surrounding lands Within the sand pine scrub preserves of Quantum Park, the management objectives should focus on 1) maintenance dt normal ecosystem processes which include the perpetuation of endemic scrub plants and animals, 2) the conservation of leLal soil characteristics which support the vegetation, 3) maintenance or restoration of normal hydrologic conditions, and 4} the prevention of establishment of exotic species Prior to the formulation of a step-by-step approaLh for the maintenance of these two preserves, it has been decided that each preserve will be divided into several smaller components in order to provide mixed stands of different ages. Based on the life history characteristics of the sand pine (Pinus clausal and 12 rosemary (Ceratiola ericoides) , a 3~-5~ year burn cycle has been adopted for this study. This was based on the specific mortality traits of sand pine (senescence at 5~-6~ years) and rosemary (senescence at 2~-3~ years). To further age each preserve, tree core data was gathered from randomly selected sand pines scattered throughout each preserve (Table 4) Using this data, the scrub community of each preserve was divided into definable tracts that will be used to maintain the ecological Jiversity of the scrub (Figures 4A and 4B) FUEL MODEL The chaparral/high pocosin/mature shrub model (NFFL Model 4) (Anderson 1982), was considered suitable as a base for developing a f u elm 0 del for the san d pin e s c rub co mm u nit y i n c e n t r a 1 and south Florida (Table 4) NFFL Model 4 presupposes a brush/shrub f u e 1 un d e r s tor y six 0 r m 0 ref e e t h i g h, f 1 a mm a b 1 e f 0 1 1 age, a nearly continuous secondary overstory, with heavy loading of live and dead fine woody materials Except for the more scattered understory, this is very similar to the sand pine scrub of the Quantum Scrub and seemed likely to be accurate in predictions of fire behavior in these fuels Unlike some of the western brush types, which can usually be burned quite successfully under less than extreme conditions (Wright and Bailey 1982), sand pine has been virtually impossible to prescribe burn, and rarely burns except under the most extreme conditions (Cooper 1972). Prescription parameter development for a sand pIne scrub burn in southeastern Florida was based on a number of restrictive 13 conditions relating to each scrub site both prestl:ves are surrounded by local or large scale development, preserve #1 is adjacent to a proposed city park, and preserve #2 will be surrounded by industrial or commercial lots and possibly a hotel to the north. For permitting purposes, the stagnation Index was required to be below 7 (Florida Department of Agriculture 1976) Environmental parameters used to establish fire behavior predictions needed to provide for a reasonably intense fire in order to ensure that the sand pine scrub fuels would burn, yet be of moderate enough nature to be relatively certain of having ace e p tab 1 e fir e be h a v i 0 r and s mo k e co n d i t ion s l' he follow i n g ranges of prescription parameters will be used in tbe scrub model midflame windspeed of 3-7 mph; wind direction easterly- southeasterly; relative humidity 45%-60%; 1 hour dead fuel moisture < 11%; live woody fuel moisture 25%-75%; dry bulb temperature 75-85 OF; and cloud cover < 10% Values outside of the indicated ranges were also tested in the model but tound to be unacceptable (Doren et. al 1987). Fuels like the chaparral, which contain hIghly volatile compounds (we considered sand pine scrub such a fuel) require more preparation for prescribed burning than other fuel types (wright and Bailey distance of 0 4 miles 1982) Because of the maximum spotting (0 64 km) and a Probability of Ignition of 70, some site preparation will be considered necessary in order to ensure a successful burn and protect the values at risk SITE PREPARATION 14 Three to four weeks prior to each burn, 10-20 m wide strips around each proposed burn site will be crushed using a small empty, roller drum-chopper (Model SL-7, Marden Manufactur ing) One pass over the vegetation, with drums set parallel to each other, will be sufficient to produce a light slash, without appreciable soil disturbance or fuel compaction A narrow (2-4 m wide) fire lane will be established around each preserve prior to each burn in order to prevent the possibility of a fire escaping into adjacent development lots. All of the sand pines within the chopped area will be dropped into the site to prevent spotting and to create hot-spots to help prepare a seed bed and open areas. Approximately 10-15 days will be required without rain in order to dry out the crushed fuels sufficiently and reduce fuel moisture to prescribed levels. Within Preserve #1, the dry prairie/pine flatwoods areas will be burned separately from the canopied areas of scrub Due to the nature of the dry prairie, it may be necessary to herbicide some of the grass pre-burn in order to stimulate the seeding of scrub species from the existing adjacent ridge The sand pine fingers will not be regularly burned for at least 20 years except in areas now dominated by bahia grass The most southern finger has been invaded from the west by bahia grass, nut sedge, and Ceasar's weed These three species indicate that soil conditions may not be suitable for longterm scrub survival since bahia grass will most likely out-compete early scrub colonizers In an effort to eradicate these 15 troublesome species, areas of bahia grass will be herbi~ided and then mulched with hay or other suitable materials in order to increase fuel loads. The area will then be burned dnd a thin layer of scrub top soil will be broadcast over the burn~d areas. This should help the establishment of scrub species Since these species are scattered over other areas within the scrub fingers, herbicide without mulching will be used on a local scale The entire area will be seeded with sand pine which can be purchased through the Division of Forestry Small scrub oaks and other nursery grown stock will be planted to form small islands within each of the fingers Since the oldest trees occur in the northeastern corner of the sand pine scrub of Tract #1, the interior core of the oldest trees will be left standing for the burn The sand pine around the fringes will be dropped in place after the area 1S roller chopped (Figure SA). The remaining areas will also be chopped, however, no sand pine will be felled. This will allow seed input from the trees left standing as a result of seed release following the fire. Tract 2 will be roller chopped in a similar fashion to that of Tract 1. Two small islands of vegetation will remain standing with no mechanical alteration. The other areas will be roller chopped and the sand pines dropped in place (Figure 5A) In order increase diversity and to prevent the unaltered areas from ignition during the burn, these areas will be watered by a temporary sprinkler system at least one day pre-burn. This will 16 increase the water content of the vegetation and make it difficult to ignite. Burning will occur between the months of December and February, following a wet month If drought conditions prevail prior to the scheduled burn and the drought index is high, it should be postponed until condItions favor a controllable fire The exact firing pattern of the burn will be decided by the burning agency (i e., Division of Forestry, private firms, or local government) on the day of the burn Head fires will be used were applicable to simulate the fire behavior (and effects) of naturally occurring fires, and to ensure as complete a burn of the vegetation as possible All existing structures (i.e , boardwalks, fence posts, etc) that may have been constructed within the preserve at the time of the burn should be protected by herbiciding in advarll_e of the burn and then raking down to mineral SOlI to remove d~bris from around the structures. This would reduce the fIne fuels necessary to carry a ground fire Since the site is currently being utilized as a relocation site for gopher tortoise and Florida mice, all burrows should be flagged prior to roller chopping. If the preserve is fenced at the time of the burn, access should be made to the closest point of entry by removing a section of fence to reduce damage to the remaining unburned areas and reduce soil disturbance This can be coordinated with the on-site property association and the City of Boynton Beach. Preserve 12 was also divided into 2 separate burn areas 17 (Figure 5B) based on the natural contours and the existing disturbed areas within the preserve. Each burn site will be roller chopped in a similar fashion as Preserve #1 so that small islands of standing vegetation remain (Figure 5B). All sand pine on the margins of each tract will be dropped in place to prevent spotting in nearby vegetated areas The fuel model and prescription used on Preserve #1 will also be utilized fur these burns. A temporary watering system will also be utilized for those areas that will not be burned. BURN SCHEDULE The following burn schedule will be utilized for the sand pine preserves at Quantum Park Preserve #1 Tract # 123 Preserve #2 Tract # 1 2 Year 1988 1993 1998 2003 2008 2013 2018 2023 2028 2033 2038 2043 2048 2053 2058 2063 x x x x x x x x x x x x x x x x x x x x x x x The burn schedule was design to fit the existing age distribution within each sand pine parcel The sand pines within Tract #1 of preserve #1 average about 30-35 years of age. Since this is the oldest portion of the scrub on this ridge, burning will occur in 18 20 years when the trees begin to reach senescence Some of the older trees will be left to reach old age without the effect of burning Seeding into the burned areas will occur from the existing margins of the scrub. Tract #2 will be burned in approximately 30 years when the trees reach maturity. The dry prairie/pine flatwoods community will be burned every 5 years in order to stimulate new growth of herbs and grasses for local gopher tortoise populations Areas within the prairi~ that are invaded by scrub species will be excluded in the followIng burn year This will promote the development of scrub islands within the dry prairie system The exact areas to be excluded in each subsequent burn will be decided by the City Forester or a private consultant prior to the prescribed burn. Sand pine within Preserve #2 range in age from 11 37 years with an average age of 19 5 years. Since no age specific distribution exists within this preserve area, the site was randomly divided to be burned on a 30 and 50 year rotation, beginning with tract #1 of preserve #2. Tract #2 will be burned in the opposite rotation sequence (50 and 30 years) to allow for ecological diversity for local wildlife and plants AGENCIES AND MATERIALS FOR BURNING Prior to each burn, a permit for burning will be obtained from the city forester. The burning will be coordinated with the city fire department who may be able to assist with fire protection equipment at the time of the burn The State Division of Forestry will be contacted to disk existing fire lanes or to 19 create new lanes depending on the conditions of the surrounding fuels and vegetation. If used, all fire plowing will te kept to a minimum depth (3 to 6 inches) The burn will be conducted by a private agency such as Forest Resources Management, 1528 Hendry Street, Fort Myers, FI 33901. Depending on the weather conditions on the day of the burn, the Florida Highway Patrol will be notified about possible smoke problems on 1-95 Crew size and equipment will be determined by the agency conducting the burn. The estimated cost, based on 1988 figures, for the above work will be about $8,000 00 for burning 10 acre blocks. The cost for burning less acreage may be slightly less, however, mobilization costs will be very similar. The above cost estimate includes any changes necessary to the burn plan, chopping the site, coordination with local and state agencies, man-power to conduct the burn, and permit acquisition from city and state agencies. The cost, based on 1988 figures, for burning the dry prairie will be about $1,500 to $2,000 for coordination, permits, and on-site burning. If burning turns out to be an unacceptable means for maintaining the existing scrub, due to smoke management or excessive explosive fuels, then mechanical means such as roller chopping will be utilized. This alternative method will require an empty roller chopper that will bend and break the vegetation near ground level, causing minimal soil disturbance. The use of a water filled chopper would cause severe soil disturbance which could effect the longterm survival of these scrubs The chopped 2~ vegetation would then be removed from the site to allow scrub regeneration. Since most of the seed trees would be removed, these areas could then be seeded with sand pine by using the methodology utilized in the Ocala National Forest Mtchanically seeding some areas and not other would provide scrubs ot various age classes, a benefit for longterm survival of many of the scrub animals Implementation of the above management plan will require the financial commitment from the local property association and the commitment by the City of Boynton Beach. 10 contrast tQ the above sctub man~9Ql\lCllt plan, approximately 1.3 acres of ruderal vegetation within preserve #2 should be immediately altered to allow the establishment of scrub vegetation. These previously disturbed areas along the west edge of the site should be herbicided, mulched as described above and burned. A thin layer of scrub soil could then be scattered over the burn areas and then the area seeded with sand pine Prescribed burning would require the formation of a sandy fire break between the existing scrub and the ruderal vegetation Burning should occur when the winds are out of the east to prevent smoke management problems on the interstate highway This would force the flame front to the west, away from the sand pine scrub vegetation Once the disturbed areas have been burned, sand pine seeds should be broadcast and slightly trenched into the sand about 2 inches. Other trees such as sand live oak could also be planted 21 in these disturbed areas to simulate oak thickets which could be utilized by scrub jays as suitable nesting sites Observations from other scrubs indicate that oak thickets with as few as 5 trees have been utilized as nesting sites by scrub jays Two small oak thickets will be planted within the disturbed areas Each thicket will be planted with 5 field grown sand live oaks which range in height from 5-7 feet. The trees will be placed in a pattern to produce a dense canopy required for nesting The burning of the ruderal vegetation within preserve 12 w 0 u 1 d r e qui rea pe r m i t fro m the C i t Y For est era n d coo r din a t ion with the City of Boynton Beach fire department. EXOTIC PLANT REMOVAL One of the most serious threats to any native plant community in south Florida is the invasion of exotic vegetation Exotics can modify normal ecological processes or relationships, including predator-prey and herbivore-plant relationships, nutrient and energy cycles, and soil-building and erosion processes. It has also been shown that the general stdbility of Florida's natural communities is also reduced. Brazilian pepper (schinus terebinthifolius) and punk tree (Melaleuca quinquenervia) do occur within the preserve areas An on-going treatment program was initiated on the 20 May 1987 by treating the base of each shrub or tree with herbicide (Garlon 4). The eradication process will be extended to all non-scrub species throughout the preserve areas in order to reduce unwanted seed banks which may affect the long-term survival of the scrub 22 community. The above management plan provides a step-by-step program to fulfill the requirements of the Development order and the Treasure Coast Regional Planning Council. Modifications to the above plan may be in order as new information becomes available concerning the fire ecology of the sand pine scrub community. 23 Figure 1.

If you have any comments or require changes, please indicate on your copy or in a letter.. Thank you for your cooperation. Sincerely, ,,(/~ ~Ld?' - Donald Richardson, Ph.D. DRR/jlr EXOTIC REMOVAL FROM NONJURISDICTIONAL WETLANDS WITHIN THE QUANTUM PARK DEVELOPMENT, BOYNTON BEACH. · Revised As specified in the Department of Environmental Regu1ntin" Permit '581269989 under Specific Conditions Numbers 5 and 6, ~l' exotic vegetation will be removed from the wetlands and replanteu with hardwood swamp species. Specific item Number 6 requires the locations, numbers and species of plants that will be removed and a list of those to be installed. The fOllowing report details a plan to remove the existing punk trees (Melaleuca quinquenerviai from both wetlands. After a close examination of both systems, the southern wetland (2.2 acres) is dominated by two dense stands (0.11 acres) of punk trees on the northwest corner and western edge. A smaller group of trees were also found within a 20 foot l}and along the southeast and eastern edges of the wetland As per the requirements established within the DevelopmenL Order, most of the fringing Me1aleuca trees (ca. 361) were removed from the wet land. Each tree was removed from the berm with a front end loader and a chain. This would preclude the need for heavy equipment in the wetland since the peat lay(>r-:: exceed 4 feet in many areas. The dense stands required special consideration since they extend out into the wetland beyond the limits of the heavy equipment. A berm was constructed out into the wetland several meters in order to reach the southern extent of the Melaleuca head. The trees were also removed as indicated above. All berm -t. I. materials were removed to existing grade to allow germination . from existing seed sources. Under the present water conditions, most of the naturally occurring herbaceous species ~~olll~ germinate from the existing muck layers. Isolated trees within the wetland (ca. 89 saplings) will uc treated with the herbicide, Arsenal. This herbicide was requested for use at Quantum Park by the Florida Department of Agriculture. Arsenal has been used effectively for control of Melaleuca and Brazilian pepper within Florida. Pr ior to the treatment of isolated Melaleuca trees, the water table within the wetland will be slightly lowered to within a few inches of the muck layer or applied during spring drought conditions. All treatments will be administered so that no herbicide reaches the water table. Application to Melaleuca will be done u3ing ~~~ frill/girdle technique as indicated in the Supplemental La..H:l.L..'-,;, report (EPA SLN No. FL-87001U for Arsenal. Since most of the trees are less than 6 inches in circumference, approximately 50% of the bark will be removed and a cut made into at least two growth rings. Undiluted Arsenal will be brushed into eacD cut Re-application may be required for those trees that ar~ ~~ killed during the first treatment. The above protocol for exotic removal would require the installation of some hardwood tree species. Understory ferns and herbs will recolonize these areas within several months Only in areas which do not respond to natural germination will wax myrtle (Myrica cerifera), dahoon holly (Ilex cassine) or red bay (persea 3 palustri~) be installed. All trees (3 gallon nursery grown stock) will be installed on 10 foot centers or in small clumps to simulate the natural landscape. Approximately 48 trees would bp required based on the 0.11 acres of Melaleuca removed. After ~h~ area has been cleared of Melaleuca, any exposed soil will be lowered to grade elevations in order to prevent Brazilian pepper colonization. The 3.8 acre wetland adjacent to the City Park is dominatea by 0.20 acres of dense Melaleuca. Most of the existing Melaleuca trees (ca. 300-500 trees including saplings) occur in the southwest corner of the site and average 3-8 inches dbh, becoming smaller to the east. The remaining trees are located in a small stand in the northeast corner of the site. To date, the dense stands of Melaleuca as referenced a~ov~ have been removed from the wetland. Isolated trees will be treated using the frill/girdle technique as described in the Supplemental Labeling report for Arsenal. A copy of the Supplemental Labeling report for Arsenal has been included in t his r e p 0 r t . The sam e pre c aut ion s reg a r din g sur f ace \0' ate r conditions will be followed for this wetland during the treatmer.~ phase of the project. The natural vegetation of this wetland is dominated by several herbaceous species and scattered wax myrtles As stated above, no herbaceous planting would be initiated unless natural recruitment does not occur. Approximately 89 trees will b~ installed in the former Melaleuca areas. A mixture of wax m~_~lc 4 (Myr lca cer 1 fera), red bay (persea palustris) and dahoon hol.1.Y (Ilex cassine) will be planted on 10 foot centers or in small -- clumps to simulate natural swamp development. There has been some discussion suggesting that a possiblA alternative would be to completely remove the wetland and replan~ wi th na t i ve spec ies. Muck layers in these wet lands ex ceed .J-,* feet in thickness; thus requiring some form of de-mucking for removal of the exotics. The muck would later have to be installed to proper elevations and replanted with both natiu~ trees and herbs. This type of exotic removal may stimu:~_~ Melaleuca establishment in the wetlands and therefore, a poor altenative to preservation of an already functioning wetland. A maintenance program would be initiated to curtail possible exotic recruits or to further retreat those trees that might not have been killed during the initial treatment with herbic de Since this herbicide will be applied during low water and by hand, death the other woody species will be held to a minimal level. Maintenance will occur every 6e days in order to treat new seedlings or to retreat saplings that were not killed during the first application. All monitoring reports will be submitted to the deve'r'J'"'....~ of the property for submittal to the required ag2.C~~ . Monitoring will occur semi-annually for the first and secono year. Monitoring reports will include percent mortality of treated exotics, percent cover by natural wetland species, and survival data on planted trees. Color photographs will be used 4 to document the elimination of exotic species from the wetlands. All Melaleuca trees were removed from the wetlands by the ~ 7 Ryan Corporation. Trees were placed in piles and allowed to dry for several weeks. All Melaleuca will be burned on site in large earthen pits supplied with forced air to reduce carbon format;or and smoke. This method has been excellent to contro' r-;Y'"1r' problems which may affect local neighborhoods or Inters~a~~ traffic. ~ ~ i :1 il I (EPA REG. NO. 241-273) _.... : ~- -- . L : '-EPA 8LN NO.
