This project encompassed two major areas; portions of the Moonshine Creek and Blues Creekwatersheds, and the northern quadrant of the Preserve north of Sanchez Prairie. Since the original parkacquisition in 1974, there have been several additions to the Preserve. This proposal lies within an 809-acreparcel purchased in 1994. This parcel was the headquarters for a dairy operation during the 1950s and laterthe site of an extensive tung oil orchard. Many of the tung oil trees have persisted, especially those along theslopes of the many relatively undisturbed sinkholes and ravines in the area. This species continues to be themost widespread of the exotics described for this project, covering approximately 450 acres in total. It hassteadily invaded the northern slopes of Sanchez Prairie over the years, and the potential for continued spreadinto and through the prairie lowlands is very high. The stand density varies from low at outlying spots tovery high in locations close to the old orchard operation.Target PlantsMelia azedarachCinnamomum camphoraAlbizia julibrissinAleurites fordiiWisteria sinensisRicinus communisCitrus spp.Lagerstroemia indicaCommon NameChinaberrycamphor treemimosatung oil treeChinese wisteriacastor beancitruscrape-myrtleFLEPPC RankCategory ICategory ICategory ICategory IICategory IICategory IIn/an/aTreatmentbasal barkbasal barkbasal barkbasal/hand pullbasal barkbasal barkbasal barkbasal barkHerbicideGarlon 4Garlon 4Garlon 4Garlon 4Garlon 4Garlon 4Garlon 4Garlon 4A basal bark herbicide treatment is quick and effective in dense stands of exotic trees.109

The park is listed as anOutstanding Florida Water, a National Natural Landmark, and a Priority Wetland Species Use Area. Thepark has a national reputation for the abundance and diversity of its plants and animals. With its large size,the park is the central piece in the Orange Creek Corridor of public lands, which stretches over forty miles,extending from the Santa Fe River in the north to the Ocklawaha River to the southeast.This project targeted Chinese tallow. The total project size is 312 acres; however, the project was dividedinto four phases with one phase proposed for each of the next four years. Each year the project site will bedivided into two parcels. One parcel will be treated by a contractor and the other will be treated by park staffas an in-kind contribution. The total project is divided into 120 acres to be contracted and 192 acres to betreated by staff. Phase I, treated this year, included 25 acres under contract and 20 acres treated by staff.Most of the project area was covered with a practically impenetrable thicket of small trees, shrubs, briars,and vines that virtually precluded normal access. To facilitate contractor access and to initiate restoration ofthe site, staff used heavy equipment (chopper and tree cutter) to cut paths through the project site. Thesepaths were laid out in grid and maps of the grid provided to the contractor. Paths will be suitable for foottraffic but will be too rough for use by vehicles. After treatment of exotics, the site will receive additionalchopping and a prescribed burn to facilitate community restoration. As the site is opened up by exoticscontrol, wetter spots along drainage channels are expected to be invaded by wild taro (Colocasia esculenta).Wild taro is a Category I invasive exotic and will be treated by staff as needed. Prior experience with wetprairie restoration indicates that the soil seed bank will prove adequate to restore native vegetation and arevegetation program will not be necessary.Target PlantsCommon NameFLEPPC RankSapium sebiferumChinese tallowCategory ICinnamomum camphoracamphor-treeCategory ITreatmentbasalfoliarbasalHerbicideGarlon 4Garlon 4Garlon 4111

Preliminary assessments indicate that Brazilian pepper has not spread east ofHighway 19. County lands are contiguous with state and federal conservation lands around Hernando Beach,Weeki-Wachee Preserve, Chassahowitzka National Wildlife Refuge, Aripeka, and Bayport. Brazilian pepperwas targeted in the following areas: Pine Island (McKethan) Park, Bayport Park, Hernando Beach Park, JenkinsCreek Park, Hernando Beach boat ramp, and spoil islands. The treatment areas included spoil islands and a100-foot swath along each side of trails, driveways, rivers, creeks, and parking lots. Hernando County hasadopted an ordinance to ensure long-term control of Brazilian pepper. The control of this species relies on theordinance and enforcement, plus the ability of the county to attract new partners to assist with the costs of thephases of this proposal.Target PlantsSchinus terebinthifoliusCasuarina equisetifoliaAlbizia julibrissinPaederia foetidaKoelreuteria elegansCommon NameBrazilian pepperAustralian pinemimosaskunk vineflamegold treeFLEPPC RankCategory ICategory ICategory ICategory ICategory IITreatmentbasal/hand pullbasal barkbasal barkfoliarbasal barkHerbicideGarlon 4Garlon 4Garlon 4RoundupGarlon 4The Bayport (left) and Pine Island(below) sites.

Silver River is a firstmagnitude spring-fed stream that flows into the Ocklawaha River. The park encompasses the river and overfourteen natural community types. Cogon grass occurs throughout the Pine Flatwoods and is invading thehigh quality, endangered Sandhill. Cogon grass occurs in various concentrations, from relatively continuouscoverage to small patches, in areas accessible by roads. Portions of the flatwoods community do notpresently have cogon grass, but the potential for cogon grass to spread into the unaffected flatwoods areas isextremely high. This project worked to contain the further spread of cogon grass into the park’s flatwoods.This was a cost-share project with the Florida Park Service contributing 5,000 toward the project cost.
