Revised: April 13. 1992 ENVIRONMENTAL MONITORING PLAN -HAYNES WILLIAMS CITRUS PROJEcr OKEECHOBEE COUNTY, FLORIDA This environmental monitoring plan is proposed to evaluate the condition of preserved wetlands and forested uplands to be incorporated into the water detention area at the proposed Haynes Williama Citrus Project, located within sections S-8, T34S/R34!, in north central Okeechobee County. In addition, this .program will evaluate changes occurring in transitional grassland habitat to be restored to functional wetland• by inclusion in the water detention area, for a period of _five years fo~lowing base-line evaluation. The project will contain one water detention area of approximately 106 acres in size. Water control elevations will be maintained at desirable levels for retaining and improving wetland hydroperiods, and to restore wetland character to previously drained wetl~nds. The following components are proposed for this program. TASK #1. Environmental Monitoring Environmental monitoring will consist of two components: vegetation and wildlife. Vegetation: Three permanent transects will be established through existing upland, wetland and restored transitional habitats within the water detention area, as depicted -in Pigure 1. Transects will measure approximately 600 to 800 feet in length, and will be marked by PVC covered poles at the beginning, end and 200 foot increments alone the line. Sampling of vegetative characteristics alone the transects will be accomplished by documentation of species presence and percent cover within one square meter quadrats placed at 25 foot increments along the transect. Water depth will be measured for later determination of actual land elevation at each station. A photographic record will be maintained of the detention area by establishing two photo reference points atop the levee for taking panoramic photographs. Panoramic photos will consist of slightly overlapping photographs, covering a 180 degree or greater sweep: taken with SO an lensand 35 um color print film format. Associated wildlife: The detention area and surrounding grove habitats will be surveyed for -the presence or signs of mammals, reptiles and avifauna during vegetation surveys. Special emphasis will be placed on threatenec;l species obs:erved on the site prior to project development. TASK 02. Hydrology A staff gauge will be placed in the v1c1n1ty of the outfall control structure, and referenced to feet NGVD in accordance with the design elevation of the weir crest. Readings of water levels will be taken weekly by grove personnel, and forwarded to the environmental consultant. The water regime influencing existing and restored wetlands will be described as stage hydrographs, and inundation EXHIBIT 12 a


duration periods. Water levels along the transects will be referenced to staff gauge rea4ings to calculate ground elevations. Daily rainfall will be measured from at least one location in the grove, and provided with annual reports. TASIC 03. Annual Reports Vegetation samplina and wildlife surve7s will be conducted on an annual basis. The initial report will be considered the ~•••-line aaainat which future changes are compared. The baseline assessment will be conducted prior to construction of the water detention area. Subsequent annual monitoring will be conducted during September-November for five consecutive years following base-line evaluation. Reports will be submitted' to the client and South Florida Water Management District within 60 da7s of sampling. Tables of flora and fauna sampled will be presented, along with detailed sampling methodoloa, tabulations/ graphs of water levels and rainfall, and copies of panoramic photographs. Discussions of pertinent trends will follow the results, and if warranted, recomnendations will be proposed. EXHIBIT 126
