Community Structure - 62-345.500(6)(c), FAC PART II – Quantification of Assessment Area (impact or mitigation) (See Sections 62-345.500 and .600, F.A.C.) Site/Project Name Application Number Assessment Area Name or Number 2. Benthic and Sessile Communities Impact or Mitigation Scoring Guidance The scoring of each indicator is based on what would be suitable for the type of wetland or surface water assessed Optimal (10) Condition is optimal and fully supports wetland/surface water functions Assessment conducted by: Moderate(7) Minimal (4) Condition is less than optimal, but sufficient to maintain most wetland/surface waterfunctions Assessment date: Minimal level of support of wetland/surface water functions Not Present (0) Condition is insufficient to provide wetland/surface water functions This indicator is intended to be used in marine or freshwater aquatic systems that are not characterized by a terrestrial or emergent plant community. These systems include live hardbottom communities, such as oyster bars and beds, reefs, and soft-bottom systems such as riverine systems. w/o pres or current .500(6)(a) Location and Landscape Support with Oyster bars and beds in nearshore habitats and estuaries filter large amounts of particulate matter and provide food and habitat for a variety of species, such as boring sponges, mollusks, and polycheate worms. .500(6)(b)Water Environment (n/a for uplands) w/o pres or current w/o pres or current current or w/o pres with .500(6)(c)Community structure 1. Vegetation and/or 2. Benthic Community with Score = sum of above scores/30 (if uplands, divide by 20) Seven attributes are considered to generate the score for “Benthic and Sessile Communities” with If preservation as mitigation, Preservation adjustment factor = Adjusted mitigation delta = For impact assessment areas FL = delta x acres = The distribution and quality of coral reefs reflect a balance of water temperature, salinity, nutrients, water quality, and presence of nearby productive mangrove and seagrass communities. Benthic infauna of soft-bottom systems stabilize the substrate, provide a food source, and serve as useful indicators of water quality. All of these communities are susceptible to human disturbance through direct physical damage, such as dredging, filling, or boating impacts, and indirect damage through changes in water quality, currents, and sedimentation. Delta = [with-current] If mitigation Time lag (t-factor) = Risk factor = For mitigation assessment areas RFG = delta/(t-factor x risk) = Form 62-345.900(2), F.A.C. [effective date 02-04-2004]

Benthic and Sessile Communities (continued) Seven attributes are identified in the UMAM Rule to evaluate the “Benthic and Sessile Communities” section of this category. To provide guidance, examples that depict variation in conditions for each of the attributes are included. • Species number and diversity of benthic organisms • Non-native or inappropriate species • Regeneration, recruitment and age distribution • Condition of appropriate species • Structural features • Topographic features such as relief, stability, and interstitial spaces (hardbottom and reef communities) or snags and coarse woody debris (riverine systems) • Spawning or nesting habitats Be aware that not all attributes are applicable to all assessment areas and in some cases, some attributes may be more relevant than others.
