Advantages and Disadvantages of Different MFL Approaches for Biscayne Bay
Northern Biscayne Bay Sub-region
POTENTIAL APPROACHES APPROACH SCORE
(Cumulative Total)
Seatrout & manatees have public appeal
Reasonably good existing database
Little public interest in Johnson's Seagrass
Relatively easy to ID Significant Harm Critical habitat already designated Yes - Data already being compiled
A lot of scientific work already done
Seatout not currently abundant
Difficulty in monitoring minimal changes
Existing conditions are highly variable Difficult to quantify "vitality" of seagrasses Yes - Data already being compiled
Few shoreline mangroves
Would prevent continued degradation Yes - Data already being compiled
Would maintain existing depauperate fishery
Likely significant public opposition Likley significant public opposition
Would maintain a viable fishery Public acceptance Lack of scientific base to work from Expensive and long term
Common scientific tool Not developed for Biscayne Bay May be useful with much further study Not understandable as real Expensive and long term
Common scientific tool Not developed for Biscayne Bay May be useful with much further study Impacts from acts of nature (e.g., hurricanes) Very expensive and long term
Would require additional shorline vegetation
Relatively easy to monitor No soils present
Nearly entire shoreline bulkheaded
Potential difficulties in relating population
declines to reductions of fresh water flow
Enhanced knowledge of H. johnsonii
could cause permitting problems
Designated critical habitat for manatees
and Johnson's seagrass
Potential difficulties in relating population
declines to reductions of fresh water flow

Population declines may be unrelated to
reductions in freshwater flow
Restoration to pre-development
conditions would be too expensive and
not likely politically viable
Inexpensive, but difficult to interpret
Existing condition is somewhat degraded, but
Significant Harm not yet reached 3 2
General ineffectiveness of existing regulatory
programs
Would require add'l approach for
open-water areas
