Explanation - For each species, an indication is given as to whether that species is reported for
a specific section of the Bay, and if present, how much life history and population information is
available. * indicates present, but with little information. ** indicates present and some
information and *** indicates present with a good set of local life history and population or map
location data. If no * is present, it means we could find no record of the occurrence of this
species in this part of the Bay. The existing data base in Biscayne Bay for freshwater sensitivity
of a given species is reflected in the same way: S = some information, SS = good information,
SSS = detailed information, no S = no information.
Potential Alternative Approaches for MFL Development for Biscayne Bay
Freshwater Flow and Ecological Relationships in Biscayne Bay 5-12
Appendix D Tables D-1 to D-6 take the analyses one step further by rating each
of the potential indicator species for seven characteristics to determine usability
as an indicator species. These seven categories were: presence/absence in the
sub-region, sensitivity of applicable parameters (salinity), reliability of response,
rapidity of response, ease and economy of monitoring, meaningful feedback to
management and importance of endpoint. If a species was not reported to exist,
or existed in too small a population to be usable as an indicator species, it
received no further consideration. If it was present in suitable populations, it was
rated for the remaining six categories. The scale for each rating was 0-5, with 0
indicating a poor response by this species for a given usability factor, 3 a medium
response, and 5 an excellent response. Thus for species present in a sub-region, a
maximum value of 30 could be achieved with these analyses. The highest rated
species were highlighted in the tables and for each region were: the American
oyster (Oleta), shoalgrass, manatee grass and spotted seatrout (Northern), forams
and diatoms (Miami River), shoalgrass and pink shrimp (Central), shoalgrass,
pink shrimp and spike rush (South-Central) and American crocodile and Roseate
spoonbill (Southern).
PRESENCE/ABSENCE/VITALITY OF POPULATIONS OF INDICATOR
SPECIES
From the analyses in Tables D-1 to D-6, it is apparent that while
presence/absence data is available for a suite of indicator species, details on
population sizes and vitality of those populations is generally lacking.
Monitoring population sizes is difficult and expensive and has not been
undertaken for any but the most easily visible and typically charismatic species,
such as the manatee. For this reason, this approach to establishing MFLs did not
rate high in the individual analyses by sub-region. (Appendix E Tables E-1 to E6).
PRE-DEVELOPMENT SCENARIOS
When an estuary has a very low level of anthropogenic impacts, establishment of
MFLs may look at the pre-development conditions for the estuary and watershed
and determine if it is possible to restore some or all of the pre-development
estuarine functions. Given the level of development in all the watersheds in
Florida, this is not a common approach. Mattson (2002), however, describes the
approach to the management of freshwater flows in the Suwannee River estuary
