RECOMMENDATIONS We strongly urge that the local government come to a decision on the use to which the Mangrove Lagoon is to be put. The present course of development in and around the area increases pressures daily on this unique ecosystem. Because of the lack of a stated objective for the area, continuing development and shoreline alteration is destroy- ing this area as a basic production, prime recreational and as a research site. Its value for these purposes is being lost by default. The uniqueness of this environment on the island,with its presently healthy and varied complex of habitats,pro- vides a site of significant natural value for which esti- mates of the esthetic and economic worth have not yet been constructed. Its destruction, however, can have decisive and far-reaching effects, many of which cannot be predicted and some of which are likely unimagined. In recent years detailed productivity studies and va. te analyses have been accomplished for particular open coastal submerged lands, mangrove swamps, and river swamps, and for the first time a total resource worth has been described for some of the coastal zones of the states of Florida and Georgia. These value estimates range from $300 per acre Page 31
