TEAS, HOWARD J. Department of Biology, University of Miami, Miami, Fl. 33124. - Restoration of mangrove shorelines in the USA.
Mangroves play an important role in estuarine ecological systems, as
well as shoreline stabilization. Large extents of mangroves have been
lost in the past century by dredging, land-filling, and pollution.
Thus, it is important to develop techniques for restoring or replacing
mangroves. It is suggested that future destruction of mangroves be
permitted only if they are subsequently replaced at either the same
site or at some appropriately developed alternative site. Mangroves
have been planted on a series of Florida sites and planting success
will be evaluated. Mangroves of a variety of sizes were planted at
sites that differed in energy, tidal depth, root-parasite prevalence,
substrate, salinity and public access. Measurements made after varying
period indicated that energy, tidal depth and vandalism were the most
important limiting factors for survival and growth. Planting costs
were estimated by collecting and planting experience of our own group
from $452 per acre for red mangroves at 3 ft centers to $87,500 for 3
year-old trees at 4 foot centers.
