In almost all estuaries the salinity of the water changes constantly over the tidal cycle. To survive in these conditions, plants and animals living in estuaries must be able to respond quickly to drastic changes in salinity. Plants and animals that can tolerate only slight changes in salinity are called stenohaline (Sumich, 1996). These organisms usually live in either freshwater or saltwater environments.
Costs for chain link fences range from around $7 to $12 a linear foot for a 4-foot high fence, making a 200 linear foot fence cost roughly $1,400 to $2,400 in materials. Costs can vary depending on whether or not the fence is vinyl 1 coated and for taller fences, as well as for heavier wire.
1 With professional installation, a typical residential chain-link fence can cost $5-$35 or more a foot for labor and materials, depending on height, type (galvanized or vinyl color coated), gauge and mesh size, or about $600-$4,000 for 100' and $2,000-$11,000 for 300' of fencing. Production Fence Works in Georgia estimates average costs with professional installation at $7.99 per foot for a 4' high residential galvanized chain-link fence and $8.99 a foot for 6' high, with a gate adding $130-$320.
