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 Chain-link fence prices change when the cost of steel fluctuates. 2  Generally, materials for a typical residential chain link fence (2 mesh, 9 or 11 gauge) might cost $3-$6 a linear foot for 4' high or $8-$15 a foot for 6' high, depending on whether it's galvanized or vinyl coated. For example, Production Fence Works in Georgia estimates average cost for an 8' high, 60'x100' fence around a single tennis court with a single walk-in gate at $9,200. 2  Because of its open weave, a chain-link fence is transparent. 3  To make it more opaque, metal, wood or vinyl privacy slats can be woven into the mesh.
