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.
Recent estimates on materials used to construct chain link fence is as follows: Plain silver galvanized steel 3 foot high fence is $75 to $100 per 50 foot roll. At six feet high the same gauge fence is $150 to $200 per 50 foot roll, and at 12 feet it is $350 to $400 for a 50 foot roll.
