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.
According to the home improvement project website DIY Or Not, the average price for a contractor to build a 100-foot long, 4-foot-high chain link fence reaches about $800 as of January 2011. In contrast, a property owner who chooses to do the work himself can build a similar fence for around $590. The pricing website Cost Helper goes on to explain that a 300-foot fence with a pair of gates typically costs between $1,800 and $2,500 in materials and can cost as much as $3,300 installed, as of January 2011.
