Wetlands are the most productive ecosystems on the planet. In the coming decades, wetland protection must become a priority before all wetland areas are destroyed. In a world where cost and economic profit dominate decisions, it is imperative to assign monetary worth and value to environmental systems. This economic assessment of the ecosystems can be then more easily be compared to other regions to ensure that the public is aware of its many values at the local, regional, and global scale.
Jamaica Bay provides a myriad of ecosystem services and one of particular interest is the measurement of carbon storage. The purpose of the project is to measure and compare the amount of carbon sequestered in four marshes of Jamaica Bay: Big Egg, Four Sparrow, Yellow Bar, and Joco. These values can be converted to monetary estimations and in conjunction with the other economic models, a total value can be developed for the park.
Big Egg
Method that indicates the amount of organic matter (weight lost after burning) and inorganic matter (remaining mass after burning) in a sample.A sample of a core is weighed and dried at 100ºC, then burned at 375ºC and weighed again. Weights are recorded and used for mathematical analysis.

Results:
Valuation is an important tool that can be used to place a ‘value’ on a specific ecosystem or area.
Individual values are specific to certain ecosystem services that are particular to certain landscapes and environments. Ecosystem goods and services are the benefits we receive from nature. They are important to human health and sustenance (EPA).
Some examples of services provided by Jamaica Bay are:
Migratory bird habitat• Flood Protection Recreation• Fish and Wildlife Habitat• Carbon Storage
There are several economic models that are applicable to ecosystem services such as: Market Price Valuation, Travel Cost Method, Benefit Transfer Method and Damage Avoided/Replacement Cost Method.
Further analysis and monetary values will be developed when proper data is acquired in the future.
