The NASA Ecological Conservation Program works with organizations interested in using remotely sensed satellite data to make decisions regarding conservation of natural resources. These organizations are using remotely sensed data to better understand the current status of important natural ecosystems such as coral reefs, coastal estuaries, prairie grasslands, freshwater floodplains and many other natural systems. Forecasts of expected changes in ecosystems also help resources managers to plan for and mitigate adverse changes that may affect ecosystems function as habitat for native plant and animal species. Expected outcomes are to preserve natural ecosystems and native species for the benefit of future generations. Natural ecosystems help to filter pollutants, are important for eco-tourism, and recreational hunting and fishing.
