Ecosystem Management Decision Support is a way of helping people make decisions about the environment. It does this by giving people rules and information about the environment so they can make the best choices for their area. For example, an ecosystem management decision support system might tell you what kind of plants and animals live in a particular area and what type of activities are allowed in that area, so you know how to treat the land and encourage healthy habitats for animals. This helps people decide how to keep the environment healthy and how best to use the land.
