The Human Ecology Mapping Project is a multi-year study to understand and map human activities and values in the forests of Washington's Olympic Peninsula. Using a web-based mapping tool and a series of community workshops, the project identified and displayed the diversity of recreation, cultural, historical, and economic connections held by a variety of agencies, tribes, resource users, and residents. The maps were digitized and analyzed using GIS tools to reveal existing patterns, such as high intensity sites, areas of overlapping use, and treasured places with barriers to access. These sociocultural data layers can be integrated with biophysical data layers for use in planning. By understanding changing patterns of resource use and human activity area-wide, national forest planners can make informed decisions about their own management unit.
