What's happening on the lands maintained by the United States Forest Service? Those parties with a vested interest in such matters will want to stay abreast of the Forest Service's Schedule of Proposed Actions (SOPA). These documents are published in January, April, July, and October and contain a list of "proposed actions that will soon begin or are currently undergoing environmental analysis and documentation." Each SOPA contains information about proposed projects that will take place within Forest Service properties, and as they can be complex documents, visitors should also look at the "How to read the SOPA" section. Visitors can use the drop-down menu on the site to view the SOPA for a particular National Forest, Grassland, Scenic Area, Recreation Area, or Tallgrass Prairie. The site is rounded out by a list of abbreviations and definitions and links to other relevant publications.
