I imported SHP files from the Michigan.gov/CGI website which included land cover information for a county. In just one imported layer I have wooded wetlands, shrubs, water mass, lowland hardwood, Aquatic Bed Wetland, and Emergent Wetland. Can I split this layer and create new layers for each of these groups of information? I have filtered the information I want to seperate, but I'm having difficulty creating the new layers. Where do i need to look?
