Smaller and smaller forests

  Humans are cutting Colorado and Wyoming forest into an increasing number of isolated stands that threaten forest health, according to three new videos highlighting a conference devoted to forest fragmentation in the central Rocky Mountains. "Everybody who lives in these states has an opinion about forested public land, but most impressions seem to be based on gut feelings rather than knowledge," says wildlife biologist Rick Knight, who introduces the videos. The first half-hour video covers human disturbances, such as logging, road building and residential development; the second covers natural damage including fire, disease, and wind storms like the one last winter that leveled 20,000 acres of Routt National Forest (HCN, 11/24/97). The third attempts to explain the effects of forest fragmentation on plant and animal diversity. Each "Forest Fragmentation" videotape costs $10 from the Office of Instructional Services, Colorado State University, A71 Clark Bldg., Fort Collins, CO 80523 (970/491-1325).
