The Rocky Mountain Forest and Range Experiment Station, Ft. Collins, Colorado, has 4 more RPA assessment papers for distribution. (1) General Technical Report RM-241, "Species endangerment patterns in the United States" by Flather, Joyce and Bloomgarden. 1994. 42 p. The single-species approach to conserving threatened and endangered species in the United States is insufficient, given the number of species (more than 700) officially considered at risk of extinction (i.e., formally listed under the Endangered Species Act of 1973), the rate at which new species are being listed (more than 50 species a year), and the number of species awaiting listing (more than 3,500 candidate species). Regions supporting many endangered species were located in the humid Southeast and the arid Southwest, and tended to be unique with respect to taxonomic composition, prevalence of endemism, climate, land-type associations, and factors contributing to species endangement. (2) General Technical Report RM-242, "Recycling and long-range timber outlook" by Ince. 1994. 23 p. This report provides analysis of long-range trends in paper recycling and impacts on the timber outlook for the 1993 RPA Assessment Update. Paper recycling is projected to increase substantially in the next decade, followed by more gradual increases in subsequent decades. Increased recycling will extend timber resources and fiber supply. (3) General Technical Report RM-244. "Biological diversity: Status and trends in the United States" by Langner and Flather. 1994. 24 p. Biological diversity in the United States is summarized in three categories: genetic diversity, species diversity, and community/ecosystem diversity. Major changes have occurred in the distribution and abundance of native diversity, in the United States, in the past 300 years. Native plant and animal diversity has declined over the past three decades, and is likely to continue to decline because of continuing human population growth and associated development. (4) General Technical Report RM-248. "Effect of management on water quality in North American forests" by Brown and Binkley. 1994. 27 p. Although the quality of water draining forested watersheds is typically the best in the Nation, some forest management practices can seriously impair streamwater quality. Sediment is the main concern. High suspended sediment levels, and adverse changes in stream channels, are potential problems in several regions, especially after road construction, and some harvesting and grazing practices. Impacts are most serious where fish reproduction is affected. Nitrate and water temperature are less serious problems. Harvesting can increase nitrate levels markedly, in some locations; and removal of overstory from along streambanks can raise water temperatures enough to impair fish survival. Best management practices (BMPs) can avoid most of these harmful effects. Additional work is needed, in some locations, to encourage BMP use and to tailor BMP specifications to site-specific conditions. To order any or all 4 of these publications, give me the General Technical Report numbers and DG R.Schneider:S28A or E-mail:fswa/s=r.schneider/ou=s28a@mhs.attmail.com with your name and complete mailing address in block format (type as if you're addressing an envelope, so I can cut out the address, thereby saving me having to type labels.)
