Many agencies had in-house scientific expertise, and those scientists had the normal relationships with their peers in universities, think tanks, and consulting companies that one would expect to see anywhere. But those agencies often had relatively little experience in funding outside scientists, especially using competitively awarded, peerreviewed grants. Others had primarily in-house science management expertise, and were oriented primarily towards the award of grants to outside scientists. Still others, including EPA at the time, had a mixture of each, but had not often made an institutional commitment to one mode of operation or another.

4. 2. S. Department of Agriculture Forest Service in the White Mountains of New Hampshire to investigate the structure and function of forest and aquatic ecosystems, and their response to disturbance (Likens and Bormann 1995; Groffman et al. 2004). Hubbard Brook was the site where acidic deposition was first reported in North America (Likens et al. 1972). Hubbard Brook receives elevated inputs of acidic deposition and the forest ecosystem is very sensitive to these inputs. There have been long-term measurements and studies of acidic deposition and its effects on forests and streams at Hubbard Brook (Likens et al.

For example, one might speculate that hardwood species such as white ash and basswood that prefer rich sites high in nutrient cations may experience problems in areas where nutrient cations have been depleted by acidic deposition. However, additional research is needed to assess more fully the response of these tree species to acidic deposition. 3. 3); and increasing dissolved inorganic aluminum concentrations. While sulfate concentrations in lakes and streams have decreased over the last 20 years, they remain high compared to background conditions (< 20 jiieq/L; Sullivan 1991).
