pollution, food web changes and accelerated sedimentation. These phenomena can <br />be used as benchmarks that integrate the environmental health of the catchment if the <br />data are gathered systematically over long periods. Analysis of trends in such data can <br />reveal how leaky or unconnected the system may be and provide clear insights where <br />management actions can be effective in reconnecting the system. This effort can best <br />be accommodated by insightful, integrated management. <br />Literature Cited <br />Alstad, D. N. 1982.
