“…This contrasts both with the literature on general environmental monitoring (e.g. Messer et al, 1991;Wiersma et al, 1984Wiersma et al, , 1991Wiersma and Otis, 1986;Hicks and Brydges, 1994;Stevens 1994) and, more markedly, with the large literature on the evaluation of sites for nature conservation. Much of this latter literature has been reviewed by Margules and Usher (1981) and Spellerberg (1992).…”

A great deal of attention has been paid to the selection of nature reserves. These are important from a conservation viewpoint but, for long-term evaluations, it is important to monitor ecosystems. The need for long-term monitoring plots has been recognized for some time in forest ecology. Of the natural ecosystems, forests are some of the most difficult to monitor because of the time-scales involved in the life-spans of the dominant organisms (100 → 1000 years). The selection of long-term forest ecosystem monitoring plots is a critical process involving decisions that need to remain valid for many years. Traditional sampling theory suggests that some form of systematic or random sampling may be appropriate, but this is usually inappropriate for the selection of ecosystem monitoring plots. Instead, the selection of plots more closely resembles some of the procedures that are used in the selection of nature reserves. In Switzerland, a monitoring programme has been established which uses a number of criteria for the selection of sites. These include site homogeneity, the abundance and sensitivity of the plant communities to change and the presence of pre-existing data series or monitoring equipment. In addition, the human factor is incorporated by selecting sites from throughout the country, with the willingness of the local forest managers to help with the project being an important factor influencing the final choice of plots. In contrast to most inventories, statistical representativeness is not a requirement for the programme, as the plots are treated as a series of case studies.

“…This allows one to view the monitoring problem as one of contaminant sources and pathways to critical receptor components of the ecosystem. For example, certain contaminants (e.g., lead) may be expected to reach high levels of accumulation in forest litter (e.g., Wiersma and Otis, 1986). …”

“…The monitoring approach presented in this Manual is based on multimedia monitoring and an ecosystem approach derived from numerous years of monitoring and research experience at areas including U.S. National Parks, Biosphere Reserves (e.g., Wiersma et al, 1984Wiersma et al, , 1985; Wiersma and Otis, 1986), and U.S. wilderness areas (e.g., Bruns et al, 1982Bruns et al, , 1984.…”
