Ecosystem administration calls for a making plans and decision-making strategy that locations land use in its applicable ecological context. simply because ecological exams has to be carried out at numerous spatial scales and throughout jurisdictional limitations, ways to evaluation has to be suitable and in step with one another. A Guidebook for built-in EcologicalAssessment analyzes equipment and offers criteria and protocols for overview and the combination of data.

Landscapes exhibit spatial pattern and internal heterogeneity. It is this heterogeneity that is of interest. The continuity of the landscape suggests that it also has boundaries where landscape elements come together. , 1985; Forman and Moore, 1992; Vos and Opdam, 1993; Forman, 1995). Boundaries, natural and anthropogenic, are very important in designing research and monitoring for ecological assessment. Second, landscapes also have function. That is, there are interactions among spatial elements.

How often will we measure a dynamic process? How will we analyze the data? These considerations again must be tied directly to the question addressed by the assessment and the levels in the system appropriate to the question. 2 Ecosystems as Hierarchies glean from the data. Do not expect the measurement of microbes to capture the dynamics of a whale. Costanza and Maxwell (1994) used information theory to investigate the effect of spatial resolution (grain) on aspects of predictability. , land cover class).

Strategies of landscape design directed toward desired ecological condition objectives for management are best framed within a multiscale ecological assessment process. In this approach, desired ecological conditions are defined at different scales dependent on the specific issues at hand. Design objectives identified at broader scales are incorporated into management strategies for smaller ecosystems to ensure that activities at more localized levels are consistent with the larger plan. Multiscale ecological assessments enable decisions to be made from scale-appropriate information, and they place allocation and regulation decisions into the proper biophysical and social context, hence contributing to improved management decisions.
