We developed a methodology to analyze the effects of management practices on landscape structure and function to be used in the assessment of sustainability in intensively managed forest landscapes. It is based
on modeling and simulation of landscape and stand structure as well as biological and physical processes. The
methodology includes a landscape structure model and several forest stand-level models to simulate the
dynamics of landscapes and stands as a function of management rules. It also includes habitat models to evaluate
landscape quality and spatial characteristics of vertebrate habitat, and a hydrologic model to simulate water and
sediment yield at the subarea and watershed levels. The application of this methodology to the Sustainable
Forestry Initiative (SFI) program in eastern Texas indicated that this is an effective way to evaluate effects of
sustainable forestry programs on landscape structure and processes. During simulation years, the habitat of pine
warbler, the species used as an example to illustrate the methodology, became apparently fragmented under the
SFI scenario. This fragmentation was caused mainly by narrow, forested streamside management zones
dissecting pine stands and should have little negative influence on the pine warbler habitat. Sediment yield at the
landscape level decreased by the implementation of SFI measures, particularly by the reduction of channel
degradation.
