Ideally, evaluation of habitat modification and restoration projects would include pre- and post-construction data. Given
that many projects have not typically included any pre-construction information, and post-construction data is relatively
sparse, can an assessment be made of the success of the project. In order to understand the link between the physical
structure and biological response I borrowed published data from Index of Biotic Integrity studies. I test the correlation
between species richness, key indicator species abundance, and overall community biomass with habitat variables, controlling
for watershed position. If habitat condition can adequately predict the in-stream biotic community, this would greatly
simplify the task of monitoring the success stream modification projects.
