The HCP includes an extensive research and monitoring program to assess the effectiveness of HCP activities. Evaluating the effectiveness of HCP actions is especially important because of the long-term (50-years) nature of the HCP. To measure our progress a set of assessment metrics have been identified that represent specific measurable aspects of species and habitats addressed in the HCP. By documenting the work we perform under the HCP, we can track compliance with our legal commitments and use the information to interpret these metrics of effectiveness.

In addition, a large number of research projects conducted under the HCP have resulted in publications (pdf) in peer-reviewed journals.
