This study involved collaboration between natural resource scientists and economists to develop strategies for identifying ecologically significant habitat patches on the watershed scale and for prioritizing those patches for targeted conservation efforts. In phase 1 of the study, ecological models of the breeding effort for two amphibian species (Rana sylvatica and Ambystoma maculatum) were developed using available landscape data, and these models were used to estimate breeding effort for all known vernal pools within an entire watershed area.

This data, combined with land cost estimates for the watershed, could then be used to rank individual one-hectare parcels for conservation importance. Phase 2 of the project will move beyond discrete one-hectare habitat patches and will take into account ecological processes and resulting spatial linkages that may influence the long-term sustainability of biological diversity in the conservation reserves.
