Effective. Professional. Experienced.

Zentner Planning and Ecology was retained by the Port Sonoma Marina to conduct protocol-level surveys for the California Clapper Rail (CCR, Rallus longirostris obsoletus), a Federal and State-listed endangered species. Surveys were completed to determine whether CCRs occupied the unused eastern end of the Port, which had developed an expanse of tidal marsh. We completed surveys at the Port and in the nearby tidal marshes to ensure CCR counts were being completed accurately. Successive surveys then demonstrated conclusively that CCRs were not in the Port habitats.
