Tidal Crossing Handbook, A Volunteer Guide to Assessing Tidal Restrictions. Timothy A. Purinton, David C. Mountain. 69 pp.

The Parker River Clean Water Association (PRCWA) is an independent, non-profit organization dedicated to promoting the restoration and protection of the ecological integrity of the Parker River, Plum Island Sound, their tributary streams, and adjacent lands. The Parker River-Plum Island Sound Basin covers 82 square miles in northeastern Massachusetts and contains extensive salt marshes. This handbook is designed to disseminate the methods of assessing potential tidal restrictions that were developed by the PRCWA to other volunteer-based efforts along the coast of the Gulf of Maine and elsewhere. This resource has five chapters: (1) the salt marsh: a place to value and protect, (2) getting started, (3) phase 1: visual assessment, (4) phase 2: measuring the tides, and (5) phase 3: taking action. The handbook also has two appendices, one goes over troubleshooting, the other provides some example data sheets for the field.
