Core sampling is a highly accurate resource assessment tool. Use it to conduct shellfish surveys and to determine the effectiveness of management activities.
This method is more exact than using a clam hoe to survey because it takes the same surface area and volume with each sample. It also allows you to take a random, uniform, and undisturbed section of the mudflat to examine. Rinse the sample in a sieve to measure the number and size of clams and other species in the intertidal as part of population survey or other study.
