Boston Harbor

Winter TASL census regions

These divisions of the Harbor were established in 1980 and the route used for each census region has been roughly the same over the years. Currently 11 parties cover the seven regions. Each census lasts approximately three to four hours.

In order to achieve maximum reliability in counts we have tried to keep the same censusers working the same routes over the years. We also try to schedule the censuses to coincide with rising or high tides.
