Priority Square Maps

While the MBA will accept records from anywhere in the Maritimes, atlassers are encouraged to adopt their own priority square. This will help provide an even distribution of observations across the Maritimes.

If you adopt a priority square you are encouraged to visit a variety of habitat types in the square. Locations with good potential include wetlands and bogs, o


vergrown fields, flower gardens, woodland clearings, wide woods roads or trails, and recreation paths. You are also encouraged to visit the site multiple times (every few weeks or so) from spring to fall. Visiting a variety of habitats at a variety of times during the course of the year is the best way to encounter the most diversity in a square. Remember that the Atlas is a five year period. If you miss a visit in August this year you can always visit the square August next year.

For the purposes of the Atlas, the Maritimes is split into 27 regions. Click here to view the 27 regions of the Maritimes.

Once you have identified the region you are interested in surveying, click on the link below to the more detailed regional maps below for locations of the priority squares. If you find a priority square that is of interest to you contact John Klymko ( to sign up for it.
