Long Island Mammal Distribution Maps

Data collected through the mammal survey, after being reviewed and approved, is being carefully compiled in geographic image system (GIS) maps. Each of the twenty-seven target species has its own map, which details the extent of its range on Long Island.

The distribution maps are based on an overlay grid that divides Long Island into a series of squares, each of which includes an area of nine square miles.

The status of a species’ status in each square on the grid is identified in one of three following ways:

GREEN = confirmed observations

CLEAR = no observations
