Description:

The data give the ant species richness (number of ant species) found in 64 square metre sampling grids, in 22 bogs and 22 forests surrounding the bogs, in Connecticut, Massachsetts and Vermont (USA). The sites span a 3° of latitude in New England.

There are 44 observations on four variables, plus the site identifier.

Variables:
Site An abbreviation for teh name of the site
Srich The species richness (number of species) for ants
Habitat Either Forest or Bog
Latitude The latitude (in decimal degrees) for the site
Elevation The elevation of the site, in metres above sea level
