To effectively and systematically survey the entire Vermont landscape, we have used a gridding system to divide the state into roughly 3 x 3 mile blocks. These blocks are based on the U.S. Geological Survey 1:24,000 topographic maps (“7½-minute maps”), each broken into 6 equal squares, creating 1,180 blocks statewide.
Using Vermont's Agriculture Land Cover 2016 dataset, the hayfields and pasture over 10 hectares within each block was summed to determine which blocks contained the most suitable Eastern Meadowlark breeding habitat. Because of Eastern Meadowlark's specific habitat needs, these are the blocks most likely to host breeding populations or territorial individuals, and where surveys should be focused.
