Occupancy 1990-2020

The map shows differences in the species breeding distribution between the 1980's breeding map and the current weighted breeding evaluation. Negative value - species previously bred in the grid and is not presently breeding; positive value - species has not previously bred in the grid and is currently breeding.

Change in Relative Abundance 1990-2020

The map shows the changes in the relative abundance of a species in each of the distribution grids between the breeding map of the 1980s and the weighted current breeding evaluation. Negative values - decline in abundance; positive values - increase in abundance; zero - no change in abundance.
