Agricultural Field Percentage by Town in 1985

Percent Ag Field in 1985 Percent Ag Field Legend
The area of each municipality was divided by the area of the Agricultural Field class to determine the percent of Agricultural Field. This map is intended to be used with the Agricultural Field Percentage by Town in 2006 map.

The area of each municipality was divided by the area of the Agricultural Field class to determine the percent Agricultural Field. This map in intended to be used with the Agricultural Field Percentage by town in 1985 map.

Percent Ag Field Legend

The area (in acres) of Agricultural Field for each municipality in 1985 was compared to the area (in acres) of Agricultural Field for each municipality in 2006. The municipalities are then colored based on the change, in acres, according to the legend (above).

Note that there is a bias to the larger towns that have more acres.

Relative Percent Change in Agricultural Field 1985 to 2006

Percent Change in Ag Field

 

  -100% to -54%
  -53% to -30%
  -29% to -15%
  -14% to 0%
  +1% to +88%

The relative percent change was determined by subtracting the 1985 Agricultural Field area from the 2006 Agricultural Field area and dividing the difference by the 1985 Agricultural Field area. This shows how quickly land cover is changing relative to the 1985 baseline.

(2006 area - 1985 area)/1985 area

Note that there is a bias towards towns with less Agricultural Field where a small loss of Agricultural Field can result in a large percentage
