Northern_Rockies_fire_extent_ha.csv

Description

Northern_Rockies_fire_extent_ha.csv contains a time series of annual fire extent in hectares from 12 national forests and 1 national park in Idaho and Montana west of the Continental Divide. In addition to total fire extent, it includes fire extent by vegetation type (environmental site potential, ESP). The column headings are self explanatory (year,total_fire_extent_ha,cold_forest_extent_ha,mesic forest_extent_ha,dry forest_extent_ha,woodland_extent_ha,mesic shrub_extent_ha,dry_shrub_extent_ha,grassland_extent_ha,other_extent_ha,sum_of_extent_by_ESP). total_fire_extent_ha is not exactly equal to sum_of_extent_by_ESP because the values by ESP were computed within the fire-atlas recording area only whereas a small percentage of total fire extent occurred outside the fire-atlas recording area.

Checksum values for the columns are:

total_fire_extent_ha	5,117,373
cold_forest_extent_ha	1,706,807
mesic forest_extent_ha	637,177
dry forest_extent_ha	1,757,420
woodland_extent_ha	257,232
mesic shrub_extent_ha	324,886
dry shrub_extent_ha	282,531
grassland_extent_ha	36,685
other_extent_ha	106,350
sum_of_extent_by_ESP	5,109,089
