This raster dataset shows the projected basal area loss due to all forest pests and pathogen activity, assuming no remediating management, over the 2013-2027 time frame.
The 2012 National Insect and Disease Risk Map (NIDRM) Project integrates 186 individual risk models constructed within a common, consistent framework that accounts for regional variations in forest health conditions. These 186 models are built to portray the expected loss of host basal area for each pair of damage agents and hosts over each unique landscape where they coexist.
This dataset composites the projected BA loss for XX by tree species host model and then divides the total BA losses from XX by total basal area. |
