Parent Layer: Hawaii

Name: Loss, % of Hawaii Hosts

Display Field: VALUE

Type: Raster Layer

Geometry Type: null

Description: This raster dataset shows the average projected loss rate across all four forest pests modeled in Hawaii, 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. ______________________ NOTE: Due to lack of FIA plot data, NIDRM only modeled tree host extent in Hawaii and did not estimate tree species basal area (BA) as was done in the rest of the United States. This raster integrates the impacts from the four forest pests in Hawaii. In cases where multiple pest/host combinations have projected losses on the same pixel, this grid is the mean average of all individual host loss rates on that cell. For Hawaii, the NIDRM project did not have modeled estimates of individual tree host basal area, and therfore, could not estimate the proportion of total basal area comprised by the four modeled tree species hosts. For Hawaii, this composite loss rate raster dataset should not be interpreted as a proportion of total basal area loss.
