Description

This model combines stand density index (SDI), basal area loss, drought stress, and insect and disease surveys using an equal weight overlay. SDI determines the relative density of a stand, and was used in this model to identify where the density of small diameter trees is high. Basal area loss is defined as "the expectation that, without remediation, 25 percent or more of the standing live basal area of trees greater than 1 inch in diameter will die over the next 15 years (starting in 2005)." For the purposes of the New Mexico State Assessment, the basal area loss data layer represents areas of dense forest/woodlands with large diameter trees expected to experience mortality from insect and disease. SDI and basal area loss data layers were derived as a part of the 2006 National Insect and Disease Risk Map (NIDRM) and based on New Mexico's Forest Inventory Analysis Data from 1987-1999. Moisture stress depicts percent of normal precipitation for winter precipitation from 2006-2008 and was derived from PRISM precipitation data. Insect and disease outbreaks data was limited to past occurrence flyover data for western spruce budwrom and western tent catepillar and are based on USFS Forest Health Aerial Survey data from 1987-2008 .
