![]() The 2006 National Insect and Disease Risk Map (NIDRM) Project integrates 188 individual risk models constructed within a common, consistent framework that accounts for regional variations in current and future forest health. The 2006 risk assessment, conducted within the contiguous United States and Alaska, provides a consistent, repeatable, transparent process through which interactive spatial and temporal risk assessments can be conducted at various scales to aid in the allocation of resources for forest health management. This modeling process is intended to increase the utilization of forest health risk maps within and outside the National Forest System and encourage development of future risk maps. NIDRM...
![]() This data represents areas of forest damage due to insect infestation, fire, flood, landslides, windthrow and other mortalities. The information was collected by aerial surveys by both the USFS and ADNR, Div. of Forestry in cooperation with the Forest Health Protection (FHP) project. Surveys are conducted in July and August so that pest "signatures" may be obtained during the optimal period for symptom development of ocular estimation. The aerial survey is coordinated with known pest outbreaks so that the maximum extent of recent bark beetle damage (fading trees) and insect defoliation (discoloration, foliage loss) patterns may be determined. Aerial survey flights are termed as "local" if they can be completed...

The information was collected by aerial surveys by both the USFS and ADNR, Div. of Forestry in cooperation with the Forest Health Protection (FHP) project. Surveys are conducted primarily in July and August so that pest signatures may be identified during the optimal period for symptom development of ocular estimation. The aerial survey is coordinated with known pest outbreaks so that the maximum extent of recent bark beetle damage (fading trees) and insect defoliation (discoloration, foliage loss) patterns may be determined. Aerial survey flights are termed as local if they can be completed within 1 day...
This dataset was developed for the BLM-Rapid Ecoregional Assessment (REA) project for the Seward Peninsula - Nulato Hills - Kotzebue Sound Lowlands. This datasets represents the Change Agent, pests and disease, specifically identifiying beetle infestations. The information was collected, cooperatively by aerial surveys by both the USFS, Forest Health Protection (FHP) and ADNR, Div. of Forestry with beetle data clipped to the REA project boundary. The data represents a 10 year cumulative effect for 1989-2010.

2010 USDA Forest Service, Rocky Mountain Region Aerial Detection Survey Data. This data depicts the occurrence and location of forest insect, disease, and other biotic and abiotic causes of tree mortality and tree damage. Aerial survey data is collected by observing areas of tree damage or tree mortality from an aircraft and manually recording the information onto a map. Due to the nature of aerial surveys, this data will only provide rough estimates of location, intensity and the resulting trend information for agents detectable from the air. Many of the most destructive diseases are not represented in the data because these agents are not detectable from aerial surveys. The data presented should only be used as...

Climate Change and Bark Beetles of the Western United States and Canada: Direct and Indirect Effects
Climatic changes are predicted to significantly affect the frequency and severity of disturbances that shape forest ecosystems. We provide a synthesis of climate change effects on native bark beetles, important mortality agents of conifers in western North America. Because of differences in temperature-dependent life-history strategies, including cold-induced mortality and developmental timing, responses to warming will differ among and within bark beetle species. The success of bark beetle populations will also be influenced indirectly by the effects of climate on community associates and host-tree vigor, although little information is available to quantify these relationships. We used available population models...
