Description:
Abstract:
This data represents areas of forest damage due to insect infestation, fire, flood, landslides, and windthrow. The information was collected, cooperatively by aerial surveys by both the USFS, Forest Health Protection (FHP) and ADNR, Div. of Forestry. 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 such that the maximum extent of recent bark beetle damage (fading trees) and insect defoliation (discoloration, foliage loss) patterns may be determined. Surveys are flown in Southeast Alaska, Southcentral Alaska and Interior Alaska. The data represents a 10 year cumulative effect for 1989-2010.
Purpose:
This data is collected to monitor forest health for the State of Alaska (FS- R10) and to identify insect and some disease pest trends. Accuracy and repeatability can not be duplicated due to the nature of aerial survey data collection. This data should be used as an initial identification of pest areas or landscape level planning but further surveys or ground truthing is necessary for area planning or management. More specific delineation of pest damage boundaries (polygons) may be obtained by later ground assessments or approximation of several individual years of mapping data. Precise timing of the surveys for maximum symptom development is not always possible so that the aerial extent of damage generally cannot be accurately mapped for all pests. Also, many pest symptoms are delayed from the time of actual damage so that visual symptoms do not appear for several months after the initial damage. In the case of some bark beetle damage, (e.g., spruce beetle) symptoms of "red-topped" or "fading red" trees do not show until the season after initial attack. Precise estimates of the extent of bark beetle damage often required a corroborative ground assessment to determine the extent of current season attacks. Also, some defoliator damage is not readily apparent from the air or occurs outside of the aerial survey window of time so that the actual extent (acreage) of damage cannot be accurately determined without extensive ground sampling

Data_Quality_Information:
Attribute_Accuracy:
Attribute_Accuracy_Report:
Attribute accuracy is tested by visually comparing the source with hard copy printouts or interactive display of forest damage data on a computer. Frequency tables also verified standard coding.
Logical_Consistency_Report:
No overlaping polygons are present. Polygons crossing quadrangle boundaries were edge matched.
Completeness_Report:
Surveys in Alaska are meandering surveys predominantly following drainages and shorelines. Approximately 1/4 of the state is surveyed each year. The flightline file represents the flight path. The extent of visibility is roughly 2 miles.
Positional_Accuracy:
Horizontal_Positional_Accuracy:
Horizontal_Positional_Accuracy_Report:
Digital information collected using GPS for tracking and polygon placement accuracy. Polygons are sketched onto a computer screen or paper maps (USGS 1:250,000 hardcopy or digital maps).
Quantitative_Horizontal_Positional_Accuracy_Assessment:

Process_Description:
Surveys were conducted by USFS State and Private Forestry personnel in cooperation with Alaska Department of Natural Resorces. The data is recorded at the time of capture on 1:250,000 scale USGS topographic-bathymetric series maps. Data on all surveys is collected from a fixed wing platform at 500 - 2000 ft. above ground level (AGL). Data collected at time of capture. Transformed into ArcGIS 9.0 for editing and correction. Multiple data sets were merged and projected to Albers equal area (AK), NAD83. Point data was buffered 75 meters and merged with polygon layer. Multipart polygons were converted to single part. Overlapping polygons were dissected.

Overview_Description:
Entity_and_Attribute_Overview:
Areas of damage are delineated on the base maps as polygons and labeled with an agent code and for some insects a severity code. Inherent in many agent codes is the host species. The first three letters of each polygon label identify the damage, causal agent, and host species. The fourth letter, if present, identifies severity. Acres for each polygon are rounded for display. Mortality agents/damage are also attributed with an estimate of the number of trees killed or a trees per acre killed. Trees per acre are reported since 2001.
