Description:
Abstract:
The Establishment Potential Surface for Ips typographus was produced for the State of Alaska in 1 square kilometer (km²) units by the U.S. Forest Service (USFS), Forest Health Technology Enterprise Team’s (FHTET) Invasive Species Program. Supporting information for this product was taken from Exotic Forest Pest (ExFor) website (
Purpose:
The product’s intended use in conjunction with the Introduction Potential Surface is to develop a Susceptibility Potential Surface for Ips typographusin the State of Alaska.Three primary datasets with standardized values from 0 to 10 were used in the analysis. Two primary data sets are: 1) Disturbance, and 2) Host. The output values also range from 0 to 10 with 10 having the highest establishment potential. Establishment potential surface is related to disturbance (Gilbert 2005). The Disturbance data consists ofthree data sets: 1)Forest Damage factors from 1989 - 2005(Table 3), 2) Fires from 1950 –2005, and 3) Flooding. Host data consists of: Forest cover types that contain one or more of the following tree species:Spruce, Larch, and Fir (Table 4). Host and Disturbance data were combined into a weighted overlay illustrated in Table 5 to produce the final Establishment surface.
Data from Fires(2000 – 2005)were collected and labeled as Recentdisturbance data. The Forest Damage, Fires (Fires from 1950 – 1999) and Flooding were combined via a maximum overlay process and labeled as Historic disturbance data. The RecentDisturbance and Historic Disturbance data were combined using an equal weighted overlay process to produce the final Disturbance surface.
Supplemental information:
Disturbance
The Disturbance surface consists of three data sets: 1) Forest Damage, 2) Fires, and 3) Flooding. Further, the Disturbance surface is partitioned into two surfaces: 1) Historic Disturbance, and 2) Recent Disturbance.
Forest Damage
Forest Damage types used for the construction of this model are contained in Table 3. Two Forest damage data sets were used: 1) Forest Damage from 1989 – 2002 (Appendix B), and 2) Forest Damage from 1996 – 2005 (Appendix C). These data were combined into a single forest damage data set using types contained in Table 3 then repartitioned. Since these Forest Damage data have a temporal overlap; therefore, we needed to edit the data to remove the temporal overlap. Then, the Forest Damage data were combined into one data set for the time period from 1989 to 2005 then partitioned using a temporal scale as follows: Forest Damage 1989 – 1995 and Forest Damage 1996 – 2005. Both of these data sets were converted to 1000 X 1000 meter GRID Cells. That is, where forest damage occurred a GRID value of 10 was assigned to that cell.

Fires
See Appendix D for Metadata on these data. Two Fire data sets were used: 1) Historic Fires from 1950 – 1999, and 2) Recent Fires from 2000 – 2005. Both fire data sets were converted into 1000 X 1000 meter GRID cells with a constant value of 10 for all areas where fires occurred.
Historic Fires
Consist of Fires from 1950 – 1999 (Appendix D). This fire data set was converted into 1000 X 1000 meter GRID cells with a constant value of 10 for all areas where fires occurred from 1950 - 1999.
Recent Fires
Fires from 2000 – 2005 (Appendix D). This fire data set was converted into 1000 X 1000 meter GRID cells with a constant value of 10 for all areas where fires occurred from 2000 - 2005.
Flooding
Data for flooding was acquired from FHTET in Fort Collins, Colorado in the Risk Mapping Program. Data for flooding wassplit into three basic classes as follows: 10 = high flooding potential, 5 = Moderate flooding potential, and 0 = Little or No Flooding potential.
Historic Disturbance
Using a maximum overlay process we combined Historic Fires (Fires from 1950 – 1999), Forest Damage 1989 – 1995, and floodinginto a single Historic Disturbance Data Set. That is, anywhere a fire, a forest damage event, or a floodoccurred that particular GRID cell coincident with that event would have a GRID value of 10.
Recent Disturbance
Recent Disturbance uses Recent Fires (from 2000 – 2005) and Forest Damage 1996 – 2005 This Fire data set and the Forest Damage data set were converted into 1000 X 1000 meter GRID cells with a constant value of 10 for all areas where Fires or Forest damage occurred during each data sets respective time periods.
The final Disturbance surface is the result of an equal weighted overlay of Historic Disturbance and Recent Disturbance.
Host
Host Species: (Appendix A). Forest cover types that contained one or more of the following tree species: Spruce, Larch, and Fir (Table 4) were used. Pure spruce (Picea sp.) forests are considered the preferred host; therefore, a weight of 10 was assigned to pure spruce forest cover types. Spruce mixed with other forest types is considered a moderately preferred host; hence, assigned a weight of 5. The weight column in table 4 is the weighted values used for all Forest Cover types in the overlay process.

Two primary data sets were used in the construction of the Establishment potential surface. These primary data sets are: Disturbance, and Host species. A weighted overlay (Table 5) was applied to these data which resulted in the final Establishment potential surface.

Host / 60%
Note, all Host surface data may be subject to some level of Establishment. That is, Host data that is spatially coincident with the Disturbance surface will of course have some of the highest Establishment values (e.g. 8 or 10). Conversely, Host data that are not spatially coincident with the Disturbance surface will have the lowest Establishment values (e.g. less than or equal to 7)

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. Aerial survey flights are termed as "local" if they can be completed within 1 day from the survey base and "regional' if more than 1 day is required to complete the survey reconnaissance. Surveys are flown in Southeast Alaska, Southcentral Alaska and Interior Alaska. The data represents cumulative effect for 1989-2002.
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
