The Establishment Potential Surface for Ips typographus was produced in the State of Alaska conterminous in 1 square kilometer (km2) units by the U.S. Forest Service, Forest Health Technology Enterprise Teams (FHTET) Invasive Species Program.
The Establishment Potential Surface for Sirex noctilio was produced for the conterminous United States in 1 square kilometer (km2) units by the U.S. Forest Service, Forest Health Technology Enterprise Teams (FHTET) Invasive Species Steering Committee. The products intended use in conjunction with the Introduction Potential Surface is to develop a Susceptibility Potential Surface for Sirex noctilio. Four primary datasets with standardized values from 0 to 10 were used as variables in the analysis. Each dataset was multiplied by its arithmetic weight and the resultant values were combined in a weighted overlay (Eastman 1999). The final Establishment Potential Surface output values also range from 0 to 10; with 10...
The Exotic (EXO) and Native (NAT) biodiversity features represent exotic and native plant species communities in the Georgia Basin. These features (or rasters) were created following similar methods as Schuster & Arcese (2013), wherein they modelled and mapped bird species distributions using presence-absence data from ebird (http://ebird.org/content/ebird/about/; Sullivan et al. 2009). Plant species occurrence data were drawn from several sources (Boag 2014; Dr. E Gonzales; Dr. Joe Bennett; E-Flora BC 2013). Data for the 20 most abundant native and exotic plant species (40 species total) identified by Bennett (2014) were used to map the NAT and EXO communities, respectively (species list can be found in Appendix...

This map shows risk models for invasive species within the ecoregion. Samples of invasive species are presenting -- falling within 4 categories (exotic, annual grasses, noxious forbs, and woody riparian). Bioclimate data for cheatgrass and tamarisk weed is also shown. The input dataset used for all analysis done for these models are also included. These data are provided by Bureau of Land Management (BLM) "as is" and may contain errors or omissions. The User assumes the entire risk associated with its use of these data and bears all responsibility in determining whether these data are fit for the User's intended use. These data may not have the accuracy, resolution, completeness, timeliness, or other characteristics...

The dataset provides a near real time estimation of 2020 herbaceous mostly annual fractional cover predicted on July 1st with an emphasis on annual exotic grasses Historically, similar maps were produced at a spatial resolution of 250m (Boyte et al. 2019 https://doi.org/10.5066/P96PVZIF., Boyte et al. 2018 https://doi.org/10.5066/P9RIV03D.), but starting this year we are mapping at a 30m resolution (Pastick et al. 2020 doi:10.3390/rs12040725). This dataset was generated using in situ observations from Bureau of Land Management’s (BLM) Assessment, Inventory, and Monitoring data (AIM) plots; weekly composites of harmonized Landsat and Sentinel-2 (HLS) data (https://hls.gsfc.nasa.gov/); relevant environmental, vegetation,...

The invasion paradox describes the co-occurrence of independent lines of support for both a negative and a positive relationship between native biodiversity and the invasions of exotic species. The paradox leaves the implications of native?exotic species richness relationships open to debate: Are rich native communities more or less susceptible to invasion by exotic species? We reviewed the considerable observational, experimental, and theoretical evidence describing the paradox and sought generalizations concerning where and why the paradox occurs, its implications for community ecology and assembly processes, and its relevance for restoration, management, and policy associated with species invasions. The crux...

Locations of exotic (Invasive) plant species mapped by CBI on the Crestridge Ecological Reserve in 2000.
The Establishment Potential Surface for Ips typographus was produced for the conterminous United States in 1 square kilometer (km2) units by the U.S. Forest Service (USFS), Forest Health Technology Enterprise Teams (FHTET) Invasive Species Steering Committee; a multidisciplinary team with participation from USFS and the USDA Animal and Plant Health Inspection Service (APHIS).

We used Malaise traps to examine the aerial arthropod community in riparian habitats dominated by native willow, exotic saltcedar, or a mixture of these two tree species in central Arizona, USA. Over the course of three sampling periods per year in 2003 and 2004, native habitats had significantly greater diversity (Shannon–Wiener) and supported different arthropod communities compared to exotic habitats, while mixed habitats were intermediate in terms of diversity and supported an arthropod community statistically indistinguishable from the exotic site. The composition of arthropod communities varied significantly between the two years, and there was an approximately two-fold difference in richness and diversity....

The Introduction Potential Surface for Sirex noctilio was produced for the Conterminous United States (CUS) in 1 square kilometer (km2) units by the U.S. Forest Service, Forest Health Technology Enterprise Teams (FHTET) Invasive Species Steering Committee. The products intended use in conjunction with the Establishment Potential Surface is to develop a Susceptibility Potential Surface for Sirex noctilio. Three primary datasets with standardized values from 0 to 10 were used as variables in the analysis. Each data set was used in a weighted overlay process where Principal Ports = 33% and Markets = 33% and Distribution centers = 34%. Each of the variables was used to depict potential locations where Sirex noctilio...

The Southwest Exotic Plant Mapping Program (SWEMP) is a collaborative effort between the United States Geological Survey and federal, tribal, state, county and NGO partners in the southwest. This project is an ongoing effort to compile and distribute regional data on the occurrence of non-native invasive plants in the southwestern United States. The database represents the known sites (represented by a point location, i.e. site) of non-native invasive plant infestations within Arizona and New Mexico, and adjacent portions of California, Colorado, Nevada and Utah. These data, collected from 1911 to 2006, represent the field observations of various state, federal, tribal and county agencies, along with some specimen...
Summary of Susceptibility Potential Surface for Sirex noctilio: May 9, 2006 Website URL: http://www.fs.fed.us/foresthealth/technology/products.shtml. The Susceptibility Potential surface for Sirex noctilio was produced for the conterminous United States in 1 square kilometer (km2) units by the U.S. Forest Service, Forest Health Technology Enterprise Teams (FHTET) invasive Species Steering Committee. The products intended use is to develop a detection strategy for Sirex noctilio. The Susceptibility Potential Surface was produced by combining the Sirex noctilio Introduction and Establishment Potential Surfaces in a final equal weighted overlay.
This is a public dataset for the Department of Transportation, Bureau of Transportation statistics. The public database consists of four tables. One of the tables is a spatial table: INTERMODAL_FACILITY. The three other tables consist of attribute data for the database: INTERMODAL_CARGO, INTERMODAL_COMMODITY and INTERMODAL_DIRECTIONALITY. His database was based on the requirements from the Commodity Flow Survey and with the different modes of DOT, supervised by BTS. The database will extend its design to support all of he modes within the DOT and in reference to modes involved with Intermodal transfer.
