Horizon Scan for Vertebrates in Trade
공공데이터포털
This is a dataset summarizing filtering criteria and rapid risk assessments for ~25,000 species undertaken during a data-driven horizon scan of imported fish, amphibians, reptiles, birds, and mammals. The files represented in this dataset are the following: 1) 'species_filtering_metadata_table.xlsx' is the tabular summary of all intake list species names and the reason for inclusion/exclusion. 2) 'review_scores.xlsx' is the tabular summary of taxa expert risk assessment scores for species included after filtering. These data will be relayed to the U.S. Fish & Wildlife Service for further assessment and prioritization related to import regulation.
Evaluating regulations and surveillance as risk-mitigation to the emerging amphibian pathogen Bsal- Data release
공공데이터포털
Results of a literature search performed December 1, 2020. The tables in this document summarize the publications fitting in this search criteria and are split into the publications that update the list of international species that could carry Bsal (Appendix 1 Table S1). Number of individual live amphibians imported in categories of urodelan (salamander, newt, and related taxa) species restricted under the interim regulations and not listed, species not listed on the regulations that have had Bsal detected, notably Bombina spp., anuran species in the genus Rana, and Xenopus (including African clawed frogs) as a comparison of species not thought to be susceptible to Bsal, but commonly imported (Appendix 3 Table S1). Data and relative risk scores per county used for the risk analysis of B. salamandrivorans invasion, consequences, and surveillance for U.S. salamanders. All variables were scaled from 1, lowest relative risk, to 4, highest relative risk. Import and introduction risk scores were calculated from the average live imports per year for the pre-action risk period (2010-2015) and post-action risk period (2016-2019) (Appendix S3 Table S2).

Spatial data layers for a site prioritization tool for invasive species
공공데이터포털
These spatial layers were created to provide estimates of non-native species invasion risk across the contiguous United States based on proximity to human population centers and transportation corridors, and proximity to known locations of non-native species. To calculate the human transport risk layer we estimated the proximity to human population centers, transportation corridors, and speed of movement across the landscape. To calculate invasion risk based on known locations of non-native species, we gathered over 30 million records of non-native species occurrences across the contiguous United States from online databases to create nationwide maps of non-native species richness by species type: amphibians, fish, invertebrates, mammals, mollusks, plants, and reptiles.
