Watercraft inspections and decontaminations for invasive species in the state of Alaska

Overview: File geodatabase containing data related to watercraft inspections conducted by the U.S. Fish and Wildlife Service to prevent the spread of invasive species into the state of Alaska. It integrates multiple layers and tables that document inspection details, watercraft characteristics, and associated waterbody information. Feature layers and tables: Watercraft Inspections (parent): This layer records details of watercraft inspections including inspection locations, dates, whether inspections were conducted, vessel characteristics (such as type and presence of motors), and inspection outcomes like detection of nonnative species and decontamination types. Risk scores relating to likelihood of invasive species spread based on previous waterbodies visited are also documented, along with various inspection criteria such as standing water presence and equipment checks. Source Waterbodies (child): This layer captures information about waterbodies previously visited by watercraft. It classifies water types (freshwater, marine, brackish), provides geographic identifiers and risk assessments for invasive species. This contextual data helps understand potential invasive species sources. Destination Waterbodies (child): This layer describes the waterbodies that watercraft are headed to, noting water types and linking to corresponding inspections. It supports tracking the path of watercraft to identify potential routes for invasive species transmission. Observer Information (child): This table lists the inspectors performing watercraft checks, enabling personnel tracking and accountability. Previous Inspection States (child): This table enumerates states or provinces where watercraft had prior inspections, providing a historic inspection context critical for monitoring invasive species spread across regions.
