Tabular data set summarizing detection and location of invasive plants on islands in Alaska Maritime National Wildlife Refuge between July 14, 2024 and July 31, 2024. Data has been reformatted from its original format to align with the Alaska Exotic Plants Information Clearinghouse (AKEPIC; https://accs.uaa.alaska.edu/invasive-species/non-native-plants/) submission template.

Tabular datasets relating to invasive species detections in the northern Alaskan area. Data pertain to invasive species surveys conducted on the Arctic, Tetlin, and Kanuti National Wildlife Refuges by the Alaskan Invasive Species Program teams. Data were collected using a Survey123 form. Data were subsequently downloaded from the ArcGIS feature layer and manual quality control was performed at the end of each season by the project lead. Data were then reformatted to align with the AKEPIC data submission template (https://accs.uaa.alaska.edu/invasive-species/submit-data-to-akepic/) for submitting detection of invasive species information into the Alaska Exotic Plants Information Clearinghouse (AKEPIC) designed and run by the University of Alaska Anchorage (UAA) Alaska Center for Conservation Science (ACCS).

In 2010-2013, the U. S. Fish and Wildlife Service (USFWS) partnered with Utah State University to conduct invasive plant prioritization workshops and inventories on selected National Wildlife Refuges across the United States. The purpose of these workshops and subsequent inventories was to inform and improve the process of planning and implementing invasive plant inventories or early detection. These workshops highlighted the need for an objective, transparent and documented process for deciding which invasive plant species should be a focus of inventory or early detection (and ultimately management) and where. A result of this partnership is the Invasive Plant Inventory and Early Detection Prioritization Tool (IPIEDT) and associated user's guide. The tool is a Microsoft Access database (2010 or later) that utilizes site-specific knowledge and harnesses existing invasive plant information (invasive species risk rankings) to identify priority species and areas for inventory or early detection. The tool produces a ranked list of areas and invasive plant species to consider for inventory or early detection. Once the location and abundance of priority invasive plants are understood, this information can be used to decide what specific management strategies should be employed and where. Interior 1 Regional and Refuge staff used the database developed by Utah State and the Pacific Southwest Region to prioritize areas and invasive species at Ohio River Islands. The attached products are the result of that prioritization.

Exotic plant survey polygon data representing infested or non-infested areas including inventory, treatment, and monitoring efforts. Polygons are generated by 1) collecting point and line features and buffering them with a distance entered in the field, 2) collecting polygons features for large or irregular sized patches, or 3) collecting data within pre-existing "standardized" polygons that remain consistent from year to year. Data is collected by field personnel using mapping grade GPS and a statewide data collection protocol. INSTRUCTIONS FOR USE: See Supplemental Information details on how to use this geodatabase.

The Southwest Exotic Plant Mapping Program (SWEMP) is a collaborative effort between the United States Geological Survey and federal, tribal, state, county and non-governmental organization (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 data from Herbaria. The SWEMP database comprises a compilation of data submitted through 2006.
