USFWS Region 7 Alaska Nonnative Plant Surveys - 2025 Survey Data

Registros

Los datos en este recurso de registros biológicos han sido publicados como Archivo Darwin Core(DwC-A), el cual es un formato estándar para compartir datos de biodiversidad como un conjunto de una o más tablas de datos. La tabla de datos del core contiene 19.813 registros.

también existen 3 tablas de datos de extensiones. Un registro en una extensión provee información adicional sobre un registro en el core. El número de registros en cada tabla de datos de la extensión se ilustra a continuación.

Este IPT archiva los datos y, por lo tanto, sirve como repositorio de datos. Los datos y los metadatos del recurso están disponibles para su descarga en la sección descargas. La tabla versiones enumera otras versiones del recurso que se han puesto a disposición del público y permite seguir los cambios realizados en el recurso a lo largo del tiempo.

Cobertura geográfica

The geographic extent included much of southern, western, central, and northern Alaska, USA.

Cobertura taxonómica

We surveyed for selected lists of non-native vascular plant species. In most surveys we limited our searches to high priority invasive species, but in some surveys we surveyed exhaustively for all non-native vascular plant species.

Cobertura temporal

Datos del proyecto

In accordance with the orders of Executive Office of the President (2016) to prevent introduction, establishment, and spread of invasive species and to control and eradicate established populations, with an aim of minimizing their damage to the environment and natural resources, teams from the United States Fish and Wildlife Service, Alaska Region surveyed for and treated non-native plants on and around Alaska National Wildlife Refuges in Alaska. This dataset includes occurrences resulting from these efforts.

Métodos de muestreo

Four teams (Island Invasive Strike Team, Kenai National Wildlife Refuge Biology Team, North Region Early Detection Rapid Response Team, and South Region Early Detection Rapid Response Team) collected non-native plant data following Alaska Exotic Plant Information Clearinghouse database standards (AKEPIC, 2018, 2020, 2026). The Kenai National Wildlife Refuge Biology Team followed the protocol of Bowser (2025d) for elodea surveys.

Descripción de la metodología paso a paso:

1. We collected data in the field using one of multiple ESRI Survey123 (https://survey123.arcgis.com/) forms (Bowser, 2025b; USFWS R7 Invasive Species Data Coordination Team, 2025a, 2025c). Instructions for these forms are available from Bowser (2025a).
2. Data were checked using a Quarto (https://quarto.org/) script (USFWS R7 Invasive Species Data Coordination Team, 2025b) that ran R, version 4.4.2 (R Core Team, 2024) and used the R packages arcgisbinding, version 1.0.1.311 (Esri, 2024); fontawesome, version 0.5.3 (Iannone, 2024); leaflet, version 2.2.3 (Cheng et al., 2025); and sf, version 1.0-20 (Pebesma, 2018; Pebesma and Bivand, 2023). These data were reformatted to the Biotic Observation Minimum Specification format (U.S. Fish & Wildlife Service, National Wildlife Refuge System, Inventory & Monitoring Branch, 2023) using a Quarto script (USFWS R7 Invasive Species Data Coordination Team, 2026) that ran R, version 4.5.2 (R Core Team, 2025) and used the R packages arcgisbinding, version 1.0.1.311 (Esri, 2024); h3jsr, version 1.3.1 (O’Brien, 2023); sf, version 1.0-24 (Pebesma, 2018; Pebesma and Bivand, 2023); and uuid, version 1.2-2 (Urbanek and Ts’o, 2026).
