Enregistrements de données

Les données de cette ressource occurrence ont été publiées sous forme dune Archive Darwin Core (Darwin Core Archive ou DwC-A), le format standard pour partager des données de biodiversité en tant quensemble dun ou plusieurs tableurs de données. Le tableur de données du cœur de standard (core) contient 19 813 enregistrements.

3 tableurs de données dextension existent également. Un enregistrement dextension fournit des informations supplémentaires sur un enregistrement du cœur de standard (core). Le nombre denregistrements dans chaque tableur de données dextension est illustré ci-dessous.

Cet IPT archive les données et sert donc de dépôt de données. Les données et métadonnées de la ressource sont disponibles pour téléchargement dans la section téléchargements. Le tableau des versions liste les autres versions de chaque ressource rendues disponibles de façon publique et permet de tracer les modifications apportées à la ressource au fil du temps.

Couverture géographique

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

Couverture taxonomique

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.

Couverture temporelle

Données sur le projet

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.

Méthodes déchantillonnage

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.

Description des étapes de la méthode:

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).
