Amphibian Monitoring for the Greater Yellowstone Network: 2005-2024 – Data Package

This data package contains the final flattened csv file and associated metadata for data collected following the amphibian and wetland monitoring protocol under the Greater Yellowstone Inventory and Monitoring Network. Amphibian and wetland monitoring surveys have been conducted annually in Grand Teton and Yellowstone national parks and John D. Rockefeller, Jr. Memorial Parkway since 2005. The main goals of this program are to estimate wetland flooding and amphibian breeding occurrence rates. These annual measures of amphibian occurrence and wetland dynamics offer insights about changing wetland conditions and amphibian status and trends, contributing to local, regional, and national level trend analysis. This work, when combined with historical data, will provide managers and the public with information on a class of native fauna and on wetland characteristics that are important for understanding long-term trends or climate induced changes to wetlands.

This data package includes all wetland site visits and associated data from 2005-2024. The methodology consists of dual-observer visual encounter surveys with single visits per year to a target site (although some sites were visited multiple times per year in 2005 and 2006). The data collected in 2005 represent trial methods and are not intended for analysis with or comparison to data collected starting in 2006. Catchments in the low-quality stratum of the study design were found to provide scant information due to the low occurrence of detected breeding sites in the small number of catchments that GRYN was able to survey. Therefore, this stratum has been largely excluded from annual monitoring since 2011. Additional habitat and weather data were collected on site. The annual goal of the protocol is to conduct surveys in over 300 sites dispersed throughout 31 core catchments (sampling units). However, the Greater Yellowstone Network crews often survey more areas when resources allow. All four native species targeted for occupancy monitoring are surveyed for and found within the core catchments: Boreal Chorus Frog (Pseudacris maculata), Columbia Spotted Frog (Rana luteiventris), Western Tiger Salamander (Ambystoma mavortium), and Western Toad (Anaxyrus boreas). Note that Western Toad is operationally protected within Grand Teton and Yellowstone national parks as per 2019 memos (https://irma.nps.gov/DataStore/Reference/Profile/2263658; https://irma.nps.gov/DataStore/Reference/Profile/2263657), which limits unauthorized use or sharing of their data and location information.

背景概述

该数据集为美国国家公园管理局发布的大黄石网络两栖动物监测数据包，涵盖2005年至2024年期间在大黄石、大提顿国家公园等区域采集的两栖动物和湿地监测数据。数据集旨在通过双观察者视觉调查方法，评估四种本地两栖动物物种的繁殖发生率和湿地动态，为长期生态趋势和气候变化影响研究提供支持。需要注意的是，2005年数据为试验方法，且西部蟾蜍数据受操作保护限制。
