Climate data for RPA 2020 Assessment: MACAv2 (METDATA) historical modeled (1950-2005) and future (2006-2099) projections for the conterminous United States at the 1/24 degree grid scale

Datasets Posted on: December 30, 2020
The 2020 Resources Planning Act (RPA) Assessment will include climate change as a driver affecting natural resources on all forest and rangelands in the United States. These climate projections, along with projections for population dynamics, economic growth, and land use change in the United States, comprise the RPA scenarios.

Species occurrence data from the aquatic eDNAtlas database

Datasets Posted on: December 30, 2020
The eDNA samples in the eDNAtlas database describe species occurrence locations and were collected by the U.S. Forest Service and numerous agencies that have partnered with the National Genomics Center for Wildlife and Fish Conservation (NGC) throughout the United States. This project began in 2015, but updates will include legacy data that were collected using the same protocol. The eDNAtlas database consists of three feature classes.

AmeriFlux site visit report and data for the Glacier Lakes Ecosystem Experiments Site (US-GLE)

Datasets Posted on: December 30, 2020
This report and data summarize the AmeriFlux Tech team site visit to the Glacier Lakes Ecosystem Experiments Site (GLEES) in southeastern Wyoming. For this campaign, the AmeriFlux portable eddy covariance system (PECS) was deployed near the in situ GLEES micro-meteorological sensors.

Current and future plant hardiness zones for the conterminous United States

Datasets Posted on: December 30, 2020
This data publication includes raster digital files containing plant hardiness zones of current climate (1981–2010) and future climates (2070–2099; CanESM2, GFDL-ESM2G, and HadGEM2-ES general circulation models at representative concentration pathway 8.5) in the conterminous United States. Plant hardiness zones represent the coldest day of the year, averaged over 30 years.

Forest-level appendices to the assessment of the influence of disturbance, management activities, and environmental factors on carbon stocks of U.S. National Forests

Datasets Posted on: December 30, 2020
This is a supplement for the General Technical Report RMRS-GTR-402 “Assessment of the influence of disturbance, management activities, and environmental factors on carbon stocks of U.S. National Forests" (Birdsey et al. 2019). Included are nine appendices that contain forest-level carbon information, model results, key figures, and interpretation for individual national forests across the nine National Forest System regions in the U.S.

RPA Historical observational data (1979-2015) for the conterminous United States at the 1/24 degree grid scale based on MACA training data (METDATA) (2nd Edition)

Datasets Posted on: December 30, 2020
This data publication contains a gridded historical (1979-2015) dataset for the conterminous United States that has been summarized to the monthly time scale. This monthly historical dataset was developed using the daily MACA observational data (METDATA), also called MACA Training Data (https://www.northwestknowledge.net/metdata/data/).

Field plot measures and fuel treatment units used to assess the effectiveness of (WUI) fuel treatments burned through by the 2007 East Zone and Cascade megafires in central Idaho (2nd Edition)

Datasets Posted on: December 30, 2020
This data publication contains both vector and tabular digital data providing field plot measures and fuel treatment units used to assess the effectiveness of (WUI) fuel treatments burned through by the 2007 East Zone and Cascade megafires in central Idaho.

In the hot seat: Mexican Spotted Owl habitat could dry up in the face of climate change

Publications Posted on: December 14, 2020
Global climate change represents a growing conservation threat, but our understanding of the effects of climate change remains limited for most species. Understanding these effects may be particularly important for species that are already threatened by other factors, because climate change may interact synergistically with those factors. One such species is the threatened Mexican Spotted Owl (Strix occidentalis lucida).

Forest and woodland replacement patterns following drought-related mortality

Publications Posted on: December 14, 2020
Forest vulnerability to drought is expected to increase under anthropogenic climate change, and drought-induced mortality and community dynamics following drought have major ecological and societal impacts. Here, we show that tree mortality concomitant with drought has led to short-term (mean 5 y, range 1 to 23 y after mortality) vegetation-type conversion in multiple biomes across the world (131 sites).

Divergent forest sensitivity to repeated extreme droughts

Publications Posted on: December 11, 2020
Climate change-driven increases in drought frequency and severity could compromise forest ecosystems and the terrestrial carbon sink. While the impacts of single droughts on forests have been widely studied, understanding whether forests acclimate to or become more vulnerable to sequential droughts remains largely unknown and is crucial for predicting future forest health.
