Regional variation for tree critical loads across the U.S.
This dataset encompasses a re-analysis of data from Horn et al. (2018) to determine regional tree growth and survival response to nitrogen and sulfur deposition across the United States. Tree responses are matched with additional climate (temperature, precipitation), edaphic (soil pH), deposition (N and S deposition), and biotic covariates (tree deciduousness and mycorrhizal association). A full list of datasets and R code are available in Appendix S3 in the forthcoming peer-reviewed publication. Horn, Kevin J., et al. "Growth and survival relationships of 71 tree species with nitrogen and sulfur deposition across the conterminous US." PloS one 13.10 (2018): e0205296. For more information about the each file included, see "README_TreeCLA1_FFGC.pdf" in the supporting documents tab. A data dictionary is included with the each file as additional "README" or "meta" tabs in .xlsx documents and a forthcoming peer reviewed publication describes the methodologies. This dataset is associated with the following publication: Dalton, R.M., J.N. Miller, T. Greaver, R.D. Sabo, K.G. Austin, J.N. Phelan, R.Q. Thomas, and C.M. Clark. Regional variation in growth and survival responses to atmospheric nitrogen and sulfur deposition for 140 tree species across the United States. Frontiers in Forests and Global Change.

Changes in forest tree species composition for 2010-2100
공공데이터포털
This data is from Clark et al. (2023), "Future climate change effects on US forest composition may offset benefits of reduced atmospheric deposition of N and S." (https://onlinelibrary.wiley.com/doi/10.1111/gcb.16817). The dataset provides the decadal data (2010, 2020, etc., to 2100), for estimates of biomass and stem count, for each county (FIPS) in the lower 48 states, for the 94 tree species analyzed in Horn et al. (2018), separately for the 20 climate and atmospheric deposition scenarios examined in the Clark et al. manuscript. Summary tables and key supporting information are also provided. The data are too large to upload to Science Hub (>10 GB) and are instead available on the DataDryad here: https://datadryad.org/stash/dataset/doi:10.5061/dryad.tht76hf4f. This dataset is associated with the following publication: Clark, C., J. Phelan, J. Ash, J. Buckley, J. Cajka, K. Horn, R.Q. Thomas, and R.D. Sabo. Future climate change effects on U.S. forest composition may offset benefits of reduced atmospheric deposition of N and S. GLOBAL CHANGE BIOLOGY.

Nitrogen Deposition and Climate Change Effects on Tree Species Composition and Ecosystem Services: A Cohort Analysis in
공공데이터포털
A tree database representing a single cohort of trees was assembled using data from U.S Forest Service monitoring plots. Applying existing species specific response relationships from Thomas et al. (2010), we simulated how forest stands in a 19-state study area would change (biomass and stem density) from 2005 to 2100 under 12 different future N deposition – climate scenarios based on historic levels, current policy and potential futures. This dataset is associated with the following publication: van Houtven, G., J. Phelan, C. Clark, R. Sabo, J. Buckley, R.Q. Thomas, K. Horn, and S. LeDuc.
