Data from: Six years of ecosystem-atmosphere greenhouse gas fluxes measured in a sub-boreal forest

Continuous tower-based measurements of the ecosystem-atmosphere exchange of CO2 and CH4 are presented, recorded over the period 2012–2018 and reported at a 30-minute time step at a sub-boreal forest in the northeastern United States. Additionally, we describe a five-year (2012–2016) dataset of chamber-based measurements of soil fluxes of CO2, CH4, and N2O (2013–2016 only), conducted each year from May to November. These data can be used for process studies, for biogeochemical and land surface model validation and benchmarking, and for regional-to-global upscaling and budgeting analyses.

White-tailed deer density estimates across the eastern United States, 2008

The QDMA spatial map depicting deer density (deer per square mile) was digitized across the eastern United States. Estimates of deer density were: White = rare, absent, or urban area with unknown population, Green = less than 15 deer per square mile, Yellow = 15 to 30 deer per square mile, Orange = 30 to 40 deer per square mile, or Red = greater than 45 deer per square mile. These categories represent coarse deer density levels as identified in the QDMA report in 2009 and should not be used to represent current or future deer densities across the study region.

Northern Forest Futures Database

The Northern Forest Futures database (NFFDB) supports the reporting of both current and projected future forest conditions for the 20 states that make up the U.S. North, an area bounded by Maine, Maryland, Missouri, and Minnesota. The NFFDB database and attendant reporting tools are available…
