Fire size and severity continue to increase across large parts of North America, driven by a combination of climate change and effects of human land use. Instrumental records are too short to fully understand patterns, trends, and drivers of fire that are necessary to model future fire. Tree-ring fire scars provide centuries-long records of fire regimes, including fire frequency, season, size, and fire-climate relationships. We compiled fire-scar site descriptions from > 100 researchers across the continent to produce the first North American tree-ring fire-scar network. These data provide descriptive information for all known tree-ring fire-scar sites in North America. Data fields include location, name, area and...
The data include ages and locations of presence/absence surveys for sagebrush (Artemesia tridentata) on the Bureau of Land Management Rio Grande del Norte National Monument, New Mexico. We sampled cross-sections of sagebrush along 11 General Land Office section survey lines and conducted growth ring analysis to produce inner-ring dates for 93 sagebrush plants. The presence/absence surveys were conducted along the same section lines as the growth ring samples and were compared to the original surveys from 1881 to assess vegetation change on the landscape.
