Abstract:

This dataset includes information on post-fire seed cone production, seedling establishment, seedling densities, and layers used in spatially-explicit predictions of post-fire forest recovery throughout 15 wildfires in southern Colorado and northern New Mexico, USA. All fires were selected from the Monitoring Trends in Burn Severity (MTBS) database using the following criteria: 1) vegetation type – fires must have occurred in areas with dominant components of pine-oak, ponderosa pine, or dry mixed-conifer vegetation types, 2) accessibility – fires must have occurred on accessible public land, or on large private parcels for which we were permitted access, and 3) fires must have had only minimal areas of overlap with other fire perimeters (i.e., “reburns”). Approximately 40 post-fire regeneration plots were established throughout each fire (n = 555). Within each plot, we recorded species-specific counts of post-fire seedling density, characterized pre- and post-fire forest structure, and quantified post-fire groundcover. Within each plot, we also collected up to two destructively sampled seedlings/stems of ponderosa pine, Douglas-fir, lodgepole pine, Gambel oak, and/or aspen (n = 701). We identified the establishment year of conifers by dating the root-shoot boundary of each seedling and the establishment year of resprouting angiosperm trees by dating the innermost ring near ground level. We also dated cone production of ponderosa pine in areas adjacent to fire perimeters or in low-severity areas within fire perimeters. To reconstruct seed cone production, we used counts of cone abscission scars in 5-6 branches on 154 trees spanning 27 sites throughout eight fires. These fires were selected to span the geographic and climatic range of our sites. Seed cone production data were aggregated to average annual production at the fire-level. We also used post-fire regeneration plot data and geospatial datasets (i.e., 1-meter aerial imagery and gridded climate data) to predict post-fire seedling density throughout each fire perimeter. These field-derived and spatial datasets, associated with Rodman et al. (2019), were part of the Joint Fire Science Project ID #: 17-2-01-4.
