Conifer Regeneration After Wildfire In Low-Elevation Forests Of The Colorado Front Range: Implications Of A Warmer, Drier Climate, Monica T. Rother Jan 2015

Conifer Regeneration After Wildfire In Low-Elevation Forests Of The Colorado Front Range: Implications Of A Warmer, Drier Climate, Monica T. Rother

Geography Graduate Theses & Dissertations

In recent years, concern has grown among researchers, land managers, and the public regarding potential shifts in forest resiliency to disturbances such as wildfire under warming climate conditions. We examined conifer regeneration after fire in low-elevation, ponderosa pine (Pinus ponderosa) forests of the Colorado Front Range (CFR). Given preliminary observations of limited post-fire conifer establishment, we developed the general hypothesis that warming temperatures and associated drought are less suitable for post-fire conifer regeneration. We surveyed juvenile conifer densities in six recently burned areas of the CFR and found that juvenile ponderosa pine and Douglas-fir (Pseudotsuga menziesii) densities were typically lower ...


Fine Scale Climatic And Soil Variability Effects On Plant Species Cover Along The Front Range Of Colorado, Usa, William Frank Preston Cumming Jan 2013

Fine Scale Climatic And Soil Variability Effects On Plant Species Cover Along The Front Range Of Colorado, Usa, William Frank Preston Cumming

Geography Graduate Theses & Dissertations

Fine scale studies are rarely performed to address landscape level responses to microclimatic variability. Is it the timing, distribution, and magnitude of soil temperature and moisture that affects what species emerge each season and, in turn, their resilience to fluctuations in microclimate. For this dissertation research, I evaluated the response of vegetation change to microclimatic variability within two communities over a three year period (2009-2012) utilizing 25 meter transects at two locations along the Front Range of Colorado near Boulder, CO and Golden, CO respectively. To assess microclimatic variability, spatial and temporal autocorrelation analyses were performed with soil temperature and ...
