Can Aspen groves help mitigate wildfire?
Aspen stands have the potential to slow a running crown fire or cause it to change direction. Increasing the size of an aspen stand may reduce the rate of spread.
Aspen trees have more moisture, and do not contain the highly flammable resins that conifers do (such as, lodgepole, ponderosa, and Douglas fir).
This means that promoting aspen growth can bolster wildfire mitigation efforts.
We do this by thinning the canopy around aspen stands so there is less competition and to allow more light to reach the soil. Warm soil helps new aspen trees grow. Additionally, disturbance (like felling trees) can help aspen roots produce growth hormones.
