Planting strategies for drought-resistant ponderosa pine - 0 views

MiamiOH OARS on 06 Sep 17The objectives of this Agreement are to improve the resilience of once-forested areas under warming and drying climate by collecting seeds from trees located in BAND that appear to drought-resistant, propagating those seeds, and planting seedlings that are within the natural range of variability for the biophysical setting of BAND, but may be better suited to the warmer drier site; and to conduct research that will inform future restoration projects in post-burned areas. In accordance with Section 4.4.2.2 of MP2006, the genetic type used in these plantings would approximate the extirpated genetic type because all of the seeds will have been collected from within BAND and the seedlings will be planted within the natural range of variability for those species. Replanting would occur on sites severely burned during recent human-caused wildfires in BAND. These fires have burned with uncharacteristic severity, the extent of which is far outside the range of historical variability. Recovery along a natural successional pathway is impeded by the extent of the high-severity patches.
