OAKS IN A CHANGING CLIMATE

Research indicates that as a result of climate change, the Pacific Northwest will experience warmer temperatures,  drier conditions, and a higher likelihood of drought and wildfire.  Because oaks are relatively drought tolerant and resistant to fire, they are predicted to do well in these future conditions compared to less drought tolerant species such as Douglas-fir and other conifers that are encroaching oak woodlands in the lowlands and foothills. 

Climate benefits of oaks

 In open areas such as agricultural and range lands, oaks can provide critical forage and shade for wildlife and livestock. And in riparian areas, established oaks can provide important shade, lowering stream temperatures and benefiting aquatic species.  Where low density housing interfaces with natural vegetation, oak savannas or thinned woodlands can serve as a natural firebreak, protecting structures from potential fire risk.  

Climate mitigation and adaptation

Trees that are growing will  sequester carbon - an important component of climate change mitigation.  Avoiding conversion of tree cover to other uses helps to maintain carbon already stored in existing trees.

As we enter a phase of increasing risk from wildfires, it is becoming  important to incorporate climate adaptation into our restoration strategies. Investing in tree thinning, reducing fuel loads that have accumulated over time, and reintroduction of prescribed fire can ensure that oak habitats are able to thrive under these predicted future conditions.
