18 Douglas-fir/oceanspray forest Forests composed of mixed Douglas-fir and ponderosa pine occur in the U.S. Rocky Mountains and east of the Cascade Range. Fire exclusion and historic high-grade logging of mature ponderosa pine has favored dominance of the shade-tolerant Douglas-fir. This 80- to 250-year-old stand was treated with prescribed fire 5 years previously. This fuelbed was developed based on data from North Cascades National Park Complex. 240,260,330,340 2 1 118 8 1 2
