The moisture, ether extractive, and energy content of ponderosa pine (Finns ponderosa Laws.) and Douglas-fir (Pseudotsuga menziesii L.) foliage were measured during two fire seasons. The moisture content of 1and 2-year-old needles was found to rise throughout the summer. The ether extractive content was highest in the fir foliage at the end of summer when fire severity is generallj'^thought to be highest. Pine foliage extractive content was high throughout the sample period. The energy content of the extracted leaves and the extractives varied through the summer. There may be a relationship between the extractives and crown fire potential in these species. 53 p., 1963. C. A. Connaughton and T. E. Maki. The volatility content (particularly moisture) of evergreen foliage during periods of drought stress.
