A model of ponderosa pine growth response to prescribed burning


Sutherland, Elaine Kennedy; Covington, W. Wallace; Andariese, Steve. 1991. A model of ponderosa pine growth response to prescribed burning. Forest Ecology and Management. 44: 161-173.

Our objective was to model the radial growth response of individual ponderosa pines to prescribed burning in northern Arizona. We sampled 188 trees from two study areas, which were burned in 1976. Within each study area, control and burned trees were of similar age, vigor, height, and competition index. At Chimney Spring, trees were older, less vigorous, and taller and had a higher competition index than at Brannigan. For each tree, periodic basal area increment (PBA1) was calculated for the years 1974-1984. To determine which variable would best model growth, post-fire growth (1977-1984) was correlated with the 3 year average of previous growth, crown ratio, competition index, and diameter.
