Stands of Pinus contorta Dougl. on contiguous physiographic areas near West Yellowstone, Montana, vary greatly in fruiting habit. The number of serotinous cones per acre was estimated to be 153,000 in an even-aged 88-year-old stand on rolling topography, but only 69,000 in an adjacent uneven-aged stand on an alluvial flat. Ninety percent or more of the cones were closed on 58 percent of the trees in the even-aged stand and on 38 percent of the trees in the uneven-aged stand.
