Spatial Patterns and Distance Distributions in Young Seeded Loblolly Pine Stands
Spatial patterns were examined for 40 5- to 12-year-old loblolly pine stands of seed origin using point-to-plant distance methods. The stands had been regenerated by seed tree, natural (old field), aerial, or broadcast seeding. Pielou's nonrandomness index indicated that clumping was prevalent in all regeneration methods. Index values were not correlated with age, stand density, or average tree sizes, and differences could not be attributed to regeneration method. Observed distance frequencies were further described by continuous distributions derived from Poisson and negative binomial assumptions of plant distribution used in quadrat (plot) sampling. The Pearson type XI distribution, derived from the negative binomial assumption, fit the observed distances well and should prove useful in spatial modeling. Forest Sci. 24:260-266.
