Do Pine stands act as a barrier to Spanish moss dispersion?

Some authors have hypothesized that pine stands may act as a barrier to Spanish moss dispersion. However, no study has formally examined the spatial distribution of Spanish moss in a pine stand to determine what factors are most predictive of where it is found. The present study used logistic regression to examine predictors of the occurrence of Spanish moss in a burn-managed pine stand at the Lake Louise Research Center. Results based on 165 circular quadrats (representing 1098 trees) revealed that the distance to hardwood source populations along the edge of the stand was most predictive of Spanish moss occurrence, followed by the average age of the hardwoods and species richness. Our results support the hypothesis that pine stands may be acting as a dispersal barrier, as Spanish moss was most commonly found in ecotonal areas along the edges and rarely in the center of the stand.
