Incidence of western gall rust infection in each of 10 replicated forest openings having diameter height ratios of 2:1, 4:1, and 6:1 was determined along two perpendicular 1-m wide transects. Infection frequencies were not significantly different among the different-sized openings. No pine regeneration was present in openings with diameter:height ratios of 0.5:1 or 1:1, thus precluding direct comparison of our results with those obtained from three other tree host–parasite studies in which disease incidence was greatest in small openings.
