Jonathan H. Titus and John G. Bishop Propagule limitation and competition with nitrogen fixers limit conifer colonization during primary succession Journal of Vegetation Science 25
On Mount St. Helens many primary successional surfaces were bare while others were colonized by nitrogen-fixing plants which facilitate community development. Dense N-fixing plants inhibit Pseudotsuga menziesii establishment via moisture competition. However, in sparsely vegetated areas, conifer seeds had high establishment probability, demonstrating strong propagule limitation. Conifer establishment has decreased in densely vegetated areas but accelerated in sparsely vegetated areas.
