Understory plant species showing significant variation across treatments.

Notes: Degrees of freedom = 3,18 for treatment; 2,18 for site; and 6,18 for treatment*site. Levels of treatment and site that do not share the same letter were significantly different in Tukey’s HSD post-hoc tests; the level with the highest mean is represented by letter A, the next highest by letter B, etc. Percent cover is the number of pin hits for each species divided by the total number of pin drops (123,480) in the experiment to date. Data for Indigofera sp. “small” are from only the most recent three surveys, as opposed to seven surveys for other species. Results for the remaining understory plant species are shown in Table S3.
