This study analyzes the effects of compost on native plant establishment in the presence of a non-native species, Bromus inermis (smooth brome). In a replicated greenhouse study, I applied four compost treatments to pots containing native plant species and smooth brome: a control group with no compost added, and three other treatments in which compost was added at 10%, 20%, and 30% by volume. After 7 weeks of growth, I compared the dry weight of the aboveground biomass and the abundance of each species across treatments. As the compost increased, 4 grass species reacted positively and increased in biomass. However, forb species did not follow this trend, and their biomass decreased as the compost levels increased.born digitalStudent worksengCopyright and other restrictions may apply.
