Long-Term Studies Show Herbivore Exclusion Alters Forest Plant Communities in U.S.
Two long-term ecological studies in the U.S. examined the effects of excluding large herbivores on forest plant communities. In Washington's Olympic Peninsula, 36 years without elk led to shrub overgrowth and loss of many smaller plant species, highlighting elk's role in maintaining diversity. Similarly, an 18-year study in New York found that deer exclusion allowed tree growth to sustain, while open plots saw woody plants halved. Both studies emphasize herbivores' complex influence on forest ecosystems and plant diversity.
