Plant diversity in tree habitats on vegetable farms in Champlain Valley, Vermont
Researcher: S’ra DeSantis
This study was designed to characterize the extent to which farm management practices, biophysical features, and landscape variables affected plant species richness, abundance, and diversity of treed habitats on vegetable farms in the Champlain Valley of Vermont. Results showed that landscape variables were the most influential factors determining plant diversity, followed by biophysical features. Management practices did not influence plant diversity metrics except for species diversity in the overstory, which surprisingly was higher in treed habitats on conventional farms.
Other studies have observed that increasing levels of landscape heterogeneity and treed habitats adjacent to organic farms corresponds to higher levels of plant diversity. However this study found the opposite, most likely because the studied region is situated in a forested matrix, as opposed to an agricultural matrix. Overall, 82 % of the species inventoried in the understory and overstory were native, revealing that treed habitats in agricultural landscapes have the capacity to conserve native plant diversity.
