Grazing and substrate interact to affect native vs. exotic diversity in roadside grasslands
This short term study in California examined the vegetative cover of ungrazed roadside verges to adjacent grazed pastures in the inner northern coastal range (38° 40’ N; 122° 25’ W). Paired plots (grazed vs. ungrazed) were selected across two soil types (serpentine vs. non serpentine) with percent cover and height of all native and exotic plants. Site characteristics and cover of rock, litter, burrowing, overstory and bare ground were also recorded.
