Project ID: E2012-01Abstract
Tall fescue invasion of grazing land is an increasing concern due to its association with a fungal endophyte that can produce compounds toxic to livestock and wildlife. The project compared patch-burn grazing as a management tool relative to complete pasture burning in tall fescue-invaded pastures.Key Question: Can patch-burn grazing could serve as a better management tool in reducing tall fescue relative to complete pasture burning? Is the fungal endophyte associated with tall fescue detectable in the pastures and are its alkaloids detectable in the feces of the cattle that had grazed the pastures? How does the presence of tall fescue affect the litter and nutrient dynamics of the grassland, which could have implications for using fire as a management tool?
