FIRE, DROUGHT AND GRAZING INTERACTIONS IN NORTHERN MIXED PRAIRIE
Livestock and Range Research Laboratory (LARRL)
2013 Annual Report
1a.Objectives (from AD-416):
Determine interacting effects of fire, weather and herbivory on northern mixed prairie communities.
1b.Approach (from AD-416):
We will examine the resistance and resilience of rangeland plants to the interactions of fire, drought and grazing applied with varying levels of severity and different timing in field and laboratory experiments to indicate whether disturbances have additive effects on plant response. Treatment effects will be evaluated by measuring biomass, bud banks, plant species composition and plant diversity before and after treatment.
Seasonal sampling of buds and pre- and post-fire bud assessment for summer, fall, and spring fires have been completed. Sampling for bud development relative to phenological stages has been completed. Analyses are being conducted for reporting of results. As ADODR, communications were daily through personal contact, phone and e-mail with a graduate student. Weekly planning meetings were conducted.
