The effect of different grazing intensities (no grazing, light, moderate, and heavy) of Black Brant (Branta bernicla) gosling on grazing lawns planted to Carex subspathacea and native slough levees (T. palustris) was measured on the Yukon-Kuskokwim Delta, Alaska (61Ëš N, 165ËšW). Above ground biomass and offtake of biomass was measured pre-, mid-(after 4 h), and post-trial (8 h) in both habitats. Offtake was calculated as the difference between the average biomass measured before and after a given portion of treatment. Every two hours of the 8 hour grazing treatment gosling grazing behavior (feeding or not) was recorded every minute for one hour.
