The response of the salt-marsh plant communities to grazing by lesser snow geese (Chen caerulescens caerulescens) and isostatic uplift at La Perouse Bay, Manitoba, (58Ã‹Å¡ 04Ã¢â‚¬â„¢ N, 94Ã‹Å¡ 30Ã¢â‚¬â„¢ W) was examined on short- and long-term scales using a multiple state model. Data presented here include the results from a current study and also previously published floristic and biomass data. These two annotations can be found in RSIS and are both by Jefferies (1988). Changes in vegetative composition relative to isostatic uplift was measured in three stable vegetative states: ungrazed swards dominated by Calamagrostis Ã¢â‚¬â€œFestuca (state K), grazed Calamagrostis Ã¢â‚¬â€œFestuca (state C), and grazed Puccinella-Carex (state A). Floristic composition and biomass inside and outside exclosures were measured (1986-1987) by removing sections of turf and clipping biomass at ground level.
