Little to no difference was found in soil nutrient concentrations between snowmelt regimes. 2) Late regimes had highest NDVI values, while those of Early and Mid regimes were similar. 3) Vegetation composition differed between Early and Late regimes, with Dryas octopetala and Luzula arcuata subsp. confusa characterizing the former and Equisetum arvense and Eriophorum scheuchzeri the latter. 4) Trends for plant nutrient contents were similar to those found in a nearby snow manipulation experiment. Snow distribution and time of snowmelt played an important role in determining regional environmental heterogeneity, patchiness in plant community distribution, their species composition and plant phenology.
