T6.4 Temperate alpine grasslands and shrublands
T6. Polar/alpine (cryogenic) biome
Profile summary
Full profile at https://global-ecosystems.org/explore/groups/T6.4
Brief description
Temperate alpine grasslands and shrublands occur above the treeline, on temperate and boreal mountains worldwide. Seasonal productivity is limited by cold and snow cover, often with strong winds. Mosses, liverworts, lichens, flowering plants and low shrubs generally form a continuous cover, except where strong winds and dry conditions limit vegetation to sparse lichens and dwarf shrubs. Most fauna is seasonally active during warmer summer months, with insects and vertebrates having adaptations to extreme cold, including hibernation. Many species have restricted distributions, with strong barriers to dispersal between mountains.
Key features
Mountain systems above the physiological limits of trees, with sparse to continuous cover of herbaceous plants, cryptogams and dwarf shrubs that may be morphologically adaptated to extreme cold..
Overview of distribution
Ttemperate and boreal zones of the Americas, Europe, central Eurasia, west and north Asia, Australia, and New Zealand.
Map description
Terrestrial ecoregions containing major or minor occurrences of this ecosystem functional group were identified by consulting available ecoregion descriptions (Dinerstein et al. 2017), global and regional reviews, national and regional ecosystem maps, locations of relevant examples, and proofed by expert reviewers. Consequently they are coarse-scale indicative representations of distribution, except where they occupy small ecoregions. Ecoregions were mapped at 30 arc second spatial resolution..
