TF1.3 Permanent marshes

Biome: TF1. Palustrine wetlands biome

Contributors:
(texts)

Permanent marshes occur throughout tropical and temperate regions of the world in flat areas with stable water levels close to the surface. They are essentially treeless, with extensive reedbeds and aquatic grasses, interspersed with patches of open water. Food webs are strongly influenced by highly productive algae and plants, providing food for large numbers of invertebrates, waterbirds, reptiles, and mammals.

Key Features

Shallow permanently inundated freshwater wetlands, dominated by herbaceous macrophytes, supporting high primary productivity and complex trophic networks with abundant insects, birds and amphibians.

Overview of distribution

Mainly on floodplains in catchments with humid tropical or temperate climates.

Maps

Maps are indicative of global distribution patterns are not intended to represent fine-scale patterns. The maps show areas of the world containing major (coloured red) or minor occurrences (coloured yellow) of each ecosystem functional group. See general notes on maps.

TF1.3.web.orig_v1.0

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.
