Overview

A detailed profile for this species is sourced from the IUCN Red List of Threatened Species as assessments become available.

The Large Marsh Grasshopper faces severe population declines primarily due to wetland drainage and agricultural intensification across its European range. Habitat fragmentation has isolated remaining populations in small, disconnected marsh fragments, reducing genetic diversity and increasing vulnerability to local extinctions. Climate change poses an additional threat through altered precipitation patterns that affect the water levels critical for maintaining suitable breeding habitats.

Threat summary

Habitat

The Large Marsh Grasshopper inhabits wet meadows, marshes, and boggy areas with tall grasses and sedges, particularly favoring sites with fluctuating water levels. It requires areas with both dry patches for basking and moist zones for feeding and reproduction.

Frequently asked questions

Why is Large Marsh Grasshopper classified as Vulnerable?
Large Marsh Grasshopper is classified as Vulnerable because the population is declining and the species faces a high risk of extinction in the medium-term future if current pressures continue. The Large Marsh Grasshopper faces severe population declines primarily due to wetland drainage and agricultural intensification across its European range. Habitat fragmentation has isolated remaining populations in small, disconnected marsh fragments, reducing genetic diversity and increasing vulnerability to local extinctions. Climate change poses an additional threat through altered precipitation patterns that affect the water levels critical for maintaining suitable breeding habitats.
Where does Large Marsh Grasshopper live?
Large Marsh Grasshopper occurs in Åland Islands, Andorra, Austria, Belarus, Belgium, and Bulgaria (plus 32 other countries). Country-level distribution data is sourced from the IUCN Red List and cross-referenced with GBIF occurrences.
What are the main threats to Large Marsh Grasshopper?
The main threats to Large Marsh Grasshopper are ai-1, ai-2, ai-3, and ai-4. The full IUCN-classified threat record for this species is detailed on the species page.
