Silver Sedge

Odontocerum albicorne

Unknown

Overview

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

Odontocerum albicorne faces significant pressure from habitat degradation in its freshwater stream environments, particularly from agricultural runoff and urban development that alter water chemistry and sediment loads. Dam construction and water extraction for irrigation have fragmented its habitat and reduced water flow in critical breeding areas. Climate change is intensifying these pressures through altered precipitation patterns that affect stream hydrology and temperature regimes essential for larval development.

Threat summary

Habitat

This caddisfly species inhabits clean, fast-flowing freshwater streams and rivers with rocky substrates, typically in forested or semi-forested watersheds. The larvae require well-oxygenated water with specific temperature ranges and construct protective cases from sand grains and small stones.

Frequently asked questions

Why is Silver Sedge classified as Vulnerable?
Silver Sedge 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. Odontocerum albicorne faces significant pressure from habitat degradation in its freshwater stream environments, particularly from agricultural runoff and urban development that alter water chemistry and sediment loads. Dam construction and water extraction for irrigation have fragmented its habitat and reduced water flow in critical breeding areas. Climate change is intensifying these pressures through altered precipitation patterns that affect stream hydrology and temperature regimes essential for larval development.
Where does Silver Sedge live?
Silver Sedge occurs in Albania, Andorra, Austria, Belarus, Belgium, and Bosnia & Herzegovina (plus 28 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 Silver Sedge?
The main threats to Silver Sedge 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.
