kysthakeedderkopp

Trichoncus hackmani

Unknown

Overview

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

Trichoncus hackmani faces significant pressure from coastal development and infrastructure projects that destroy its specialized dune and sandy shore habitats along Scandinavian coastlines. Climate change poses an additional threat through rising sea levels and increased storm intensity, which can flood or erode the species' preferred microhabitats. The spider's limited dispersal ability and highly specific habitat requirements make it particularly vulnerable to habitat fragmentation and local extinctions.

Threat summary

Habitat

This specialized spider inhabits coastal sand dunes, sandy beaches, and maritime grasslands along the shores of Scandinavia, particularly in Norway and Sweden. It requires loose, well-drained sandy substrates with sparse vegetation where it can construct its characteristic burrows and hunting grounds.
