Overview

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

The bog turtle faces severe population decline primarily due to wetland habitat destruction and degradation from agricultural conversion, urban development, and altered hydrology. Illegal collection for the pet trade has historically decimated populations, while invasive plant species and sedimentation from surrounding land use changes continue to degrade remaining bog and fen habitats. Climate change poses an additional threat by altering precipitation patterns and temperature regimes critical for maintaining the specialized wetland conditions this species requires.

Threat summary

Habitat

Bog turtles inhabit small, shallow wetlands including sphagnum bogs, sedge meadows, fens, and marshy areas with soft substrates and emergent vegetation. These specialized habitats require specific hydrological conditions with slow-moving or standing water, open canopy areas for basking, and adjacent upland areas for nesting.

Frequently asked questions

Why is Bog Turtle classified as Critically Endangered?
Bog Turtle is classified as Critically Endangered — facing an extremely high risk of extinction in the wild — because population sizes are very small, declining sharply, or restricted to a tiny range. The bog turtle faces severe population decline primarily due to wetland habitat destruction and degradation from agricultural conversion, urban development, and altered hydrology. Illegal collection for the pet trade has historically decimated populations, while invasive plant species and sedimentation from surrounding land use changes continue to degrade remaining bog and fen habitats. Climate change poses an additional threat by altering precipitation patterns and temperature regimes critical for maintaining the specialized wetland conditions this species requires.
Where does Bog Turtle live?
Bog Turtle occurs in across multiple regions. Country-level distribution data is sourced from the IUCN Red List and cross-referenced with GBIF occurrences.
What are the main threats to Bog Turtle?
The main threats to Bog Turtle are 1.1, 1.2, 11.1, and 2.1. The full IUCN-classified threat record for this species is detailed on the species page.
