The Dutch root vole (Alexandromys oeconomus arenicola) is the only endemic vertebrate found in the Netherlands. Mainly studied by us on Texel island but also elsewhere in Noord-Holland and, like in 2022, on Goeree-Overflakkee, Commissioned by the Dutch Mammal Society.
The Dutch root vole faces significant threats. Habitat loss is a major concern, caused by wetland drainage, agricultural intensification, and urbanization, which reduce and fragment its living spaces. Fragmentation isolates populations, making them more vulnerable to extinction. Water management practices, such as fluctuating water levels, often degrade suitable habitats, while climate change poses long-term risks by altering wetland ecosystems. In addition, the arrival of the field mouse and the earth mouse, with the help of human action, increases the competitive pressure and causes a decrease in the population size. This in combination with the already mentioned decrease in water level dynamics due to our water level management.
To preserve this species, protecting and restoring wetland habitats is essential. Sustainable water management practices must ensure dynamic water levels to strengthen competitiveness. Establishing ecological corridors can reconnect fragmented populations, improving genetic diversity and resilience. Monitoring and managing competing species is also crucial. Conservation efforts should include long-term research with tagged animals to better understand the vole’s ecological needs and threats. Public awareness campaigns can foster support for conservation actions, while collaboration between landowners, policymakers, and conservationists can ensure effective, sustainable measures. Protecting the Dutch root vole contributes to preserving the unique biodiversity of the Netherlands’ wetland ecosystems.
