Endemic species are found in a single defined geographic location, such as an island. We try to figure out of the Watershrew (Neomys fodiens) found on Texel island, can be considered as an endemic (sub)species.
On Texel Island, competition between the water shrew and the invasive white-toothed shrew (Crocidura russula) is contributing to the decline of the water shrew. The white-toothed shrew, a generalist species, is better adapted to varied habitats and often thrives in areas modified by humans, such as farmland and urban edges. It competes with the water shrew for resources like insects, spiders, and small invertebrates. The water shrew, which requires clean, aquatic habitats, is more specialized and sensitive to environmental changes. The invasive species outcompetes the water shrew through its adaptability and higher reproductive rate, further displacing it. To protect the water shrew, efforts must focus on preserving aquatic habitats and limiting the spread of the white-toothed shrew in key areas.
Further we help by updating the distribution data of the endemic species in different areas of conservation on Sri Lanka. Such as the purple-faced langur (Semnopithecus vetulus), the Layard’s Palm Squirrel (Funambulus layardi), the Sinharaja White-toothed Shrew (Crocidura hikmiya) and the Sri Lankan Woolly Bat (Kerivoula malpasi). Updating the distribution data of endemic species in Sri Lanka can help conservation by identifying critical habitats and tracking population trends. Conduct regular field surveys using modern techniques like GIS mapping and citizen science apps to gather accurate, up-to-date data. Collaborate with local communities, researchers, and conservation organizations to monitor species in protected and unprotected areas. Share the data with policymakers to guide habitat protection, restoration, and sustainable development. Improved data enhances conservation planning, prioritizes areas for action, and ensures targeted measures to protect Sri Lanka’s unique biodiversity.
