A raised bog in West Lothian, Tailend Moss lies 2 miles (3 km) east southeast of Bathgate and 2½ miles (4 km) west of Livingston. It represent a wetland underlain by a deep accumulation of peat, which has formed over thousands of years. Relatively rare in the Midland Valley of Scotland, where much of the peat was removed to drain the land for agricultural use, Tailend Moss is protected as a Site fo Special Scientific Interest (SSSI), designated in 1988. Extending to 30.2 ha / 74.6 acres, it supports plants such as heather, sphagnum moss, bog asphodel, cranberry and sundews, and is an important site for damselflies and dragonflies. A number of bird species have been recorded including curlew, finch, kingfisher, oystercatcher, tit, wagtail, warbler, wildfowl and small raptors.
The reserve is managed by the Scottish Wildlife Trust, and an access path runs along its northern edge.
