Rowan is an important species in Alladale’s birch and pinewoods. It is a fruit producing tree that produces berries in the Autumn and is therefore an important source of food for birds and invertebrates.

Water voles were once Britain’s fastest declining mammal, but the Reserve is home to a thriving population of water voles. Signs of water voles can be seen across the bottom of Alladale’s glens, along the Alladale and Abhainn a’ Glinne Mhoir river, as well as smaller streams and burns.

Downy willow is one of few true montane willows, and so it only grows above altitudes of around 650m. In 2022, a significant population of downy willow was discovered on the steep cliffs above Lochan Pollaig in Glen Alladale.

The kestrel is one of the most frequently sighted birds of prey, with several nesting birds on the reserve.
