Alt Eigheach Habitat Improvements Project Phase 2

23rd April, 2025

Restoring Spawning Grounds on the Alt Eigheach Burn

Protecting a Key Habitat for Salmon and Trout

With salmon populations in decline across Scotland, efforts are underway to improve spawning conditions on the Alt Eigheach Burn - a long tributary within the River Tummel system. A 2022 survey by the University of the Highlands and Islands recorded salmon fry in the lower reaches of the burn, confirming its potential as a spawning ground. However, a lack of trees along its banks has contributed to erosion, sedimentation, and rising water temperatures - factors that threaten the survival of fish eggs and juvenile fish.

To address this, small and large deer-proof enclosures are being installed along the burn. These are designed to protect newly planted native trees such as Alder, Downy Birch, Rowan, Hazel, Goat Willow, Scots Pine, Oak, and Wild Cherry. See compartment blocks in red below.

As these trees grow, they will:

1. Increase habitats for wildlife and invertebrates

2. Stabilise riverbanks and reduce sediment entering the water

3. Provide shade to lower water temperatures in summer

4. Support invertebrate life essential to the aquatic food chain

5. Help improve survival rates for Salmon and Brown Trout
