Project summary

Edit project overview to modify the project summary.

River restoration works have been carried out along a high-energy reach of the River Avon within the River Spey Special Area of Conservation (SAC) in Cairngorms National Park. The project encompasses green engineering woody structures and sediment management, as well as water margin management and riparian planting. The aim is to improve the capability of the watercourse to cope with high flow events, reduce excessive erosion and to protect in-channel and riparian habitats, as well as farm livelihoods and infrastructure. The works were carried out as a Scottish Rural Development Programme (SRDP) Agri-Environment Climate Scheme (AECS), supported and managed by a National Lottery Heritage Funded partnership (Tomintoul & Glenlivet Landscape Partnership) as part of their wider ‘Our Water Environment’ project running across the Tomintoul and Glenlivet area.

Monitoring surveys and results

This case study hasn’t got any Monitoring survey and results, you can add some by editing the project overview.

Lessons learnt

Edit project overview to modify the lessons learnt.

Cash flow is an issue as sizable sums required up front – project partner supported cash flow but the project could have been wider-reaching without this problem.

Significant up-front investment is required to carry out initial survey work required to be able to inform land owners / managers about risks involved and allow them to decide if this is something they can accommodate.

Lack of understanding about green engineering techniques means significant engagement is required early on to gain buy-in & permissions.
