Richard Jeffries and Roy Richardson Improving Scottish Rivers Proposals for delivery
From this… Urban improvements …to this.
From this… Rural improvements …to this.
River corridor Agricultural field Varied habitats – trees / scrub Flood water storage within river corridor Good for Ecology Good for land management Varied habitats – pools, riffles, etc Natural width low-flow channels keep the river bed clear of fine sediment. Less maintenance needed.
Catchment plan Healthy rivers Ecologically unhealthy
Ecology Land use Urban Healthy sections Unhealthy sections Area at risk of flooding Focus areas Urban areas - flood risk? Land use River corridor Urban area Arable – avoid Pasture – investigate potential River corridor
Local factors & opportunities Channel moving around – issues with drain maintenance Regeneration opportunity Possibility of small-scale works 2 metre statutory buffer Space for a functioning river High value land: no restoration here Possibility of small-scale works
River plan Ecology Land use Urban Stepping stone restoration Less maintenance Better habitats Restore to reduce flood risk No change Stepping stone restoration No change
Rural restoration opportunity • Land not used for agriculture • Old channel still present
Logie burn • £22,000 from SEPA • Total value £48,000 low cost active restoration

Discussion questions • Is improvements based on constraints the right approach? • Improvements: where might benefits outweigh costs? • Constraints: where might costs outweigh benefits?
