This morning we headed to the Girvan catchment to see how our green engineering at Kilkerran was holding up. We installed several different techniques at Kilkerran to stabilise two massive erosion points that each stretched over 100m. At the time some suggested that the only way to address this was with rock armour and hard engineering but I think the results so far disprove that.
There has been a bit of erosion at Kilkerran and rather than leave this unaddressed, we will take steps to stabilise the two areas that need work. Both these areas are deep water and will require a slightly different approach next attempt. We will be working from a boat so watch for further updates.
Our fedges that link the livestock fence to the water’s edge have done very well and are now firmly established. They do require pruning as do some of the bankside trees but that was to be expected ad will encourage these plants to bush and thus further increase their effectiveness.
Despite these small set backs, overall, the work has been highly successful and 4 years after the original installation of spiling and willow faggots, the difference is night and day. The syndicate members are reporting that the number of trout within the beat is fantastic. I’m not surprised as the cover has improved tremendously and silt released from the banks has largely stopped which will help spawning areas downstream that were coated in fine sediment.
We will get to these repairs as soon as possible. One thing is for sure there’s no shortage of material available to work with and we will prune our fedges and willow trees to keep them in tip top condition.
If you wish to see more detail of this work from as far back as 2011, just search through our blog pages for Kilkerran, erosion and green engineering and you will be able to plot the history and transformation.
