Every year we have a gurn about the amount of Japenese Knotweed growing along the River Nairn and particualarly in the town centre area. Hoping perhaps that one day the local authority will take it seriously. It not only squeezes out native species but it can also seriously damage property values it seems:
Could it happen in Nairn? Well the clumps of Knotweed seem to spread very quickly each season and apparently it takes a 3-4 year period of treatment if you want to dispose of it. So perhaps it's time to get seriously started on this stuff when it pops up again in the spring?
