Japanese Knotweed (Reynoutria japonica)

Just across the pasture, south west from the old Guisachan House ruin is a short steep sided river gorge running to Guisachan Fall, known locally as Home Falls, and just short of the forest road to Plodda Falls and Cougie.

About a hundred metres in from the house end a patch of Japanese Knotweed has become established on the path side of the river.

Japanese Knotweed is a terribly invasive alien introduction from Japan which spreads rapidly to completely dominate large areas and is a member of the Dock family.

This patch is now spreading up the southern side of the gorge as well as along the river bank in both directions.

Below are images of this patch in winter and in late August when it is flowering.

This web site is about the wildlife, particularly the mammals, of the Glen Affric National Nature Reserve area in the north west Highlands of Scotland, UK; and the equipment I use to search for them, which is chiefly trail cameras.

I provide a technical support and parts service for the Ltl Acorn range of cameras and the income from this provides for the upkeep of this site and the purchase of cameras for my own surveying.

I hope you find the site useful and informative; and please contact me if you have any questions that I haven't already covered.
