RSPB Scotland has resumed a controversial cull of feral goats on the eastern shore of Loch Lomond.
The environmental organisation is facing criticism from local people, who fear the cull could wipe out the entire population of goats around Inversnaid.
But their voracious appetites cause problems for conservationists and RSPB Scotland says it needs to protect the rich woodland habitat.
It wants to reduce goat numbers in the Inversnaid area from about 69 to 30 in the coming years.
Reserves manager Robert Coleman said: "This is Scotland's rainforest. We've got a huge range of moss and lichen here. In fact, 5% of all of the world's moss species are represented in Scotland and this habitat is an excellent example of that diversity.
"By managing the herbivores, deer and goats, we can ensure the longevity of this habitat and make sure there are trees, mosses and lichens in the future while ensuring we maintain the populations of herbivores within the area as well."
