People with an interest in orchards have joined a team of experts to examine an impressive example in the Carse of Gowrie.
As part of the Tayside Biodiversity Festival and coinciding with the Scottish Biodiversity Week informal tours of Megginch Castle orchard and walled garden have been held.
They were led by lichenologists John Douglass and Peder Aspen, who pointed out the lichens living on the veteran fruit trees.
Another expert, David Bell, of Abernethy, identified plants, insects and birds and explained the variety of wildlife that use orchards from bats and badgers to hares and voles.
The festival runs until the end of the month.
