They link small remnants of the ancient Caledonian pinewoods which once dominated Scotland's landscape.
NatureScot estimates that about 800,000 trees have been planted and although most are Scots pine the woodlands also contain birch, holly, oak, rowan and aspen. The final 20,000 locally grown trees will be planted out in Glen Torridon towards the end of the year, after which the reserve will be left to grow and expand without human interference.
Many of the species will take hundreds of years to grow to maturity meaning it will be for future generations to experience the vision for Beinn Eighe.
Planting trees, with the best will in the world, doesn't replicate the natural evolution of a woodland.
Woodland that regenerates of its own accord is much more species rich, much more structurally diverse, which provides a greater range of niches for a greater range of species.
Much of the site's ancient temperate rainforest was felled during World War Two to supply timber as part of the war effort.
