Are Scotland's islands and highlands a desert?

We have lost 99% of our native Scottish woodlands in the past 5,000 years: and I argue that this mistake can and must be remedied.

Here’s a decent video analysis - that explores the lost landscapes of Scotland, the surviving relics of ancient woodlands, and maybe offers hope for the future.
Causes of this massive deforestation include
1: Logging for wood - for fire and building materials.
2: Clearing for pastureland and rough grazing for sheep and cattle
3: Hunting of deer
4: Highland clearances
In some respects the Highlands now have very low economic output - adventure tourism, a bit of marginal grazing, a bit of hunting, shooting, and fishing - but even the wild salmon have largely deserted these wild lands. This mirrors what is still happening today in places like Brazil, Borneo and the Congo - the land is plundered, and then people desert it and move on.
Can Scotland ever hope to regain the past glory of major pine and aspen, oak and beech, blackthorn, birch, hawthorn and rowan?
Can we restore the apex predators: lynx, bear, wolf, beaver and fox? And the great eagles, owls, and harriers ? Can our rivers run with salmon again?
I would argue that we can and must: and what is more, this can be achieved within a couple of generations. It is simple: it relies only on the will and vision to make it happen.
