They use it to boast and rake in money. Or do you think they are putting out pictures of mountains in tourist publications so people won't come? Having hiked across Scotland on both the West Highland Way and the Great Glen Way I can confirm that many of the forestry practices (as the former Wildland firefighter that I am) would never fly in the US.
But then the two countries are so different in the aspect that they are almost impossible to compare. For instance the concept of wilderness areas does not exist in the UK as they do in the US. The UK is just too small. There are no area where absolutely no mechanised equipment is allowed to be used by Federal Law in the UK (ok, there is no federal government here). There is nothing like realising that you have to hump in 25 pounds of gear 10 miles and then trim and cut trees and maintain miles of trails with hand tools. No chainsaws, nothing that runs, only hand saws and loppers and no ride in or out.
The UK raped its native woodland ages before the US was a glimmer in the royals' eyes. That is one the reasons they wanted the US, trees for masts. You can still go to New England and find trees marked with the King's Arrow, a mark showing that the tree was owned by crown.
This is also why so there are so many more older/historic houses in the UK. After all, the US native population was around for a long time, but they built things out of the easiest materials available, wood. As did the settlers. Something that people in England didn't have access to.
Stone. It lasts a long time.
