Possibly worth remembering: Iceland (and Greenland, where the vikings hung on until the fourteen hundreds) had significantly warmer climate a milennium ago.

Got any more reading for this? Just back from Iceland so I am interested in this stuff right now.

This is the only one I found, which doesn't seem to indicate a significant change.

I find quite interesting how we plan on terraform and colonize Mars when we can't even grow trees on Iceland.

In fairness, the article does mention several dedicated individuals; and who knows, they might inspire others - "many hands make light work".

It took a collective effort to remove the trees, makes sense that it should be like that to bring the forest back.

For reasons I won't go into the farming lobby is really strong in Iceland. Sheep run free-range around the entire island, if you'd like to grow something that sheep like to eat you need to fence it in. It's not like pretty much anywhere else in the western world where people who own grazing animals need to fence them in. Thus the sheep range far and wide and destroy Iceland's native low-lying forests. Iceland's nativ…

I agree, you'd have to carefully protect your trees until they reach a reasonable size that they can hold their own. Sheep will definitely prevent reforestation, although they are less likely than goats to harm saplings of a certain size.

The problem is that "carefully protect your trees" doesn't scale. And it's completely impossible for natural propagation, which is the only realistic way of meeting the goal of reforestation.

It's not just another devastated landscape of Europe, it's the single most naturally devastated landscape on the entire continent. The National Museum of Iceland in Reykjavík has a permanent exhibition on the subject that I highly recommend. Since colonization a little over a millennium ago most of the topsoil has been washed out to sea, wast swaths of the country that used to be fields or forests are now just bare r…

>it's the single most naturally devastated landscape on the entire continent. Isn't half of it technically on another continent?

No, half of it is on the North American continental plate, but those don't determine what constitutes a continent. If they did half of Japan would be in North America.

There is actually a similar problem in the Northeastern United States. Deer are overpopulated (in my area 6x traditional level) because they have no predators and hunting is restricted. The deer eat all of the hardwood saplings. In many mid-Atlantic forests there are very few 10-20 year old hard wood trees, they don't survive the deer.

And the deer overpopulation also contributes to the Lyme disease tick problem.

> As a result, Iceland is a case study in desertification, with little or no vegetation, though the problem is not heat or drought. About 40 percent of the country is desert, Dr. Halldorsson said. “But there’s plenty of rainfall — we call it ‘wet desert.’” At first I thought it was an error to call an area that gets plenty of rain a desert. I thought desert was strictly defined by the amount of rainfall. But maybe th…

The etymology of the word (think deserted island) would imply it has more to do with the lack of life than the reason for a lack of life.

Etymology of desert:

from Latin desertus, from desero (“abandon”)

From dē- (“away, from”) +‎ serō (“I bind, join”).

From Proto-Italic sizō, from Proto-Indo-European si-sh₁-, the reduplicated present of *seh₁- (“to sow”).

Maybe take an page from the Easter Islander playbook: Build vast networks of rock wall closed cells. Wind blowing over these will tend to deposit some of its soil. Bonus points if the walls are high enough to keep out sheep. ;-)

Plus, like with man-made climate change, more people are actively sabotaging the efforts. In this case by letting their sheep eat the saplings.

>> It's not like pretty much anywhere else in the western world where people who own grazing animals need to fence them in. It's an exception and not the rule, as you're saying, but I know of at least a few spots in the Rocky Mountains in the US where farmed cattle graze openly and property owners have to let them. The ones I'm thinking of I think became that way because it was a permanent condition of the sale of th…

Also I think throughout Montana there are free grazing areas for sheep. I think that's what you're seeing in the fantastic documentary called Sweetgrass: https://www.youtube.com/watch?v=AV9iah71iPQ
