It is slightly unfair to say there's barely an ecosystem. If all you've seen is Reykjanes between Keflavík and Reykjavík then sure it might look like a bleak, moss covered, rocky desert. But the thing is that different regions can vary quite drastically in their level of vegetation. You might have farmland on one side of a mountain but on the other side a vast sandy desert.

But, to be fair, if your measure of a fertile landscape is a forest then those are relatively few and far between. Personally I tend to feel a bit claustrophobic when there are trees boxing me in on all sides and I can't see the mountains. :)
