I have slightly changed the first sentence to define Alvar as an ecosystem rather than just a physical environment, which is in keeping with the rest of the article. Its usage to describe a karst landform is not reflected in most karst terminology glossaries (and none of the on-line ones). I have also removed the sentence regarding poor drainage and springtime flooding, as this is not typical of some of the alvars cited in the article nor of the karst pavements of Britain and western Canada, which tend to be perched and drain quite well.

[edit] Photos
I am taking the liberty to replace the view of Kelley's Island; it's not a good photo, and it's mostly a forested shoreline. (I seem to recall that the Great Lake alvars are less open than those of Europe, so a better photo would be nice!)
Replacing it with my own from Kinnekulle. If anyone has one from Öland that'd be better; my photo shows the exposed limestone slabs, but not the vast, almost treeless plains of Öland's alvar.
Also adding another picture (complementing the existing Kelley's Island photo) showing sparse vegetation typical for thin-soil, springtime flooded, alvars.
