Whether it lasts 20 years, 100 years or thousands it changes the world for the long haul. This simply shows that we can in a clear cut demonstration covering some real history. It may be that to get best affect you want it to die off in just decades. Or maybe it will be good for 100 years. This simply shows the long term power under some conditions. And this may have been forested in the mean time so what you are actually seeing is generations of tree roots taking advantage of that little better moisture and in the process adding their own material to the longevity of the process. But any way you look at it this isn't a short term fix.

The henges are actually a series of concentric circles created by placing large posts in the ground. When the henge fell out of disuse or was burned down, the underground portions of the posts rotted away, changing the composition of the soil in the posthole, causing it to retain more moisture. During a drought, while the surrounding crops yellow, the plants over the post holes have a slight advantage.
