Our Bronze Age legacy....a beautiful butterfly.
But this little three hectare patch of land now known as Seven Barrows (even though there are nine) is one of the very few places in the UK where the beautiful butterfly can now be found - and the reason is the Barrows themselves. They're ancient burial mounds (one grave alone was found to contain the cremated remains of 100 individuals dating from 2200 BC!) and because they make it impossible to plough the land, they've always been impossible to farm.
Which means the habitat has been kept more or less intact for thousands of years.
That's important for the (wait for another fantastic name...) Devil's-Bit Scabious which is a small wildflower with purple-blue pincushion-like flower heads - and is the foodplant for the Marsh Fritiliiary.
So thanks to those Bronze Age mounds, we still have a beautiful butterfly which would otherwise have disappeared from Berkshire forever. For more on this, have a look at BBOWT.
