Purple Moor-grass

The torn grasses which last week storm Eunice chased across the heathland, now clog the puddles and seasonal ponds on the plains. The grass is Purple Moor-grass (Molinia caerulea) a native species common on wet acid soils like the New Forest; though I understand that due to changing climatic and environmental conditions the grass is now out performing and choking it's fellow heathland floral comrades, with the potential to change the nature of the heathland; that would explain it's abundance. Not good.
