There are two kinds of litter in this photograph. The beer bottle, which is no longer there, and the Asparagus "Fern" which is likely to thrive. Asparagus aethiopicus is a native of South Africa, and a very threatening escapee from ornamental gardens. When it gets going it smothers all native seedlings.
I wonder whether I'll get into trouble if I just march down with my garden fork and solve the problem in our dunes?
