Whilst clearing the thistles, nettles, long grass and fast-spreading Himalayan Balsam, we've found some Tansy plants.
Big deal, you might think?
Fortunately our eagle eyed friend from York council, Jenny, educated us on it's significance. The Tansy plant is home to the declining Tansy Beetle, which only lives in the UK along a limited stretch of the river Ouse. Hence, we've unintentionally become conservationists since by clearing the competing weeds and leaving the Tansy plant to thrive, we should hopefully help create more habitat for the Tansy beetle.
