Teazles used to be very common in the scrubby areas by Anglers Walk. In one field, they were so common it looked like they had been planted as a crop, albeit one densely surrounded by nettles and more. During the flowering season they attracted lots of insects, especially bees.
That field is the one chosen as the site for the ponds and scrapes of the new nature reserve. Most of the teazles went in the process. But a few do stubbornly remain, and still attract bees to their flowers.
