Exhibiting

The declining flora of Cornwall.

This exhibit extends the analysis, in the recently published Flora of Cornwall book, of the native and archaeophyte flowering plants and ferns that were more widespread before the year 2000. This is achieved by hotspot mapping the occurrence of declining taxa as a whole, hotspot mapping places where declining plants have not been seen since 1999 and by using Ellenberg values for reaction, moisture and light to assess what groups of plants have been most prone to decline.
