Flora of Cornwall (1999)

The descriptive text, below the map, is from the Flora of Cornwall (1999), which was a Tetrad Atlas (the maps had 2km square dots or Tetrads). The map on this web page depicts the plant's distribution at the 1km square scale and shows the records made pre-2000 which were used in the 1999 Flora and those made since.

Cynodon dactylon - Bermuda-grass

The recent construction of sea defences at Longrock initially reduced the population of Bermuda-grass, but it has recovered well and the sandy banks between the railway and the beach, from Eastern Green to Marazion remain its Cornish stronghold (SW43V & SW53A). This Red Data Book plant can also be found within the inner harbour at Portreath and on sandy banks by the river, where it is much reduced. The creation of flower beds in the outer harbour of Portreath (SW64M, 1994, C.N. French) demonstrated that this can be a pioneer species. After the bedding plants, which were not salt tolerant, had died, these flower beds rapidly filled with Cynodon before Festuca rubra took over. Bermuda-grass has been searched for at Hayle (SW53N) but not refound, and it is not known whether it remains at School Green on Tresco, Isles of Scilly.
