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.

Alnus incana - Grey Alder



Grey Alder seems to be a fairly recent introduction to Cornwall and has been planted in a variety of places. These include mine waste at Wheal Maid, near St. Day (SW74L, 1995, C.N.French), near Doublebois Quarry (SX16X, 1997, R.J.Murphy) and in a tree planting scheme on china clay waste at Carclaze (SX05C, 1997, M.Atkinson).
