Schematic/crest of 3 shields of the Grey Squirrel (Sciurus vulgaris).
Originally imported from America to Great Britain ca. 1840 as a living lawn ornament. On left, the nationalist  imperative that the Greys should now be exterminated; on right; deforestation in part to supply the Briitsh Royal Navy with timber historically contributed to the near-vanquished Red Squirrel’s loss of habitat, helping to pave the way for the victorious Greys.
