The Beat is an avenue of London plane trees and some Horse Chestnuts, funded by every Police Force in the UK. Chestnuts were chosen because the first truncheons were made from this extremely durable wood.

 Visitors to the Chapel will be struck by the twelve pillars of Douglas fir, Pseudotsuga menziesii. Construction of the Chapel began in 1999, the 200th anniversary of the birth of Scottish plant collector, David Douglas. Between 1825 and 1827 he travelled a staggering 10,000 miles in Western Canada and North West USA on foot and by canoe, collecting and classifying plants. As a result of his efforts, 200 new plants were introduced to the UK, including the Douglas fir.

Six Dawn redwoods,Metasequoia glyptostrobides, can be found on the Ambulance Service plot. These magnificent trees, identified as a ‘living fossil’ in 1941, once blanketed the entire Northern Hemisphere and were thought to be extinct by Western botanists until their rediscovery in 1941 in the Szechuan Province of China.

Of the 33 truly native species found in Great Britain, such as the Black poplar, Populus nigrassp.betulifolia, and Strawberry Tree, Arbutus unedo, 32 can be found at the Arboretum. The only one missing is Wych elm, Ulmus glabra, which died as a result of Dutch Elm Disease.
