    This website is a virtual arboretum, created for interest, education and beauty. It exhibits some of the thousands of trees, of both native and exotic species, that grow in Whiteknights Park, the main campus of the University of Reading. Many of them have been planted since the university arrived in 1947, but some have been here since the 19th century or earlier, when Whiteknights was the gardens and parkland of large houses. Nine of the trees are listed as the British Isles champions of their species in The Tree Register.
