This list is undoubtedly enhanced by the presence of a high proportion of non-native species which have originated in nearby gardens or may possibly have been transported as seed some distance for example by birds. In particular, the northern edge of Lords Bushes has a number of introduced tree and shrub species, many of these including plum (Prunus domestica), cherry (Primus avium) and lilac (Syringa vulgaris) appear to have originated as suckers from the parent tree or bush in the adjacent garden. The burnt and disturbed area has provided some notable records, in particular the abundance of small trees of goat willow (Salix caprea), a species noted often as an early coloniser of waste sites, and similarly a number of buddleia (Buddleja davidii) have appeared on the area. Sycamore (Acer pseudoplatanus) occurs only in a relatively small area on the Knighton Land side of the undisturbed woodland (bar a solitary seedling found on the burnt and disturbed area) on ground possibly cleared originally in the nineteenth century, following gravel extraction. Mountain Ash (Sorbus aucuparia) is not common as a mature tree but well distributed mainly on the margin of Lords Bushes and in the old gravel workings. It is traditionally considered to be an introduction in Essex, though many trees undoubtedly arise from bird sown seeds, as no doubt have the seedlings of this species found on the burnt and disturbed area. Swedish whitebeam (Sorbus intermedia) is to be found only as a single mature standard N.E. of pond P2; this tree has undoubtedly given rise to the seedlings found on the burnt and disturbed area. Ash (Fraxinus excelsior) likewise is to be found only as a single mature tree on the Knighton Lane edge of Lords Bushes it is a tree incompatible 30
