The following lists are by no means exhaustive, but they are intended to act as a useful guide when selecting plants for specific locations, purposes and conditions.

When selecting trees, important factors to be considered are: 

- available space for the ultimate development
   of the trees
- soil conditions including compaction & drainage
- exposure
- light levels
- proximity to buildings
- services
- traffic

In addition, named cultivars rather than their common species are usually best chosen due to their more even & consistent shape.
