5 steps of a site evaluation
- Above ground site attributes
- Below ground site attributes
- Potential site modifications (which may have occurred)
- Maintenance practices
- Desirable attributes
prior to planting?
- look for indicator species.
- evaluate the surrounding area.
- look at other trees to assess what conditions may be like.
