Management decisions grounded in ecological understanding are essential to the maintenance of a healthy urban forest. Decisions about where and what tree species to plant have both short and long-term consequences for the future function and resilience of city trees. Through the construction of a theoretical damage index, this study examines the legacy effects of a street tree planting program ...

This suggests that much can be learned from the...

The importance of soil factors to the establishment of tree crops is well recognized by forest soil scientists and foresters. It has, however, been overlooked by far too many foresters responsible for major forestation projects. The soil factors found to be significant in the establishment of both planted stock and seedlings from natural or artificial seedf all are: texture and structure charac...
