Declining trees in small soil space
Roots
on healthy trees quickly fill the soil space within small parking lot islands
or narrow median strips (right photos). If roots are unable to escape the island
then the tree can begin to decline due to lack of soil resources (bottom left photo
- note dieback in the tops of the trees). Growth typically slows in the years
prior to dieback symptoms in the canopy. Health is not likely to return to these
trees because they have simply run out of soil space. Trees in many regions grow well without these symptoms for 15 to 20 years only to show decline soon after.
