risk tree rating system is essential to ensure that appropriate
and reasonably consistent criteria are used to evaluate
the relative hazard of a tree. Using a rating system allows
for the systematic prioritization of risk tree removal and
enables the development of realistic fiscal budgets needed
for their removal. Many rating systems are available for
use, based on the specific land-use or landscape setting.
For example, the identification of potential hazard trees
along a rural roadway is quite different that examining
trees in a park picnic area. Methods and criteria for ranking
risk trees are different in each setting, and the ability
t accurately complete assessments in these locations varies
in many ways.
The method that you use to evaluate
the condition of trees under your jurisdiction will be adapted
to your specific situation. Several model evaluation and ranking
protocols are provided here for your use. These represent only
a baseline evaluation, and the forms should be modified to suite
your specific setting and situation.
