25Results Recommendations
- 80 accurate for species, size, leaf condition.
- Less accurate for conflicts (66) maintenance
needs(49) due to training. - With more focused training, volunteers can
collect reliable data - Cover PDAs, maps, tree assessment in 6-hr day
- Separate 3-4 hour tree id session w/ dress
rehearsal - Slide library showing different management needs
- Demonstrate how to troubleshoot PDAs
- Cover street side safety tips
- Show key ways to distinguish most important
species
26Results Recommendations
- Organization use questionnaire to determine who
wants to survey trees in own neighborhood and
group together in training. - Develop formal troubleshooting process before
deploying volunteers so assistance is available. - Have refresher session soon after deployment to
review solutions to common problems.
