Tree warden school

Each fall, the Tree Wardens' Association of Connecticut conducts the Tree Warden School.  This seven week course located in New Haven is held on Thursday mornings from 8:30-12:00 (dates and location subject to change from year to year). Attendance is required at 6 of the 7 classes and a passing grade of 70% on the final exam. Tree Wardens and Deputy Tree Wardens are given top priority on open spaces for the next session, but anyone is welcome to apply to Tree Warden School. The schedule is updated in the spring. Any questions regarding Tree Warden School should be directed to the office.

The TWAC holds two educational workshops per year; once in the spring and once in the fall. The locations of these workshops are rotated around the state. Continuing Education Credits for Tree Wardens and other professions are always offered. Be sure to check out the Events page for upcoming workshops. Events are open to members and the public.

municipal tree care academy

Providing municipal employees with the skills and foundations to care for a healthy, safe, economical, and productive urban forest.

The Municipal Employee Tree Care Academy is a hands-on certificate training course offered by the Tree Wardens’ Association. The course subject matter, location, and timing can all be tailored to meet the needs of your municipality. Employees will be awarded a certificate upon successful completion of each training topic. Instructors are Connecticut licensed arborists with many years experience working in municipal forestry and urban tree care.

As the urban, rural, and roadside forests of Connecticut continue to mature and die-off, there is more need than ever for new tree plantings. Regular care and maintenance of new and young trees by TRAINED employees will result in a healthier, safer, and more cost efficient urban forest. A young tree that is properly planted, watered, mulched, and pruned will grow to be a long lasting member of your community’s forest that will require less inputs down the road.
