Tennessee Arboretum Certification Requirements & Levels

 

General Requirements

  • Accurately identify at least 30 distinct  tree species.

  • Meet criteria for Level 1.

  • Location must be open to the public. Special consideration for private sites is available.

  • Trees are and will be maintained in good health.

  • Protect trees from string trimmer and mower damage (through communication with maintenance, markings, mulch or protection device).

  • Mulch, if used, must not touch the tree’s trunk.

  • Newly planted trees must must be watered on a regular schedule.

  • All trees are to be labeled with both their scientific/botanical and common names.

  • Tree labels must be  easy to read and located near tree.

    • Place tree labels on or directly adjacent to each tree. Staked tree labels are preferred; however, tags can also be hung from limbs or embedded in trunks using aluminum nails or screws at a readable height. Steel screws or nails are not recommended. Spacing-springs are optional, but need to be placed in front of the sign

  • Trees located within or overhanging high-use areas must be in safe condition and inspected regularly for potential hazards.

  • If a tree poses a safety risk, then corrective actions must be taken.

  • The TUFC Certified Arboretum sign must be posted and maintained.

  • Re-certification is required every 3 years.

The following are encouraged:

  • Use an ISA Certified Arborist to inspect all trees in accessible areas before applying or re-applying.
