Standard Tree Evaluation Method - STEM™

Standard Tree Evaluation Method - STEM™

Following many years of collaboration and development from various stakeholder groups in New Zealand, this tree evaluation method was first published in September 1996 by Ron Flook.  It quickly became the most widespread method of evaluating heritage and notable trees for district plans around the country.  It is now used by more than 40 Councils in New Zealand. See the author's note.

In August 2012 the New Zealand Notable Trees Trust became the copyright holder of STEM™.  The NZNTT is indebted to the Flook Family for allowing the Trust to become the new home and controlling authority for this valuable tool.

STEM™ scores can be entered on records for trees listed on the New Zealand Tree Register.  This enables the benchmarking and comparison of trees around the country.

Copies of the publication can be purchased directly from the Trust.
