The last convening of the Regional Plant Appraisal Committee (RPAC) back in 2007 resulted in the publication of the Species Rating guidebook. If you haven’t purchased a copy of this tiny gem I believe there are still literally boxes of them available for sale through the chapter office. (Seriously. It’s time to reconvene.)
A lot of things in the plant appraisal world have changed since 2007. Most notably, the publication of the 10th edition and the roll-out of a Tree and Plant Appraisal Qualification (TPAQ) by ASCA.
In the year and a half since the Guide for Plant Appraisal,10th Edition hit the shelves several classes of the TPAQ have been held. With much interest from the arborist community to fully implement the 10th Edition, it’s imperative that we reconvene the RPAC. Our goal will be to publish an updated Regional Plant Appraisal Guidebook. This will allow for full usability of the 10th Edition.
The RPAC will gather data from around the region for current costs associated with planting commonly available nursery trees. We will also update individual species ratings to align with functional depreciation factors. This will allow for accurate and defensible cost method appraisals.
For this to work well, we need representation from the different geographical areas of our chapter.
We’ll likely be using the Sunset climate zones as a resource to determine species ratings and other depreciation factors. Ideally, we can find committee members from each of the 14 different climate zones ranging from Alaska to Oregon. We would like to populate the committee with arborists, foresters, landscape architects, public servants, university staff, and nursery folks. We’ll be asking for potential committee members to demonstrate their competency with plant appraisal by submitting a copy of their work.
Our aim is to have the regional guide debut in October 2020 at the next Annual Training Conference in Coeur d’Alene, Idaho. The plan is to make this a dynamic guide. We should be able to update pricing on a regular basis as well as having the ability to change species depreciation guidelines as needed.
