We've recently updated this:

TAS Gov | QTRA to VALID Upgrade Explanation

It's because we've done some fine tuning to the Basic Validator guidance that's connected to it. We were also asked to clarify some of the points in it.  Here's the text from the original post.

As some of you are aware, the Tasmanian Government (State Roads) was an earlier adopter of VALID’s approach to tree risk-benefit management and assessment.

They’ve completed their move to a VALID Strategy from July. Basic Drive-by Assessments are carried out in high use zones as part of their 5 yearly Active Assessment programme.

One piece of work they asked us to do in this project was write a short briefing note for the General Manager State Roads, Department of State Growth (DSG).

The briefing note is to make the case for and explain why they were upgrading their approach from QTRA to VALID.

We’ve not shared this before because we thought it was a confidential bit of in-house work for DSG’s tree risk framework review team.

However, it turns out it's not confidential because the DSG is a government agency. The work is in the public domain.

As many of you working at the tree risk coalface might find it of interest, we’re now sharing. and you can download it here:
