Tree Risk Assessment

[Acer ventura]

Thought this might be of interest to some of you.  It’s an updated and improved version of a Tree Risk Assessment review article that’s going out in this week’s NZ Arb’s Tree Matters, and was in Australia’s Arbor Age last month.

I’ve made some alterations to the text and images to what’s going to be published so it's a better reference document.  Mainly so the images are arranged closer to the point in the text where they’re discussed.  I’ve also updated the App screen grabs to make them current.  They include the people icon at the bottom right which lets you work out whether the combination of traffic and people means the occupancy should be one category higher.  In this case, if you include people is the likelihood of occupation 1 Very High instead of 2 High?

Nice debunking of the matrix approach; "Anything is Possible" so it can be worse than useless.

 

Also it's not clear that we need to pretend that we can reliably calculate Likelihood of Failure.  It seems like we're chasing a ghost when we try.  At best it's a SWAG, but typically we are at a high risk of misleading our clients.

 

Honesty might really be the best policy.

Never too confident of such ( or any systems ) as laziness on the practisioner can be fatal to the systems integrity . Sometimes a good teeth sucking an a fag can let you see more , K
