Tree Risk Training

What's in it for you?

Tree risk management and assessment can be really challenging and confusing, can’t it?

Well, the great news is it needn’t be.  We've done most of the hard work for you, behind the scenes, with a Professor in risk of the natural environment and the risk modelling.  Then taken out the bafflegab (vague words) and numberwang (difficult maths) from tree risk so it's clear and easy to understand. If all that wasn't enough, we've even written your Tree Risk-Benefit Management Strategy for you.

If you're assessing tree risk, the Tree Risk App and Validator Strategy you're trained to use does a lot of the heavy lifting for you and your clients.

One of the things you’re going to love about upgrading to VALID is how much more user-friendly you’ll find it.  Whether you manage tree risk, or carry out tree risk assessments, you're about to discover that it's going to get a lot less complicated and a lot more effective.

Don't take our word for it, look at what they're saying on the right.

Once you've moved ahead with VALID, these are some of the words you'll use to describe how you feel about it.

"Uncomplicated...intuitive...simpler...clearer...smarter".
