What’s it worth? Tree valuation methods in the UK

[AA Teccie (Paul)]

With a growing number of methodologies for putting a value on trees there is growing debate about which is best, which is most appropriate and which one to use in which situation.

'What's it worth' is an Arb Association workshop day that will look at the four main ways of valuing amenity trees. A first for the UK - the workshop will bring together the key experts and proponents of each system whose knowledge and understanding of their respective methods cannot be matched.

• The Helliwell system - Rodney Helliwell

• CTLA - Adam Hollis

• CAVAT - Chris Neilan

• i-Tree - Kenton Rogers.

Each presenter will describe the relevant system and explain its origin and intended application, with opportunity for questions and discussion. Each presenter will also value two "example" trees using their system so a direct comparison can be made and the intricacies of the differences between them can be explored.

 

Venues in Berkshire (14 July), Somerset (29 September) and Warwickshire (13 October) can be booked by clicking here and scroll to ‘What’s it worth?’.

Errr.. You seem to be minus a link.

 

I've been to talks on all of those systems, other than the CTLA, and worked with CAVAT. It will be interesting to see them directly compared - and contrasted - with each other at the one seminar.

 

For anyone involved in tree management or working for LAs, I think that will be a very worthwhile day.

 

 

 

 

I've added the days into the AT calendar, so there's no excuse for forgetting these dates now.
