Tree age definitions (tree surveys)

[twigger]

Out of interest, what were the four fungal examples?

 

Good luck with the outcome

Thanks!

 

We had (excuse spellings, am doing this from memory) polyporous squamosis, phaeolus schweinitzii, inonotus hispidus and p(?) pomaceus.

Were the annual fruit bodies of the first three fairly desiccated or relatively fresh?

 

Last one would be Phellinus pomaceus

 

Which resources were you able to use for the open book test?

The polyporous squamosus was fresh and clear to see what it was. The phellinus pomaceous (thanks! knew it started with a P) was relatively easy to work out. The innonotus hispidus was black, and the phaeolus s.. didn't look much like it did in the book.

 

Each sample was given with a piece of paper saying what species of tree it came off (latin name). We could use any resources we wanted - anything we had brought with us, and anything that Guy had (he had brought some books). I used the AA book and some of my own notes.

we had the first 3 - I bet Guy is going to have to totally change his fungal examples after this thread lol

 

Sorry Guy

Ahhhh but it could be a bluff / double bluff - people will not expect the same ones now!

Here's what I use, and I am certain that I derived it from a reliable source.

 

Newly planted Not fully established and capable of being transplanted or easily replaced

Young Establishing, usually with good vigour

Early mature Established, usually vigorous and increasing in height

Mature Fully established around half their species’ life expectancy, generally good vigour and achieving full height potential but crown still spreading

Late mature Moderate vigour, no additional height expected and growth rate slowing

Over-mature Fully mature, in last quarter of life expectancy, vigour decreasing

 

But I would suggest you don't just copy it or anyone elses' definitions. Life stage is linked to vigour, potential for further upward growth, further outward growth, the onset of fruiting, the annual number of leaf flushes, degrees of susceptible ripewood or heartwood, step change in annual increments, ability to withstyand and recover from pruning etc. so whatever you choose as definitions I would suggest should be useful to inform the decisions that you arte about to make to serve the purpose of the survey.

 

Or you can just do what everyone else does, mostly involving box-ticking for BS5837 surveys.

 

Knowing is useful, but understanding is by far the greatest prize.

 

Hows about you let us know how you get on in the assessment?

Just reviewing my BS5837 Appendices master copy (I know, sad, it's New Years Day) and at 4.4.2.5 g) the standard gives both early and semi-mature as example categories - just to help confuse things even further.

 

And I think the 'reliable source/good authority' was from here http://www.tree-care.info/uktc/archive/2010/msg01701

more research revealed more information.

Hi Gary - big thanks for the info on the definitions, working through my Level 2 currently and hit a snag on putting age ranges to the BS5837 definitions.

[Gary Prentice]

You're welcome.

What was the outcome of the course then Twigger?  If you're still tuned in....?
