How very dare you. :001_tongue:That is an simplified interpretation of someone elses work that I have clearly referenced and added my own thoughts to at the end:closedeyes:

Nice post Gibbon. Modifying the soil environment would improve site conditions for other species, but if you think about succsesion on a lake with a very wet edge the willows might be colonising more and more of the marshy land as they dry it out and other species colonising the land that has been dried out by the willows. Tbq number 2 Endomychorrhizal associations are formed by fungi belonging to the order Glomerales, ectomychorrizal fungi belong are either Ascomycytes or Basidiomycetes. The Glomerales are an ancient group of fungi and form associations with almost every plant and are not host specific. Some do form macroscopic fruiting bodies but this is very rare. The fungi are incapable of living without a host (obligatly symbiotic). They do produce spores and these can be found in almost all soils. There is a suggestion that they lack some of the genetic material for growth and reproduction and that this is suplied by the host plant. Fungi, Brian Spooner and Peter Robertsm (excellent book) - refers to them as Vesicular-Arbuscular Mycorrhiza (VAM) I dont think they produce fruiting bodies because they have no need for airborne spores because they are everywhere already. It is thought that Endomychorrhal fungi played an important role in the colonisation of land by plants, they are that old!! (400 million years).

Its all about the individual, man or women your either going to get on with them or you wont and they will either be good at their job or not.

Cheers for that Tony. I was not aware of the 2009 amendments. Here is a link to the interim guidance the Forestry Commission has published. I presume when these are finalised they would be the guidelines that would be referred to in court when prosecuting someone for an offence. They seem to move away from the idea that you need an expert bat survey when only potential bat roost sites are present, unless you are removing a quantity of trees with potential roost sites. They do say that if you are altering the canopy around a known bat roost it may be necessary to apply for a licence. Generally seems to be a very good document but primarily concerned with woodland operations. Hopefully all this is to current to come into the tech cert exam on Wednesday. http://arbtalk.co.uk/forum/business-management/7852-terms-conditions-protected-species.html

You just want to see pictures of toned men :001_tongue:

Im all in for the advancement of SRT stuff and am very envious of your unicender but you will wreck your rope with a Tiblock,. They are really for emergency rope ascents

There is an article written by Andrew Cowan called "Dont fall foul of the wildlife law" that includes some paragraphs that his company attach to their quotes explain to the client the responsibilities Arborists have towards wildlife. It doesn't include anything about who will foot the bill for any extra work but it is well worded. As it was written in 2002 it doesn't take into account the changes to the Habitats regulations 2007.

Interesting. Different niches exploited and different evolutionary paths followed i suppose. Willow and Poplars also have Stomata on the upper surface of their leaves. The stomata on the upper surface of leaves generally have much smaller appatures than stomata on the underside of leaves and species like Ouercus robur have many more stomata of larger appeture on their leaves than common lime. It may have some advantage in allowing more efficient cooling allowing leaves to stay more photosynthetically active in the scorching mid day sun, provided there is enough water available. I would think that stomata on the underside of the leaf loose water at a slower rate to those on the upper surface it may be an advantage for trees such as willow to draw up large amounts of water quickly to modify there soil environment. Maybe this helps Willows, Limes, Poplars to loose less functional xylem tissue when heavily reduced compared with species such as Oak where greater amounts of foliage are required to maintain functional xylem.

We have a 3.0L HPI Iveco at work, and previously had a 2.8 they are very nice.

It is my understanding that Airspades can potentially pulverise the soil destroying the peds. Fine roots can also be desicated in the process and michorhizal associastions effected. Bulk density analysis should show you the layers of the soil that are compacted. Mulching may work to relieve top soil compaction but the soil will remain susceptible to further compaction so you have to limit access to the rooting zone and it will do little to relive compaction of the sub soil. I think Lee's suggestion of radial trenching is an excellent solution to compaction. It deals with top soil and sub soil compaction, can be carried out without the need for expensive tools (although they may make the job easier and more profitable) and provides the tree with more available rooting area and fresh soil loaded with nutrients. When radial trenching is done well studies have shown the trenches to become full of feeding roots from the tree.

Mainline and a lanyard. Very very rarely use two ropes its generally not necessary and a bit cumbersome. The working at heights regulations 2005 do require 2 anchor points at all times, no exemption is made for arborists. Our only defence is that our industry guidelines (AA guide to good climbing practice and Afag 401) do not suggest a need for two lines at all times and describe methods of climbing with one attachment point.

Very true, im not a big fan off carbon offseting I think its generally a load of rubbish I was just trying to add weight to my point.

Im with Giles and Monkeyd, keep the fallen tree. Its interesting, a temporary carbon sink, a continual source of dysfunctional wood for years to come and potential habitat for Fungi, Bats, Staghorn beetles and many other creatures. Leaving the tree makes a bold statement about what is important to the people who are managing the land.

Go on tell us.

Very cool. I know the tree at Bryanston, so wheres this secret one then? And how tall is it?

What channel is that on looks excellent.

It is the duty of the local planning authority when granting planing permission for any development to ensure adequate provisions are made for the retention of trees. Town and Country Planing act 1990 and 2008.

Cool I reckon that makes a pretty decent answer.

Too tricky for me

I have the week off to revise for the exam. I am currently going through all the law stuff at the moment. Not long to go now!
