  1. It is now often attributed to a bacterium and called Chestnut Bleeding Canker. http://www.bspp.org.uk/NDR/july2007/2007-64.asp Phytophthora is said to be quite rare in causing these symptoms.
  2. That is interesting Tony- P. aurivella on Robinia. I have often seen it at 10m in cavaties on beech stems. The vagaries of tree/fungi interaction! I know what you mean about Ganoderma brackets- it makes you wonder how old they are sometimes. Here is the inside of an old Phellinus robustus bracket, where the age can simply be counted.
  3. Looks like you're having fun vduben- thats what it's all about
  4. Tony, is the group of yellow toadstools Pholiota aurivella? I have seen then exclusively on beech and was wondering about the decay as there is little literature. Not to that extent, but this is G.pfeifferii. It is interesting how this bracket has 'callused' over on the left of the photo.
  5. Hi Kev. It looks like the obvious honey fungus, but ash are supposed to have a level of resistance. Perhaps Collybia fusipes or a Pholiota. For me- too hard to tell from the photos i'm afraid.
  6. Yeah Treediver- Acacia pravissima, nice one
  7. Nice one Treediver, you got the first one- Acer palmatum 'Kihachijo'. The second is Australian though.
  8. It is true- its becoming harder to retain dangerous trees, which are the best for habitat. Depending on the management of the park, there are ways of retaining dangerous trees. For instance- don't mow under the tree leaving an area of long grass often prevents people going close. It is also a great way of alleviating compaction- the grass and microbes will soon aerate the soil. Fallen branches can be re-positioned to create suggestive barriers or thorny bushes can planted. Desire lines cans often be diverted using dead stems or branches.
  9. Did the St. Johns 4 day first aid course. A few months later a mate fell out of a tree and it definitely helped in the time it took for the ambulance to arrive having done the course. If anything, I think it helps to calm a bad situation.
  10. I would- planning to check out Canada soon
  11. Nice thread Monkeyd. IMHO, conservation and arboriculture are very closely related now. Past practices have reduced habitat and eco-systems to the point of many life forms becoming threatened with extinction. Bats, stag beetles, violet click beetles, certain fungi, etc, etc. Any work- such as coronets or erecting standing deadwood- has got to be beneficial to the environment and should be carried out where appropriate. There are obvious safety implications which should be addressed- as Tockmal says, this kind of stuff should be done from mewps were possible. Vduben's point is interesting because there is theory behind this. Often you get a lot of regrowth from a pruning point, resulting in a pollard. If you look at a trees recovery from storm damage, you notice the regrowth occurs over a longer length of the branch. Another idea is that cutting with a chainsaw can kill the cells in the branch causing die back, whereas ripping does not damage the cells, resulting in a better response in the tree. The photo shows the formation of a second canopy after storm damage. This might seem an odd idea- carving standing deadwood into sculptures in public and private gardens. It would be a good way of retaining the habitat a dead tree offers and would be pleasing on the eye, making customers more amenable to conservation. You never know, it may work!
