I think that a virus can be passed down to the next generation but not a bacterial infection. As bleeding canker is bacterial I would stick my neck out and say no. From an evolutionary point of view there must be resistant horse chestnut trees out there but lets no forget that bacteria can mutate and adapt much faster than trees.

If by reasonable you mean cheaper then you are competing on price not capability, reputation, level of service etc - all those things that professionals strive towards. Continually driving down prices does no good in my opinion? Cheers.

This may be of interest to some International Society for Fungal conservation society launches | Pests & Diseases | Horticulture Week (how do they know that only 5% of fungi species have so far been discovered?) Cheers.

You could try Rogers Trees and Shrubs | Trees and Shrubs Pictures and Reference covering both hardy and tender trees and shrubs. I can't comment on how good it is as I don't have an iphone.

Sorry guys, I think I have asked the wrong question. I meant to ask whether you think bats are using this hole. Does this hole look like a place that bats may be living? Many thanks.
-
Hi David. The hole is inside the hollow stem on the right at about 1m above ground level. The beefsteak was in a hollow at the centre of the tree about 0.5m below grass level. Thanks.
-
I came across this oak tree today with fire damage and other nasty stuff going on. Does anyone have any suggestions on what has caused the hole in picutre 7, I thought it may be bats? Cheers.

Hi all, Has anyone had any experience of the European Arboricultural Council: EAC - I see that they offer 2 qualifications 1) European Tree Worker, and 2) European Tree Technician. Does anyone have one of these qualifications - are they of use in the UK? Cheers:001_smile:

Trying to get my head around this. Are you suggesting that by creating a borehole there is a greater potential for fungal decay spores etc to colonise a tree via the vertical barrier than an open pruning wound? Don't all pruning wounds whether borehole or pruning saw create a potential entry, and the vertical barrier is present where any cambium/phloem/xylem is cut:confused1: -
Why do we worry about drilling small holes in trees with increment borers when we regularly expose the same type of wood when we make even the smallest of pruning cuts. How many highway and specimen trees are pruned each day with 50mm plus diameter branch removal, yet making a hole of less than 10mm feels worrying

The Forestry Commission has produced research on root depth http://www.forestry.gov.uk/pdf/FCIN078.pdf/$FILE/FCIN078.pdf. Its not directly related to subsidence I know but if conditions are suitable for roots beneath foundations at the edge of a building they could easily be there. This on its own would not result in subsidence though.

Anyone interested in wild flowers could try Wild About Plants Parish Pioneer and record flowers from their local area on the form at the bottom of the web page http://www.wildaboutplants.org.uk/wp-content/themes/plantlife/content/PP%20parish%20record.pdf. Looks like something the kids might enjoy too.

I agree but sometimes they do - they did in this case anyway. The makers seemed to take the most extreme case though. Was interesting to see the large root that directly pushed up and dislodged the pipe close to the house.

I think you're right graham - once an appeal is lodged (within four weeks of refusal) the Sec of State has six months to consider.
-
A TPO'd tree must be considered within 8 weeks and a conservation area notice 6 weeks. An appeal for a TPO refusal must be considered within 4 weeks. Not heard of six months though it must be considered long enough for the council to make a decision i guess.
-
I hope not. As far as I'm aware the long term prognosis is still unknown. Although I agree that a tree can't be functioning at 100% if the leaves are dying prematurely each year. Personally I wouldn't cull a hc tree just because it had leaf miner - i'd remove as many dead leaves as I could in autumn to break the cycle.
-
I don't know, but I understand that they've had it at Myerscough near Preston for the first time this year.
-
I've seen a lot of sycamore trees with brown curled up leaves this year from north Wales to Yorkshire. I know it sounds daft for the northwest of England but I think its down to drought in the early part of summer. I guess that next year they will be back to normal.
-
Thanks David I heard about the monitoring project on the radio a few months back - its worth a listen if you've got time. BBC - BBC Radio 4 Programmes - Material World, 10/06/2010 It ties in with a previous thread on leaf miner predetors.
-
I took this photo recently on a horse chestnut tree in Bury, Lancs. I understand from an article in the Arb Magazine that they may now be causing long term damage to hc. I recorded the extent of leaf damage at What's happening to our conker trees? - a nationwide study on leaf miner movement (sorry if this link has been mentioned on here before but i'm new to the site.) If not done so already others could add locations where they have seen leaf miner - particularly in north England / Scotland.

Roger Phillips has a couple of good tree and fungi ident resources. Check out Rogers Mushrooms at: Rogers Mushrooms | Mushroom Pictures & Mushroom Reference There's a link to rogers tree & shrub ident there too. You can also buy the books and they're fairly cheap.

I saw a Ted Green lecture a couple of years ago and he said the same thing. Said he has witnessed meripilus come and go on beech over the decades.
