Get hold of Kveldsanger, he's reading a book about trees in the Israeli and Palestinian conflict. Seriously!!

Lightning damage to a Cedar!

Localised distribution of Fomes fomentarius

Clones of cultivars as I understand it -
Localised distribution of Fomes fomentarius
Betula replied to David Humphries's topic in Fungi Pictures
take a read of this Plane trees - index page Not seen Fomes on any Planes so far but quite a bit of Rigidporus -
I forgot to mention that, fantastic book!
-
Collins Tree Guide Modern Arboriculture - Alex Shigo The Principles of Tree Hazard Assessment and Management - David Lonsdale Diagnosis of Ill Health in Trees - Strouts and Winter Those I would say are the corner stones, I'm sure other people will mention others. Beyond that the Forestry Commission, Arboricultural Association, RFS, RHS, LTOA and other websites have a lot of fantastic pdf's on a lot of subjects which are well worth a read. Books are great but can be expensive, the internet is a fantastic resource these days!!

Having grown up in Bedford I was quite excited to see this thread title only to find it's something else entirely!!
-
I can't remember the exact year but those Catalpas were one of the first to be planted in the country when that area was designed. You could probably find the exact year
-
I would say leave ideally, see how it recovers unless there's significant hazard
-
I found out what the moth was but forgot to say, sorry!

Multiplex is the one that is the big problem for us

I'm also doing that and will probably be tricky trying to spot it through the anthracnose! (if it is there). I did hear a theory that X. fastidiosa is not well suited to the UK climate so may not be as effective, probably just a hopeful theory though! I also found something similar in a nursery over the weekend, will go back to get a sample

I think it is Phytopthora, I think P. cactorum maybe P. plurivora? Both go for the roots and lower stem. It's hard to give a prognosis over the web! But if there has been poor pruning in the past, likely that other decay has entered from the wounds and the root decay can also open to other pathogens. On the other hand they can recover and if there is good foliage then it may well do, Phytopthora moves through the soil in ground water not a great deal can be done to stop the spread unfortunately.

I disagree that it is bad for the willow to be honest. Mature Willows will drop branches anyway and the brown rot of Laetiporus does degrade the strength of the wood. It all depends on what's in or around the drop zone and if there are any targets. Laetiporus is a very important part of the ecosystem, as is its interaction with Willows

There is a product called Signum which has the active ingredients Pyraclostrobin and Boscalid. I only know of its existence though; not its cost, availability, effectiveness and ecological impact.

I swear they change the names and come up with synonyms to keep themselves in a job!!
-
Thanks, I checked out mycobank last night to find out and saw the same, anyone can change Wikipedia so not too trusting of that!
-
I've recently seen Polyporus squamosus being referred to as Cerioporus squamosus. Has there been a name change or does it have another name that I didn't know about? Or has someone got it wrong and I've fallen for it?!

Helps to finish off declining birches, like dignitas for trees!

Distance learning Arb courses & qualifications???
Betula replied to Hound-Dogg's topic in Training & education
I would really recommend getting some voluntary experience in a place like a country park or a nature reserve if you can. Give you a different perspective on trees in that environment as opposed to just tree surgery. A good way also to put the theory into practice as well as doing tree work -
I would say it is, always important to stay up to date with industry changes and quite a bit has changed in the last 10 years. Only £12.50 anyway. In the previous version they got the numbers of BS5837 the wrong way round so hopefully that's corrected!!

He's released a book titled A Guide to Tree Climbing. Encouraging adults to reconnect with their inner child by climbing trees https://www.harpercollins.co.uk/9780008153915/the-tree-climbers-guide
-
All it takes is one person who puts their weight onto a Massaria branch or touches an OPM nest then there could be huge consequences. Im always in favour of people learning more about trees and being more involved but not in this way. But then we are probably the tree huggers or h&s nuts referred to in some of the articles!

My first thought was deodar also

Transformation Nature seminar. Kew, 17th May.
Betula replied to Kveldssanger's topic in Training & education
With the live streaming/recording of seminars. Universities such as UCLA Berkeley and MIT often post a lot of their lectures on You tube, granted they are different things and have different copyright issues etc but it's a really good resource.
