That'll be the extra nitrogen because it's a legume, smells like split peas when you fell it.

Yes but how much air does one need to carry that moisture away? Agreed but it's the balance between the power to move the gases, both air and vapour, against the cost of heat. A hot dry breezy summer's day beats all else The algorithm still depends on knowing the cost of electricity to blow. As blowing costs go up and heat stays cheap it pays to raise the temperature. All agreed, it's pointless having a dehumidifier in an open system, they only pay in a recirculating system. How many of you have a drying room with dehumidifier rather than a tumble dryer, I find it much cheaper to run. The same is true of a timber dryer, a small amount of cheap heat in equilibrium with the losses from the chamber and the dehumidifier recycles all the latent heat of the water evaporated back into the chamber. You still have the cost of moving all that air through the wood surface area and then over the evaporator of the dehumidifier and the lower Delta T between vapour and condenser the less work to pump the heat. Take this to the ultimate and that's the dryer we never built because the capital cost didn't appeal to our client when gasoil prices were low.

Spruce won't last in contact with the ground, it also resists preservatives unless by sap displacement when green. If you must use them cut a chainsaw slot in the bottm to take a 6mm steel plate embedded in a concrete stanchion/pedestal and through bolt.

I have spoken with a lady from FC Edinburgh and I see now the link below has been edited Forestry Commission - Q & A - Chalara legislation The order is in force and the ambiguity about branches twigs etc, being part of a tree has been removed. The actual order is at The Plant Health (Forestry) (Amendment) Order 2012 and mentions only plants of genus Fraxinus L. intended for planting. I think this means all arb arisings are exempt except from infected sites,

I didn't get a further reply from FC before close of play yesterday. It seems that the order did come into being yesterday but unlike you I see ambiguity in the wording of the link Forestry Commission - Q & A - Chalara legislation That is a summary of the proposal, not the actual regulation. On the one hand it suggests trees cannot be moved within UK at all but stem wood is an exception and no material can be moved from a site with an infection. I cannot see any map of sites which have been served with the required plant health notice. Map of current sites care of BBC http://news.bbcimg.co.uk/media/images/63787000/gif/_63787113_ash_tree_624.gif However further down in discussing what can be done with wood from an infected tree is says branches, leaves, ( racemes?) and twigs (buds?) are parts of a tree. On the precautionary principal I would not move lop and top or chipped lop and top off site, I have been overruled on this by management. What we don't know is if spread has been by wind or by fomites travelling at 70mph from Felixtow, Harwich etc. I would like to see a cite for the viability of the spores because whilst wind-borne spores may be susceptible to ultra violet those hidden in muddy boots may not see daylight, we saw how human borne fomites was the chief vector of FMD in 2001. I think FERA always knew the disease was inevitable given normal trade and movement of people and the cost of doing anything was not worthwhile to most Britons. I agree with Tony the spread becomes inevitable once the sexual stage reproduces spores and this will be next June, the question is how resistant are our ash and will it spread to isolated trees/woodlands.

Did the proposals in Forestry Commission - Q & A - Chalara legislation get enacted? If so then it looks like arising from ash felling other than stem wood will not be able to take off site I have spoken with FC plant health and they cannot answer this question at the moment.

Thanks for the link. It raises the question how long are the spores viable? There seems some scope for intervening with leaf litter at the sexual stage. Why does the anamorph have a different name from the telemorph?

I meant fungus not virus Is there an "edit own posts" feature I've missed?

Yes, the english elm (procera) was reckoned to be a hybrid that didn't set viable seed. Probably selected because of the straight stems it produced. Thus it's DNA didn't change and it spread by man and vegetative suckering. It was the combination of the yeast like fungus (Ceratocystis ulmi then but since renamed OPH??? novo ulmi), the vector ( scolytus beetle) and the high dependance of the tree on the current year's vessels to carry water to the crown that cause the tree to kill itself as it reacted to the fungus with tyloses filling the vessels. If you remove one of these, the ability of the beetle to lay eggs in the phloem because it is too narrow, as in a <25 year old tree, then the stem doesn't get re infected. Whether coppicing all susceptible elms would eventually kill off the fungus I don't know but I think it is a viable way of continuing an english elm population. This chalara fraxinea appears to be a wind born fungus so not much holding it in a naive ash population, some ash may have resistant dna and these would eventually re colonise. Elms were a big portion of the hedgerow trees in Surrey, a lot had died from a less virulent form of the disease in 1927 but large individual isolated trees were common in my teens plus the may 60 cms dbh 15 m tall regrowth from the earlier infection.

Agree with this 100%, the last thing they want is an on site confrontation, the follow up letter is the real deal.

They look like sensible figures to me Tom, I did much the same in the 70s and aimed to give the equivalent value as the retail price of delivered coal, which was a falling market then as the gas network expanded. I now consider this to have been a big financial mistake as logs are a luxury good, one should charge what the market will stand. I haven't got my head round whether each of posters' "cubes" is actually comparable but would expect to be charging at least 25% above the competitive calorific value. The FC in the early 80s published a guide and pushed for the idea of a solid cubic metre equivalent for log sales, I think I still have some of the leaflets they produced for handing out to customers.

Mine was non com in Burma, had panic attack on his dying day that the "japs were coming" Lost one uncle over North sea and both of them were from reserved occupations. Me too and they will always have my support and donation. I don't wear a poppy and don't believe we should be occupying a foreign sovereign nation.

Strikes a chord, I'm baby boomer generation and my sensible contempories took jobs with good pensions and now have been retired for a decade. Met one at a funeral, ex senior DWP management, who now volunteers doing woodland management for NT on a site I was the regular contractor for. I don't particularly resent it and my pension prospects are such that I need to die long before the age my father did, he retired at 53 with a state pension which still pays my mother's keep and is better than my pay. What concerns me is the loss of productivity affecting the overall economy.

My 1989 ex mod one does about 19 poodling on petrol and 13MPG on LPG, the economy doesn't change much with the lpg whether you do 70 (if you dare) or just potter. I didn't do a lot of towing but that did drag it down. Haven't used it other than drive to the MOT station and back for 4 years, since becoming sedentary. I think it would be considered underpowered ( about 120BHP with the choke restrictors taken out) compared with a modern diesel, though I did commute round the M25 45 miles a day for three months at Hatfield park, 45 miles and almost dead on an hour.

I doubt there was much trade in native species in 1970, it's grown with globalisation. GATT in 1994 brought a lot of imports in. This business of shutting the door after the horse had bolted is similar to how FMD got out in 2001, the government announce a transport ban for the following day at midnight and a haulier decided to load animals up and make the trip to Devon, dropping off some near Liverpool. The FC scientist on BBC tonight was suggesting the ban would start before the November start of planting but that has allowed a lot of pot grown stock to continue in. From 10 years back my brother in law was finding it was pot grown native standards from Italy that were out competing him.

You may be after one of the divisions of ISS, they took over waterers tree business many years back , I didn't know they were into ua mostly facilities management, Swedish owners I think. I remember them when they just did those continuous toilet towels in schools.

I'm embarrassingly poor at this myco recognition, without looking anything up: Meripilus giganteum Parasol Piptoporus betulinus Oyster Pass Pass ??

Has anyone used one of these? The idea seems sound, the offset converts some of the kinetic energy into a sideways force and the piece at the rear stops the axe following through.

Wanna buy some wood?

Good point but the same is not true of golf courses or university campuses where I see herbicides used excessively, nitwork rail seem fairly liberal too.

That is the UK rules page and for most people this will not apply, if you follow the flow chart on page 11 you will see all commercial vehicles over 3.5 tonnes MAM have to comply with EU rules unless they come under one of the exemptions or derogations. The exemptions for class of vehicles will not apply to most of us but if you scan on down to page 15 we have: "Vehicles or combinations of vehicles with a maximum permissible mass not exceeding 7.5 tonnes that are used: by universal service providers as defined in Article 2(13) of Directive 96/67/EC of the European Parliament and of the Council of 15 December 1997 on common rules for the development of the internal market of community postal services and the improvement of quality service to deliver items as part of the universal service; or for carrying materials, equipment or machinery for the driver’s use in the course of his work. These vehicles shall be used only within a 50 km radius of the base of the undertaking and on the condition that driving the vehicle does not constitute the driver’s main activity." The 4 hour limit mentioned in UK rules has gone. so one could drive 4 hours to work, take a break and cut a tree and drive 4 hours home and still not need to use the tacho if you are within 50km of base and the MAM is less than 7.5 tonnes. Not that my boss believes me

That was my understanding, so it's alright to compost stumps in situ? We've lost many herbicides for use in forestry because the market is relatively small and not worth the suppliers pursuing a licence. Others like the residual ones went because they were found in groundwater/aquifers. The bracken control group appear to have successfully fought a rearguard action to continue using asulam for the time being

From the soft texture of the fruit I was thinking viburnum but the obovate leaves aren't right for common ones

So the MAM was more than 7.5 tonnes because the weight of the trailer is added to the gross weight of the truck. The derogation for carrying tools for the driver's use is only for a MAM of less than 7.5 tonnes. I have taken this to mean that as soon as I couple our 750kg chipper to the 7.5 tonne I must use the tachograph.
