So, ive got me a job! We quoted a removal of 14 huge poplars (Populus canaden.'Marilandica', 434cm around at breastheight, planted around 1890-1900, 100feet). Those are listed by the dutch treecare foundation as beeing rare and old growth. (over 80years we call old growth:) The city made a preservation in the permit that those trees should be inspected on bat habitat first before felling starts. Also we need to put up 4 bat shelters in nearby trees as well. Al this has to be paid by the tree owner. 28meter skylift, operator, bat professor (not batman) the whole circus.... Additional we got to prune/deadwood the remaining poplars and do a complete VTA checkup. almost 4 weeks work for a 3 man crew. No space for a crane so we take them down in pieces working from a skylift.

I have to check the trees on 6 february. Thats monday. I bring my ms200t up the tree and maybe i have to cut them out. I dont mind the wood, we cant sell it because its full of scrapnel from WW II. I hope its good weather so i can make some interesting pictures.
 
I believe the approved method for bat extraction in the UK is to let them all leave the roost at dusk and then plug the hole so they cant get back in!

Seems a bit unkind, but its probably better than waking them up midday with a 200T!
 
The problem is i think in this time of year they dont fly out :)

I am to operate the skylift with a very educated bat professor joining me. So maybe a bit 'over the edge' saying ill cut them out but they have to be relocated before felling starts... Thats agreed in the permit thats issued by the state government.

I have once cut trough a woodpeckers abandond nesthole that was occupied by bats. They flew out and settled in a nest cabin a few trees further. Those bats (i assume that the onces flying still around) are still present at that farm.

IF we find any bats ill take pics of how and where we relocate them. Maybe i have to do overtime to take um out in night :))))) I wonder what and how the expert wants it to be done....

Years ago I worked on the Notorious Newbury Bypass Project. Six weeks of being chased by hippies and a Channel 4 news crew!

Anyways, our job was to remove possible bat roosts before the clear felling began. We had a Bat specialist with us, he had located 120 trees with possible bat roosts. We had to dismantle the trees and then lower out the section with the roosts. He would then get us to cut through the section at the exit/entrance to the cavity so he could look inside.

In the six weeks we found 5 Bats! They were then released in a different area. This was all done in winter, so the theory was that once all the roosts were removed, no other bats would move in before or during the felling work, which took another two years to do cos of all the protesters who moved in up the trees. They weren't treated with same respect as the bats!
 
Yes the "Notorious Newbury Bypass Project" where are you now Swampy, Once knew an arborist who taught these hippies how to climb these trees, so that they would nt kill themselves while trying.

The greatest tree hugger war ever. Well in the UK at least.

Look forward to seeing the extraction photos of the bats Ronald, delicate area protected speices. One of the climbers I know here just recently had to relocate over 600 Crows nests, as they they were making to much noise by some big hospital. Is that not an omen to remove crows nests?

Hi,

Today we did the search for bats. We didnt find any in the 14 poplars we have to remove. Some nice hollow places but most were wet, filled with water or to shallow.

This summer the bat professor already did a (sound and vid)search at night to find out what species does live here. I believe he told that about 5 different bats were present around those trees. 2 of those species are known to go dormant in hollow trees in winter.

He did find some evidence that some hollow parts and some huge opened barkridges are used in summer/autum by bats to spend the day or lure the females.

We found at one side lots of those small crow nests inside decayed topped trees. In one tree we found a abandond owl's nest. Maybe it will get back in spring.

They are cool.... I like the lift with knuckle-boom, telescope better. This one is 28 meters and still 6-8 meters short. Even when i drive the thing straight under the crown. (hate that as branches will target the lift) When flopping a top (at 28 meters more then 60 year growth, about 8 meters lenght) i wrecked a cattle-fence, that will cost me 20 meters 20x3 cm board to build a new :)
 
Like the Pitures Ronald brings back memories of working in Holland, (OP DE DIJK) we used these lifts there alot also, Especially during the time after that big storm that ripped through in October 2002. Man we were so busy, back then. We also had to use one alot when one of our colleuges recked our 26m highworker up there in Stompetoren. It was only 80,000 € to repair.
