Bat Inspection

[benedmonds]

Are you likely to be able to find a roost with a bat detector, presuambly you would have to be at the tree as the bat leaves or enters, the detectors can't pick up roosting bats...? or do bats echolocate while roosting...?

 

If a climbing inspection is required, which it sounds like. What's a good, afordable endoscope and if you find bats, does the roost become protected. Or can you get a licence from English nature? How does that work?

English Nature will give you the heads up ...

Hi chris, does that mean any work at all on a tree then? i.e deadwooding, thinning, etc. What are the signs of bats living in a tree too, just out of intrest really, never really had much thoughts on bats.

 

Hope you dont mind me asking Ben, not taking over your thread.

Appologies Ben, slight digression.

 

Saw this dead Bat on a gate post a couple of years ago up in Yorkshire.

Stayed attached for a few days, then dropped to the floor and was relocated by some wee beastie or other.

 

Always thought that it was a large male Noctule about 80/90mm, but never positively Id.

Any thoughts Chris ?

 

Btw, don't go photographing live bats. Disturbance and the like.

I looked at a job on friday that involves the removal of a tree near a building that is home to many bats .

The warden told me that bats living in trees rarely stay for more than a few days before they move to a different tree ( travellers of the bat world it seems) A tree that has no bats on inspection may have residents a week later when you fell it and also the reverse applies and they may have moved on when you think they are there. Its a tricky one.

QUOTE:I noticed a comment about felling the tree or limb etc and leaving over night to let the bats escape... do not do this as again you will have disturbed any bats and broken the law.QUOTE

 

I've have felled a few trees that they thought there were bats in, but with a crane so there lowered slowly and left for a few weeks. Does this mean its wrong? I did have a bat inspector there the whole time watching my every cut and move tho. This is what he/she advised. Was i missinformed then or does everyone have there own way of doing things.

 

Had them there for newts too, had to lay hundreds of mtrs of newt fencing.

Chris, would you have any specs and info on making bat boxes.

The licensed bat handler who you were working with will have had a license from DEFRA to carry out the work, in which case you were fine.

 

I have done several similar jobs, never found a bat in a tree though.

Did once very carefully lower a hollow limb only to discover it only contained a Gray Squirrel.
