Vicky Skirving stopped Fife Council in its tracks last week from cutting down trees to make way for a £500,000 expansion of the Steelworks Brae recycling centre.
However, a hasty survey carried out by consultants, has advised that all 22 trees ca
n go on the proviso that two of the oldest are taken down very carefully.
Chris Ewing, the council's environmental sustainability manager, said "I'm pleased that the survey advises that it is most unlikely that any of the trees are being used by bats for roosting.
"However, we do what needs to be done to ensure that the development works on site are carried out in a way that ensures that if there are any bats present they will come to no harm".
Fife Council contacted Vicky Skirving and sent her a copy of the report but she's still not entirely happy with the situation.
She said: "I'm pretty upset and angry about this. They are still cutting down trees that have been there for years and potentially ruining the habitat of a protected species.
"I saw one bat on Monday night and none since."
She added: "The report clearly states that the old trees show potential roosting features. What's the point in bat conservation measures when the trees can still be taken down anyway?
"Surely it would have also made common sense to put up bat boxes before taking the trees down?"
Miss Skirving said her campaign had attracted a good response from local residents and she thanked them for their support.
"I'm going to be present when the contractors take the old trees down whether they like it or not," she vowed.
"I'm not going to take their word for it that they will follow a delicate procedure properly after everything that has happened.
She concluded:"The workers have been alright with me though despite the fact that one of them had said I'd cost them a lot of money...oops!"
