where a large roosts split into two).
7 CONCLUSIONS
The paper has described the context in which the Welsh Assembly Government undertakes
its work with Lesser Horseshoe Bats and large new road projects.
It is true to say that our knowledge since the beginning of the century has improved, and we
are now able to refer to examples of successful mitigation to support the application of mitigation
in new circumstances after considering the context involved. However, some measures
which have been applied have had to be based on best professional judgement of the
situation involved, and only monitoring will tell whether they are effective.
We are hoping to:
• Continue to learn from our experiences, and the experience of others in similar
situations.
• Continue to improve the ability of engineers, ecologist and bat specialists to
understand the issues involved, and develop practical solutions to avoid, reduce
or if possible remedy effects.
• Improve the way we understand context of the projects and the use of the surrounding
areas by bats
• Improve the way we undertake Environmental Impact Assessment and “Appropriate
Assessment”/Assessment of the Implications on European Sites.
