The science, policy and practice of the impact of predators on wild birds - nine
As a nature conservation organisation our aims are framed in terms of maintaining and enhancing populations of birds and other wildlife.
Published: 21st Nov 2022.
We believe in the intrinsic value of nature and therefore support the restoration of fauna – including top predators ‐ to its native range (where practical). We see the killing or taking of vertebrates as a matter of last resort that should be carefully justified on a case‐by‐case basis, rather than a uniformly acceptable everyday management tool. When we enact this policy, we do so with a clear focus on the biodiversity or other benefits that will accrue from our actions. The decision to introduce any form of vertebrate control (lethal or non-lethal) is therefore something we never take lightly. It’s always guided by the RSPB’s Council-agreed policy which predicates that any killing or taking of vertebrates we carry out will be: a) ethically acceptable, b) scientifically justifiable, c) legal and d) efficacious and practical.
Before the RSPB carries out any kind of vertebrate control, we first seek evidence that a problem exists. If there is good evidence that it does, we look for a non-lethal solution and, if there is one, implement that. However, non-lethal methods, whilst always the preferred way of doing things, are not always practical or effective and the problem may require lethal vertebrate control. In order to even consider this, the following four criteria must be met:
- That the seriousness of the problem has been established;
- That non-lethal measures have been assessed and found not to be practicable;
- That killing is an effective way of addressing the problem;
- That killing will not have an adverse impact on the conservation status of the target or other non-target species.
Only when these four criteria are satisfied is lethal vertebrate control undertaken. This is the case for all the figures presented below, which are for the most recent reporting period (Nov 2020-Oct 2021) in the interests of full transparency.
