Dear Victoria<br>
<br>
This is an issue I considered when compiling a synopsis of evidence
on bee conservation in 2010, which is published online. <a
href="http://www.conservationevidence.com/collected-evidence.php?id=39">http://www.conservationevidence.com/collected-evidence.php?id=39</a><br>
<br>
The intervention 'Control deployment of hives/nests' basically means
not allowing managed bee hives in or near conservation areas. As you
can see from the link, I found no evidence on the effects of
exerting this control, but there is evidence in the background to
this section (if you download the pdf via the link on the right)
relating to the impact of nearby honey bees on bumblebee colonies.
Here's the text:<br>
<br>
Being near honey bee Apis mellifera hives has been shown to reduce
worker size (Goulson & Sparrow 2009), forager return rates, the
proportion of foragers collecting pollen and the number of
reproductives produced (Thomson 2004), for bumblebee species in the
UK and the USA. However, we know of no direct evidence of a positive
effect of excluding A. mellifera hives on populations of bumblebees.<br>
<br>
Goulson D. & Sparrow K.R. (2009) Evidence for competition
between honey bees and bumblebees; effects on bumblebee worker size.
Journal of Insect Conservation, 13, 151‐163.<br>
<br>
Thomson D. (2004) Competitive interactions between the invasive
European honey bee and native bumble bees. Ecology, 85, 458‐470.<br>
<br>
Hope this is helpful. I'd love to see a controlled trial examining
the responses of wild bee populations over several years to
exclusion of honey bee hives.<br>
<br>
All the best<br>

type="cite">I am interested in the members of this list's
responses to the question, "should honeybee colonies be allowed in
conservation/protected areas"? I.e. While honeybees can certainly
fly from their colonies on private land into a conservation area,
should beekeepers be allowed to place their colonies directly into
the conservation area?<br>
<br>
A few of my initial thoughts:<br>
against<br>
- honeybees are non-native; generally we try to avoid introducing
non-native species into conservation areas<br>
- honeybees may out-compete native bees/pollinators, thus they may
negatively affecting the native/local pollinators and the
native/local plants seed-set<br>
- introduced species (incl. honeybees) may potentially spread
diseases<br>
<br>
for<br>
- honeybees may already be present in the conservation area if
there are beekeepers with hives nearby<br>
- beekeepers would be able to have a pesticide-free and
undisturbed location for their bees<br>
- if near a public trail/info centre, could use them as an
opportunity for educating the public about all pollinators<br>
<br>
<br>
Any other thoughts/discussion?<br>
