Summary:
Solutions to help pollinators can be tested using a 'virtual safe
space' tool created by scientists at the University of Exeter in
collaboration with farmers and land managers.



FULL STORY ========================================================================== Solutions to help pollinators can be tested using a "virtual safe space"
tool created by scientists at the University of Exeter in collaboration
with farmers and land managers.


========================================================================== BEE-STEWARD is a decision-support tool which provides a computer
simulation of bumblebee colony survival in a given landscape.

The tool lets researchers, farmers, policymakers and other interested
parties test different land management techniques to find out which ones
and where could be most beneficial for bees.

BEE-STEWARD -- which is freely available online -- is a powerful tool
that can make bumblebee survival predictions, according to a new study.

"We know that pollinator decline is a really big problem for crops and
also for wildflowers," said Dr Grace Twiston-Davies, of the Environment
and Sustainability Institute at the University of Exeter's Penryn Campus
in Cornwall.

"BEE-STEWARD takes into account the many complicated factors that interact
to affect bumblebees." "This provides a virtual safe space to test out different bee-friendly management options."


========================================================================== "It's a free, user-friendly tool and we have worked with land managers and wildlife groups on the ground to create it together." Disentangling the
many factors that affect bumblebee colonies is incredibly complicated,
meaning real-word testing of different methods by land managers is often
not feasible.

This problem prompted the Exeter scientists to create the BEEHAVE
(honeybees) and Bumble-BEEHAVE (Bumblebees) computer models. But to help bumblebees thrive across our landscapes, these tools need to be used by
people on the ground and not just scientists.

BEE-STEWARD has been designed with and for land managers, farmers and conservation practitioners to test out different ideas for land management
and predict the impact that these may have on bumblebee survival.

BEE-STEWARD is being used by the Bumblebee Conservation Trust to help
test and guide land management to help bumblebees and farm business
thrive in Cornwall.

Using BEE-STEWARD, bee-friendly actions are being tested across 1,500 ha
of land in collaboration with the Duchy of Cornwall Estate, the National
Trust, Treiwthen Dairy and Kellys of Cornwall.



========================================================================== BEE-STEWARD can simulate the growth, behaviour and survival of UK
bumblebee species living in a landscape providing various nectar and
pollen sources to forage on.

"The BEE-STEWARD model is a significant step towards enabling
practitioners to support bumblebee populations," said Professor Juliet
Osborne, who leads the team.

"The tool can be used to inform conservation and farming decisions and
for assigning bespoke management recommendations." Professor Osborne and
team won the BBSRC Social Innovator of the Year 2017 award for creating
the BEEHAVE models.

"We have worked with researchers and landowners who have been using the
model and have given us valuable feedback so we could improve our models further" said model developer Dr Matthias Becher.

"Testing the BEE-STEWARD tool has helped us predict how best to provide
new and improved habitat for pollinators in an informed way, considering existing and proposed flora, flowering times and location. This has
focused decision making by identifying pollinator habitats that are
lacking in a particular landscape, enabling us to focus our attention to improve and protect these specific areas" Ashley Taylor, Assistant Land Steward, Duchy of Cornwall Estate BEE-STEWARD could be an important
virtual test-bed for scientists exploring the impacts of different
stressors on bumblebees and used by those with little or no modelling experience. Enabling a shared methodology between research, policy and
practice for bumblebee survival.

"'The Bee-Steward model will be fantastic for conservation planning -- it
lets us time-travel to see the long-term results of changing management
and compare all the possible options to see which one will work out
best for bumblebees" Dr Richard Comont, Science Manager, Bumblebee
Conservation Trust.

The BEE-STEWARD tool sits alongside a wider body of research by
Prof. Osborne, Dr Twiston-Davies and Dr Becher around pollinator-friendly land-management.

Their work on the NERC-funded SWEEP programme has included providing
advice on Managing Green Space to improve biodiversity and wildlife
habitats and working on the 'Farming for the Nation' trial for a new Agri-environment scheme with Cornwall Area of Outstanding Natural Beauty.
