Yorkshire Wildlife Park’s polar bears have been the focus of attention
for cameras again – but this time they were helping wildlife research.
The thermal outlines of park favourites Victor, Pixel, Nissan and Nobby
were captured by a series of specialist lenses in a project that could
save polar bears when they come into contact with humans.
Their heat readings – revealed in Polar Bear week which runs from the
4th to the 10th of November, will form the basis of new technology that
could provide an early warning systems at dumps or the outskirts of
towns that attract hungry bears.
Anne Dangerfield, a geo-scientist with the Arribada Initiative which
specialises in accessible conservation technology, spent three days at
the award-winning park testing different sensors to identify key heat
signatures.
Polar bears are difficult to profile with conventional thermal imaging
as they are so well insulated that it is hard to differentiate them from
the ground.
The project, funded by the WWF as part of its Human-Wildlife Conflict
Tech Challenge, aims to create technology that can alert a community
when a polar is nearby and minimise the risk of it surprising people.
“An algorithm will be trained to recognise a polar bear from other
animals or objects and send an alert to the community, informing them a
polar bear is present at a certain location,” said Anne, project manager
for Arribada’s thermal and optical imaging projects.
“We hope this system will decrease the number of polar bears and people
killed in human-wildlife conflict. Being alerted to the presence of a
polar bear will reduce the number of times community members are
surprised and unprepared to meet a polar bear, which can result in the
bear or person being killed.”
Data taken at the park, at Branton, near Doncaster, will be evaluated
and used to train a computer algorithm that could generate a low-cost
alert system.
“We saw at YWP that at closer distances (less than 10 meters) it is
possible for a person to identify a polar bear by its thermal image,
especially if the bear is walking or moving around,” she added. “Because
our system is designed to be used in smaller community areas polar bears
visit, such as dump sites, the cameras could be set up to minimise the
distance between them and entering polar bears.”
Disappearing sea ice and vastly reduced hunting grounds are driving
polar bears to seek food in villages and towns placing them in potential
conflict with communities.
“Technology has the ability to change, improve and conserve our world,
but too often it is not available to people and communities who need it
most,” said Anne. “Our idea is to use thermal sensors to create an
affordable, automated early warning system to alert communities to the
presence of a dangerous animal.
“It was great to spend time at the Yorkshire Wildlife Park furthering
this research. My first impression was the amount of space the animals
have in their habitats. When I first saw the rhino enclosure, its size
made me think it was private land that couldn’t be incorporated into the
park! My second impression was of the quality of the keepers. They were
a great help getting the closer up footage of the bears, but more than
that, they were all very passionate about the animals’ welfare, making
sure they were healthy and happy.”
The park’s four bears live on the ten-acre Project Polar reserve and are
part of an international programme to preserve the species that is
suffering a dramatic decline in numbers.
YWP is celebrating its Polar Bear Week, running from November 4-10,
which devotes a period of time to polar bears and draws attention to the
challenges they face in the wild.
This years’ Polar Bear Week theme is citizen engagement and the park
will promote a series of daily actions to leverage people’s power as
citizens to help save the sea ice that polar bears desperately depend
on.
A new initiative at the park this winter is their Bear Necessities
Assembly, aimed at Doncaster schools, which introduces pupils to polar
bears and what they can do to minimise the threats they face in the
wild.
The Yorkshire Wildlife Park education team will run the sessions to
raise awareness for key stage one and two schoolchildren until February
2019.
At the end of each session, donations are collected for the Yorkshire
Wildlife Park Foundation.
