For
starters, they don’t mow the lawn – at least, not very often. And it’s not
really a lawn. The Downs – a patch of several acres on the north side – has
been allowed to grow without seeding or herbicides for several years. “For the
first two years after we stopped mowing, the grass grew way too long,” said
Lloyd, whose looks and manner seem rather more like those of an insurance
executive. “But we left it alone. After that, the wildflowers and other plants
grew in and now keep the grasses naturally short.” I’d been walking through
this field for a week on a paved path and it never occurred to me it was in any
way untended. Its texture is lush, dotted with flowers, and far more engaging
to the eye than mere grass. Departing from the traditional, prim,
English-garden aesthetic, the Downs is a gently rolling meadow upon which wild
birds forage and students often relax and play sports. Its upkeep is thousands
of pounds less per year than a traditional lawn, and when local farmers mow it
twice a year, they use the clippings to feed livestock.
Although
“not-doing” might be at odds with a traditional British work-ethic, it seems to
produce quite good results on the UON campus. Fallen dead trees, to cite
another example, are seldom removed as long as they’re not blocking a roadway
or heavily-trafficked path. Allowing them to rot where they lie creates a
habitat for plants and fungi which nurture insects, which in turn feed birds
and, most important, bats.
Bat numbers
have drastically declined all over
western Europe in recent times because of habitat loss and pollution.
Fortunately, scientists have been able to demonstrate that some bats are
keystone species, meaning that if you lose them, because of their
interdependence with so many other kinds of plants and animals, it would cause
significant damage to the ecosystem. (Honeybees are another keystone species,
as are African elephants.) The problem and its projected consequences inspired
a willingness to provide international protection for all European bats
(intentionally killing them can be imprisonable), and this order, combined with
a willingness to appropriately manage the campus, now makes it possible for
nine species of bats to flit freely through the night skies at UON, and roost
in the hollows of its ancient trees and buildings.
To me, the
most interesting part of all this is how UON’s biodiversity action plan
ingeniously leverages the bats’ ‘keystone-species’ status. By doing things to
the campus which are known to nurture and protect bats – and not doing things
which would threaten or compromise them – Lloyd and his department can be certain
of making life good for a wide range of other species who benefit directly or
indirectly from the bats’ presence, or who share their environmental needs.
This centering of an environmental policy around a single, influential group of
species provides a way to measure the overall quality of the environment
cost-effectively and relatively quickly. Threats are more likely to be detected
and dealt with before they do irreparable damage. But how to communicate these
benefits effectively to the public in order to build and maintain their
support?
The answer
to that question came during a conversation with another person whose work
involves surveying protected species, including bats: Mark Woods, a Senior
Ecologist at BSG Ecology, the company that prepared the Biodiversity Action
Plan for UON. According to their website, BSG provides ecological consultancy
for a variety of clients such as property developers and government agencies to
ensure that they comply with environmental law and local, national and international
biodiversity policies.
Woods noted
how UON’s policies and campus management help to market its environmental
credentials and promote the campus as a sustainable and attractive place to
study . The campus has become a showpiece of open space in the City of
Nottingham, which is one of Great Britain’s greenest cities, maintaining over
200 wildlife-friendly areas within its boundary. Woods and Lloyd both mentioned
that universities are a critical element in scientific outreach to the public,
who often respond by raising funds and providing volunteer labor to support new
initiatives. In the often-torturous relationship between science and the
public, is this one of the less-bumpy places? If so, what can be learned from
it?
During the
year, citizens are invited to assist with nighttime bat surveys, sometimes led
by Woods, who’s also a part-time lecturer at Nottingham Trent University, and
member of the Nottinghamshire Wildlife Trust. (Other activities on the UON
campus include counts of scarce plant species, wildlife walks and bird surveys
usually run by local experts.) The surveying teams use a handheld bat detector
to convert the flying mammals’ high-frequency echolocation calls to a sound
within range of human hearing. The frequency and type of call enables
identification of the species. It’s a relatively risk-free adventure in nature
which connects members of the public with science, but Woods says he rarely if
ever mentions science during bat surveys. Likewise, Lloyd never mentioned
science during the grounds tour, even though we were hip-deep in it the entire
time.
As in
grounds-keeping, is “not-doing” part of effective science communication? Woods:
“Don’t mention science. Let people get interested in what’s in front of them
because that’s what gets them hooked. The environmental studies, the
evolutionary evidence, the biology and chemistry, can all come later, once they
really want to know how nature works.”
