Dr. Luise Hermanutz with the rare braya | |
In a lot of places, we don’t even know what we
have!” Dr. Luise Hermanutz, an assistant professor in Biology, and co-chair
(with Professor Henry Mann of Sir Wilfred Grenfell College in Corner Brook) of
the provincial Braya Recovery Team, is very excited about her latest project.
The Long’s Braya
(Braya longii) and the Fernald’s Braya (Braya fernaldii), are arctic-alpine like
plants that have been found in the limestone barrens on the Great Northern
Peninsula; an extremely unusual habitat that is home to several rare species of
plants. Of course, Newfoundlanders often find it hard to believe that our
province could host something so unique. But if you’ve ever driven up the
Northern Peninsula and seen this landscape - “it looks like open Arctic terrain”
between a roaring, cold Atlantic ocean and a much-used paved road - then you
would probably doubt no more.
“This is the only
place that these plants can be found in the world,” said Dr. Hermanutz, a plant
ecologist, who with the help of a recovery team, is working to ensure that these
plants will persist in their natural habitat.
The plants grow only
in these barrens, and because these barrens are so rare and so much has been
lost to quarrying, the plants are few and far between. In fact, during its three
years on the Northern Peninsula the team has only found four populations of
Long’s Braya, which makes the plant an endangered species. The Fernald’s Braya
is not quite as scarce, however; it has been listed as “threatened” by the
Committee on the Status of Endangered Wildlife in Canada, the body that
classifies wildlife. It classified the Long’s Braya and the Fernald’s Braya in
1997.
The Braya Recovery
Team was designated by the provincial Forest Resources and Agrifoods minister to
study the plants and the habitat, and to make recommendations to ensure that the
species do not become extinct. Members of the team include the chairs, Dr.
Hermanutz, and Henry Mann; Dr. Trevor Bell, a geographer; Dr. Wilfred Nicholls,
director of the Botanical Gardens; and others including wildlife specialists,
stewardship specialists, and staff from Parks and Natural Areas. The team began
its work on the Long’s Braya and the Fernald’s Braya in 1998. Since then, they
meet every summer during the first week of July on the Northern Peninsula to do
further research.
The team’s mandate
is to produce a recovery plan. This task includes making recommendations based
on the team’s work to ensure that the Braya does persist, and hopefully to
“downlist” the plant so that it is no longer considered endangered. The draft
recovery plan has recently been submitted and Dr. Hermanutz is very pleased with
that.
The work is not all
about the plant, however: it’s also about
“We’re not just
fulfilling our own mandate, we’re trying to get the best of both worlds,” said
Dr. Hermanutz. “There are benefits for the people in the area, and we have been
getting locals in the area involved and interested.”
Dr. Hermanutz feels
that the preservation of the plant could be a part of a tourism drive to the
area.
“You would not
believe the people we see. When we’re in the field we see people from all over
the world; we see Germans, people from Japan. People come out of their way to
see these plants. They get to see plants that they would otherwise have to go to
the Arctic to see.”
The recovery team,
with the help of the Green Team are spreading the word about the plant and its
rarity to locals in the area. This way, people can work together to secure a
long‑term land use planning strategy to ensure that people get what they need,
but still ensure that the plant can persist. They have also created an ex situ
conservation strategy for both species of braya at the Memorial University
Botanical Garden. They will serve as a failsafe in the event that something
should wipe out the populations that are now growing in the wild.
“If we want to
restore the braya to its natural distribution – we know it was further north in
the 1920s – we have to know how variable the populations are.” The students’
work on the breeding system can determine this.
Dr. Hermanutz and
the recovery team are excited about their work to date and are happy with the
outcomes. Their recovery plan, combined with provincial endangered species
legislation that is currently before cabinet, will help ensure that even the
littlest things that make Newfoundland unique are protected. The project is support by the Endangered
Species Recovery Fund with money from the World Wildlife Fund, the Canadian
Wildlife Conservation Service and MUN Botanical Gardens.
