The Newfoundland marten is a genetically and
geographically distinct animal. Its numbers decreased during the 20th century
due to habitat loss, trapping, and snaring. In 2000, it was classified as
endangered. In 2007, the population had increased sufficiently and the
Newfoundland marten was re-classified as threatened. Today, there are signs
that indicate that there is an increase and that marten are returning to parts
of their historic range on the Island of Newfoundland.
The Newfoundland marten is gaining ground through stewardship!
Hair
Snagging in Newfoundland
Over
the years, many people from a variety of organizations have been contributing
to the recovery of this animal. Since 2012, Intervale has been coordinating the
work of 90 volunteers, who help establish the locations of marten across its
forested habitat in Newfoundland.
The
methodology was developed by researchers in the Newfoundland and Labrador
Department of Environment and Conservation, Wildlife Division. Marten are
seldom seen, which is why an attraction method is needed. The technique is
non-invasive and does not harm the animal. Volunteers collect hair samples by
means of a wooden apparatus called a hair snag; it is shaped like a three-sided
box and open at both ends. The device is fastened to a tree at chest height,
baited with sardines, and made attractive to marten with the scent of skunk. If
a marten visits the box, a tiny sample of its fur is left on sticky tabs that line the inside of the box. Volunteers
monitor the boxes every 10-14 days, collect the hair samples, and send them to
the Wildlife Division. Researchers test the samples for DNA, a process that
enables them to confirm the presence of marten and to track individual animals.
In
2016, a total of 84 hair samples were collected, of which 41 are suspected to
be marten. With new samples coming in week by week, the number is always
changing. These samples will be sent for identification. From these data,
researchers are able to identify from each sample representing marten, the sex
of the animal, and whether it represents a new animal or one that has been
sampled before. As more people become involved, the information will continue
growing and wildlife biologists will be able to determine that marten are
gaining ground and showing up in areas where there was once none.
Thanks to greatly improved land use planning, the
adoption of best management practices by trappers, wildlife management, and
public knowledge, marten distribution and abundance are increasing. However,
continued support for marten recovery efforts are needed. Intervale is helping
the Newfoundland Wildlife Division in this work through the continued efforts
of staff and volunteers, and by encouraging the best management practices among
forest users in general. For example, Intervale encourages the best practices among
snowshoe hare snarers, instructing trappers on how to build and use floating
mink box traps, giving presentations to youth and adults, and distributing
informational materials such as placemats. These educational efforts contribute
to fewer marten being accidentally caught in snares and traps. They also enable
people to learn more about how they can contribute to recovery of marten.
Brass Wire Snares
Did you know that different types of 22-gauge brass wire outperform others?
Best practices:
- Don't kink it
- Don't reuse it
- Make slips in field
- Check snares daily
- Remove snares after season ends
Movement
of the Red Back Vole
The
red back vole is one of the Newfoundland marten’s main food source. They are
dispersing across Newfoundland and have been spotted as far as Brigus Junction
in the east and as far north as Barr'd Harbour. It is believed that the quick
increase in the population is one of several factors helping the marten
population rebound.
How to
get Involved
Intervale
is currently looking for volunteers to participate in the hair snag program in
the following areas: South Branch, River
of Ponds, Hawke’s Bay, Main Brook, Lewisport, Carmenville, Musgrave Harbour,
Goobies, Badger, South Brook, Whitbourne and any of the surrounding areas. If
you are a walker, hiker, outdoor enthusiasts, hunter, trapper, or just want to
help the recovery of the Newfoundland Marten, e-mail us info@intervale.ca and we will get you started with
all the supplies you will need for the season.
