People
and Loons: Sharing Michigan's Lakes
by:
Joanne C. Williams,
State
Coordinator MLPA/MLW
Michigan has many
beautiful natural treasures and one of them is the exquisite Common Loon.
Michigan Loonwatch (MLW) was begun in 1986, and the MLPA (Michigan Loon
Preservation Association) was formed in 1987 to help protect and preserve this
very special bird. We work together to monitor
loons and their habitat on lakes throughout our state, with the help of our over
400 volunteer Loon Rangers, Area Coordinators and others. We also work to
promote conservation of our beautiful lakes. This is important for Michigan, for our loons and other
waterbirds, and for people to
continue to enjoy and use our lakes into the future.
There are many
factors, both from nature and from human influence, that can affect loon nesting
success and survival. There is
sometimes little that can be done to help with many natural problems, although
we do install Artificial Nest Islands (ANI) on some lakes where loons have had
difficulty nesting because of
changing water levels and other
factors. The ANI are sometimes used
also on lakes where human influence has changed the loons' habitat.
One of the main
factors in human impact on lakes and loons, as well as other waterbirds, is the
use of watercraft on the lakes. MLPA/MLW
has developed a new Boating Education Program and brochure as part of our
efforts to reach Michigan boaters and lake users, to promote better
understanding of the needs of loons and other waterbirds and to speak for the
conservation of our beautiful lakes as we share this very special resource.
We have been awarded two grants, from the Michigan DNR Natural Heritage
Nongame Wildlife Fund and from the Audubon Society of Kalamazoo that together
will help with our new Program's implementation and evaluation.
Our new brochure
"Michigan's Loons and Responsible Watercraft Use" is being distributed
throughout the state at many
locations and events, including wildlife
programs and other educational presentations, and at nature centers, stores and
libraries and through mailings. It
is also being placed by our members and by other groups and agencies with which
we work, at marinas, boat launch areas and other places frequented by boat
owners and users, to a very favorable response.
If you are interested
in being part of Michigan's Loon Association and/or would like to help us in our
efforts to distribute brochures, monitor loons, or just would like more
information, you may visit our website www.MichiganLoons.org
Plan Now for Next Summer !
Since the beginning of our Michigan Loonwatch Program, an
important part of our protection efforts for the loons has been the use of
information buoys and Artificial Nesting Islands (ANI). Buoys have been used
when there is possible disturbance to the nest site area, and ANIs are used where
there has been degradation or loss of the nest site, of suitable habitat for a
nest site or where conditions such as predation have caused loons to lose the
nest, eggs or chicks. They can also be placed when it appears that loons have recently left a lake
because of inability to nest or to nest successfully, and also where loons have
nested in the past or when they appear to be "scouting out" a lake for
nesting and are unable to find a suitable area.
With the increase in development along the lakeshore areas
and the resulting decrease in loon nesting habitat, ANI are being considered for
placement more and more, and requests for them are increasing. Extra requests for
buoys are also being made as human lake use increases. Both buoys and ANI, when
used properly, can have a positive influence on the nesting success of the
loons and help provide for their survival.
INFORMATION BUOYS: Large information buoys can be floated
around the loon nesting area to warn boaters of the presence of loons. The DNR
Law Enforcement and Wildlife Divisions have designed a special loon information
buoy that is 61" long, 9" in diameter, And weighs 56 pounds. The buoy
has a loon silhouette and reads: "Do not enter- Loon Nesting Area."
These buoys have been used with good success. They are placed
only where there is a definite problem with human disturbance and where the buoys and nest
can be watched, Buoys are placed in a radius around the nest area, about 500 feet out from the
nest site, so boaters or personal watercraft users will see them well before entering the nest area. They should not be
used where they may draw attention to a nest and increase activity by birdwatchers, curious boaters
or fishermen.
These buoys cannot be placed without obtaining a permit
from the DNR District Law
Supervisor, and requires a new permit each year. The application will also be
reviewed by the District Fisheries and Wildlife Supervisors.
A Loon Buoy Protocol and Procedure packet with a permit copy
can be obtained from MLPA/ MLW. We also own a limited number of buoys. The buoys
cart be ordered from Smith & Nephew Roylan in Menominee Falls, WI.
NESTING PLATFORMS:
Artificial Nesting Islands (ANI), floating manmade platforms or rafts, can be
constructed of various materials. They can be made of wood, cedar logs or PVC
pipe. The frame is wrapped with wire or plastic mesh, and the ANI anchored
usually near a previous nesting site. They are relatively inexpensive and easy
to make, but usually do require hauling out each fall and replacement in the
spring. The wood or cedar log platforms are heavier than the PVC design, and
also must be replaced after several years as the logs become water-soaked and
deteriorate.
The PVC platform, designed by Area Coordinator Jeff Lange,
and tested for two years in a study partly funded by Michigan Natural Heritage,
is also well accepted by the loons and has been used successfully for several
years. It is much in favor for its light weight and ease of handling.
A permit is not required for the placement of an
ANI. However,
they may not obstruct waterways, and under the authority of the Marine Safety Act, they can
be
ordered to be relocated or removed by a Conservation Officer if considered to be a hazard.
MLPA/MLW has an ANI informational packet available with plans
for both cedar and PVC nest islands. If you think your lake needs an ANI, contact
us and we can help with information and to determine if and where a platform
might be useful. Platform materials and assistance in construction may also be
available.
