3rd Edition of Walking Paths & Protected Areas of the Keweenaw

Walking Paths cover

Walking Paths & Protected Areas of the Keweenaw is a guide that features publicly accessible nature and wildlife sanctuaries, preserves, and parks located in Houghton and Keweenaw Counties on Michigan’s Keweenaw Peninsula that have been protected through citizen action and private initiative.

These special places provide both residents and visitors the opportunity to encounter a variety of native habitats, interesting plant species, and unique geological features in this nothernmost part of Michigan, as well as a glimpse of Michigan before European settlement and the nineteenth century copper boom. These are places where natural processes can unfold with minimal human interruption or alteration.

The Upper Peninsula’s abundance of waterfalls

Besides being the Great Lakes State, another unique thing that attracts people to Michigan is the hundreds of waterfalls all around the Upper Peninsula.

Despite the fact that there are so many waterfalls in the UP, surprisingly there are only a few in the Lower Peninsula.

Most Michiganders know the story of how the Great Lakes were created; after an ice age, the melting process began, with some glaciers being extremely dense and thick, gouging holes into the earth. These gouges formed the Great Lakes as they are today after the glaciers finally melted away and the land became populated with plants, animals and people.

The Upper Peninsula’s waterfalls are made up of sandstone and were formed over thousands of years. Much of the formation is due to how water falls over or on top of the rock that makes it up. Water erodes the rock over time and can create ridges and falls and a water basin by wearing down soft rock. The water basin at the bottom of the falls where water is collected.

Some waterfalls are more cascading, others have more of a sharp drop-off and some are considered rapids because of their location and how water flows.

MNA boasts the Twin Waterfalls Plant Preserve Nature Sanctuary in Alger County. The sanctuary was acquired in 1986 in honor of MNA member Rudy Olson. The Munising Formation is also an exquisite part of the sanctuary, making up the vertical walls of the waterfalls. This formation is made of 550-million year old sandstone which is soft and erodes more quickly. The sandstone of the upper-rock which caps the formation is made of harder sandstone, which takes much longer to erode and makes up the Au Train Formation. This slower rate of erosion results in the shelf over which the water drops.

MNA Volunteer Days: Red Cedar River Plant Preserve

The Red Cedar River Plant Preserve is more than just a 10-acre sanctuary in Williamston, Michigan, and the only one in Ingham County. This sanctuary is one of five MNA sanctuaries within the boundaries of a city and is close to the MNA’s former headquarters.

Usually land within cities has been far too degraded for MNA to claim as a sanctuary, but because of the floodplains within the Red Cedar River Plant Preserve, this area has surprisingly maintained its natural character so close to an urban area. This sanctuary was historically known as the Williamston Floodplain.

The sanctuary consists of floodplains and wetlands because it is so close to the Red Cedar River. There are also marshy and swamp-like areas as well.

These habitats are home to plant-life like marsh marigold, skunk cabbage and jewelweed. Some types of trees that grow on the floodplain ridge are black cherry and red oak. The ridge is welcoming to visitors, giving them a place to walk and explore during spring flooding season.

This sanctuary is one of the few that MNA has built a boardwalk on and it is one of the longest and the only with an observation deck included in its design.

The area was donated in 2005 by Doug and Darlene Price, who with the help of engineer David Geyer have worked on protecting important parts of the habitat. MNA collaborated with them to change the future plans of the development of uplands in order to preserve the area within the sanctuary.

The redevelopment of the sanctuary’s boardwalk will help protect the floodplain. The old design could not withstand the severe flooding so MNA has organized volunteer days to rebuild the boardwalk with a design engineered to allow it to be more stable and provide more access to the sanctuary. About 40 feet of the boardwalk must be built this year of a total of 150 feet, and MNA is enlisting all the help it can get.

MNA extends its gratitude to engineers Jim Rossman  and Paul Rice for volunteering their time to develop the design, cost estimates and construction phases, and stewards Jim and Besty Pifer who assisted in the planning process.

Upcoming Volunteer Days:

  • Thursday, July 10 at 9 a.m.
  • Thursday, July 24 at 9 a.m.
  • Wednesday, August 20 at 9 a.m.
  • Thursday, September 11 at 10 a.m.
  • Thursday, September 18 at 10 a.m.

Uprooting invasive knapweed

MNA is hosting several stewardship events this summer to remove the invasive knapweed plant from various sanctuaries.

The invasion of knapweed poses a danger to native plant life and must be uprooted. The knapweed’s origins are traced back to southeastern Europe. The plant begins to grow as a rosette of leaves in its first year of life and then later on grows a flower stalk ranging from six to 36 inches in height. The flower is usually pink or purple in color with a spotted head underneath, as knapweed is also referred to as “spotted knapweed.”

Knapweed can be found in well-drained soils, dry prairies and dunes. Knapweed is especially harmful to oak barrens, which are endangered worldwide.

The weed’s invasion has caused a decline in native plant species, which is threatening to the ecosystem. It can also alter water quality by causing an increase in soil runoff and erosion.

Two common ways of eliminating knapweed are simply pulling the plants or mowing them down. There are also herbicides and chemicals that can also be used for removal but have several regulations and must be used carefully as to not upset any other plant or wildlife.

Two different insects have also been introduced to inhibit the knapweed from spreading seeds: flower weevils and seedhead flies. These insects introduced to the knapweed are a form of biological control of the invasive species.

Of these methods, MNA has most commonly uprooted the weed. Uprooting sounds much easier than it is, involving tools to help pull as many of the knapweed’s roots out of the soil as possible. If left behind, the roots could help the weed grow again and damage native plant life.

The knapweed has a tendency to knock out all other vegetation surrounding it, making many ecosystems bare if it isn’t removed.

MNA has also used prescribed burns and herbicide to remove larger amounts of knapweed in sanctuaries. Simply pulling knapweed when it is extremely abundant wouldn’t prove effective; burns and chemicals have helped to reduce the occurrence of the plant.

MNA is calling for volunteers to help pull spotted knapweed from different sanctuaries. The next pull will be hosted at the Calla Burr Nature Sanctuary in Oakland County on July 10 from 9 a.m. to 1 p.m.

More upcoming knapweed removal events:

  •  July 22: Volunteer Day: Lefglen Nature Sanctuary in Jackson County. 9 a.m. – 1 p.m.
  • July 25: Spotted Knapweed Pull at Calla Burr in Oakland County. Begins 9 a.m.
  • July 26: Spotted Knapweed Pull at Keweenaw Shores II Plant Preserve in Keweenaw County with Nancy Leonard. Begins 11 a.m.
