A new focus on silent sports

by Maria Kopecky, Outdoor Recreation and Events Specialist

This summer, we are excited to be increasing our support for silent sports in the Northwoods!  Silent sports are outdoor recreation activities that rely solely on self-propulsion.  These activities span all seasons and include hiking, running, canoeing, kayaking, mountain biking, road biking, snowshoeing, cross-country skiing, and multisport events (like our Just Tri It! triathlon).  

Silent sports have been gaining popularity in recent years among outdoor enthusiasts of all ages and ability levels.  Participants are committed to healthy living and a healthy environment.  They seek out intimate experiences with nature, yet are eager to share their passions with others.  Throughout the Midwest, silent sport communities have come together to explore and appreciate nature together.

The Manitowish Waters community has extraordinary silent sport resources for year-round enjoyment.  To encourage Northwoods residents and visitors to explore our area in new ways, we will be creating an inventory of local silent sport resources, establishing a new destination of our own, and leading a variety of silent sport activities throughout the summer.   Keep your eye out for future silent sport updates!

A Tree’s Story

By Courtney Davis, Environmental Education Intern

Our youth summer programming began last week. The topic was trees! 

Inspired by Aldo Leopold’s essay The Good Oak where he introduces annual tree rings as history books, students wrote creative stories about what they thought their “adopted” tree experienced in past years.  Our eco-discoverers also enjoyed making their very own 3-D tree. The eco-explorers got the chance to paddle in a homemade birch bark canoe. 

The students also spent time counting the annual rings of a 100 plus year old tree! They could not image the land 100 years ago. Their imagination ran wild!

Dragonfly emerges

by Licia Johnson, Naturalist

While visiting the Tenderfoot Reserve, a Nature Conservancy property with the Center for Conservation Leadership students, we came across a mass hatching of adult dragonflies.  We paddled three miles across Palmer Lake, up the Ontonagon River, and across Tenderfoot Lake to reach the property.  On the grasses of the shoreline we found many exoskeletons of dragonfly nymphs and the newly emerge dragonflies nearby.  This fella was on a spruce tree at the beginning of our trail hike.  He emerged not a moment too soon, as thousands of mosquitos swarmed the group!

Mushroom Powered Rockets?! Fun Facts about Fascinating Fungi

Ever year people scour the trails in Wisconsin’s north woods to forage for mushrooms with high hopes of bringing home some delicious earthy eats.  The Morel Mushroom is without a doubt one of the  most highly sought after fungi, not only is it quite tasty, the morel mushroom retails at $15-17 or more per pound to the right buyer or “fun guy”.  But, before you head out in to a local hardwood forest where these mushrooms can be harvested make sure you know what you are looking for because there is more than one look-a-like that can make you extremely sick.  One of these imposter morals is the Conifer False Morel (Brain Fungus), and this very distinctive spring mushroom (mid-May to mid-June in northern Wisconsin) grows at the same time of year and in the same habitat (sandy soil, under pine, spruce, and sometimes aspen) as the true morel.  Even with their similarities the distinctive red-brown brain like cap on the poisonous false morel mushroom is an easy way to tell the difference between the two.  You do not have to be a rocket scientist to identify this poisonous fungus in the wild but you might need to a rocket scientist to fully appreciate and understand the fascinating truth behind the Conifer false morel.   Scientific studies of this particular fungus has revealed that the presence of a carcinogenic toxin, monomethylhydrazine (MMH), is not only what causes the unpleasant symptoms to humans after ingesting it is used as a propellant for the rocket fuel in the Space Shuttle.

A Surge of Spurge!

A Surge of Spurge!

by Tim Dobbins, Summer Water Educator

Leafy spurge is a common terrestrial invasive plant located throughout many areas of Wisconsin. Its bluish-green stem containing alternating lance shaped leaves can assist in identifying this leafy plant. Throughout the early summer leafy spurge can be seen with yellow flower clusters located at the top of the stem. It prefers sunny areas with dry to very dry soil such as fields and along roadsides. 

As an invasive species, leafy spurge provides a threat to our endemic species. Each plant can release a toxic substance into the soil surrounding it to prevent the growth of any competing plant that may have occurred in that area. This allows the invasive plant to spread quickly and drown out native species. Leafy spurge has an extremely large root system and new plants can even sprout from root fragments making removal extremely difficult. To spread seeds, leafy spurge can open its seed capsules in an explosive manner sending seeds over 15 feet away!

If you look close you can see the forming of the seed capsules here!

As of July 2011 the Wisconsin Department of Natural Resources has 58 of Wisconsin’s 72 counties listed for known populations of leafy spurge. Vilas is among the 14 counties in which leafy spurge has not yet been documented as inhabiting an established population. 

However, earlier this week AIS Coordinator, Anne Kretschmann, and I spent the day on Island Lake taking water samples at different areas throughout lake. While boating over to one of our sample locations, Anne noticed a small cluster of yellow flowers along the shoreline. After collecting a small sample, we brought it back to the Discover Center and confirmed it was indeed leafy spurge. Our next step is filling out a Wisconsin Department of Natural Resources Invasive Plant Report.

Here is one of the infestations found on Island Lake.
