Hemlock woolly adelgid is a small yet dangerous invasive insect that has become a big problem for hemlocks in Michigan and beyond. You can learn more about the species on Michigan.gov's website: https://www.michigan.gov/invasives/0,5664,7-324-68002_71241-367635--,00.html
Our guests this month are John Bedford (Michigan Department of Agriculture and Rural Development) and Greg Norwood (Michigan DNR). Topics covered will include:
"Volunteers are key to most stewardship programs. During this webcast we’ll look at: How does the organization develop and maintain their volunteer program? We’ll be discussing how to run a stellar volunteer program for your organization, your impact, and your volunteers; how to evaluate and communicate what your volunteer program has to offer in order to recruit the best volunteers for the job; and how to match the best volunteer opportunity for your volunteers."
"This is the first book of its kind to bring forward the rich tradition of wild rice in Michigan and its importance to the Anishinaabek people who live there. Manoomin: The Story of Wild Rice in Michigan focuses on the history, culture, biology, economics, and spirituality surrounding this sacred plant. The story travels through time from the days before European colonization and winds its way forward in and out of the logging and industrialization eras. It weaves between the worlds of the Anishinaabek and the colonizers, contrasting their different perspectives and divergent relationships with Manoomin. Barton discusses historic wild rice beds that once existed in Michigan, why many disappeared, and the efforts of tribal and nontribal people with a common goal of restoring and protecting Manoomin across the landscape."
"The northern forests from Minnesota to New England have no native earthworms. European earthworms have invaded many of these forests, where they transform soil structure by consuming the organic horizon (aka duff layer) and compacting the A horizon. These changes in soil structure lead to alterations in nutrient and water cycles within the soil. There are many important ecological cascades emanating from these invasions, including concerns for conservation of native plant and wildlife species, losses of forest and crop productivity, facilitation of invasive plant species such as buckthorn and garlic mustard, and soil and water quality."
This month's topic is: "Garlic Mustard - 3 Tactics to Take it Out," with our guest Chuck Pearson, a key volunteer actively engaged in ecological restoration at The Nature Conservancy's Ives Road Fen in Tecumseh, MI.
"I have been working at the Ives Road Fen Preserve since 1999, leading a group of volunteers in removing invasives from and keeping them from returning to more than 450 acres of fen, forest, and upland. Invasives that we deal with include garlic mustard, dame’s rocket, glossy buckthorn, honeysuckle, phragmites, and cattail. We also plant native seeds to accelerate the return of native flora in former agricultural fields. The result is a wildflower wonderland that supports a wide diversity of native animals, and provides nourishment for the soul for visitors to the preserve."
Chuck will share unique insights in these key areas of garlic mustard control:
1) Herbicide Use: All the why's and how's of herbicide use.
2) Brushcutter Use: You've probably never heard of using a brushcutter for garlic mustard. Here’s how!
3) Ecological disposal: No plastic bag purchases or shipments to the landfill from our operation.
4) Follow-up Frequency: You are wasting your time if you only visit an area once.
Sustaining oak forests and restoring oak savannas and woodlands are increasingly common management goals in the Midwest and Great Lakes Regions. Sustaining oak forests requires successful regeneration and recruitment into the overstory. The regeneration potential of oak following a disturbance or harvest that initiates stand regeneration is determined largely by the size structure of oak before the event. Collectively, regeneration from (1) seed, (2) advance reproduction, and (3) stump sprouts contribute to oak regeneration but vary in their competitive capacity. Oak regeneration potential is modified by site, competitor regeneration potential and management input.
Prescribed fire is increasingly being used to promote oak regeneration with mixed results, and it is required to restore oak savannas and woodlands. Oak has many silvical traits that make it well adapted to fire. Fire can promote oak regeneration, but it also can reduce it, promote competing vegetation including invasive species, and retard oak recruitment into the overstory. Fire is a tool that can be used to sustain oak forests if it is applied judiciously with knowledge of oak forest ecology and stand dynamics, and with basic forest inventory information. Combining prescribed fire with thinning or harvesting can be effective in increasing oak regeneration potential and dominance in future stands, and it is a good approach to accelerating the restoration of oak savannas and woodlands.
Many of the issues humans are currently struggling with have been sustainably negotiated by natural systems for millions of years. By studying nature’s patterns, processes, and relationships, we have the opportunity to gain insight into the effectiveness and sustainability of our own behaviors.
Many contemporary human group decisions appear to generate controversy. We will discuss aspects of group decision-making in nature, such as group cohesion and determination of appropriate deciders, and consider how these concepts can be applied to human situations. We will conclude by looking at examples of decision-making in small and large human group settings.
We will talk with Jeremy Solin, who works with ThinkWater in Wisconsin, and Eric Olson, the Director of the UW Extension Lakes, as well as our moderator, Lisa Brush of the Stewardship Network.
"Where you find lakes, you will also find lake organizations. Largely composed of shoreland home and cabin owners, lake associations and lake districts often fuel and lead efforts to protect lakes and restore water quality. The Wisconsin Lakes Partnership has developed a forty-year track record of providing state funding and assistance to aid lake groups in their efforts. This past year, researchers and
Wisconsin DNR staff stepped back to use system thinking tools provided by the ThinkWater School to reexamine the Lakes Partnership model and consider new educational tools to increase the effectiveness of local partners. This presentation will give a short overview of the ThinkWater approach to wicked problem solving, including the online system mapping tool, Kingfisher. We will also highlight some of the specific capacity development tools that UW Extension is creating using ThinkWater to facilitate on the ground success in protecting and restoring lakes."
