Biocontrol of Invasive Plants: procedures, safety, and effectivenessInvasive plants pose a threat to the ecological integrity of natural and restored ecosystems. Depending on the plant and its state of invasion, appropriate techniques for control range from hand pulling to herbicide sprays. But what do you do when conventional controls have failed and tens of thousands of acres are infested? This webcast will focus on the science and practice of weed biocontrol, i.e. the use of a plant’s natural enemies (herbivores, pathogens) to control its population growth and spread. The presentation will review the research, decision-making, and regulatory processes with an emphasis on evaluating the environmental safety of biological control. We will also update participants on the status of purple loosestrife, garlic mustard, and spotted knapweed biological control efforts in Michigan.
In 2009 three townships, three conservancies, and a county park system came together under the umbrella of a local Stewardship Network Cluster to begin mapping and managing invasive swallow-wort on protected and private lands of ecological significance within the Shiawassee Basin in Oakland County, MI. Several field seasons, land-owner outreach sessions, and grant applications later, we share our lessons learned. Presented by Heather Huffstutler, Stewardship Director, Six Rivers Regional Land Conservancy, and Brittany Bird, Natural Resources Planner, Oakland County Parks and Recreation.
It's that time of year again! Join us as we officially kick of the 2012 Garlic Mustard Challenge with our April webcast. Mark Renz will be joining us to give an overview of the biology of garlic mustard, emphasizing critical stages for management. Multiple management methods (Mechanical, hand removal, cultural and herbicide) will be discussed including a discussion of when and where it is appropriate to conduct each method. Tina Roselle, our Volunteer Garlic Mustard Challenge Coordinator, will also be joining us to talk about this year's Challenge, our goals, and what's new from previous years.
Donna will present on the Greening Corporate Grounds Program and other resources to aid businesses and institutions with outdoor greening on their lands. She'll discuss the many benefits of greening practices and its contribution to broader issues such as corporate responsibility. Donna will present on case studies from the program and conclude with an overview of expansion plans and the tools available to others with similar goals.
Almost all environmental issues in our complex modern society involve some form of conflict. Ed Sketch, an experienced conflict professional, wants to change this. He has used his over 30 years of conflict experience in the auto industry to develop a systematic approach to conflict handling, which also encourages us to see conflict as potentially creative. He will present an overview of his Creative Conflict Model in this webcast and discuss its application to environmental issues.
The Great Lakes hold a full 20% of the world's fresh water. It's an incredible resource, and an incredible responsibility. As residents of the Lake States, it's up to us to care for this amazing resource. Out West, water is managed through Water Rights law. How do we manage our own abundance of fresh water, and what are the implications of our actions and decision for our region and beyond? What are the various ways we may choose to steward this precious natural resource into the future? We will explore this topic from several perspectives with the help of our guest presenters.
The coastal sand dunes along the Eastern Coast of Lake Michigan make up the largest collection of freshwater coastal dunes in the world. Our studies of these dunes give us valuable information that will help us manage and protect them and yields important insights into both the development of coastal dunes in general and climate change in Michigan over the last 5000 years. In order to create a history of the Lake Michigan dune complex, we need to know when the dunes began forming, the timing of the various episodes of dune growth and migration, the ways in which these events changed the geometry and position of the dunes.
Nonnative invasive species present what may be the greatest threat to the long-term health and sustainability of Wisconsin's forests. To respond to this threat, the Wisconsin Council on Forestry created the Forestry Invasives Leadership Team to develop voluntary best management practices (BMPs) to help limit the introduction and spread of invasive species. Tune in and join Thomas Boos to hear about our successes in developing and implementing these best management practices on a State-wide level! Find out how easy it is for your state to adopt these BMPs and collaborate on regional outreach effort.
