Isle Royale is a remote wilderness island, isolated by the frigid waters of Lake Superior, and home to populations of wolves and moose. As predator and prey, their lives and deaths are linked in a drama that is timeless and historic. Their lives are historic because we have been documenting their lives for more than five decades. This research project is the longest continuous study of any predator-prey system in the world. The purposes of this project are to better understand the ecology of predation and what that knowledge can teach us about our relationship with nature. Much of what we have learned is associated with having been patient enough to observe and study the fluctuations in wolf and moose abundances. John will present an overview of over 5 decades of research.
The topic of this month’s webinar is on mute swans in Michigan. It includes the history of mute swans in the state, their impacts on native birds, the environment, and people, and the management strategy of the Michigan Department of Natural Resources (MDNR). The MDNR has a policy in place to allow landowners to manage the mute swan populations on their property by obtaining a permit. The application process will be discussed. Also, a stakeholder who has gone through the process of obtaining a permit for his lake, will be online to provide a perspective from the landowner’s point of view.
This webinar will review and recap the latest applications and lessons learned by Applied Ecological Services, Inc. (AES) in aerial imagery, remote sensing and aerial photo interpretation. AES is using a Leica RCD 30, high-resolution, multi-spectral camera, as a cost effective means of monitoring and evaluating lands for comprehensive restoration planning. By combining the imaging technology with AES’ acute understanding of seasonal phenology and vegetation response to changing conditions image applications have focused on the seasonal calendar of opportunity. You will see a number of example applications and how they are tied to the seasonal calendar. You will also gain an understanding of how image resolution and utilization of the infrared data contribute to mapping things like: aquatic and terrestrial vegetation types, storm damage, ownership boundary encroachment, hydrologic change, farmed wetlands, point/non-point source impacts, invasive species distribution, impervious cover, tree canopy, agricultural crop production and much, much more.
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.
