NIDRM is more than just maps: It is a nationwide, science-based, administrative planning tool that is the product of a process whereby, every five years, the forest health community works together to determine the severity and extent of tree-mortality hazard due to insects and diseases. NIDRM represents 186 individual insect and disease hazard models, integrated within a common GIS-based, multi-criteria framework that can account for regional variations in forest health. Applied to all 50 states, and based on the best-available science and data, NIDRM’s modeling process provides a consistent, repeatable, transparent, and peer reviewed process through which interactive spatial and temporal hazard assessments can be conducted. NIDRM allows for flexible analysis to produce hazard assessments for specific insects and diseases, and can and is being used to inform other agency assessments such as the Integrated Resource Restoration, Watershed Condition Framework, Terrestrial Ecosystem Condition Assessment, Existing Vegetation Classification Mapping, and Inventory, and Hazardous Fuels Prioritization Allocation System.
Japanese knotweed, now a state prohibited plant, is spreading explosively in some areas of southern Michigan. Due to its attractiveness in flower and former intentional planting in many landscapes as a cultivar, the insidiousness and particular challenges of managing this plant are often not recognized until infestations are extensive. Common first approaches like using over-the-counter herbicides and pruning or mowing can actually stimulate its spread. Effective treatments for Japanese knotweed ARE available and involve a combination of community and municipality education and using the right herbicides at the right time. We will present lessons learned and successes in managing Japanese knotweed in Ingham and Clinton Counties, which have taught us how to manage other invasive species more effectively, too!
El Niño is a natural warming of the waters in the equatorial Eastern Pacific that causes major influences on winter weather patterns across much of the globe, particularly in North America. With one of the strongest El Niño events ever recorded currently in progress, Dr. Masters will discuss how such events have influenced past winter weather in the U.S. He will also discuss how the event will affect this winter's weather--keeping in mind that global warming is likely to bring Earth its warmest winter on record this winter and bring jet stream patterns capable of causing periods of intense cold and snow to eastern North America.
Projected climate change may pose challenges to the long-term stability of our forests, so it is important for forest landowners to consider their particular risks, opportunities, and ways to adapt.
Volunteers are key to most stewardship programs. We’ll look at volunteer programs from both sides.
In this webcast, we will highlight control techniques available for small scale projects, which are not normally available for use on large scale projects. Homeowners and land stewards should be aware of these techniques, and use them to get the best possible results from their management efforts.
Using megafauna like raptors or birds of prey is the perfect way to get a community's attention. Once you have their attention the directions you can go are limitless. During this webcast, learn how to link conservation success stories of flagship species like bald eagles or the back yard hunting prowess of eastern screech owls to the broad range of conservation issues we face today. Presentation tips, techniques and examples of story flow will help you communicate your message and engage your community in your conservation efforts.
Prescribed fire is an effective management tool frequently used to alter, maintain, and restore vegetative communities throughout Michigan. It is also a tool that can negatively impact Eastern box turtle populations. There are several natural history and behavioral conflicts that make reducing the negative effects of prescribed fire on box turtles challenging. Box turtles are slow-moving, their active season overlaps the burning season, they tend to hide in high fuel loads, and their movement patterns are variable and uncoordinated. Evaluating and utilizing the strengths and weaknesses of your site (such as water sources and available nesting areas), rotating burns between seasons, and using the longest burn interval possible will be important in reducing the negative impacts of prescribed fire on box turtles.
