There is a fairly well understood relationship between the soil and vegetation types that grow. John Lanier, with nearly 40 years experience in wildlife habitat and species management, and Brendan Prusik, with over 20 years experience in forestry, have developed a tool that’s relatively simple to use to help land managers, owners, and planners practically apply the relationship between soils and vegetation. Starting with the soil, a person can identify the potential for re-vegetation and use by wildlife.
Rooted in the eleven major forest types in the northeast, it is possible to generate a host of the wildlife species that prefer a particular forest type for breeding. By incorporating a diverse body of information and research and distilling this information into a simple, useable format, landowners and land managers have a powerful tool to aid them in their decisions about which plant and animal species to manage for. This has profound implications for species of greatest conservation need and corresponding management practices.
We investigate the effects of dam removal and ask if the removal of the dam has resulted in recovery? Can we distinguish the effects of dam removal from the effects of the droughts? Furthermore, do the benthic aquatic invertebrates respond in the same way that the fishes do to dam removal and drought? Can the structure of the fish community be predicted from the structure of the invertebrate community? I will use the results to get us to think about dam removal as a “one-size-fits-all” approach.
Crazy Worm (Amynthas agrestis) is an invasive earthworm native to East Asia. This active and damaging pest was found in Wisconsin in 2013. It is known and sold under a variety of common names including Crazy Worms, Alabama Jumpers and Snake Worms; and the name speaks for itself! They act crazy, jump and thrash when handled, and behave more like a threatened snake than a worm. Learn more about this invasive worm in this informative webcast!
In the United States more than 200,000 miles of waterways have been modified to trapezoidal-shaped drainage ditches benefiting more than 110 million acres of agricultural land at an estimated cost of $56 billion dollars. Agricultural ditches are designed to remove excess water from fields and prevent flooding onto fields. Researchers at the Ohio Agricultural Research & Development Center (OARDC) have developed a new "two-stage" ditch design. The new design has a small main channel at the bottom of the ditch - stage one - and grass-covered "benches" along the sides of the channel - stage two. Check out this webcast to learn about this game-changer for ditch design!
The Center for Invasive Species and Ecosystem Health has built a suite of tools for reporting, identification and management of invasive species and other pests using smartphone applications. This webcast will primarily focus on the new Great Lakes Early Detection Network app which includes identification and reporting of all taxa of invasive species, allows drawing of polygons and reporting of negative surveys. We will also highlight some of the latest apps with identification keys and decision support tools as well as directions for future apps. If you want to learn about smartphone apps for nature, this is it!
With The Stewardship Network's annual Garlic Mustard Challenge underway, it's a great time to discuss this herbaceous invasive! Garlic mustard takes over our woodlands and out competes native wildflowers and tree seedlings, threatening biodiversity and forest regeneration. It's been creeping its way across the continent, and can now be found in many parts of the U.S. and Canada. Join us for an overview of the biology of garlic mustard, emphasizing critical stages for management. Multiple management methods (mechanical, manual, and chemical), will be discussed, including when and where it is appropriate to conduct each method. We will also discuss the positive impact of multi-year management, and organizing and engaging volunteers to help in our efforts. Many hands make light work, and many trained eyes help us get a bigger picture of where invasive plants are in our communities.
Great Cities, Great Lakes, Great Basin. The watershed of the Great Lakes, St. Lawrence River, and Gulf of St. Lawrence - the Great Basin - spans from Duluth, MN to the Atlantic Ocean and is home to more than 50 million people. Despite hundreds of important efforts to clean and protect the Great Lakes and St. Lawrence River, none addressed the binational waterways and their surrounding lands comprehensively, as a whole ecosystem. The Great Lakes Century Vision changes this - watch this webcast to learn about this revolutionary vision for the Great Lakes and our communities!
The New Hampshire Dragonfly Survey was a citizen science project conducted in 2007-2011 as a partnership between NH Audubon and the NH Fish and Game Department. Over the course of the survey, over 200 volunteers were trained in dragonfly identification and survey methodology, and over 100 people eventually submitted data. Their collected efforts yielded over 18,000 records of 157 species and generated roughly $150,000 dollars of in-kind match. Learn about this powerful program in this month's webcast!
