In recent years, the value and contribution of citizen science has been growing. The participation of people in collecting data through observations about the natural world increases both the volume of information on a subject as well as the dedication to and the understanding of the conservation issues in the citizen scientist. Bob Hirshon is a MD Master Naturalist, lifelong natural history fan, founder of Springtail Media and author of the citizen science chapter of the new Maryland Master Naturalist Handbook. He hosted and produced the podcast Citizen Science: Stories of Science We Can Do Together.

Fast fashion is a growing concern due to its detrimental effects on the environment. Poor quality clothing ends up landfills much sooner, the use of polyester and other synthetic materials has a large carbon footprint. The massive amounts of water and dye that are used to produce much more clothing than we need is unsustainable on a global level.

There are 30% fewer birds in North America than there were just a half-century ago. However, our very smallest feathered friend, the Ruby-throated Hummingbird can rather easily be attracted to our yards. Come learn about the extraordinary physical capabilities and migratory feats of these remarkable birds, the environmental challenges they still face, why they make such desirable neighbors, and what you can do to encourage the presence of these feisty and charismatic charmers in your own backyard! Brian Rollfinke earned a BS in Biology and an MS in Ecology with a focus on forest songbirds. Upon becoming an empty nester, Brian returned to his first passion, working as Director of Education at a local nature center for 3½ years and now, for the past 2 years, as Director of Education & Outreach at several Maryland stores in the Wild Birds Unlimited franchise.

Join us for an insightful presentation on the benefits of planting native species in the fall. Discover how fall planting reduces the need for watering, as cooler temperatures and increased rainfall support plant establishment. Learn about the cost-effectiveness of using plugs which allow plants to develop robust root systems over the winter. We'll also explore the advantages of direct seeding, particularly for species requiring cold stratification. Additionally, we'll discuss eco-friendly practices like "leaving the leaves" and creating "soft landings" to enhance biodiversity and provide habitat for local wildlife. Embrace the season and transform your landscape sustainably! Lisa Kuder is the UMD Extension representative for the Maryland Native Plants Program, a collaborative effort involving the Department of Agriculture, Department of Natural Resources, and the MD Native Plant Society. The program's primary goal is to enhance the appreciation, availability, and use of native plants in both natural and developed environments.
