If you want to start or improve your wildflower identification skills, springtime is a great season to start, since there are fewer species to learn and many are distinctive. The most spectacular wildflower displays in our area are in our woodlands in spring. Many of these flowers are ephemeral, appearing for a short time each spring, so timing to observe them is […]

Each spring, as snowmelt and seasonal rains gather in shallow forest depressions, a hidden world awakens. Vernal pools, temporary wetlands that appear and vanish with the seasons, become vibrant nurseries for some of Maryland’s most fascinating amphibians and reptiles. This talk explores the ecology, biodiversity, complex food webs, and conservation importance of vernal pools in […]
Nearly 35 million years ago a meteor or asteroid crashed into the Chesapeake Bay on the east coast of the United States creating a 12 mile wide crater. The last stage of the eocene, early mammals roamed the Earth when the mid-Atlantic coast had a tropical climate and vegetation.

After 40 years as a paleontologist, Dr. Lucy E. Edwards retired from the U.S. Geological Survey. Lucy attributes her success to a combination of being in the right place at the right time, a lot of hard work, and a brain that just happened to be wired to think like a paleontologist. The fossils she studies are the cysts of […]
April is Maryland Archeology Month! This year’s theme is 250 Years, Many Voices: Digging into Maryland’s Story. To go along with the theme this months Archaeology club meeting will be a presentation from Stephanie Soder a Research Archaeologist for the Maryland Historical Trust on the Washington-Rochambeau Military Encampments from the Revolutionary war. In the fall of […]
Plant-eating plants, or parasitic plants, are among the most misunderstood and fascinating members of the plant kingdom. In this presentation, Dr. Vanessa Beauchamp of Towson University introduces the remarkable diversity of plants that survive by tapping directly into other organisms for resources. This talk will explore how parasitic plants live and how they locate and establish connections with […]
Naturalist is much more than an ID app on your phone. Join us for an in-depth look at how to use the web-based features of iNaturalist to enhance your study and enjoyment of Lepidoptera, our fascinating butterflies and moths. Learn how to determine when and where different species are active, discover species you may not […]
Maryland is home to at least sixteen native species of freshwater mussels, though that number continues to shift as taxonomic work refines our understanding. These species occur statewide in a wide range of aquatic habitats, and identification can be challenging. Key features often lie inside the shell, and many species show significant variation in shape and […]
The Earth has a long history, and for most of the time has supported life. We will probe the depths of geological time and how life evolved into its current state. Recent advances in microbiology have suggested that eukaryotic cells (those with nuclei) were a logical and even likely outgrowth of evolution in a group […]
Agricultural drainage ditches are essential for water management on farms with high water tables, including those on the Delmarva Peninsula. These seemingly mundane agricultural infrastructures are home to insect biodiversity that provides valuable ecosystem services,such as pollination, biological control of pests, decomposition of plant and animal matter, and food support for wildlife. In this presentation, we will learn about phosphorous sequestration by tube-dwelling, non-biting […]
