Presented by Carolyn Klaube, The Sourland Conservancy
On rainy nights in early spring, thousands of frogs and salamanders embark on an ancient journey to their natal vernal pools. Learn about these charismatic forest dwellers, the important role they play in our ecosystem and the simple steps we all can take to help protect them. Carolyn Klaube, the Sourland Conservancy’s stewardship director, will share surprising details about spotted salamanders and the Conservancy’s Amphibian Crossing Guards program.

Carolyn oversees the Sourland Conservancy’s amphibian crossing guard program, stream monitoring and native habitat restoration efforts. She is passionate about involving the public in restoration ecology and building partnerships with other organizations, municipalities and counties to collaborate on projects to protect the Sourlands.
Presented by Jamie Boyer, Ph.D., New York Botanical Garden
Plants began their existence on land nearly 500 million years ago, and from humble beginnings, new species and landscapes evolved on the Earth, eventually creating the world we know today. In this talk we will take a journey through time to explore the evolution of ecosystems and the plants that define them, beginning with the earliest marshes to coal age rainforests and swamps and to a drying world with gymnosperm forests and deserts. With the dawn of flowering plants, 130 million years ago, we will explore the origin of temperate deciduous forests, the dawn of grasslands, the recent ice ages and the dawn of the tundra and boreal forests ecosystems.
Jamie Boyer, Ph.D. is a botanist, paleontologist and educator in the New York City area. He earned an M.Sc. in plant biology from Southern Illinois University, Carbondale, where he reinterpreted some of the earliest trees known from the fossil record. Fossilized stumps of these “Gilboa trees” are located in the Catskill Mountains. Boyer later earned a Ph.D. in plant biology from the State University of New York, Binghamton, where he investigated the evolutionary changes in plants during the Silurian and Devonian Periods. Currently, he is a vice president at the New York Botanical Garden, where he oversees all aspects of the Garden’s student, teacher, teen, family, special needs, service-learning and veterans’ programs.
Presented by Joan Maloof, Old Growth Forest Network
An old-growth forest is one that has formed naturally over a long period of time with little or no disturbance from humankind. They are increasingly rare and largely misunderstood. This evocative and accessible program defines old-growth and provides a brief history of forests. It offers a rare view into how the lifeforms in an ancient, undisturbed forest—including not only its majestic trees but also its insects, plant life, fungi and mammals—differ from the lifeforms in a forest manipulated by humans. What emerges is a portrait of a beautiful, intricate and fragile ecosystem that now exists only in scattered fragments. In this program, Joan Maloof, Ph.D., director of the Old-Growth Forest Network, makes a heartfelt and passionate case for the importance of these ecosystems.
Joan Maloof is a writer, ecologist and conservationist with a unique voice. She is a professor emeritus at Salisbury University, where she taught biological sciences and environmental studies. Maloof has published numerous research articles in publications such as Ecology, American Journal of Botany and the International Journal of Environmental Studies. Maloof’s books include Teaching the Trees (2005), Among the Ancients (2011), Nature’s Temples: the Complex World of Old-Growth Forests (2016), The Living Forest: A Visual Journey into the Heart of the Woods (2017) and Treepedia: A Brief Compendium of Arboreal Lore (2021).
Maloof is the founder and executive director of the Old-Growth Forest Network, an organization dedicated to creating a network of at least one protected forest in every U.S. county where trees grow. With nearly 4,500 supporters, the network now includes 147 preserved forests in 28 different states—including Bucks County’s Hart’s Woods, which is jointly protected by Doylestown Township and the Heritage Conservancy.
Presented by Diane Allison, North American Bluebird Society
Join us as we look at the ways that you can help Eastern bluebirds and other native cavity nesters remain numerous in our communities. This program explores proper nest box construction and placement for Eastern bluebirds. We will also discuss nest box predators, other birds that will use your boxes, how to care for the boxes and nesting behavior and timetables.
Diane Allison is a member of the North American Bluebird Society’s speaker’s bureau and has built over 2,000 bluebird boxes with school children and scouts. She has been the nestbox monitor for Giving Pond State Park, a part of Delaware Canal State Park, for nearly 15 years.

Presented by Juanita Hummel, BHWP & Washington Crossing Audubon
If you want to attract birds to your garden, you can put up bird feeders—or you can use native plants to provide food that will attract and feed birds year-round. While recent reports of bird feeders potentially spreading illness to the birds that patronize them are not always firmly rooted in factual data, there is a lot to be said about welcoming birds to our yards with a banquet of food that can be safely and naturally provided by native plants and trees. This talk is an introduction to what food various species of birds are seeking when they come to your garden at different times of the year, and how to satisfy that need for nourishment naturally—with a few tips on how to supplement that food supply using feeders.
Juanita Hummel is a retired research scientist who has been an avid birder for more than 40 years. She is currently the board president of the Washington Crossing Audubon Society in NJ, is a Pennsylvania master naturalist and a volunteer naturalist at Bowman’s Hill Wildflower Preserve.
