House Finch Eye Disease: Increased virulence as disease progresses

Usually, individual birds infected with a disease develop an “immune memory” that is used to help protect them from reinfection. It’s similar to when your body creates antibodies after you get sick or receive a vaccine. The antibodies help prevent reinfection by that same pathogen strain. However, since birds can’t walk into vaccine clinics, their immune memories are not always perfect, and we’re learning about this phenomenon from House Finch eye disease.

Pitch in a Patch for Pollinators

Presented by Habitat Network, The Nature Conservancy, and The Cornell Lab of Ornithology

This spring, Pitch in a Patch for Pollinators. We know pollinators need habitat to thrive–can you commit just a little more space for a new pollinator patch? Each of us has a role we can play in stitching together vibrant, healthy habitat for our butterflies, bees, birds, bats, and various other pollinating wildlife.

Analysis: Reinterpretation Of Migratory Bird Treaty Act Runs Counter To Spirit Of The Law

Over a century ago, then-Congressman John Lacey of Iowa observed of the Passenger Pigeon: “a single generation has seen them swept away.” He wrote at a time when other bird populations—egrets, herons, spoonbills, and more—faced decimation, slaughtered for their plumage. Bird populations once deemed so abundant by John James Audubon that he imagined their populations impossible to annihilate were imperiled. And the Passenger Pigeon, once numbering perhaps in the billions, went extinct.

The 19th Annual Chanticleer Lecture:
Claudia West presents Wild and Neat: Bridging the Gap Between Great Garden Design and Ecology

Sunday, April 29 at 3 PM
Location: Radnorshire Room at Radnor Township Building,
301 Iven Avenue, Wayne, PA 19087

Our planet is rapidly losing its foundation of life—the very plants that sustain us and most other creatures on earth. We know planting more na­tive plants in our gardens is an important part of the solution. However, many native plant gardens that focus on ecological benefits often suffer for aesthetic challenges and fail to inspire. Great plant­ing design is an essential part of the solution. Join us as we dig deeper into inspiring design principles derived from wild plant communities that resonate deeply within us and trigger stunning emotional re­sponses. We will analyze archetypal landscapes and translate their principles into smaller garden spac­es to help you create the native plant oasis of your dreams that will blow you away with stunning beau­ty!

Claudia West is a leading voice in the emerging field of ecological planting design. She has worked on all sides of the green industry—as a designer, a grower, installer, and land manager—grounding her innovative work in pragmatic solutions that address the realities of our urbanizing world. She is the co-author of the critically acclaimed book, Planting in a Post-Wild World.

This lecture is free and open to the public, and is sponsored by Chanticleer, a Pleasure Garden.
