Introduction The US Committee of the North American Bird Conservation Initiative (NABCI) published its State of the Birds 2022 report last fall. Among its key findings is a list of birds whose populations have fallen by half between 1970–2019, […]
Project: Due to the loss of the ash tree as a functional member of the forest, large gaps have been created in the canopy; due to the severe deer pressure and quick spread of invasive species, native seedlings need our protection. Join us at our Fuller-Pursell Preserve as we seek native, naturally-regenerating seedlings to either […]
Project: Invasive species threaten our native plants by crowding them out and outcompeting them for resources. They also have the added benefit of being unencumbered by diseases, parasites, and herbivores. Join us as we work to remove them from around our native plants to give them the space they need to thrive. Work level: Easy […]
We’ve reached the depths of summer, as evidenced by intense waves of heat and humidity. Solace from our powerful sun awaits beneath the shade of trees, and lucky for us, interesting organisms exist there too. Mushrooms occupy the forest floors throughout the year, but in late summer – and even more so in early fall […]

Mountain laurels (Kalmia latifolia) blooming on one of Heritage Conservancy’s properties. Mountain laurels are gorgeous shrubs that have been Pennsylvania’s state flower since 1933. It is one of the few evergreen shrubs that is native to Pennsylvania, however it is very widespread across the state. It is in the heath family living on drier, more […]
Project: Once upon a time, this mine had the largest colony of bats in eastern Pennsylvania. Unfortunately, white-nose syndrome has decimated the population to a tiny fraction of what it once was. However, the bats will return! Populations in other parts of the world, struck down by white-nose, are starting to rebound – albeit slowly. […]
We gathered together with community members, volunteers, local partners, and specialists to learn about Croydon Woods. We had a magnificent turnout at our BioBlitz Celebration on Friday, May 19th, as we gathered together to celebrate our BioBlitz survey – a private 24-hour scientific survey of plants and animals. The celebration served as a reminder of […]
