At 2 pm Dr. Doug Tallamy, Professor & Chair of Entomology and Wildlife Ecology at U. of Delaware, will speak on native plant and insect interactions. Urban and suburban sprawl have replaced natural areas throughout the East, leaving suburbia as the primary living space for our biodiversity. If we want to sustain our natural heritage into the future, we must stop replacing native plants with alien ornamentals that most of our wildlife cannot eat, and start planting the native plant species that nourish our local biodiversity. Fortunately, this is easy to do and will be explained at the talk. At 3:00 pm Ed Perry, U. S. Fish and Wildlife, retired, will present his program: Spring Creek Canyon – Paradise Lost? He will discuss the values of the canyon for fish, wildlife and biodiversity, how habitat fragmentation adversely affects biodiversity, what we can do about it and how the failure to re-vegetate this property will facilitate the continued decline in Pennsylvania’s biodiversity. This is the PA Native Plant Society's Annual Meeting which starts at 1 pm. The public is welcome. Bring food to share if you desire and mug and cloth napkin to minimize our ecological footprint. Brief annual elections and business will be held at 1 pm. Dr. Tallamy is a LAN participant's favorite speaker on the importance of biodiversity. Come for any or all of the meeting.
