Lois Lindberg: “Shu Swmp Preserve and the Beaver Brook Watershed.”
Shu Swamp Preserve, officially the Charles T. Church Nature Sanctuary in Mill Neck, is a 60-acre jewel of the North Shore Wildlife Sanctuary system of preserves and is one component of the larger Beaver Brook Watershed. Acquisitions by Nassau County and the North Shore Land Alliance have added critical parcels that create a natural corridor to protect this valuable ecosystem. This program will explore the area’s beauty and biodiversity, especially highlighting the wildflowers and other flora of this special place. Lois has been involved in nature, ecology, and outdoor education and interpretation for many years. She has a degree in Biology from Hofstra University, and is a past Curator of Natural Science for Nassau County Department of Parks, Recreation & Museums, having worked at Muttontown, Welwyn, Sands Point, Garvies Point, and Tackapausha Preserves. She is currently the Membership Chair for the Long Island Botanical Society, and volunteers at Sagamore Hill National Historic Site in Oyster Bay as a naturalist/field trip leader.
Location: Bill Paterson Nature Center, Muttontown Preserve, East Norwich

Lisa Synoradzki: "Welwyn Preserve’s Forest: To Restore or Do Nothing.”
Years ago, "ancient," "magnificent," and “spectacular” were used to describe the 40-acre woodland in Welwyn Preserve, known for its grove of enormous oak and tulip trees. Today, sadly, invasive species, from creeping euonymus to Japanese knotweed, are spreading unchecked from adjacent yards, threatening to give the forest habitat a new descriptor, "degraded," if nothing is done. Lisa will talk about her study on Welwyn’s plants in the context of the ecological restoration debate. Lisa is Senior Development Officer at The New York Botanical Garden (NYBG). She has her Certificate in Botany from NYBG and is a certified NYBG Urban Naturalist.
Location: Bill Paterson Nature Center, Muttontown Preserve, East Norwich

Jeffrey E. Hudson and Gilbert N. Hanson: "Why are Plants Thriving in Spite of Acid Rain and Acid Soil?"
Due to acid rain, natural Long Island soils are depleted in the nutrient Calcium (Ca) and enriched in poisonous Aluminum (Al). In a limited study, the speakers found that Ca is restricted to the uppermost layer of the soil where there is less soluble Al. Could it be that plant roots are getting most of their nutrient Ca in that upper-most layer of soil where the Ca is derived from decaying plant litter and atmospheric dust? Gil Hanson is a Professor of Geology at Stony Brook University who spent most of his career in isotope and trace element geochemistry of rocks. In the last 20 years he has become more interested in the geology and ecology of Long Island. Jeff Hudson is a current Stony Brook Masters student in the Geo-science Department. He studied biology and science education and gained and interest in bio-geochemistry during his undergraduate degree. Between his undergraduate and graduate studies, Jeff was an educator and Peace Corps volunteer.
Gilbert N. Hanson: "The Natural Surface of Long Island is Covered by Pebbly Loess."
The uppermost layer of much of Long Island’s natural surface appears to consist of a dun-colored, unlayered, heterogenous, mixture of clay, silt, sand, and pebbles. This deposit is not directly related to glacial activity. The glaciers left Long Island some 20,000 years ago. At two sites, one on Stony Brook campus, dating gives ages of about 13,000 years for the time of its deposition. The hypothesis is that variations in the silt to sand ratio in this surficial layer are determining the type of soil and whether deciduous forest, pine barrens, or dwarf pine plains are found. The most important factor may be how small changes in the silt plus clay to sand ratio affects the infiltration rate of precipitation through soil.
Pre-Meeting Field trip to see Pebbly Loess: Meet at 6:30 PM at our regular meeting room. This field trip on the Stony Brook University Campus will be within a quarter of a mile of the Earth and Space Science Building where we will see the pebbly loess in an exposed section in a small stream valley and in forest soil. Walking total of about one-half mile along mostly paved areas.
Location: Museum of Long Island Natural Sciences, Earth and Space Science Building, Gil Hanson Room (Room 123), Stony Brook University, Stony Brook
