Rocks, Soil, and Plants

Our morning talk will focus on the role of an area's underlying rocks on soil formation. It will cover the constituents and type of soils. Emphasis will be placed on all the organisms present in soils. Finally, how soil and soil composition, through the symbiotic relationship between the soil microfauna and plants, affects plant communities will be highlighted.

Our presenter is Gary Poole, an accomplished former Middle School math/science teacher, an electronics technician, bee keeper, and caver. Gary's graduate work in Geology left him with an abiding interest in rocks and their role in nature. Gary is a past president of our AAMN chapter.

With a 1.5 hour timeframe there will be plenty of time for questions related to rocks and soils and their effect on plant communities.

Please arrive to register for the event at least ten minutes before the 9:00 am start. Minors only when accompanied by an adult parent/guardian.
