Linking People and Ancient Landscapes
Dr. Alice Kelley
Instructor, Department of Earth Sciences; Assistant Research Professor, Climate Change Institute, University of Maine

Have Maine rivers been constant through time?

How did changing landscapes in the Penobscot Valley influence Native occupation and use of the region?

How can archaeology and geology be combined to better understand the geologic history and culture of our region?

Maine's Dynamic Landscapes:

From Deglaciation to the Future
Dr. George L. Jacobson
Maine State Climatologist, Professor Emeritus of Biology, Ecology, and Climate Change, University of Maine

How did the landscapes of Maine change during and after deglaciation?

How has Maine’s constantly changing climate influenced flora, fauna, and people?

How will future changes in climate affect Maine’s environment?

New England’s Forested Landscape:
History and Ecology

Tom Wessels
Ecologist; Founding Director: Master’s Degree program in Conservation Biology , Antioch University, New England

How have natural and human forces shaped New England’s forested landscapes?

How can we discern if a now forested area was once agricultural land or if it has always been forested?

How can we use forest stand types, shapes of trees, the pattern of decay in stumps, the construction of stone walls, and the lay of the land to interpret a forest’s history?

Soil Is Not Dirt

David Rocque

Maine State Soil Scientist, ME Department of Agriculture; Certified Soil Scientist, Licensed Site Evaluator, Licensed Professional Wetland Scientist.

What is the difference between a pile of dirt and a soil? How do soils form? How many different kinds of soil are there in Maine? Why do some soils have rocks in them while other soils don’t? How do the various soil layers form? What is a hydric (wetland soil) and how can you tell one from other soils? Join us for the answers to these and everything you wanted to know about soil but were afraid to ask.

Location: Hallowell City Auditorium & Jamies Pond WMA.

Co-sponsored by Hallowell Conservation Commission.

April 22 Earth Day, 4:30-7:30 pm

What Can We Learn From The Mud?

Andrea Nurse

Paleoecology Research Associate, Climate Change Institute, University of Maine; Adjunct Science Instructor, University of Maine, Farmington.

The sediments of wetlands and small ponds preserve a record of past changes in Maine's environment. Leaves, charcoal, seeds, pollen, and insects archived in successive layers of sediment show how the landscape changed since the last ice sheet retreated 14,000 years ago. We will explore the impact of changing climate on the landscape by examining wetland sediment cores.
