Kennebec Land Trust has announced the dates and speakers for its 14th annual March Lyceum lecture series. Maine Streams and Rivers and their Ecology is this year’s program, according to a news release from the trust.

The following free programs will be held at the Ladd Recreation Center in Wayne:

• Maine’s Streams and Rivers: The Interplay Between Water, Rocks and Biology, 7-8:30 p.m. Thursday, March 17. Hamish Greig, assistant professor of Stream Ecology, School of Biology and Ecology, University of Maine, will focus on the hydrology of streams and rivers; how water shapes river habitat; and stream and river ecosystems and their food webs.

• Maine’s Stream Fish Populations, 7-8:30 p.m. Thursday, March 24. Merry Gallagher, research fishery biologist, Maine Department of Inland Fisheries and Wildlife, will focus on stream fish ecology, native stream conservation, and fish community patterns across Maine.

• Rare and Uncommon Stream Species and Communities: Their Role in Conservation and Restoration, 7-8:30 p.m. Thursday, March 31. Joshua Royte, conservation scientist at The Nature Conservancy, will provide an overview of rare and uncommon stream species and communities and will explain how rarity influences conservation and restoration work.

2016 Spring and Fall KLT Lyceum Field Programs:

• The Birds and the Bugs: Life along a Maine Stream with Tom Danielson, Maine Department of Environmental Protection; and Dave Courtemanch, The Nature Conservancy, 8-10 a.m. Saturday, May 14, Reynolds Forest, Sidney. Streams provide an important microhabitat on the landscape. Despite their small size, streams support a surprising diversity of aquatic life which in turn supports a unique ecosystem within the forests. A trip along Goff Brook will look at life in and around the water. Bring binoculars and boots.

• Culverts: The Good, the Bad, and the Ugly with Jeremy Bell, The Nature Conservancy, 4-6 p.m. Thursday, Sept. 22, Location to be announced. Field Workshop for Municipal Officials, Planning Boards Conservation Commissions. Many of us drive over culverts daily without giving them a second thought. Meanwhile, they are major conduits for the rivers, streams and fish. Participants will look at a variety of culverts in central Maine: some good, others bad and ugly. The focus of the trip will be on looking at culverts from a fish passage and flood preparedness perspective. Bell, a stream restoration specialist at The Nature Conservancy, will explain what makes a good road crossing that will keep roads and streams functioning in all weather conditions.
