Holly Vaughn Joswick on Michigan Owls

Holly talked about the eight species of owls that breed in Michigan (Great Horned, Eastern Screech, Barred, Northern Saw-whet, Barn, Long-eared, Short-eared, and Great Gray Owls) and the three that winter in Michigan (Boreal, Snowy and Northern Owls). Her presentation included slides and bird calls.

Owl heads can rotate 270 degrees. They have huge eyes, equivalent to human eyes being the size of oranges. Owls have excellent hearing. They are able to detect a mouse moving under a foot of snow. Owls are primarily nocturnal. They have wings designed for silent flight, Owls also have great camouflage that made for the best photographs that the group enjoyed on March 8, 2018. Owls are raptors that eat small mammals, birds, insects, reptiles and smaller owls. Holly offered members sanitized pellets of undigestible material to investigate later.

Outside of habitat loss, predation and ingesting rodent poison, owls are generally doing well in Michigan. If you put up an owl box, the opening should face east and the box should be 15-20' high.

Spring Opener with Dean Krauskopf, PhD

At the well attended April meeting, members gathered to learn about important gardening issues from Dr. Dean Krauskopf. Dean began with a presentation then handled lots of questions from those present.

Dean talked about lead. Lead leaches under acidic conditions. If you ask about lead when doing a soil test, MSU will test for it. Lead paint was banned in 1978. There could be lead in the soil near a house built before then from lead paint. The lead, measured in parts per million (PPM), might dissipate quickly as you move further from the house. Lead is primarily taken up in the roots so do not grow root crops in contaminated soil. It is important to wash all garden produce well before consuming.

Dean pointed out that when a chemical, that is effective when used properly, is effectively eliminated as an option, the absence of a tool might create other problems. People may resort to using stronger or less effective chemicals that might be detrimental to pollinators or beneficial insects or might require multiple applications or more careful timing. One less option means one fewer tool to tackle a problem.

Dean talked about oak wilt, a problem we often perpetuate ourselves by pruning or cutting when beetles are out, which is anytime that the ground is not frozen. There is no cure or treatment except the destruction of infected trees. There is also no chemical control for Thousand Cankers Disease. Dean talked about IRAC, the Insecticide Resistance Action Committee, bees, heating degree days and accumulated chilling hours, that it's okay to prune roses now, how our 2015-2016 temperature swings are problematic for plants, micro environments, the benefits of raised beds, interrupting the life cycle of Viburnum leaf beetle, grass fertilization treatment programs, rubber tire compost, pre-emergent, dogs, peonies and rhubarb. It was a full night of science and sensible information.

Dean provided a variety of links to resources:
