The Lehigh Gap Nature Center, Slatington, will be celebrating its 10th anniversary May 12, 2013.

At the Sept. 29-30 Migration Fest at the center, a quilt made by members Donna Gasser and Kathie Romano was on display.

The quilt will be raffled off May 5, 2013, during a celebration and open house for the center.

Romano crafted all the birds, Gasser said.

During the fest, Diane Husic provided an update on the Eastern Pennsylvania Phenology Project. The cost was covered by an Audubon-Toyota TogetherGreen Fellowship.

The citizen-science project, with input from many people and organizations, tracks climate change through bloom times, birding and insects.

"We have people go out and look at things to learn about climate-change adaptation," Husic said. "If you get a lot of people out looking, you learn more.

"The science measures the life cycle of plants, animals and microbes and details how the environment influences the timing of these events."

She said the project is harder to do in the fall when living things are slowing down than in the spring when something that was not there over the winter returns.

One goal of the project is to get people outside watching and appreciating nature, Husic said. A second goal is to create a public database for regional phenology records.

The research can be followed at lgnc.org/ research/phenology. To submit data, email phenology@lgnc.org.

She has 13,000 pieces of data. Reports back to the 1960s add another 200,000 pieces.

Five counties were in the original plan but 18 are now included.

The Kittatinny Ridge is a dividing point with warming from south to north. The ridge also has the major contiguous forest in Pennsylvania.

The Louisiana water-thrush is returning 23 days earlier across the state. All birds are coming earlier, she said.

Nature Center Director Dan Kunkle said in the spring there is an urgency for raptors to get to breeding grounds but in fall they leave when they are running out of food.

There is no special urgency because the thermals are lasting later in the year.

Husic said it has been smart for municipalities to protect flood plains. With the predictions of climate change more water discharge will become common.

Other events were a identification of raptors program followed by a trip to Bake Oven Knob to watch hawks, a display of amphibians and reptiles and a craft table for kids.
