Some results from out Earth Week "World Series of Phenology" in Eastern PA

One sign of spring is that those of us in academe are really busy at work when nature brings on her spring show!  Now that commencement is over, I will try to catch up on the blog posts from the past several weeks!  Thanks to Meredith who helped to compile the information that was sent in and many thanks to everyone who submitted data during Earth Week, your efforts are greatly appreciated!  dwh

Pre-Earth Week

Carissa reported that the following plants were seen in bloom at the Varden Conservation Area in Wayne County on April 14th, shortly before Earth Week began:

·        Dutchman’s Breeches

·        Trout Lily

·        Red Trillium

·        Sessile-leaved Bellwort

Additionally, Spring Beauty was also seen on the 14th in Promise Land State Park in Pike County.

New growth on the Mountain Laurel at Big Pocono - April 14th
Pap reported in from Tuscarora:

"On the Spirit Trail this evening I found new growths of both Lady’s Thumb Smartweed and Pennsylvania Smartweed. Also Common Buttercups have come up as well as Yarrow. The Multiflora Rose is leafing out. This along with Barberry and Autumn Olive are the three main invasives we have there. There are some patches of Mile A Minute Plant and Japanese Knotweed but the park is doing a good job on removing and controlling them. Stopped by one of the Wood Frog pools. The pools were devoid of frogs and I didn’t see any more egg masses. This is a small amount compared to what I’ve seen in previous years. That spell of cool weather we’ve had recently has certainly effected their reproduction this year. The Osprey is still feeding at the lake."

Kathie from Plainfield Township near Wind Gap noted that the marsh marigolds, dandelions and trout lilies were blooming for the first time.

From Upper Saucon, Carolyn sent pictures of bloodroot:
