Looks like the National Phenology Network is chugging forward:

Over the past two years, Julio Betancourt of the Desert Laboratory has been collaborating with Mark Schwartz of the University of Wisconsin-Milwaukee and a group of scientists from various disciplines, federal agencies, academic institutions, and environmental networks to develop a wall-to-wall, coast-to-coast phenology observation network for the U.S. By January 2007, an Executive Director and National Coordinating Office will be located at the University of Arizona’s Office of Arid Lands, with funding from USGS and the University. Plans are underway for the first set of observations to be made nationwide in growing season of 2007.

This is a very neat project. A more detailed writeup from EOS last year.
