Dates of Earliest Sightings: 1976–2010
Greenbrook staff and members have been recording the
earliest spring dates for a number of events since 1976. The resulting 32 years
of data have been organized, calculating the earliest, average,
and latest dates for each event. The table below lists only a few of these
sightings. Why not visit Greenbrook to see the master table? Maybe you’ll be
lucky enough to add a few “firsts” for 2010.
This page is generally updated weekly; last updated on June 03, 2010.
