Greetings Creek Stewards,
Santa Rosa Creek is coming back to life! Most of the trees and shrubs that grow streamside are deciduous, losing their leaves for the winter. Along Santa Rosa Creek the first trees have broken bud and fresh, green leaves are starting to grow. Some of the first species to leaf out include willow, buckeye and alder. A general rule is the earlier a tree leafs out, the earlier it will lose it leaves in the late summer or early fall. Buckeyes already sport well developed leaves. These trees begin their dormancy, dropping leaves in August and even July! Compare that to the valley oak which may not be fully leafed out until later April. The valley oak will finally surrender the bulk of leaves to winter in November.
Other harbingers of spring currently present on the Greenway include mourning cloak butterflies. I watched several flitting gently along under the footbridge today. A large butterfly, up to 4 inches in wingspan, they overwinter as adults instead of moving south. Adults tuck away in sheltered places and are active early in the spring, aided by their black coloration that helps absorb warmth from the sun.
Like nature we are ready to break out of winter dormancy, enjoying being outdoors, appreciating fresh growth and the return of butterflies while warming up our muscles for summer fun. Please join us on Saturday, March 7th to witness the progression of spring and help further beautify the Prince Memorial Greenway for all.
Lets awaken, rise and help our creeks shine,
Alistair

Nature Quiz: Animals sometimes exhibit torpor over the winter. What does it mean? See answer below the picture of a mourning cloak butterfly.
 Torpor is a state of decreased physiological activity in an animal when body temperature drops and metabolism slows. Animals that undergo daily torpor when conditions are challenging include insects like this mourning cloak butterfly, birds and mammals, particularly rodent species and bats.
