Who Is
Hiding in Vernal Pools?
A vernal pool
outing in Walden Woods
On June 10th,
2006 the Walden Woods Project led a Vernal Pool
outing in Walden Woods. Despite the rain, 18 people
showed up for the event, led by vernal pool experts Leo
Kenney, Mark Maguire, and Matt Burne (the Land
Conservation Coordinator at the Walden Woods Project).
The group first visited a vernal pool close to
Thoreau’s cabin site. All three leaders got into the
water and started collecting vernal pool creatures
using their nets. The majority of the catch
consisted of salamander larvae, frog tadpoles,
beetles, among a few other organisms. Participants
were able to inspect the creatures that were caught
close-up, while the leaders provided identifications
and discussed the natural history of the habitat, landscape, and
organisms.
The group then went to the Wyman Meadow, a very
different type of vernal pool. Due to the
heavy rains, the pool was almost
connected to Walden Pond,
which, though not unheard of, happens only
occasionally. A red-spotted newt, American toad and
green frog tadpoles, and many dragonfly and
damselfly larvae were found. The natural history
interpretation for these pools included a comparison
between vernal pools and lakes such as Walden Pond.
The program was thoroughly enjoyed by both adults
and kids in attendance.
The event
was part of the Walden Woods Project's
Discovering Walden Woods series and of
the annual SuAsCo Watershed's
RiverFest event.
Am
surprised to hear, from the pool behind Lee’s Cliff,
the croaking of the wood frog… How suddenly they
awake! yesterday, as it were, asleep and dormant,
to-day as lively as ever they are.
The awakening of
the leafy woodland pools.
