The
Lucy T. Hammer Woodlands: A Gem
By Vincent A. De Luca, Jr. and Bill Horne, 2006
The Lucy T. Hammer Woodland is a 26.5 acre preserve with a remarkably
varied landscape of woods, meadow and ponds that lies not far from
the center of Branford. It provides a fascinating portrait of some
of Branford's exciting geologic history and the multiple land uses
typical of the history of early New England forest. With its varied
terrain and habitat, including remarkable spring wildflowers, this
is a gem among the more than 90 tracts of land that the Land Trust
owns and manages.
The Hammer Woodland's history starts about 230 million years ago when
the North American, European and African plates that formed the supercontinent
Pangaea began to separate. In the process, many cracks (faults) developed
along the boundary between the North American and African plates.
One of them, the Triassic Border Fault, extends from Long Island Sound
at Light House Point northward to the Massachusetts-Vermont border.
As the fault widened and the rock on the west side of the fault sank
below the level of the east side, the resulting valley filled with
alternating layers of eroded sediment and volcanic lava, which eventually
formed the arkose sandstone and traprock (basalt) ridges of Connecticut's
central valley.
In Branford, the Triassic Fault passes along the eastern edge of the
Hammer property. Both sandstone and traprock bedrock are found on
the Hammer property, but the traprock is the most prominent. It forms
Todd's Hill, the highest feature of the Hammer property and the easternmost
of a series of traprock ridges that include Beacon Hill and Saltonstall
Ridge, East Rock and West Rock. The other prominent geological feature
of the Hammer Woods is a drumlin, a hill formed by sediment (till)
left behind when the last glacier melted 10 thousand years ago that
is now Cherry Hill. The soils of the Hammer Woodland were formed from
the glacial till and the weathering of the basalt and sandstone.
The historic land use of the Hammer Woodland typifies what occurred
in much of New England. Before European colonization, Quinnipiac Indians
lived and hunted here. In 1674, three decades after the settlement
of Branford, what is now the Hammer Woodland and other property was
deeded to Isaac Bradley. For the next two centuries, the Bradley family
cleared the forest for grazing and agriculture, using the trees for
building and fire wood. Like most of New England in the first half
of the 19th Century, the Hammer Woodland would have been largely cleared
of trees. Natural reforestation began in the mid-1800s as people stopped
working farms and took up industrial work or migrated to more fertile
areas in the Mid-West. For that reason, few trees in the northeast
are more than 150 years old.
In addition to farming, the Bradleys created three ponds by damming
a small stream that ran through the valley between Todd's Hill and
Cherry Hill. These ponds, and later the Branford Supply Pond, supplied
a flourishing ice business that provided ice to residents until electrical
refrigeration became widely available in the first decades of the
20th Century. An ice house foundation can be seen not far from Gurd's
Pond, named for Gurdon Bradley, the namesake grandson of the builder
of the dam. The original dam was dismantled in 1940 but rebuilt by
Thorvald and Lucy Hammer after they purchased the property in 1948.
The forestation of the property increased after the Hammers acquired
the property, primarily by natural processes and partly by the planting
of Douglass fir, white pine and other conifers. The dark traprock
on Todd's Hill absorbs heat and forms a warm microclimate that encourages
the growth of early spring wildflowers, particularly on the east side
of the hill. The ponds are excellent seasonal sites for migrating
water fowl, for marsh nesting birds and for turtles, amphibians, pond
fish and for observing natural aquatic succession. The Land Trust's
involvement with the Hammer Forest started in June 1984 when Thorvald
and Lucy donated 23.8 acres of woods and ponds. Eight years later,
Lucy donated "The Lea", the meadow between the original donation and
Cherry Hill Road, creating the current preserve. Since receiving the
land, the Land Trust's stewardship activities have focused on maintaining
the trails for recreational use and mowing the Lea to keep it from
reverting to woodland as the rest of the property has. But it has
not been all work. Peter Borgemeister, a long time member of the Branford
Land Trust, remembers the Land Trust throwing skating parties on the
largest pond. Lucy Hammer used to join them for hot chocolate and
doughnuts. Truly, a Currier and Ives setting.
We are now conducting an inventory of the vegetation on the property.
A report will be prepared that compares our findings to those in a
1985 study performed by students from the Yale School of Forestry
and Environmental Studies, and will describe how the vegetation of
the property has changed in the last twenty years. (Much of the information
in this article was obtained from the Yale report, which is available
for those interested in more details.) The map shows the location
and layout of the preserve and the management units and plots used
in the current survey.
We hope that this brief picture of the Hammer Woodland will entice
our readers to explore and enjoy this beautiful preserve. The entrance
to the Hammer Woodland is on Cherry Hill Rd., about 0.1 mile north
of the intersection of Cherry Hill Rd. and North Main St., across
the street from the Montoya condominiums. |
