For Immediate Release -
Scientists to Present New Findings on Presidio's Plants, Animals, and Archaeology
Presidio of San Francisco (May 4, 2007) -- The
Presidio Trust will host a symposium on Friday, May 11 bringing together
scientists who have recently studied the Presidio’s plants, animals,
insects and archaeology. This is an opportunity to hear about the
findings of a variety of studies at the Presidio and learn about
biodiversity in the park.
"We have always known that the Presidio
is a unique environment. These important studies reveal that it is also
home to great biological diversity and rich archaeological heritage”,
said Craig Middleton, Presidio Trust Executive Director.
than 400 species of animals can be seen at the Presidio. Many, like the
numerous bird species, make the park their seasonal home, while others
live here year-round. The park is permanent home to 21 raptor pairs,
made up of great horned owls and three different species of hawks. They
build nests and teach their young to fly in the Presidio’s forests.
of the nests produced at least one young,” said Allen Fish, Director of
the Golden Gate Raptor Observatory, “We watched many of the young take
their first flights in the park.” Mr. Fish led a project to inventory
the Presidio’s raptors in 2005 and will speak about his research on May
A San Francisco State study of bee diversity at the Presidio
revealed a booming community of 60 species. Bees are declining in most
of the Bay Area. “Despite its long history of habitat disturbance as an
Army base, the Presidio is still home to an impressive number of native
bees,” said John Hafernik, Professor of Biology at San Francisco State
University, who oversaw the bee diversity study. "This is important
because there is a worldwide concern about declining populations of bees
and other pollinators." Mr. Hafernik will give a presentation entitled:
Bees, Butterflies & Dragonflies of the Presidio.
Presidio also has a rich history that archaeologists have been working
to reveal. A presentation by Eric Blind, Presidio Trust archaeologist,
will focus on the discovery and study of the remnants of one of the
first buildings in San Francisco. Over the years, additions were made to
the original adobe, resulting in what is now the Presidio Officers’
Club building, “Our assessment is that the adobe walls within the
Officers’ Club remain solid despite being concealed for over 125 years,”
explained Blind. To examine the walls’ interior Blind used a fiber
optic scope inserted into a half-inch diameter hole drilled into the
adobe. He also laser scanned a room to create a 3-Dimensional model of
the building’s many layers.
The Presidio Science Symposium will
take place on Friday, May 11 from 9 am to 2 pm at the Golden Gate Club
at 135 Fisher Loop.
