What We Do At
Hallberg Butterfly Gardens
Every year, hundreds of Sonoma County schoolchildren visit Ms. Hallberg and her Gardens to learn about the life cycle of our
local butterflies. Children aren't the only people who come to the Gardens to learn, birdwatchers, lepidopterists, gardeners
and historians all have interests here. Many people in the local community enjoy participating as volunteers or
visitors, helping to spread the message of habitat preservation.
Open Gardens Day
Our annual Open Gardens Day draws hundreds of visitors from near and far. People come to
learn what they can do to protect and
enhance habitat for butterflies, to buy plants, and to enjoy a sense of Sonoma County's rich agricultural history. It is a
special community event, made possible by many volunteer hours, that brings together a wide variety of people with a passion
for natural history. Please visit our Open Gardens Day page to see highlights of recent years'
For the last ten years, Hallberg Butterfly Gardens has been dedicated to preserving and enhancing butterfly habitat developing,
through research and application, guidelines for habitat gardening that we follow and encourage others to adopt. Because natural
habitat everywhere is shrinking to smaller and smaller patches, we work to provide as much benefit to butterflies here at the
Gardens as we can.
Louise talks with Garden visitors
National Weather Service
Visitors can see the Graton U.S. Department of Commerce Weather Station with which Louise has been keeping records of the
weather for the National Weather Service since 1968. In addition to sending a monthly written report to the National Oceanic and Atmospheric
Bureau, she also reports to local Channel 50 (KFTY) by phone every afternoon, phones in her data to the Sonoma West Times and News
(local newspaper) every Monday, and sends a weekly written report to U.C. Cooperative Extension Service.
Natural HIstory Resource
The Hallberg Butterfly Gardens has become an important source of butterfly data in the past two decades,
as well as a repository for an extensive library of media clippings, photos, and books.
Ms. Hallberg has been keeping records of the Pipevine Swallowtail butterflies since 1986 and this close observation has
given her a unique insight to butterfly behaviors and population trends. Louise also records detailed accounts of bird
and plant life in the Gardens and with the recent habitat efforts, is providing a well-documented and directly observable
model for other gardeners, advocates, and preservationists.
