Meet Forest Committee members at the next Forest Committee meeting, Wednesday, January 10, 6:30 pm at Rabobank. Forestry professor Sarah Bisbing will speak on the effects of drought and disease on demographic processes in endemic Monterey pine.
Cambria’s rare Monterey Pine forest is changing as it is exposed to increasingly frequent droughts that stress trees. The forest is not dying, but responding to the stress of extreme climate conditions.
“The recent drought generally took out the weakest and oldest individuals,” said Sarah Bisbing, Ph.D, assistant professor of forestry at University of Nevada Reno, “but I’m not concerned about wholesale loss of Monterey Pine. We are continuing to see regeneration and growth in residual trees.”
Bisbing will present her findings at the Cambria Forest Committee meeting Wednesday, January 10, 6:30 pm at Rabobank. Her subject is: Drought and disease shape demographic processes in endemic Monterey pine. The talk is free. The Committee’s Invasive Weed Guide will be available for sale, $8. Donations are always welcome. The Forest Committee is a 501c(3) nonprofit organization.
Bisbing is a forest ecologist who has made the forest the focus of her work. She studied data collected between 2001 and 2016 to determine what influenced which trees survived and which ones died.
Bisbing used a measure of climatic stress to evaluate how local climate and environmental factors drive tree response to changing conditions. This metric provides a surrogate for tree stress and is calculated using the local variables, such as total moisture, extreme temperatures, aspect and soil depth. She additionally tracked the influence of non-native pine pitch canker on the forest over time, and discovered that many did not die from infection. Mature trees tolerated infection, while some saplings died.
“Conifers can handle a few years of extreme stress,” she said. “They have evolved to grow in more stressful environments deciduous trees can’t tolerate.”
Over time the forest has continually changed. Historically, Monterey Pine occupied much of coastal California. It expands and contracts in response to climate conditions. Following the last El Nino, for example, many seedlings got started, but few persisted. Seedlings crowd each other out, competing for resources. Only those in the right place and with the greatest access to resources survive.
Monterey Pine has a limited range on the California coast, although it’s the most widely planted conifer globally.
“The number one threat to the Monterey Pine forest is human development and urbanization,” she said. “This species has nowhere to go.”

Weeds are taking over landscape and crowding out native plants. Weeds hurt the forest by changing the habitat for wildlife. they increase fire danger. Pull weeds on your own property and help your neighbors. Every weed you pull reduces the number of seeds that will sprout on your property next year. Connie Gannon, executive director of Greenspace–The Cambria Land Trust and a member of the Forest Committee’s board, wrote about it in The Cambrian.

In 1985, The Land Conservancy was selected as the implementing nonprofit agency as required for government agencies to operate the Transfer Development Credit Ordinance. Following the completion of the Cambria-Lodge-Hill Restoration Plan, the TDC program received seed money from the state Coastal Conservancy to begin retiring lots. Lots retired from development are permanently restricted to open space and their development rights can be transferred to areas in Cambria where development is better suited and which will have a reduced impact on the health of the native Monterey pine forest. The County directs landowners who wish to exceed present county development standards to The Land Conservancy to purchase TDCs. That money is then used to purchase additional undeveloped lots and retire them from development, and the cycle continues.
In March 2016, after a four year hiatus, the Cambria CSD accepted 52 lots from the Land Conservancy. That allows the program to continue. Read the news report here.
The CSD established a Buildout Reduction Committee to move the program forward. Follow the committee’s progress at the tab above.
Grant to remove dead trees
Cambria has been awarded a $498,736 grant to reduce the fire fuel hazard of dead trees. Read the Cambrian’s coverage here. Greenspace executive director Connie Gannon writes about how this can involve the Forest Committee here.
The Organizational and Funding Options for Implementation for the Cambria Monterey Pine Forest Management Plan is now posted on the Forest-Related Documents page. The Forest Management Plan is also posted there.
