Two trees that have succumbed to Sudden Oak Death will be removed in the next month from the Los Trancos Open Space Preserve because they pose potential health hazards to hikers, according to the Midpeninsula Regional Open Space District.
Los Trancos Open Space Preserve is located off upper Page Mill Road above Palo Alto's Foothills Park.
"We have seen many more trees dying this summer," said Cindy Roessler, resource management specialist for the district. "We're concerned by how quickly the disease is moving into new areas and affecting different species of oaks."
Both trees are located at congregation points along a trail where docents lead trail hikes, Roessler said.
"We 're only removing trees that present a hazard to the public," Roessler said. "We're not taking out every dead tree."
The district has committed to spend $30,000 annually over the next 10 years for Sudden Oak Death research.
Sudden Oak Death is caused by a fungus-like pathogen that has killed more than a million tanoak trees in California and Oregon in the last decade, including hundreds on district preserves.
