Presidio restoration underway

About 100 volunteers are planting more than 50 plant species in the Presidio of San Francisco Saturday, part of a long effort to restore the former U.S. Army base to its natural state.

The restoration is starting in El Polin Springs in the Tennessee Hollow in a small area where the Presidio Trust has already gotten rid of multiple eucalyptus trees. The trees were a nonnative species that made it too difficult to restore the area, a trust employee said.

"We're restoring it back to the community it used to be," Presidio Trust employee Andrew Kleinhesselink said.

The watershed only had about five species before the Presidio Trust started restoring the area and about half of them were nonnative, Kleinhesselink said.

After Saturday, the native species will be back in action. "We're going to get a few thousand plants in the ground," he said. "By springtime it will be much greener."
