Lake Herman Open Space Project

In 2014, the Benicia Tree Foundation looked for a easier way to plant trees more quickly and with lower cost.  Rather than buy nursery grown trees in five-gallon or 15-gallon pots, we collected acorns along Lopes Road and sprouted them in tree pots that winter.  While these acrons grew, we asked the City of Benicia if we would plant the tree saplings in the City's open space property between Community Park and Lake Herman.  The City agreed to let us plant the sapling in the open space east of the pedestrian trail linking Community Park to Lake Herman Regional Park.  Since the open space is grazed by goats and gophers, we would need to use gopher cages and chicken wire to protect the saplings for two or three years after planting.

In November 2015, we hired the California Conservation Corps crews, one from the Delta and one from Napa, to plant 100 oak saplings in the Lake Herman Open Space.  We weren't sure how many they could plant.  They started at 9 and planted 50 by noon.  After lunch, each crew member volunteer three hours of their time to plant the remaining 50 saplings, each with a gopher basket and chicken wire cage.  We were done by 4.

We wanted to water the trees for the first two dry seasons in order to improve the survival rate of the tree saplings.  We purchased a water tank that fits in the back up a pickup.  We drive the pickup with the water tank to the trees and use plastic gallon-size containers to give each tree two gallons of water.  The first dry season was 2016, during the drought, so we used a cornstarch-base water supplement called Dri-Water, which allowed us to water a two-month intervals from May to October.  Volunteer crews from Valero are helping us weed around the saplings and water them.  After the first dry season, we are seeing an 80% survival rate for the saplings.
