Oak Knoll Mixed-Use Community Development

Long-term vegetation management including fuel reduction and invasive plant removal for oak woodland preserve as part of a mixed-use redevelopment site

This project is part of WRA’s work to support the redevelopment of the 183-acre former Oak Knoll Naval Hospital located in Oakland, California which began in 2016. WRA Landscape Restoration (WRA-LR) leads fuel reduction and invasive plant removal efforts at the site, which includes the restoration of a 2.5-acre oak woodland preserve that abuts Rifle Range Creek. In the first year of vegetation management, the WRA-LR crew removed a dense understory of mixed-aged French Broom that was growing up to 12 feet high, which posed a serious fire risk to this grove of old-growth Coast Live Oaks as a ladder fuel. Manual methods including hand pulling and weed wrenches were used to remove the broom stand and mitigate this risk to the environment and community.

The WRA-LR team will return to the site for 10 years to continue managing these fuel sources and eliminate the broom seed bank, allowing the native understory to reestablish.
