California State Parks operates nine State Vehicular Recreation Areas (SVRAs) across California, where recreational vehicle enthusiasts can explore the landscape in a regulated environment. Managers of these parks are tasked with providing opportunities for off-highway vehicle recreation, while monitoring and minimizing negative impacts to plant and animal populations. In recognition that bird populations can serve as particularly good indicators of ecological disturbance, IBP is partnering with California State Parks and the National Audubon Society to monitor bird populations in the parks. We are integrating traditional survey methods with the latest technology in automated recording units – programmable devices that collect sound recordings that are later analyzed by experts at acoustic bird identification and/or software that can transcribe the recordings automatically.
