Located on California's rugged North Coast, roughly 250 miles north of the Golden Gate Bridge, Humboldt Bay is California's second largest natural estuary. Humboldt Bay's four major watersheds drain approximately 250 square miles. The Humboldt Bay watershed encompasses the ancient Headwaters Forest and privately-owned industrial timberlands, agricultural lands mostly used for raising dairy and beef cattle, salmon-bearing streams, huge expanses of tidal mudflats, and a variety of wetlands, including the only substantial area of salt marsh between San Francisco Bay and Coos Bay, Oregon.

Jennifer Kalt is a botanist with over 15 years of conservation advocacy work on the North Coast. She launched Humboldt Baykeeper’s Citizen Water Monitoring Program in 2005, became the Policy Director in 2011, and has been the Director since January 2014. She has become a local leader in environmental advocacy through watchdogging and grassroots organizing for environmental protections in local land use planning and coastal development projects with potential impacts to the Bay, its tributaries, and adjacent coastal waters. She holds a Bachelor’s degree in Botany and a Master’s in Biology, both from Humboldt State University.
