In California, a day’s drive can take a visitor from record-setting desert heat to glaciated peaks to temperate rainforests with the world’s tallest trees. This astounding climatic and landscape diversity has helped create a biodiversity hotspot. California is also an economic hotspot – the 6th largest economy in the world – and is home to nearly 40 million people. The demand for land for new development and farms, along with accelerating climate change, puts tremendous stress on ecosystems, and the benefits they provide.
The state’s legacy of conservation has created a network of natural and working lands that benefit people by supplying clean water, capturing carbon, and directly contributing to the state’s economic and cultural vitality through recreation, tourism, and agricultural production. Conservancy scientists work across the spectrum of ecosystem types and human land uses, to advance conservation goals that also contribute to the well-being of people in those places.
