We need to get creative to protect wildlife in the face of climate risk

The Swainson's hawk will need to be protected from the effects of climate change

A pilot project for Swainson’s hawk is creating high-quality nesting habitat on a 4,000-acre farm in San Joaquin County.

Landowners and environmentalists both grapple with the same question: In the midst of uncertainty, what is the most effective way to reconcile short-term and long-term needs for wildlife habitat?

For example, it can be risky to invest in permanent conservation on a property vulnerable to climate change, but failing to protect existing habitat in the face of uncertainty is an existential threat to species like the Swainson’s hawk.

Fortunately, new habitat accounting tools are emerging that bring more certainty to conservation planning, which helps landowners make effective management decisions for their property, helps biologists design effective restoration plans and ultimately helps wildlife thrive. Read More »

How can we better target public funds for wildlife conservation? Look to Elliott Ranch

The Swainson's hawk was listed as a threatened species in California in 1983 due to loss of habitat and decreased numbers across the state.

The Swainson’s hawk was listed as a threatened species in California in 1983 due to loss of habitat and decreased numbers across the state.

This week, the Delta Conservancy, a California state agency, awarded Environmental Defense Fund (EDF) a grant of $380,000 to implement a habitat enhancement project for the state-listed Swainson’s hawk on Elliott Ranch in West Sacramento, near the Sacramento-San Joaquin Delta. The grant is part of California’s public water bond funding being managed by the Delta Conservancy to restore wildlife habitat in the Central Valley.

The Elliott Ranch project will enhance Swainson’s hawk habitat on 300 acres. Specifically, the project will expand the hawks’ hunting grounds by restoring habitat for their prey and converting existing crops to bird-friendly pasture.

Central to the project will be the use of a habitat quantification tool (HQT) designed by EDF and local stakeholders to evaluate the current quality of habitat for Swainson’s hawk and compare restoration alternatives to optimize habitat outcomes. This will be the first time the HQT will be used as a mechanism to help allocate public funding to the most high value habitat improvements in California.

How California farmers can help salmon survive, and what’s in it for them

California's Chinook salmon are large fish that can grow up to 58 inches in length and weigh up to 129 pounds. But most salmon do not grow this large, especially in drought conditions where they lack sufficient habitat. (Credit: seafoodwatch.org)

Already an endangered species, California salmon populations have reached record lows.

Fisheries officials with the National Oceanic and Atmospheric Administration found that just 3 percent of this generation of winter-run Chinook salmon survived in the Sacramento River. This is a record low survival rate – more than 10 times worse than the survival rate before the California drought.

How does drought affect salmon?

Salmon at any stage need cold water to survive, and severe drought conditions have put a chokehold on the state’s water supply, which relies on snow melt from the Sierra Nevada Mountains. Without this snow melt, there is less cold water flowing into California’s waterways, creating higher than normal water temperatures in the Sacramento River.

But it’s not just the lack of cold water that’s affecting salmon populations. They also lack sufficient habitat to grow and thrive. Even if the drought ended today, they would still be in peril without adequate habitat. Read More »
