Options for Orphan Species

Off a bustling Delta highway, next door to a branch of the California Aqueduct, sprawls a tidy collection of shipping containers, humming pumps, and cylindrical tanks. Paved in cracked asphalt and encircled by chain link fencing, it resembles any number of light industrial sites at the margins of many communities. In fact, this resolutely artificial site is devoted to preserving a disappearing piece of natural California: the Delta smelt. “Our fish are a refuge population,” says Tien-Chieh Hung. Director of...

Wetland Protections in Transition

Environmentalists are heading warily into the fall following two regulatory developments that they fear may cramp efforts to protect California’s wetlands. In June the State Water Resources Control Board released a draft document overhauling wetlands protection procedures but leaving open the question of exactly which wetlands are eligible for protection. In the same month the U.S. Supreme Court ruled that landowners may mount court challenges to U.S. EPA or Corps of Engineers jurisdictional determinations before a permit is issued, potentially...

Mainstreaming Resilience

Whatever the “perturbation” coming our way – a flood, a drought, a weed or Donald Trump – our recovery, in the aftermath, depends on something ecologists call resilience. It’s a term everyone is pasting onto their management initiatives these days – resilient landscapes, resilient shorelines, resilient water supplies, neighborhoods, infrastructure… But what exactly does it mean, and how is it different from other fashionable buzzwords that have galvanized Californians into thinking about the future?

Scaled-Down Plans to “Fix and Restore”

Surprising many observers, Governor Jerry Brown announced late in April that the Bay Delta Conservation Program, which had embraced the new water conveyance popularly known as the Twin Tunnels and a broad program for restoring the complex and heavily impacted Delta environment, was being split into two new entities: Cal WaterFix and Cal EcoRestore. This was followed
by the release of a Partially Recirculated Draft Environmental Impact Report/Supplemental Draft Environmental Impact Statement spelling out the changes: on the conveyance side, reduction...

Cullinan Finally in the Fold

Real estate developers often name their projects for what they’ve displaced: Quail Acres, Live Oak Estates. Egret Bay would have been another such necronym. The 4,500-home development proposed for the former Cullinan Ranch on San Pablo Bay in 1983 would have left little room for egrets, or other birds. A citizen’s group, Vallejoans for Cost Efficient Growth, supported by Save the Bay and other environmental organizations, helped kill Egret Bay, and, in a deal brokered by Congresswoman Barbara Boxer, the...

Offers They Can Refuse

The numbers are daunting: 8,000 acres to be restored to fish-friendly tidal habitat in order to comply with federal wildlife agencies’ Biological Opinions; another 65,000 if and when the Bay-Delta Conservation Plan is implemented; more still if you add in mitigation for levee operations. Where will that acreage come from? State agencies and other public entities already own some parcels suitable for restoration, but not nearly enough: the rest will need to be purchased from its current owners or covered...

Defter Delta Restoration

An issue paper endorsed by the Delta Stewardship Council this August seeks to spark progress throughout the myriad stages of habitat restoration. As public and private interests gear up to help endangered fish and migrating birds by restoring habitats in six priority zones of the Delta and Suisun Marsh, this paper lays out tools and concepts for getting the most out of these investments and learning from our mistakes. The paper details steps for achieving effective restoration, reviews barriers such...

Hamilton Done, But More To Do

Breaching the outboard levee near Marin County’s Hamilton community this May is cause for both a whoop of celebration and a sigh of relief. Celebration because it was an ambitious wetland restoration project with a complicated design and multiple partners that wasn’t easy to pull off, yet in just a few months it’s become a beautiful landscape filled with blue water, green shoots, yellow flowers, quacking ducks, and happy neighbors. Relief because at times the costs and challenges of moving...

Freeing Fish While Locking Up Mercury

The restoration of the South Bay salt ponds to tidal wetland has, from the very beginning, been an exercise in adaptive management: take an action; monitor the results; make any indicated fixes; repeat. There’s no better example than Pond A8, where the Guadalupe River enters San Francisco Bay via Alviso Slough. Restoration planners were worried that connecting the former salt evaporation pond with the Bay could introduce long-dormant mercury to the wider ecosystem, and initial studies of levels in water...

The Island That Came in from the Cold

For years, Skaggs Island was a tantalizing blank in the map of San Pablo Bay wetlands restoration. Renee Spenst of Ducks Unlimited says it was “one of those places in a strange limbo.” Two-thirds of it was owned by the US Navy, which had operated a top-secret listening post there; the rest was privately-owned farmland, where the Haire family grew oat hay. Converting any of the 4,400 acres back to tidal wetland was out of the question. “The agencies doing...
