In California, state and federal endangered species acts play an important and often outsized role in regulating water and land management. These powerful laws are also often at the center of conflicts between environmental and economic uses of water.

The state and federal acts have helped prevent the extinction of species and encourage better stewardship of water and the environment. But endangered species protection is often used as a proxy for protecting the environment, something the acts are not intended to do. Here’s why we need a better tool.

Opinion

Under the endangered species acts, state and federal agencies narrowly target regulations to protect listed species from direct harm and loss of critical habitat.

To illustrate, the recent dust-up between the Newsom and Trump administrations over proposed increases in water diversions from the Sacramento-San Joaquin Delta is mostly about actions affecting two endangered fish: Delta smelt and winter-run Chinook salmon.

This narrow focus ignores the fact that it is the ecosystems of the Delta watershed, and the diverse array of social, economic, and environmental benefits, that provide value to all Californians.

But given the narrow mandates of the acts, the arguments and lawsuits tend to focus on just one aspect of these ecosystems: the trade-offs between endangered species and water extraction.

Society places great value on native biodiversity and rightfully seeks to prevent extinctions. For many, protection of threatened or endangered species is a way to leverage improvements in the overall health of ecosystems.

Unfortunately, that is beyond the scope of the state and federal acts.

Recommending That California Adopt Ecosystem-Based Management

To promote healthy ecosystems and protect native biodiversity, California needs a different approach. We are not proposing major reforms to state or federal endangered species acts. Rather, we recommend a shift in the way these acts are implemented.

new report by the Public Policy Institute of California’s Water Policy Center recommends that California adopt ecosystem-based management.

Widely used in other countries and in marine fisheries and forest management in the United States, this approach emphasizes improving ecosystem condition. The goal is to simultaneously protect native biodiversity while improving other uses of freshwater ecosystems.

It integrates human needs such as water supply and quality, flood risk reduction, hydropower, recreation, and spiritual uses into management objectives and promotes actions that create multiple benefits.

Importantly, this approach is consistent with the acts and other state and federal laws that govern water management. A growing body of research suggests that managing at the ecosystem level, rather than emphasizing the protection of a narrow range of habitat deemed critical, improves the likelihood of recovery of listed species. It also helps head off future endangered species act listings by improving conditions for all native species.

Shifting away from single-species to ecosystem-based management will not be easy. It requires three things:

  • The state needs to rethink planning and governance processes to include all beneficiaries of freshwater ecosystems, not just advocates for water supply and endangered fish. This includes finding new ways to align agency priorities and permitting rules—now a major obstacle to ecosystem improvement projects.
  • The state needs to use new tools that go beyond traditional regulatory approaches for environmental water, such as setting minimum flow and water quality standards. One promising approach is to create ecosystem water budgets, which can be stored and traded like a priority water right. This water can be flexibly allocated to improve ecosystem condition, and managed along with habitat changes to maximize benefits.
  • The state needs to incentivize and institutionalize ecosystem-based management. Given its broad water quality and water right authorities, and its mandate to balance all uses of water, the State Water Board should take the lead.

Elements of Ecosystem-Based Management Are Being Employed Throughout the State

The board would set the criteria for ecosystem-based management plans and incorporate them into water quality control plans. Where possible, these plans would be supported by negotiated agreements between regulatory agencies, water users, and stakeholder communities.

Elements of ecosystem-based management are being employed throughout the state. For example, the Delta Stewardship Council and the Central Valley Flood Protection Board have plans to simultaneously improve ecosystem condition and human well-being.

We don’t need to start from scratch.

Elements of ecosystem-based management are being employed throughout the state. For example, the Delta Stewardship Council and the Central Valley Flood Protection Board have plans to simultaneously improve ecosystem condition and human well-being.

A novel ecosystem-based approach to water and species management is being implemented in the Upper Santa Ana Watershed in Southern California. And the Newsom administration’s efforts to develop voluntary agreements for environmental water allocation in the Central Valley take a broad approach to improve ecosystem health.

These nascent efforts are not enough. Changing course will require commitment to new ways of planning and managing. Most importantly, it will require risk-taking and leadership from the water users, state and federal officials and legislators.

This won’t be easy. But the alternative is to keep doing what we’ve been doing, which isn’t working for anyone.

    TRANSLATION: As witnessed with the change from “Global Warming” to “Climate Change”…when the facts don’t support the actions, change the mantra…and spread the “benefits” even wider.

    GOAL: Take more water from agriculture for failed policies under the guise of “better management”!

    “It integrates human needs such as water supply and quality, flood risk reduction, hydropower, recreation, and spiritual uses into management objectives and promotes actions that create multiple benefits.”

    “SPIRITUAL USES”? WTH?
