The Delta Working Landscapes Program (Program) is a group of projects which demonstrate how farmers can integrate habitat restoration into farming practices. The objectives of the Program are to improve the environmental quality of existing landscapes in the Delta; coordinate programs with local farmers; understand the social, economic, environmental and governmental policy hurdles and/or incentives to perform conservation practices; and communicate to farmers the advantages of implementing wildlife friendly agricultural practices.
The Delta Protection Commission was awarded a three year grant to construct the program through the California Bay-Delta Program in 2005. Program partners included California Department of Fish and Wildlife Ecosystem Restoration Program, Hart Restoration (Hart) and Ducks Unlimited (DU). Hart established vegetative buffers along irrigation ditch banks and hedgerow grass plantings. These plantings were designed to provide habitat for wildlife, improve water quality by reducing runoff of pesticides and sediment, enhance levee stability, and retard levee erosion. DU coordinated restoration enhancement projects which included creating seasonal and permanent wetlands on marginal farmlands. These projects provide waterfowl brooding habitat, a food source, and additional habitat sites which promote healthier waterfowl flocks.
These projects total 312 acres of seasonal and permanent wetlands and 6.5 miles enhanced levees and waterways. Project areas established native plant life, have been repopulated by wildlife, and filter agricultural drainage which improves water quality and enhances levee stability. Multiple species of waterfowl are using the restoration habitat for brooding and feeding as well as staying later into the season. No easements, MOUs, fee purchases, or eminent domain were used.
Challenges to Working Landscapes projects include prior long term use of pesticides and herbicides which have created a hostile environment for native plants and wildlife. Additionally, some cultural practices are not conducive to habitat creation such as practices which rely on herbicides instead of tillage. Furthermore, economic costs are affiliated with physical land alterations, and in some cases permit requirements are cumbersome.
Despite these challenges, successful public/private partnerships are possible. Working Landscapes projects can be expanded through better communication between policy and regulatory agencies and publicizing successful projects.

Chronic problems of salt, selenium, boron and other naturally occurring elements in surface and groundwater supplies plague agricultural regions throughout the Westside of the San Joaquin Valley and the western U.S. Compounding the problem is the build-up of salty subsurface groundwater resulting from dense clay layers and inadequate natural drainage.
The Integrated On-Farm Drainage Management (IFDM) system was developed to manage these problems. A state-of-the-art, yet practical irrigation management system, the IFDM provides for drainage water reuse to improve water availability for crop production and to minimize salt and selenium risks to water quality and the environment.
IFDM manages irrigation water on salt sensitive, high value crops and reuses drainage water to irrigate salt-tolerant crops, trees and halophyte plants. Salt and selenium are removed from the farming system and can be marketed.
This system views the subsurface drainage water containing salts and selenium as resources, rather than considering them as wastes and environmental problems.

In 2008, Senate Bill SBX2 1 (Perata) was signed into law (Water Code Section 83002.5), requiring the State Water Resources Control Board (State Water Board), in consultation with other agencies, to prepare a Report to the Legislature to “improve understanding of the causes of [nitrate] groundwater contamination, identify potential remediation solutions and funding sources to recover costs expended by the State to clean up or treat groundwater, and ensure the provision of safe drinking water to all communities.”
The University of California prepared this Report under contract with the State Water Board as it prepares its Report to the Legislature. This executive summary focuses on major findings and promising actions. Details can be found in the Main Report and eight accompanying Technical Reports.

The goal of this guidance document is to provide the best, most relevant information to State agencies, regional boards, local agencies, and nonpoint source (NPS) practitioners to assist them in identifying and implementing practices to protect high-quality waters and restore impaired waters. This guidance document is not applicable to any facilities that are considered point sources under the Clean Water Act, including confined animal facilities that are Concentrated Animal Feeding Operations (CAFOs) as defined by USEPA.
The guidance is organized around the six NPS categories identified in the Plan for California's Nonpoint Source Pollution Control Program of 2000: agriculture, forestry, urban areas, marinas and recreational boating, hydromodification, and wetlands/riparian areas/vegetated treatment systems.
It supports the plan's goal of implementing the 61 NPS management measures by 2013. It also supports the implementation of NPS total maximum daily loads (TMDLs), as well as the development of TMDL implementation plans and watershed plans. A companion set of tools will also be available through the Internet to assist users in identifying potential management practices and estimating the effectiveness of those practices in managing pollution.
