LEGISLATIVE COUNSEL’S DIGEST

AB 559, as amended, Lopez. Monarch butterflies: conservation.

Existing law establishes the Department of Fish and Wildlife and sets forth the duties of that department, which include administering various programs for the protection and conservation of fish and wildlife resources.

This bill would authorize the department to take actions to conserve monarch butterflies and the unique habitats they depend upon for successful migration. The bill would authorize the department to partner with federal agencies, nonprofit organizations, academic programs, private landowners, and other entities that undertake actions to conserve monarch butterflies and aid their successful migration, including the Monarch Joint Venture. The bill would require the department, when undertaking actions to conserve monarch butterflies and their habitats, to use the best available science and consider taking specified actions.

Vote: majority. Appropriation: no. Fiscal committee: yes. State-mandated local program: no.

The people of the State of California do enact as follows:

SECTION 1.  

The Legislature hereby finds and declares the
2following:

3(a) Monarch butterflies are a favorite butterfly of people
4throughout North America and concern for their survival brings
5people together like few other wildlife species such that, in
6February 2014, the United States, Mexico, and Canada joined
7efforts to ensure monarch butterfly recovery.

8(b) Monarch butterfly populations have declined significantly
9in the past 20 years to where the eastern population has lost 90
10percent of historical numbers and the western population has
11shrunk to 50 percent of historical numbers. California is the only
12state to host significant numbers of overwintering monarch
13butterflies.

14(c) While adult butterflies may obtain nectar from many different
15plants, monarch caterpillars can only survive when native milkweed
16plants are available for food. Of the 72 native milkweed species
17in the United States, several exist in California, including six that
18are endemic.

19(d) Milkweed habitat and density have declined significantly
20in the eastern United States, and it is suspected that they have also
21declined in the West. This has negatively impacted monarch
22butterflies as well as native bees, honey bees, and other beneficial
23insects, including insect predators of crop pests.

24(e) Since nearly one-third of the most promising California
25winter habitat for monarch butterflies is on privately owned land,
26collaboration with landowners is critical. Fortunately, many
27landowners are some of the strongest advocates for protecting and
28restoring overwintering and breeding habitat for the monarch
29butterfly.

30(f) Current environmental protection laws, including those
31concerning conservation and land use planning, have not
32adequately protected monarch butterflies, creating a need for
33additional collaborative restoration measures.

34(g) While several federal agencies, including the Natural
35Resource Conservation Service, the Farm Service Agency, the
36United States Forest Service, the United States Fish and Wildlife
37Service, and the Federal Highway Administration, are undertaking
38initiatives to protect and restore monarch butterflies, California
P3    1needs to take additional initiatives to guide and support monarch
2butterfly conservation.

3(h) Numerous public and private research entities and
4nongovernmental organizations are undertaking research and
5gathering information that could significantly contribute to
6California’s efforts to protect and conserve monarch butterflies.

1021.  

(a) The department may take actions to conserve
10monarch butterflies and the unique habitats they depend upon for
11successful migration. These actions may include, but are not limited
12to, habitat restoration on department lands, education programs,
13and voluntary agreements with private landowners.

14(b) The department may partner with federal agencies, nonprofit
15organizations, academic programs, private landowners, and other
16entities that undertake actions to conserve monarch butterflies and
17aid their successful migration, including the Monarch Joint
18Venture.

19(c) When undertaking actions to conserve monarch butterflies
20and their habitats pursuant to this section or other authority, the
21department shall use the best available science and consider, as
22appropriate, all of the following:

23(1) Restoring or revegetating monarch caterpillar habitat using
24regionally or locally appropriate native milkweed species.

25(2) Restoring or revegetating adult monarch butterfly habitat
26using regionally or locally appropriate native nectar plant species.

27(3) Controlling nonnative weed species that threaten native
28milkweed species using current best management practices
29consistent with integrated pest management principles that pose
30low risk to monarch butterflies and their habitat.
