California Monarch and Pollinator Habitat Kits

Kits are intended to be used to create or enhance monarch and pollinator habitat on working lands, public lands, tribal lands and private/non-working lands recovering from wildfires, with landowner or land manager collaboration. This includes farms, ranches, tribal land, post-wildfire recovery areas, urban farms or gardens, city parks, school gardens or other public areas. 

The kits are not intended to be used in home gardens.  

We encourage stewards of working lands to partner with organizations or entities that can provide additional technical support for their projects, such as Resource Conservation Districts (RCDs), The Natural Resources Conservation Service (NRCS) or other conservation organizations.

If you have questions about your project’s suitability or requests for technical guidance on your project, please email us at centralvalleypollinators@xerces.org.

We have kits available for Sacramento Valley, San Joaquin Valley, Sierra Nevada Foothills, Central Coast and Coastal Foothills, and Southern California regions. Please enter your address in the map below to determine which kits are available for your location. 

If you do not see your region listed, we do not have kits suitable for your region.

We have several types of habitat kits available and the contents of each kit type varies by region. Some kit types are only available in certain regions because we want to work with local plant and seed producers and use local plant ecotypes in our habitat kits as much as possible.

All kits are comprised of native plants that have been identified as having high value to monarchs and other pollinators and are grown without the use of systemic pesticides that may be harmful to pollinators. You may request multiple kits if needed for your project.

Monarch Overwintering Kits

We are now offering monarch overwintering kits, intended to be used in or near monarch overwintering sites along the coastline (see interactive map), and in other coastal areas outside of the range of milkweed. These kits contain 36 perennials, grasses, and shrubs.  These kits will not contain milkweed and will focus on species that provide nectar year-round, especially in the winter. Each kit will cover approximately 576 ft2 when planted on 4 ft spacing. Container sizes range from tree band to 1 gal. Minimum order of 1 kit/ project. Additional kits can be requested for larger projects.

Proposals 

We are accepting proposals for 2025 from February 10 through April 4. Project proposal forms are available in English and Spanish.

The Project Proposal Form collects information about where the kit will be planted, the size of the area, and plans for site preparation, management, and maintenance, as well as plans for pesticide risk mitigation and outreach opportunities, if applicable. A limited number of habitat kits are available and we receive more requests than we are able to fulfill. Participants are selected based on the project information set out in proposals as well as considerations such as location and habitat implementation and management plans.

Single kits are not designed to be divided into multiple projects, and we are not able to provide partial kits or to customize kits for specific projects. Participants must be able to use the entire kit/ minimum order in one project but it can be divided up within the area. For example, several plantings within one county park, or several areas on a farm or ranch. If applying for kits for multiple projects, please fill out a separate application for each project.

Distribution 

Kits will be available for pick up in late October or in December (Southern CA). You will be provided with habitat kit pick-up days and locations if/when your proposal is awarded a kit(s). There will be a range of dates (usually around 4 days) and times when the kits will be available for pick-up.

• Kits for the Sacramento Valley, the San Joaquin Valley, and the Sierra Nevada Foothills will be available for pick-up at the USDA Plant Materials Center in Lockeford, CA
• Kits for the Central Coast and coastal foothills kits will be available for pick-up at Our City Forest in San Jose, CA.
• Kits for Southern California will be available to pick up at the Native West Nursery in San Diego, CA, or the GrowGood Urban Farm in Bell, CA.

Planting, Maintenance, Reporting

You are required to plant the kit within a reasonable amount of time after receiving the kit (1–2 months), and to follow the plan outlined in your proposal. Once the kit is planted, you must contact us to let us know the kit is planted, and share some photos. A brief report (~1–2 pages) is due the following June which should include information such as the amount of area planted and the establishment success of the project. You will also be asked to submit a photo of your habitat once per year for up to 5 years. If awarded a kit, you will receive a project partner collaborative agreement that outlines all requirements.

Who should I contact if I have questions?

You can contact us at centralvalleypollinators@xerces.org with any questions about our California habitat kit program.

How do I participate in the Habitat Kit Program?

Project proposals for California Monarch and Pollinator Habitat Kits will be available each year in early spring. The form asks for information about where the kit will be planted, size of the area, and plans for site preparation, management, and maintenance, as well as plans for pesticide risk mitigation and outreach opportunities, if applicable. We have a webinar with tips on filling out the project proposal form.

Can I have the kit delivered to me?

Kit delivery is not available. You must pick up your kit from one of our kit distribution locations (Lockeford, San Jose, or Temecula, CA).

How did you decide what plants to include in the kits?

The plant species included in the kits have been chosen based on monarch nectaring observations compiled from numerous sources, including published and technical reports, research datasets, and personal communications with monarch researchers, botanists, and other experts. Visitation data provides good general guidance on which plants are preferred by monarchs. Additional factors, such as availability, climate adaptiveness, regional and site suitability and general pollinator attractiveness, were also taken into consideration. We also include important host and nectar plants for other declining pollinators whenever possible. All plant species in the habitat kits are native to California.

Why are the kits available in the late fall/winter?

Fall through early winter is actually the best time to plant California native plants!  The winter rains help the plants to establish and the cooler temperatures reduce stress on newly planted seedlings.  The plants are ordered in advance from our partner nurseries so that they are well-rooted and ready to plant once you pick them up. Delaying planting can reduce the chances of your plant successfully establishing. 
 

I would like to create a pollinator garden at a school (or other public place). Which kit type should I choose?

The Garden Kits are most appropriate for creating a small pollinator garden because they are smaller kits and have a diversity of plants. The wildflower grassland kits are too large for a small pollinator garden and the hedgerow kits have many shrubs, which make them inappropriate for most pollinator gardens.

I am receiving additional funds for my project through an NRCS Farm Bill Program and / or a CDFA grant. Can I still apply for a kit?

Yes, you can leverage other funding sources and apply for a kit. However, you must check in with your NRCS or CDFA contact to make sure you are still fulfilling your contractual obligations.

Are habitat kits organic?

Habitat kits are not certified organic, but are grown without the use of harmful pesticides. 

Can I purchase a kit on my own?

The kits are not available for sale.

Can I get technical assistance for creating and maintaining my kit?

Yes! We are happy to help. You may contact us at centralvalleypollinators@xerces.org with questions about your project and for advice on how to ensure that your project will be successful.

We have created a planting guide for our California habitat kits. You can also find a variety of information and materials on our website, particularly in the Pollinator Conservation Resource Center.

If you are interested in planting a kit on working lands, you may also want to seek assistance from your local Resource Conservation District or the NRCS.

I do not live in California. Am I eligible for a kit?

While this particular habitat kit program is only for Californians, we do have habitat kit programs in other regions.

How can I support the Xerces habitat kit program?

The habitat kits are possible thanks to the generosity of Xerces Society donors and members.
