To ensure healthy ecosystems, the Xerces Society’s endangered species team conserves at-risk species and their habitats through research, advocacy, education, conservation planning, and restoration. Our team of conservation biologists holds degrees in entomology, ecology, biology, and environmental science, and has decades of experience working with rare and at-risk terrestrial and aquatic invertebrates. We share a passion for conserving invertebrates that are imperiled with extinction.
The Xerces Society partners with the native seed industry to produce wildflower seed mixes meeting Xerces specifications, to provide foraging and nesting resources for a diversity of pollinators. For details about species composition, recommended seeding rate, and how to contact the producer, please download the specification sheet for each seed mix.
Monarchs are in decline across their range in North America. Loss of milkweed host plants due to extensive herbicide use has been identified as a major contributing factor, and loss or degradation of nectar-rich habitat from other causes, natural disease and predation, climate change, and widespread insecticide use are probably also contributing to declines.
