Invertebrates form the foundation of many of our terrestrial and aquatic ecosystems, and yet they are greatly underappreciated in mainstream conservation. Destruction of habitat, pesticides, disease, and climate change are all factors leading to the decline of invertebrate species. To conserve and restore the diversity of life on earth, the Xerces Society’s endangered species conservation program engages in education, research, community science (sometimes referred to as "citizen science," or "participatory science"), conservation planning, and advocacy to protect at-risk species and their habitats. We collaborate with scientists and land managers to raise awareness about the plight of invertebrates and to gain protection for the most vulnerable species before they decline to a level at which recovery is impossible.

The western monarch migration is having a better year, but this isn’t population recovery.

Fire has been used to manage prairies for centuries, and remains an important tool for grassland managers to reduce woody plant encroachment and increase flower production of key nectar and pollen sources. However, burning entire landscapes is problematic for pollinators, and fire must be used carefully.

In Santa Fe, NM, Xerces is working with local partners to develop a city-wide Pollinator Trail focused on creating connected habitat through neighborhoods that lack greenspaces. In September, after months of planning and preparation, 350 habitat kits were distributed to residents and organizations. When many people come together around a common goal, small efforts can quickly add up to large-scale conservation.
