As a science-based organization, the Xerces Society produces dozens of publications annually, all of which employ the best available research to guide effective conservation efforts. Our publications range from guidelines for land managers, to brochures offering overviews of key concepts related to invertebrate conservation, from books about supporting pollinators in farmland, to region-specific plant lists. We hope that whatever you are seeking—whether it's guidance on making a home or community garden pollinator-friendly, advice on developing a local pesticide reduction strategy, or detailed information on restoring habitat—you will find it here!

Bees are difficult to identify to species or family without having pinned specimens. But bee richness at a site can be measured by identifying bees to groups based on their morphology (also known as morphogroups), which use characteristics that can be seen in the field to categorize bees.
Most butterflies are difficult to identify to species in flight or at a distance while walking a transect during a site monitoring. But butterfly richness at a site can be measured by identifying and monitoring butterflies to their families based on their morphology, using common characteristics that can be quickly recognized in the field.
This pocket guide lists common species in the Portland metro area, created in partnership between the Xerces Society and Portland Parks and Recreation.
Aproximadamente el 25% de todos los organismos conocidos del planeta son animales que viven en el suelo durante toda o parte de su vida. La mayoría de estos animales son invertebrados que interactúan con microbios, plantas y entre sí, dando forma a la vida de suelos saludables.
