At-Risk Invertebrates

We work on many of the most at-risk invertebrates-often they are small species that may be overlooked or not taken into account when management decisions are made. The Xerces Society works to raise the profile of these diverse and important animals-whether they be cryptic freshwater mussels, minute springsnails, or pollinating bumble bees.

In the Pacific Northwest, we are partnering with the Bureau of Land Management and US Forest Service’s Interagency Special Status and Sensitive Species Program to gather information and assess the status of many of their sensitive and potentially at-risk invertebrates. To date, Xerces’ staff have gathered extensive information on over 150 Pacific Northwest invertebrates, facilitating the prioritization of inventory, research, and monitoring for these animals. As a result of our record gathering and land ownership assessments, 29 species have become ‘sensitive’ species in Oregon and/or Washington, a designation that allows the species and its habitat needs to be considered in land management decisions.

Much of the information on individual species listed under the groups at the right has come from this work. In addition, we have conducted surveys to understand the distribution and conservation status of many species in Oregon and Washington, and recently Xerces staff completed a literature review summarizing the effects of logging, road building and burning on snails and slugs.
