The Bone Cave harvestman, a blind, cave-dwelling spider found in Travis and Williamson Counties, Texas has been at the center of a heated debate since its listing in 1988.
On June 2, 2014, The U.S. Fish and Wildlife Service (Service) was petitioned to delist the species. An original 90-day finding was published on June 1, 2015 that the petition did not present substantial scientific or commercial information indicating that the petitioned action was warranted. On December 15, 2015, the petitioners challenged the decision in Federal District Court. Subsequent information was submitted in October 2016 by the petitioners and the petition was re-evaluated.
On May 4, 2017, the Service announced its second 90-day finding that the petition still does not present substantial scientific or commercial information indicating the delisting may be warranted.
This decision ends the Service’s formal consideration of the petition, but the Service is currently conducting a five-year review of the Bone Cave harvestman as required by section 4(c)(2)(A) of the Endangered Species Act.
The Service is encouraging the public to submit any new information that becomes available concerning the status of, or threats to, the Bone Cave harvestman or its habitat for their consideration.
