Franklin’s bumble bee on edge of extinction
Robbin Thorp of the University of California, Davis, has been tracking the critically imperiled Franklin's bumble bee (Bombus franklini) since 1998. Surveys for Franklin's bumble bee clearly show declining population. Sightings decreased from 94 in 1998 to 20 in 1999 to 9 in 2000 to one in 2001. Sightings increased slightly to 20 in 2002, but dropped to three in 2003. Thorp saw none in 2004 and 2005; one in 2006; and none since. "I am still hopeful that Franklin's bumble bee is still out there somewhere," said Thorp, emeritus professor of entomology. "Over the last 13 years I have watched the populations of this bumble bee decline precipitously. My hope is this species can recover before it is too late."
