Brown Bear Habituation to People: Safety, Risks, and Benefits by Stephen Herrero, Tom Smith, Terry D. DeBruyn, Kerry Gunther, and Colleen A. Matt A paper on the current thinking about the habituation of brown bears. |

Bear-Human Conflict in Alaska, 1900-2002 For the past several years Tom Smith and Steve Herrero have worked to construct a database of Alaska bear-human encounters spanning the 20th century. Currently, the database contains 500 incidents with 85 variables of information per incident, totaling over 17,000 individual data entries. The purpose of this research has been to promote bear conservation and human safety through minimizing conflict. |

Interagency Grizzly Bear Study Team Annual Reports The contents of these Annual Reports
summarize results of monitoring and research from the 1989-2005
field seasons. The reports also contain a summary of nuisance grizzly
bear (Ursus arctos horribilis) management actions. The study team
continues to work on issues associated with counts of unduplicated
females with cubs-of-the-year (COY). These counts are used to establish
a minimum population size, which is then used to establish mortality
thresholds for the Recovery Plan (U.S. Fish and Wildlife Service
[USFWS] 1993).
