What are Human-Dimensions?
Wildlife issues are complex. While human behavior may contribute to conflict with wildlife, people are also key to meaningful conservation and management actions. Such conservation efforts require a comprehensive understanding not only of ecology and wildlife biology, but also of policy, socioeconomic factors, cultural and social values, and other dimensions of human behavior.
The CDFW's Human-Dimensions of Wildlife Conservation (HD) Unit is a collaborative program conducting interdisciplinary research to better manage California’s natural resources. HD research investigates the role that people play in wildlife management and conservation, actions and decision-making, using comprehensive social and environmental sciences.
Role of Human-Dimensions Research
The factors that shape how human-wildlife interactions may be perceived, and whether they escalate to conflict, are complex. Some people enjoy the presence of wildlife and may tolerate regular interactions. Other people may have minimal interaction, but do not tolerate even the presence of wildlife. This variation in tolerance is often poorly understood.
Research and monitoring of the different facets of human-wildlife conflict, which may include wildlife health, human dimensions, public safety, and reporting trends, are important. Of note, is the strong seasonal pattern of most human-wildlife conflicts. For more information on how to address unwanted human-wildlife interactions, visit the CDFW Human-Wildlife Conflicts page.

Recruit. Retain. Reactivate.
Hunters provide some of the strongest support for wildlife conservation projects. In recent decades, California and the rest of the nation has seen a decline in the number of hunters. The Recruit. Retain. Reactivate (R3) program is a collaborative effort between CDFW and diverse partners to help address this decline. The HD Unit helps to provide the social science tools to examine trends and patterns across a wide range of outdoor recreational activities including hunting, , foraging, and wildlife viewing.

A Changing California
Climate Change
The Drought Response Implementation Plan (DRIP) was created in 2015 in response to extreme drought conditions in California and how it may impact human-wildlife interactions. Between September 1, 2015, and June 30, 2017, every report about human-wildlife interactions received by CDFW staff was recorded and documented. Approximately 30,763 reports were documented and categorized into one of six categories: public safety, perceived public safety, property damage, animal welfare, general nuisance, and sighting. The HD Unit is using this data to examine trends in reporting of human-wildlife interactions during drought. Since 2017, an online Wildlife Incident Reporting System (WIR) has replaced DRIP protocol for documenting and compiling conflict reports.
Social and Cultural Change
Wildlife Rehabilitation
California is fortunate to have a diverse community of passionate wildlife rehabilitation workers and volunteers that care for injured, sick, and orphaned wildlife. Wildlife rehabilitation centers are permitted through CDFW's Wildlife Welfare and Rehabilitation Program. Human dimensions research can help wildlife rehabilitation efforts by identifying what information and resources rehab volunteers need to care for wildlife.
