The goal of the Bear Specialist Group is to promote the conservation of bears and the habitats that they require across their distribution world-wide.

Who we are

The Bear Specialist Group (BSG) is one of more than 140 Specialist Groups established by the Species Survival Commission (SSC), within the International Union for the Conservation of Nature (IUCN). The goal of the BSG is to promote the conservation of bears and their natural habitats across their distribution worldwide. The BSG and IBA are closely affiliated. Members of the Bear Specialist Group are appointed by the BSG co-chairs and are provided membership benefits of the IBA.

Dave Garshelis

United States of America

Dave is a Wildlife Research Scientist with the Minnesota Department of Natural Resources (MDNR). Since 1983, as bear project leader for the MDNR, he has conducted population and ecological studies of American black bears across their geographic range in Minnesota, with direct application in management of the state’s bear population. As an adjunct professor at the University of Minnesota, he has advised graduate students on studies of most of the other bear species of the world, aimed at improved conservation. Previously he studied black bears in the Great Smoky Mountains for his M.S. degree (University of Tennessee) and sea otters in Alaska for his PhD (University of Minnesota). His current interests are in monitoring trends of bear populations, discerning factors limiting population growth, and understanding ecological adaptations of bears, especially in human-modified environments or at the edge of their geographic range.

Michael Proctor


Mike is an independent Canadian bear research ecologist. He completed his PhD in grizzly bear ecology in 2003. He currently researches and implements conservation solutions for small threatened brown bear populations that span the Canada-US border from southern British Columbia. The Trans-border Grizzly Bear Project is an international cooperative effort that uses DNA survey methods and GPS telemetry to identify broad and fine scale population fragmentation, assess and monitor population status, identify core and linkage habitat, and understand habitat use, food modeling, and security through GIS-based habitat modeling of GPS telemetry and DNA survey data. His work also includes efforts to reduce bear-human conflicts. Mike is interested in translating sound scientific research on threatened bear populations into workable conservation solutions. Beyond Canada, he has worked in international bear projects in Ecuador, Italy, and Mongolia.

Darcy, BC, Canada

+1 6044523233

Bruce is Wildlife Research Ecologist for the British Columbia Ministry of Forests. For over 30 years, his work has focused on integrating the ecological requirements of grizzly bears and endangered mountain caribou with human developments. In doing so, he has conducted ecological studies of grizzly bears in several parts of the province and mountain caribou across most of their distribution. Bruce’s work has led him directly into the middle of the complex interface between people using the land and the conservation of two challenging species. Due to his knowledge of bears and caribou (plus the plants and animals that affect them), he has been involved with several, multi-stakeholder landuse planning processes that covered large portions of the Province. Bruce was previously president of the International Association for Bear Research and Management and through this role became linked to many bear conservation issues world-wide. His interests remain the same – how to maintain challenging species in spite of expanding human demands on the land.

Originally from the UK, Matt has been living in Southeast Asia since 2001. He has been working with wild animals for over 25 years, initially in zoos and wildlife parks but for the past 15 years his work has been focused on combatting the illegal wildlife trade. As Chief Executive of Free the Bears, he is responsible for overseeing projects and partnerships in six countries throughout Asia, developing world-class bear sanctuaries, training local teams to provide optimal care and promoting environmental awareness in some of the world’s least developed countries. Matt believes that long-term conservation of wildlife in Southeast Asia will only be achieved through a combination of strengthened law enforcement and improved environmental awareness. To this end his work is increasingly focused on developing capacity for local researchers to fill gaps in our understanding of wild bears, support and training for government-led law enforcement teams, and fostering public support for conservation initiatives through innovative education programmes.

With a strong belief in the need for evidence-based conservation, Brian has spent much of the past ten years implementing research projects designed to improve understanding of Asiatic black bears and sun bears in the region. Currently, for his PhD, Brian is evaluating population monitoring techniques as a key component of adaptive conservation strategies. Working closely with the Bear Specialist Group, he conducted the first nationwide surveys of bears in Vietnam and played a lead role in developing the Sun Bear Conservation Action Plan – the first range-wide action plan for a terrestrial bear species, integrating in-situ and ex-situ conservation efforts. Brian has a keen interest in the role that ex-situ research can play in improving animal welfare and species conservation, and is actively involved in facilitating student research at Free the Bears sanctuaries. To help combat the major threat posed by illegal trade, Brian coordinates pioneering social science research designed to more effectively change behaviours in order to reduce demand for bear bile and secure a sustainable future for bears in Southeast Asia.

+49 221 77 85 107

Lydia is curator for ursids and felids at Cologne zoo and supervises projects on applied ethology and behavioural ecology. The research projects focus on the effects of environmental and social factors on resource use and activity patterns of captive herbivores and carnivores. The projects aim to assess the quality of the keeping conditions, to reveal problems which might indicate an overcharge of the adaptation potential, and test solutions to overcome these problems. Results on bears were implemented into the husbandry guidelines for ursids which were published during her tenure as co-chair of the Bear Taxon Advisory Group (TAG) of the European Zoo and Aquarium Association. The standards set by the guidelines served as a basis for regional collection planning for ursids and assessment of carrying capacity. Within the frame of the European Bear TAG she is also involved in ex situ conservation programmes for ursids by co-ordinating the European Endangered Species Breeding Program (EEP) of the spectacled bear and keeps the studbook for sun bears in Europe. Lydia finished her diploma in 1977 and obtained her doctoral degree in 1984 from the Albertus-Magnus University in Cologne, where she gives lectures and courses on zoo biology and applied ethology.
