    CircumArctic Collaboration to Monitor Caribou and Wild Reindeer

    Get PDF
     Caribou and wild reindeer (Rangifer) are integral to ecology and Aboriginal lives and culture in circumArctic regions. Since reaching peak size in the 1990s, most herds have been declining, while their ranges are changing as the footprint of people’s activities expands and the climate warms. More than ever, then, people need to share information and experience on Rangifer management and conservation. In recognition of this need for a circumArctic approach to monitoring, the CircumArctic Rangifer Monitoring and Assessment (CARMA) network, a relatively informal group of scientists, community representatives, and management agencies, was established in 2004. CARMA emphasizes collaborating and sharing information on migratory tundra Rangifer and developing tools to deal with the impacts of global changes on these herds.   Le caribou et le renne sauvage (Rangifer) jouent un rôle intégrant dans la vie et la culture autochtones des régions circumarctiques ainsi que dans l’écologie de ces régions. Depuis que la taille des troupeaux a atteint son summum dans les années 1990, la taille de la plupart des troupeaux diminue et leur parcours naturel se modifie en raison de l’expansion des activités humaines et du réchauffement climatique. C’est pourquoi plus que jamais auparavant, il est important de partager information et expérience au sujet de la gestion et de la conservation du Rangifer. Dans cette optique, un réseau de surveillance circumarctique a été établi en 2004, soit le réseau CircumArctic Rangifer Monitoring and Assessment (CARMA), dirigé par un groupe relativement informel de scientifiques, de représentants de la communauté et d’organismes de gestion. Le réseau CARMA met l’accent sur la collaboration et le partage d’information concernant le Rangifer migrateur de la toundra ainsi que sur la mise au point d’outils pouvant faire face aux incidences des changements planétaires qui ont un effet sur ces troupeaux

    Arctic Borderlands Ecological Knowledge Cooperative: can local knowledge inform caribou management?

    While quantitative analyses have traditionally been used to measure overall caribou herd health, qualitative observational data can also provide timely information that reflects what people on the land are observing. The Arctic Borderlands Ecological Knowledge Co-op (ABEKC) monitors ecological change in the range of the Porcupine Caribou Herd (PCH). The community-based monitoring component of the Co-op’s mandate involves the gathering of local knowledge through interviews with local experts in a number of communities.We analyzed the responses to interviews collected during 2000–2007 related to caribou availability, harvest success, meeting needs and caribou health during fall and spring. Interviews revealed 1) caribou greater availability during the survey period, 2) an increasing trend in the proportion of harvesters that met their needs 3) no trend in animals harvested or proportion of successful hunters and 4) improving overall caribou health throughout the period.There was no population estimate for the herd between 2001 and 2010. In 2001, 123,000 caribou were estimated in the herd. Based on an estimated 178,000 in 1989, a declining trend of ~ 3% annually occurred at least until 2001. In the interim agencies and boards feared the herd continued to decline and worked towards and finalized a Harvest Management Plan for the herd. In contrast, from the Co-op interviews all indications suggested improving herd conditions throughout most of the decade. A successful survey in 2010 determined the herd had grown to 169,000 animals. We conclude that the community-based interviews provided a valid, unique information source to better understand caribou ecology and express community perceptions of overall herd status and could provide a valuable contribution to management decision making.  We recommend that ABEKC results become standard input into Porcupine Caribou harvest management decisions and serve as a model of integrating community based monitoring data into resource management decision making throughout the north
