“…Interestingly, the probability of high recovery potential under the current conditions, and with even a large translocation effort, are roughly consistent with the 50% failure rate of caribou translocations in eastern North America (Bergerud & Mercer, 1989;Gogan & Cochrane, 1994) as well as estimates of translocation success in western North America (Decesare et al, 2011). However, the mechanisms leading to that result vary from one application to another, so we cannot claim that our model emulates or explains the more general result of many historic translocations.…”

“…The long-term success of translocations requires managing the behaviour, habitat, metapopulation, and ecosystem level issues that initially led to the decline of the population (Armstrong & Seddon, 2008). Since 1982, the Ontario Ministry of Natural Resources and Forestry has restored or introduced woodland caribou from the Slate Islands to a number of islands and the shoreline of eastern Lake Superior with little success (G. Eason, personal communication; Gogan & Cochrane, 1994). Failures of caribou translocation projects have been attributed to disease, predation, anthropogenic disturbance and/or insufficient and fragmented habitats (Bergerud & Mercer, 1989;Gogan & Cochrane, 1994;Compton et al, 1995).…”

In a review of 33 caribou introductions in eastern North America from 1924 to 1985, introductions inevitably failed when animals, released in proximity to white-tailed deer (Odocoileus virginianus), contracted meningeal brain worm (Parelaphostrongylus tenuis) and died (Bergerud & Mercer, 1989).…”

“…Predation was also a key factor in failed translocations. Wolf (Canis lupus), cougar (Felis concolor), and occasionally bear (Ursus americanus) predation were credited with the loss of translocated caribou in Ontario, Quebec, and British Columbia in Canada and Maine in the United States (Bergerud & Mercer, 1989;Gogan & Cochrane, 1994;Compton et al, 1995). Cougar predation was the primary cause of death for 60 woodland caribou translocated from British Columbia to northern Idaho between 1987and 1992(Compton et al, 1995.…”

“…Cougar predation was the primary cause of death for 60 woodland caribou translocated from British Columbia to northern Idaho between 1987and 1992(Compton et al, 1995. Wolf predation caused the failure of translocations in the Lake Superior region, Ontario, including the Gargantua Peninsula (39 caribou released in 1989) (Gogan & Cochrane, 1994) and Bowman Island (6 caribou released in 1985) (Bergerud & Mercer, 1989). Predation is also the primary limiting factor for almost all natural woodland caribou populations (McLoughlin et al, 2003;Wittmer et al, 2005;Festa-Bianchet et al, 2011).…”

The 15th North American Caribou Workshop (NACW) was held from 12-16 May 2014, in the traditional territories of the Kwanlin Dün First Nation and the Ta’an Kwäch’än Council, in Whitehorse, Yukon, Canada. This biennial meeting is the largest technical conference of its kind dealing specifically with caribou biology and management. The first NACW was held in Whitehorse over three decades ago in 1983, and 13 subsequent workshops have been held across North America until now. With nearly 400 delegates from Canada, the United States, Norway, and Greenland attending the 2014 conference, it is evident that this “North American” gathering has truly become an international event. Furthermore, delegates attending this 15th NACW represented federal, provincial, territorial, state and First Nation governments, academia, non-governmental organizations, co-management boards and councils, private consultants, and industry, creating a relatively unique conference setting bringing together a variety of perspectives and concerns. The breadth of the participants in terms of geography, expertise and affiliation resulted in a rich base of human capacity to discuss issues related to caribou conservation and management.Given that it had been nearly three decades since the inception of this workshop, and with its return to the location of the first NACW, the organizing committee felt it was a fitting opportunity to look back and assess what had been achieved with respect to caribou conservation and management. As such, the theme of the 15th NACW was “Caribou Conservation and Management: What’s Working?” The opening session of the conference focussed on invited presentations explicitly addressing this question, and included topics on structured decision making, forest management, harvest monitoring, carnivore management, regional land use planning and management, and aboriginal perspectives on a long-term collaborative caribou recovery program in the southwest Yukon. We challenged our speakers to share what was working and why, and the information provided was valuable and timely, prompting many questions and discussion throughout the conference.

Inherent Rarity in Community Restoration

We explore the implications of an often overlooked fact in community restoration: most species, in real or synthetic communities, are infrequent or rare, a phenomenon we call “inherent rarity.” Whether from long‐term interactions of many factors affecting birth, death, and establishment within natural communities, or from short‐term interactions of recently created communities, species abundance distributions are roughly lognormal or even more attenuated. The greater the predisturbance species diversity of remnants or the planting diversity of restorations, and the smaller the area of a habitat patch, the more likely a large proportion of species will exist in populations so small that they are acutely or chronically vulnerable to local extinction. We suggest that habitat fragmentation will inevitably favor plants and animals that are highly mobile, early successional species, including many exotic weeds among plants, or species that are historically organized as metapopulations that happen to be common enough to function as such. We further explore rationales for countering the effects of inherent rarity, including connectivity from buffers, corridors, and stepping stones, and dominance suppression from seasonally appropriate mowing, grazing, or fire.

Synthesis and Assessment of the Folsom Record in Illinois and Wisconsin

2016

Census of avocational and public collections for Folsom and Midland artifacts from Illinois and Wisconsin signals a substantial Folsom occupation in the Upper Midwest. Over 200 points and preforms demonstrate a southwest-northeast pattern of point manufacture, use, discard, and loss across much of Illinois and the southern third of Wisconsin. The distribution of these artifacts overlaps to a large extent; however, most Midland points occur in Wisconsin. This non-fluted weaponry is interpreted as a techno-situational response to the intrinsic properties and distribution of regional toolstones, combined with the relatively high cost of fluting failure experienced during periods of focused hunting. Folsom mobility and land use are structured along major rivers, with southern Wisconsin most often functioning as a main destination of group movement. Woodland caribou (Rangifer tarandus) are the inferred focal prey and organizational driver of Folsom adaptations in the Upper Midwest.
