Predator-prey systems are complex and attempts to manage them to benefit woodland caribou populations have generated mixed results. Despite limited success, calls for wolf control continue because of the urgent need to reverse the decline of woodland caribou populations, and because there are so few management options available that have the potential to demonstrate immediate benefits. I present the results of a policy analysis that reviews the potential role of wolf control within the ecological, social and political context of northeast British Columbia (BC). The scale and scope of a wolf control program is ultimately limited by the economic and ethical support of the public, while the program’s effectiveness is governed by the conditional dependencies among the major factors effecting woodland caribou declines. The policy analysis suggests that the contribution of wolf control programs to caribou conservation efforts in northeast BC will be limited, but that significant uncertainties in the causal pathways resulting in caribou population declines limit our ability to propose alternative management policies that have a high confidence of success.

The federal Recovery Strategy for the Woodland Caribou (Rangifer tarandus caribou), Boreal Population in Canada, identifies coordinated actions to reclaim woodland caribou habitat as a key step to meeting current and future caribou population objectives. Actions include restoring industrial landscape features such as roads, seismic lines, pipelines, cut-lines, and cleared areas in an effort to reduce landscape fragmentation and the changes in caribou population dynamics associated with changing predator-prey dynamics in highly fragmented landscapes. Reliance on habitat restoration as a recovery action within the federal Recovery Strategy is high, identifying 65% undisturbed habitat in a caribou range as the threshold to providing a 60% chance that a local population will be self-sustaining. In alignment with the federal Recovery Strategy, Alberta’s Provincial Woodland Caribou Policy identifies habitat restoration as a critical component of long-term caribou habitat management. Habitat restoration initiatives of Alberta’s historical industrial footprint within caribou ranges began in 2001 and have largely focused on linear corridors, including pipelines. Initiatives include revegetation treatments, access control programs and studies, and restricting the growth of plant species that are favourable to moose and deer, the primary prey for wolves. Habitat restoration for pipelines also includes pre-construction planning to reduce disturbance and create line-of-sight breaks, and construction techniques that promote natural vegetation recovery. Lessons learned from habitat restoration programs implemented on pipeline projects in northeastern Alberta will be shared as an opportunity to improve common understanding of restoration techniques, the barriers to implementation, and potential outcomes.

ABSTRACTStrategy DOTS is the tuberculosis control programs. The program has implemented in Tanah Kalikedinding Health Center and has expected to reach CDR ≥ 70% and SR ≥ 85%, which closely related to the management of health centers. This study aimed to evaluate the implementation of the DOTS program in health center whose the results associated with indicators of tuberculosis. This was a descriptive design study with the population was all pulmonary specialist, tuberculosis officers and laboratory personnel and pulmonary tuberculosis patients. The number of Tuberculosis patient respondents was 32 respondents. Samples were chosen using purposive sampling. Data collected by interview questionnaire and checklist. The variables were the finding case, the TB treatment, the enabling factor and inhibiting factor, recording and reporting, and result of tuberculosis indicators. This study resulted that CDR in 2013 was 112% already reached the national target ≥ 70%. This success related to the finding case almost all patients > 2 weeks of cought and all (100%) patients were examinated sputum and diagnosed according to the steps of tuberculosis diagnosis in Indonesia Department of Health guidelines. While SR in 2013 was 65.5% did not reach the target ≥ 85%. It was caused of there are patients who did not have a taking drug observer (PMO). All (100%) patients ever forgot taking anti tuberculosis drugs. Change in schedule of visit to the continuation phase be 2×/month caused patients to forget taking anti tuberculosis drugs. The enabling factor was counseling routinely by health care workers in health center. Inhibiting factor was distance to health center by majority (65,5%) patients were > 1 km. So they needed vehicle to go to the health center. Recording and reporting using electronic systems and being reported by online. So it is expected all TB patients were expected have a taking drug observer and optimizing the role of the a taking drug observer to increase success rate.Keywords: DOTS strategy, Case Detection Rate, Success Rate, evaluation,                     Tuberculosis

Habitat Alterations

Large-scale habitat loss is frequently identified with loss of biodiversity, but examples of the direct effect of habitat alterations on changes in vital rates remain rare. Quantifying and understanding the relationship between habitat composition and changes in vital rates, however, is essential for the development of effective conservation strategies. It has been suggested that the decline of woodland caribou Rangifer tarandus caribou populations in North America is precipitated by timber harvesting that creates landscapes of early seral forests. Such habitat changes have altered the predator-prey system resulting in asymmetric predation, where predators are maintained by alternative prey (i.e. apparent competition). However, a direct link between habitat condition and caribou population declines has not been documented. We estimated survival probabilities for the threatened arboreal lichen-feeding ecotype of woodland caribou in British Columbia, Canada, at two different spatial scales. At the broader scale, observed variation in adult female survival rates among 10 distinct populations (range = 0.67-0.93) was best explained by variation in the amount of early seral stands within population ranges and population density. At the finer scale, home ranges of caribou killed by predators had lower proportions of old forest and more mid-aged forest as compared with multi-annual home ranges where caribou were alive. These results are consistent with predictions from the apparent competition hypothesis and quantify direct fitness consequences for caribou following habitat alterations. We conclude that apparent competition can cause rapid population declines and even extinction where changes in species composition occur following large scale habitat change. © 2007 The Authors.

Winter Range

Initial long term planning for logging on the Tweedsmuir-Entiako caribou winter range began in the early 1980s. Because little information was available on which to base winter range management, the British Columbia Fish and Wildlife Branch began studies on radio-collared caribou in 1983, and an intensive study on caribou winter habitat requirements was conducted from 1985 to 1988. Terrestrial lichens were identified as the primary winter food source for the caribou, and in 1987, caribou winter range ecosystem maps, which emphasized abundance of terrestrial lichens, were produced. The ecosystem maps and information from the caribou study, including potential direct and indirect effects of timber harvesting on the caribou population, were used to develop a management strategy for the winter range. The management strategy comprised two levels of management: a landscape level (Caribou Management Zones); and a site-specific level (caribou habitat/timber values). Timber information associated with BC Ministry of Forests forest cover maps was integrated using a Geographic Information System. Six winter range management options were proposed ranging from harvesting low value caribou habitats only throughout the winter range to total protection of the entire winter range. Impacts of those options on both the caribou population and on the timber supply were evaluated. The options were reviewed through a public planning process, the Entiako Local Resource Use Plan, and recommendations from that process were forwarded to the British Columbia Protected Areas Strategy.
