Salmon (Oncorhynchus spp.) is a key dietary item for temperate coastal Brown Bears (Ursus arctos) across much of their circumpolar range. Brown Bears living in Arctic, interior, and montane environments without large annual runs of salmon tend to be smaller bodied and occur at much lower densities than coastal populations. We conducted ground and aerial surveys to assess whether Brown Bears fished for salmon above the Arctic Circle, in and around Gates of the Arctic National Park and Preserve. Here, we document the use of salmon by interior Brown Bears in the Arctic mountains of the central Brooks Range of Alaska. We believe our findings could be important for understanding the breadth of the species’ diet across major biomes, as well as visitor safety in the park and Brown Bear conservation in the region.

The Himalayan brown bear (Ursus arctos isabellinus) is considered as .Endangered. in Pakistan. However, a small population of this species still exists in northern Pakistan including Azad Jammu and Kashmir (AJK). A study was conducted to determine population status and distribution of Himalayan brown bear in Musk Deer National Park (MDNP), from April 2011 to September 2012. MDNP, covering an area of 528.16 km2, is situated in the extreme north of AJ&K (upper Neelum Valley) about 155 km away from Muzaffarabad. Study area was divided into three zones (Phulawai, Sardari and Loser) and searched for brown bear signs and evidences. A total of 17 transect surveys were carried out to collect the data on current population status and distribution of Himalayan brown bear in the study area. In addition, questionnaires based surveys were carried out in the area to gather maximum information about this species. Based on direct and indirect signs collected, a total population of about 12 individuals with a population density of 0.42 bear/km2 was estimated in the MDNP with maximum (0.45 bear/km2) in Loser and minimum (0.37 bear/km2) in Phulawai zone. Altitudinal preference was recorded highest (0.46 bear/km2) at the elevation level of >3000 m asl. For the proper management and conservation of Himalayan brown bear, more comprehensive study should be carried out throughout its potential habitat.

AbstractHuman–bear conflicts resulting from livestock depredation and crop use are a common threat to the brown bear Ursus arctos throughout its range. Understanding these conflicts requires the recording and categorization of incidents, assessment of their geographical distribution and frequency, and documentation of the financial costs and the presence of any preventative measures. Damage compensation schemes can help mitigate conflicts and, in some cases, improve acceptance of bears. This study aims to elucidate the major factors determining the patterns of damage caused by bears, examine the effectiveness of preventative measures in reducing such damage, and identify bear damage hotspots in Croatia. Our analysis is based on damage reports provided by hunting organizations to the Croatian Ministry of Agriculture during 2004–2014. The highest number of claims were made for damage to field crops and orchards. Damage to livestock, agricultural crops and beehives resulted in the highest total cost to farmers. Damage to beehives and to automatic corn feeders for game species incurred the highest cost per damage event. We identified a hotspot for bear damage claims in Croatia, located near Risnjak National Park and the border with Slovenia. Damage appears higher in areas that have more villages closer to protected areas and a greater per cent of forest cover, indicating a synergistic effect of protected environments that facilitate bear movements and the presence of human activities that provide easily accessible food for bears.

Food Conditioning

Abstract This paper investigates the awareness of visitors to Bieszczady National Park (BNP) and Tatra National Park (TNP) of human influence on brown bears (Ursus arctos Linnaeus, 1758), i.e. what causes human-habituated bears to become food-conditioned. In the parks studied, 928 questionnaires were collected in July and August 2007. The survey was supplemented with data on the amount of garbage collected in both parks by municipal services in 2007. Respondents in BPN displayed significantly greater knowledge about the causes of human-food conditioning of bears than respondents in TNP (64.2% and 52.7%, respectively, had more than the average of 3.54 correct answers per 5 questions in the questionnaire). As many as 60.1% of visitors in both parks incorrectly associated human-food conditioning with a lack of natural food and 34.4% withan excessive number of bears. Most respondents did not realise that to prevent human-bear conflict, decisive actions must be taken towards every food conditioned bear observed in the free-living population. Unlike in BNP, in TNP there is a large amount of rubbish left by visitors along trails. In 2007, municipal services collected in both parks a similar amount of garbageper 1000 visitors (0.39 m3 and 0.37 m3 in BNP and TNP, respectively) but the annual number of visitors is nearly 8‑fold lower inBNP than in TNP. In BNP, only visitors put rubbish in containers, while in TNP, additional 6 cleaning companies are employed to collect rubbish thrown by visitors along trails. In contrast to TNP, however, in BNP there are no bear-proof containers. Both parks need to prevent the access of bears to rubbish. It is also advisable to initiate an effective information campaign among visitors about prevention of human-food conditioning of bears.

Abstract Food consumed by brown bears in the Golestan National Park in Iran was analyzed during autumn 2011. We identified 22 food items in 61 scats, with the most important food items being hawthorn fruit, cherry plum fruit and chestnut-leaved oak hard mast, based on importance value (IV) estimates of 26.4%, 18.1% and 12.9%, respectively. The overall bear diet (percent digestible dry matter) was composed of 77.9% soft mast (i.e. fruit), 21.3% hard mast and small proportions of other vegetation (0.3%) or animal matter (0.4%). One anthropogenic food was identified (vine grape) and was of minor importance (IV=0.2%).
