It is now clear that the cow was found dead on Bjonholm in Houtskär have been killed by a bear. In all probability it is the issue of the same bear that killed two other cows on Lökholm in Iniö earlier in the week. Agriculture Secretary Susan Rehnström has examined the carcass on Friday afternoon, and it is clear that there is a bear who once again had been there. - The neck was broken, so it suggests that it has received a blow on the neck, said Rehnstrom. Muzzle was torn away and having consumed, the teats were also worn away, finds Rehnström. - Bear lag time the carcass in the water and let it rot for some time before the bear eats its prey. Rehnström therefore believe that the bear will return to their prey later. The cow has now killed at Bjonholm owned by the same farmer, Mats Eklund, who earlier this week lost two cows in Lökholm. Eklund has sought permission to shoot the bear, but such is under wildlife management consultant Jörgen Hermansson granted until August. Bjonholm is a paragraph from Mossala in Houtskär and Rehnström believes there is reason to move a little more cautious in Mossala woods right now. translate.google.pl/translate?js=n&prev=_t&hl=pl&ie=UTF-8&layout=2&eotf=1&sl=sv&tl=en&u=http%3A%2F%2Fsvenska.yle.fi%2Fnyheter%2Fsok.php%3Fid%3D134165%26sokvariant%3Darkivet%26lookfor%3DFyll%2520i%2520ett%2520s%25C3%25B6kord%2520h%25C3%25A4r!%26advanced%3Dyes%26starttid%3D%26sluttid%3D%26antal%3D10

"...DISCUSSION Cattle Depredation Our findings suggest that grizzly bears from most sex- age cohorts will opportunistically prey on cattle. Older- aged males were the most common depredator, but even within this cohort individual propensities varied. Among the 8 adult males we monitored, 5 killed <1 cattle each, while the remaining 3 were implicated in 90% of all iden- tifiable losses. Subadult males were the only group not associated with depredations, which may have been par- tially due to exclusion by adult males (Holm et al. 1999). Given the relatively high number of adult males we en- countered (8 of 17), adult male exclusion may also con- tribute to infrequent depredation by other grizzly bear sex-age classes. Our observations are similar to findings reported in other studies. Horstman and Gunson (1982) found that most cattle depredation by black bears in Alberta was by mature males. Knight and Judd (1983) found that relatively few adult grizzlies of both sexes killed cattle during their study. Claar et al. (1986) reported that 18 grizzlies they monitored did not kill cattle, but the 2 that did were both male (1 adult, 1 subadult). However, neither grizzly study (Knight and Judd 1983, Claar et al. 1986) reported individual depredation rates, thus it is un- known whether those bears were habitual or infrequent depredators of cattle. Black bears did not appear to depredate cattle during our study, which was surprising given the relatively high number of black bears we incidentally captured and were then monitored by Holm et al. (1999; 24 captured, 17 monitored). Although not frequently reported, several studies have documented black bear depredation on cattle (Davenport 1953, Roy and Dorrance 1976, Horstman and Gunson 1982, Bjorge 1983). Grizzly bears we monitored appeared to use different habitats than black bears, with differences most pronounced for areas occupied by adult male grizzlies (Holm et al. 1999). Thus, grizzlies may exclude black bears from cattle-occupied areas where these species occur sympatrically, thereby reducing the oppor- tunity for black bears to prey on cattle..." "... Over 50 years ago Murie (1948) con- cluded: "Because the grizzly range in the United States is now so greatly restricted it is believed by many that the grizzly should be given special consideration in this re- gion. A satisfactory solution will require land-use plan- ning on a high plane, with all social needs carefully considered." It seems little has changed. Grizzlies were apparently extirpated or greatly reduced from Wyoming rangelands shortly following Murie's study, but have re- cently returne .." www.bearbiology.com/fileadmin/tpl/Downloads/URSUS/Vol_13/Anderson_13.pdf

BEAR RELOCATIONS TO AVOID BEAR/SHEEP CONFLICTS INTRODUCTION Black bear predation on domestic sheep is a chronic problem for many western livestock producers. A recent survey of livestock predator problems revealed that bears killed approximately $450,000 worth of sheep and lambs in the U.S. in 1990. In Oregon, black bears destroyed an estimated 400 head of sheep and lambs valued at $17,800 in 1990 (NASS 1991). "... Incidental to our review of bear damage patterns, we noted that most damaging individuals were adult boars (Table 1). In 1989, 4 of the 27 bears taken in Oregon in response to livestock damage complaints were under the age of three while 18 were four years old or older (Trainer and Golly 1991). Approximately 85 percent of the "damage" bears were males (Table 1), even though the adult bear population probably contains more females than males. .." digitalcommons.unl.edu/cgi/viewcontent.cgi?article=1002&context=vpc16

Bear – human interactions studies Starting with 1991, there were collected data regarding conflicts with other fields of activities. This data, centralized at the Ministry of Agriculture, Forests and Rural Development, shows that yearly there were reported bear attacks on humans (related to grazing activities, forestry works and tourism), damages to livestock and orchards and damages to family farms all over Romanian bear distribution. In between 1990 and 1999, in all counties of Romania were the bears exist, there were collected data from the wildlife units of the forest administration and hunting association about the reported bear - human conflicts. If encounters with humans and killing of caws were all reported, killing of sheep, goats or pigs were sometime not considered worth enough to be notified. When people were involved in the conflicts' details were asked about the condition in which the confrontations took place. The study was conducted in Carpathian Mountains, in the 26 counties, were bear exist in Romania. These mountains are 60% covered by forests up to 1600 – 1800m high. Above the timber line there are alpine meadows and bushes and at the bottom of the mountains crop fields. Data were collected about 119 cases of man - bear conflicts, 18 persons were killed by bears and 101 injured. From the death accidents, 11 were connected with livestock conflicts, in the same period the killing of 3232 sheep, 1003 cows, donkeys and horses, 183 pigs and 140 goats was reported to be done by bears. The livestock breeders were visited and interviewed about management practices, prevention methods used, place and time of the kill and when possible necropsies were performed on animals killed by bears. The man - bear conflicts have as the main causes the human behaviour and the lack of knowledge about “How to act” when you meet a bear. The greatest numbers of conflicts are connected with livestock grazing. The alpine meadow management seems to be one of the principal problems in the high number of accidents. Due to the overgrazing, the carrying capacity decrease and more and more herds are grazing in the forest. These create the conditions for bear depredation directly on the herd during the day or on lost animals in the night. The shepherd's try to escape the animals with the help of the guardian dogs and very often they succeed. Sometimes the bears respond to these attaches and a great number of deaths and injuries result from this confrontation www.icas.ro/DOCS/Bear%20Management%20Plan.pdf

"He was verified by the Fish & Game Department as being killed by a grizzly. Notice how this is a nice big calf and NOT some weak, little, sick calf like some people would have you believe predators always eat. Typically a griz will bite the calf (sometimes they kill full grown cows or yearlings as well) across the withers (front shoulder area) and puncture the lungs and other vitals in this manner. Then they will proceed to eat them, sometimes burying part of the calf and coming back later. When they are done the calf will be completely skinned. The wolves will find the bones and crack them for the marrow inside. If the animal was killed by wolves they will often show bite marks around the flanks, the tail may be chewed off, the nose will be bitten and chewed on, and often the rectum is pulled out (the wolves often pull out the rectum while the animal is still alive)." realranchers.com/category/real-ranching/page/3/

ANDEANB EAR-CATTLEI NTERACTIONAS NDT REE NEST USE IN BOLIVIAA ND VENEZUELA Andean (spectacled)b ears (Tremarctoso rnatus)h ave been reporteda s livestockp redatorsth roughoutth eirr ange (Peyton 1980, Suarez 1988, Mondolfi 1989, Goldstein 1991a). In Peru, Peyton (1980) reported that in order to kill cattle, bears pursue the animals on steep slopes or near cliffs to make them fall. Peyton (1980) also acknowledged reports that a bear may carry livestock kills up a tree to consume it in seclusion and protect the kill from other animals. Even though cattle remains were found in Andean bear scats in Peru (Peyton 1980) and Ecuador (Suarez 1988), no field evidence was gathered to discriminate between predation and consumption of carrion by Andean bears. The use of tree nests (nest-like platforms) by Andean bears has been reported by several authors (Osgood 1914, Tate 1931, Bridges 1948, Mondolfi 1989, Goldstein 1991b). They described tree nests as ordered assemblages of bent or broken branches positioned in forked branches, resembling large nests and used as resting places. Peyton (1980) found 5 tree nests in Peru associated with fruit feeding. Based on his observationsi n Peru,P eyton( 1980) suggested that the platforms were used for feeding purposes rather than for resting, as had been reported. Although the use of tree nests in relation to fruit feeding is widely reported anecdotally by locals in Venezuela, field investigations have found that tree nests were strongly associated with cattle carcass feeding sites (Goldstein 1991b). No direct evidence of predation on cattle by Andean bears was gathered during the Andean bear surveys done between 1985 and 1987 in Venezuela. However, some evidence supports cattle predation by Andean bears (Goldstein 199 la), including signs of struggle (deep and long hoof marks on the ground, uprooted vegetation, cattle with claw marks), the number of cattle lost at each site, the absence of sign from otherp ossible predators,a nd the cessation of cattle losses after the killing of bears. This work reports new information on Andean bear-livestock predation claims, carcass feeding behavior, and tree nest use by Andean bear gathered from 1996 to 2000 in the Venezuelan Andes and in August 2000 at the Apolobamba National Parka nd surroundinga reas in Bolivia www.bearbiology.com/fileadmin/tpl/Downloads/URSUS/Vol_13/Goldstein_13.pdf

Andean Bear Project "...Beto, a male bear we released in July 2006, has been sighted a number of times pursuing livestock. There is no evidence that he has actually killed a cow for consumption, though we have found signs that there are bears killing and eating livestock in this area. I have personally seen bears attacking cows (see photo 1) and we have come across numerous remains of livestock that have been attacked by bears..."

www.flickr.com/photos/bobkh/387625744/sizes/l/in/photostream/Grizzlies have always been a fact of life in the valley around Hungry Hill. The handful of ranchers who make up the sleepy community just off Highway 16 in central British Columbia expect to lose a calf or two to the occasional marauding bear that wanders down from the eastern face of the Telkwa Mountain Range. It was never a big deal, just part of the cost of doing business. But everything changed on a hazy summer morning in 1998 when rancher Maxine Bell visited her grazing lease to check her herd and came upon a harrowing scene. She found a 1,500-pound cow that had been ripped apart like a feather pillow. Jagged bone fragments, bits of flesh and clumps of bloody hide were strewn over an area the size of a small corral. The set of huge tracks on the ground around the kill suggested that a big grizzly had ambushed its prey from the front, crushed the cow's skull with several blows from its powerful paws, and then gorged on the carcass before heading back into the bush. Unnerved by the ghastly sight and by the thought of such a brazen and seemingly vicious bear roaming the area, Bell immediately notified local authorities, including district conservation officer Kevin Nixon. A report of a grizzly kill wasn't unusual to Nixon, who works out of the Wildlife Branch's Smithers office. However, this bear was different from the rest. After driving to Bell's ranch, viewing the gory site and subsequently receiving word of more livestock predation in the same area over the next several weeks, Nixon and fellow officer Brad Lacey knew they had a big problem on their hands. In cases that involved grizzly depredation, protocol called for Nixon and Lacey to attempt to capture and relocate the bear to an even more remote area of the province. But since the bear had demonstrated a preference for Hungry Hill's vulnerable livestock, it would almost certainly return, even if moved hundreds of miles away. Consequently, the wildlife officers decided that when they did trap the bear, they would destroy it. Nixon recalled a grizzly sow and two cubs that terrorized local ranchers for a few months in 1988 before they vanished into the mountain foothills, although not before they had acquired a taste for beef. Nixon was convinced that the rogue bear they faced was one of the cubs that had visited the area with its mother more than 10 years before. Initial efforts to capture the bear involved setting traps around fresh livestock kills, which began to occur with greater frequency. Dead cattle were found in open pastures, overgrown meadows and even the deep forests that rimmed various ranches. Culvert traps, which are usually foolproof and effective, couldn't catch the nuisance grizzly. The next step for Nixon and Lacey was to place a series of spring-loaded cable snares around recently located carcasses. If stepped on, the snares would "jump" off the ground and cinch down on the bear's upper leg, anchoring it to a tree. But things never went as planned. Time after time, the bear managed to avoid the snares, frustrating the two officers and earning the cagey animal a reputation among locals as the "phantom grizzly" that couldn't be caught. As the months of disappointment for Nixon and Lacey turned into a year of frustration, the two wardens decided to change tactics. In an attempt to steer the bear directly into their snares, they built a giant "cubby set"-a larger version of the type fur trappers use for foxes and raccoons. Upon arriving at the scene of the latest kill, a steer, they dragged the carcass under the drooping boughs of a large spruce, secured it to the trunk and set about stacking heavy logs on three sides of it. In order to get at its kill, the boar grizzly would have to pass through the narrow entrance, which was rigged with three snares. .. more........ www.outdoorlife.com/articles/jon-farley/2007/09/phantom-hungry-hill
