Bears, specifically black bears, come out of hibernation in April 鈥� and they are hungry.
According to Meg Toom, 老澳门六合彩开奖记录资料鈥檚 community coordinator for WildSafeBC, they have lost a third of their weight by spring.
鈥淚t鈥檚 not muscle weight; it鈥檚 the fat they鈥檝e stored before going to den in the winter. They鈥檙e not exactly lean, but they鈥檙e hungry.鈥�
Yes, I can imagine they would be plenty hungry after a four-month fast, and looking for food to replenish that fat loss.聽 So what does a large mammal eat to replenish 100 to 200 kilos of fat?
鈥淚t depends on the weather, but mainly dandelions, grass, berries, it鈥檚 basically salad.鈥�
Well, who says you can鈥檛 put on weight eating salad? The trick though, is you have to eat a lot of it. And just like humans, the attraction of easy, high caloric food 鈥攋unk food 鈥� is hard to resist if available.聽 With bears, junk food is human garbage. Last spring鈥檚 cold, wet weather delayed the growth of natural black bear foods, and that may have contributed to an attack in the Garibaldi Highlands.
鈥淥pen garbage, bird feeders, those are sources we don鈥檛 want them to become food-conditioned to. Bears are intelligent, curious animals they will take advantage of human food resources if given the chance,鈥� explains Toom.
In 2005 the District, in cooperation with Carney鈥檚 Waste Systems introduced the lockable garbage tote. Unfortunately, the brass carabiners on those totes were not as impregnable to bears as originally thought, and are now being replaced with more durable stainless steel locks. By all reports, they are having great success in preventing bear incursions with those (they are tested by WildSafeBC), and the replacement of the brass carabiners continues.
Black bear encounters are the most reported wildlife encounter to conversation officers, at 82 per cent of all calls or 472 total reports in 2017 (cougars are second at eight per cent and coyote鈥檚 at three per cent).
Last May was a particularly active month for black bear encounters with 109 calls to conservation officers, over previous years鈥� averages of 35.
鈥淏ears know you are there even if you don鈥檛 see them, they hear you, smell you. Eventually, it starts to erode their natural weariness, and they can get curious.鈥� Toom advises, 鈥測ou never want bears to feel comfortable around humans.鈥� That means being loud out on the trails, and not just with bear bells. 鈥淯se your voice, be loud, let them know you鈥檙e out there.鈥�
There lies much of the challenge in 老澳门六合彩开奖记录资料 when it comes to managing human and wildlife interaction. 老澳门六合彩开奖记录资料, it鈥檚 no secret, has an inordinate amount of active people. Mountain biking season is already here, and with it, dozens, if not hundreds of enthusiasts out on wilderness trails, add in dedicated hikers and trail runners and it can be a challenge to limit human/bear conflict.
Last year, when a mother bear and her two cubs took up residence for the spring and summer near the Mashiter Trail above the Highlands, the District and WildSafeBC took the proactive measure of putting up signs. Making trail users aware of the wildlife in the area, and recommending precautions.
鈥淭hey were habituated to humans, but not food conditioned, that鈥檚 when you get a high potential for conflict.鈥� Toom sees the result as a success, with bears living relatively close to humans, but sticking to wild food sources and not becoming nuisance bears.
鈥淪he鈥檒l be kicking out her cubs this year now that they鈥檙e yearlings, so hopefully they will continue the way they have, and avoid human food sources.鈥�
Toom adds that often people 鈥榢ill鈥� bears with kindness. They treat encounters with bears as a wildlife viewing opportunity, taking pictures, standing around watching them quietly. This only adds to bear habituation and can encourage a bear鈥檚 natural curiosity. They might start to approach people, or in some cases become aggressive. Although that is not their natural tendency, black bears evolved to be cautious and even shy, but there鈥檚 a limit. They are omnivores and opportunistic eaters, sometimes they will hunt small mammals, but are just as happy to scavenge dead carcasses left by more dedicated predators, like cougars.
According to Stephen Herrero, author of Bear Attacks: Their Causes and Avoidance, long considered the most definitive work on bear/human conflicts, playing dead in the face of a black bear attack is simply presenting yourself as an hors-d鈥檕euvre.
While Black bear attacks are rare, an aggressive black bear, unlike with grizzlies, are best met with as much aggression as you can muster, according to Herrero.
鈥淏lack bears usually show defensive behaviour before they become aggressive. It can start with chuffing sounds, which is them saying, 鈥榶ou鈥檙e too close, I鈥檓 uncomfortable.鈥� They may also get on their hind legs, which is not a sign they鈥檙e going to attack, it means they are trying to figure things out, pick up scents, get a better view,鈥� says Toom.
You cannot outrun a bear as they can run as fast as 40 kilometres per hour and can climb trees almost as fast. However, those abilities are usually employed to avoid people, not stalk them. But says Toom, younger bears, under five, can find themselves in unwanted circumstances simply due to their inexperience. This means, we humans have to be the adults and take measures to avoid encounters.
鈥淏e alert when out on the trails,鈥� says Toom. If you see fresh scat, you know bears or a bear are in the vicinity, so make lots of noise, and give them the chance to get out of the area.鈥�
She adds that if you do encounter a bear you should back away slowly, if it is persistent, then deploy bear spray. If you don鈥檛 have bear spray (f you are a regular on the trails you should), then throw rocks. Also, in bear country, Toom stresses, never let your dog off leash.
Despite being large mammals, bears can and do live near urban areas. Their populations are very healthy, but allowing them food rewards will only lead to their destruction.
As Toom explains, 鈥渉uman food sources can jack up bear populations.鈥� If bears come to rely on that, they will need human food sources to support their population beyond what natural sources would otherwise support.
鈥淸Female] bears that breed this spring have what鈥檚 called delayed implementation,鈥� says Toom. 鈥淭heir eggs don鈥檛 become viable until the fall when their bodies have determined whether or not they鈥檝e consumed enough calories during pregnancy.鈥�
In other words, given just natural food sources nature will take care of itself.
