BROWN BEAR

Most people think that forest fire do more harm than more benefit to the brown bears but think again.Actually forest fire do benefit the brown bears
Fires that occur within remote wilderness portions of the grizzly bear recovery ecosystems, generally created a natural mosaic pattern of burned and unburned vegetation. Grizzly bears will benefit from increased diversity in the landscape and increased abundance of grizzly bear foods over time.

Survival of mammals in forest fire areas is in the upper 90% range. By creating many different food sources, these fires are beneficial to the grizzly bears. First of all, by burning away dense timber and smaller plants, it creates nutrients for future successional plants. In Montana , grizzly bear diets include huckleberries, which are successional plants. The fires also open up the canopy of trees in wilderness areas, allowing sunlight to filter in for smaller plants to be established. Some of these plants are also food sources for grizzly bears.



Grizzly bears often stay only a few hundred yards from a burning fire line. It has been observed that in these situations, they have appeared calm and unafraid of the fires. By staying close to the fire lines, bears are able to capture small prey running out of the burning forests. When the fires have subsided, grizzly bears re-enter the burn area, and obtain food sources from uncovered caches of pine nuts, homeless, small rodents, and those "barbecued" animals that were trapped by the fires. The overall long-term impact of fire is that it increases the diversity of habitats and maintains the resililience and vigor of ecosystems which is beneficial to grizzly bears

After the musk ox, the grizzly has the second slowest reproduction rate of all North American mammals, making it harder for it to rebound from threats to its survival. Females do not reach breeding maturity until they are 4 to 9 years old and generally give birth to two cubs every 3 years. On occasion, one or three cubs may be born to a female, but two is the more common number.So you see,we must stop killing brown bears or not we will never see them again...
