How climate change could lead bears to more human interactions

In the High Sierra, a bear encounter is expected. But there is reportedly much hope in more of Northern California this year. According to ethical experts, there are two main reasons why this can happen and both are related to factors that drive the instinct of bears. “Hibernation is a response to food shortages,” said Heather Johnson, a veterinarian with the USGS Alaska Science Center. When the main source of food for bea – think berries, nuts and insects – becomes scarce, bears know it’s time to rest and store calories. But as the human region becomes more and more integrated with the bear zone, bears are learning that human food sources may be high in calories. ”Said Johnson. And if the rats do not sleep, the best chance a human being can see is one, especially if the rat relies on human food, some years, natural phenomena can lead to a lack of natural food. the cold summer that kills the plants they feed on, last March was generally mild and dry, leading to the return of many species of plants. and freezing of the mountains.Bears are also highly sensitive to temperatures and will change their temperature depending on the unusually warm or cold weather. cording to Johnson, depending on latitude, height, weather conditions and the individual bear, can hibernate anywhere from 3.5 to 7.5 months. But as climate nudges the average temperature of each season above the bears, bears may eventually follow a shorter hibernation. Schedule. “What we do know is that when we saw these years where you had these warm winters, warm falls, we saw a really different attitude of bears,” Johnson said. character behavior. This can be clever given the unseen environment. “Bears see danger with contact with humans. They actually like to distance themselves,” Johnson said. any possible food source is preserved. This includes collecting and storing whole fruit from trees and locking animals, wild birds or animal feed.

In the High Sierra, encountered a bear is expected.

But many bears are seen reported in more cities Northern California weather this year.

According to ethical experts, there are two main reasons why this can happen and both are related to factors that drive the instinct of bears.

“Hibernation is a response to food shortages,” said Heather Johnson, a veterinarian with the USGS Alaska Science Center.

When the main source of food for bea – think berries, nuts and insects – becomes scarce, bears know it’s time to rest and store calories.

But as the human region increasingly interacts with the bears region, bears are learning that human food sources can be a good source of calories.

“Bears that have access to more food, whether it’s natural food or human food will slow them down and just keep eating,” Johnson said.

And the more the rats are asleep, the better human chances of seeing one, especially if the bear is dependent on human food.

In some years, natural phenomena may contribute to the natural deficiency of bears. One example is the late spring frosts that kill the weeds that eat them.

This past March it was generally very soft and very dry, resulting in the return of many species of plants. Then, in mid-April, cold snap brings frost in parts of the valley and freezes hard in the mountains.

Bears themselves are also very sensitive to temperatures and will change their cooling conditions based on unusually warm or cold conditions. This can lead to changes in sleep time from year to year.

According to Johnson, depending on latitude, altitude, weather conditions and the average person, they can hibernate anywhere from 3.5 to 7.5 months.

But as climate change raises the average temperature of any climate above that, the rats may follow a shorter vacation schedule.

“What we do know is that when we see these years where you have these cold, hot summers, we see the nature of different bears,” Johnson said.

Johnson said further research is needed to confirm any long-term conditions in the realm of hope. This can be difficult given the poor weather conditions.

“Bears see danger with meeting people. Naturally they want to be away,” Johnson said.

Johnson said the best thing a landlord can do to prevent hungry rats is to make sure all food sources are safe. This includes collecting and storing whole fruit from trees and locking animals, wild birds or animal feed.
