Mountain Rhodes and Coal Mines cut a grizway bear from the residence, study
A new study found that grizways beer had to change its movements in Canadian Rockies, which are more forced over time as they avoid human development such as coal mines, highways, large reservoirs and towns.
Posted in analysis of 20 years GPS collar data from over 100 grizzly beer, published in research, Conservation science and practiceIt was found that humans have made a significant impact on the way the bear moves forward in the 85,000 square kilometer scenario in Southern BC and Alberta.
Eric Palm, the lead writer of the study and a postdotoral researcher at Montana University, said, “The southern Canadian has already been quite a part of the connectivity loss for the Grizzly Bear in the Rocky Mountains.”
Any new coal mines, towns or highway roads create more obstacles to walk and find food for grizzly bears, he said – possibly large effects below the road.
“Since that base line is already very high, any additional damage can eventually have population-level effects for grizzly bears,” he said.
In January, province Picked a stay Opening the door for suspended projects to resume, on coal mining in eastern slopes of Rocky Mountains.
Palm stated that more human development on the horizon – like starting new and coal mines projects – can put bears’ houses further threatened.
“There are many proposed coal mines expansion of existing mines in BC and Alberta, and then there are some new mines that are being proposed,” he said.
“Construction of new coal mines in each of these areas … Human expands the footprint of infrastructure (which) can usually affect connectivity by disrupting animals going from a habitat patch to another.”
Search for food, find out trouble
Using computer simulation to estimate how more development will be affected in the future, the study found that those habitat patch would be more cut, the movement would be restricted.
Palm explained that the grizzly bears rarely come out in the priories in Canadian Rockies, which are limited to the mountains. But there, the bears are more constrained, because humans usually develop infrastructure in the bottles of the valley where some food sources thrive.
Researchers found that when the food was rare, both male and female bears are to search with the roads to search with the forest to get closer to the roads, such as homes for attractive foods such as grass, flowering plants and buffaloes.
A wildlife ecology and assistant professor at the University of British Columbia contributed to the study, stating that a “Grizzly bear who wants to live a long and happy life, needs to avoid humans as much as possible.”
The most recent count in Alberta shows 235 Deadly bear The periods between 2013 and 2022 were due to humans. The most known Grizzly bear in the province is due to humans.
In May, two women bear bears were killed By trains in separate events in Banff National Park.
“Sometimes humans are connected to where food is, but in general, we know that bears want to avoid being close to humans. They want to avoid being on the infrastructure used by humans,” said.
A potential threat to tolerating population
“If the gene is being stopped from flowing from one area … then eventually some of these populations may be more isolated than each other,” Palm estimated.
Although the study was limited within the scope of data of grizzly movements, Palm said that the new infrastructure was not only a place to research the ability to limit the dynamics of the bear, but also how their reproduction could be affected.
Although the threat of new development is concerned, Palm said that a lot of work is being done to help in increasing the habitat connectivity in Rocky, such as wildlife crossings or under roads that help animals move to human infrastructure.
“Now there is a lot of vulnerability between different species and how much they adopt using these crossings, and sometimes these crossings are very successful, and sometimes less,” said.
While wildlife crossings are still helpful in creating habitat connections, Avagar said, this solution is limited to roads.
“There are definitely situations where we cannot actually provide those crossing structures (eg) human settlements or a mine,” he said. “We cannot construct a bridge over it. This is an area that bears are going to escape to some extent.
“The main thing that we need to keep in mind is that when we plan development, we want to plan it on a large landscape scale, keeping in mind that we still allow the animal population to move to that scenario, and if we have blocked a path, maybe other paths for future development.
