Mountain lions – also known as pumas, cougars, and even sometimes panthers – are the most widely distributed wild land mammal in the world. They are found from Canada to South America. There are an estimated 30,000 mountain lions in the United States, mostly in the West, but there are also mountain lions from the Midwest to the East Coast.

Unlike wolves or grizzly bears, mountain lions are not managed by the federal government; they are managed by states and state regulations vary greatly. In some places, hunting mountain lions is banned completely; in other places, it is always open season.

As more people encroach on wild land – building homes and small farms, as well as hiking and biking – the numbers of encounters between people and mountain lions are increasing. And when mountain lions lose their fear of people, there is trouble.

Since 1890, there have been at least 32 fatal mountain lion attacks on humans and more than 170 non-fatal attacks. California has seen the most attacks in the last 40 years with 22 people injured and four killed. Despite this, Californians passed a ballot initiative in 1990 that bans all hunting of mountain lions.

There are strategies to reduce habituation and instill fear of humans in mountain lions. One is called “tree-and-free” that uses dogs to chase mountain lions up trees. But there are opponents of this and other measures employed.

The fact is that there are simply too many mountain lions living in close proximity to humans and peaceful coexistence is very difficult to achieve. Places where hunting lions is permitted have few problems with them, but that is not a solution that is acceptable in many places. It’s a difficult problem.

Deadly Encounter: Mountain Lion Attacks Spark Controversy

The increasing reduction of sea ice in the Arctic is changing the behavior of polar bears. Because they are spending more time on land, they are interacting with people much more frequently, occasionally with deadly results.

A study, published in 2017, looked at 144 years’ worth of polar bear attacks on humans in the Arctic. Between 1960 and 2009, there were a reported 47 attacks by polar bears on people – between 7 and 12 per decade. Between 2010 and 2014, as sea ice reached record lows, there were 15 attacks, a record for a four-year period. Since 2000, 88% of attacks have occurred between July and December, when sea ice is at its lowest level of the year.

Last July, a young male polar bear attacked and killed a man who was berry picking with his children. A month later, a mother polar bear attacked and killed an Inuit hunter and injured two others. This was the first known fatal attack by a mother polar bear.

As a result, Inuit communities in the Nunavut region are asking for higher legal polar bear harvest quotas, arguing that bear populations have increased to a dangerous level.

These recent human fatalities have also provided an impetus for developing new non-lethal conflict-resolution tools than can be used in northern communities before more people as well as bears are killed.

There are now polar bear patrol teams tasked with driving bears away from settlements. There is a bear hotline and electric fencing around sled dog compounds.

The changing face of the Arctic is creating growing stress on the polar bear population and on the people who make their home in that region.
