Description and Ecology

   Although this animal may look like another pet cat, just a bit bigger and fluffier, that your 7 year old self (or at least my 7 year old self) would just want to cuddle with on the couch at home, it is quite the opposite. Weighing in at 18-23 pounds, the Canada lynx (Image 1) is a medium-sized cat that measures to about 75-90 centimeters in length. The lynx call home to cold, snow covered forests and because of this have bodies that are adapted for that terrain. They have large feet that act as snow shoes to walk on the snow. They also have long legs, black-tipped tails and tufts on their ears that make hunting their prey in the snow easier. The primary prey of the lynx is the snowshoe hare. Since lynx population positivity is positively related to the density of snowshoe hare (refer to image 5) within its range they both inhabit similar areas, conifer and conifer-hardwood habitatsThese habitats have very cold and long winters and contain a combination of tree types including spruce,

Geographic and Population Changes

1       The Lynx required habitats range across different parts of the United States along with Canada and Alaska. The Lynx in the US are supported by the Boreal Forest. This forest is home to Canada but has southernmorst ranges in the Northeast, Great Lakes, Rockies and Cascade Mountains. The lynx has been recorded having appeared in the 14 US states that support the boreal forest. Some important findings by the FWS show that lynx populations in the U.S. are influenced by the lynx populations in Canada, some populations even having a direct connection. The FWS has also observed that some Canadian lynx populations are a source of emigration for lynx populations in the contiguous United States. Due to these findings, it is important to continue the connection between the contiguous United States and Canada to ensure long-term persistence of lynx populations in the United States.

Listing Date and Type

The Lynx was listed on March 24th, 2000 by the U.S. Fish and Wildlife Service. The Lynx is an endangered species and was categorized as "threatened".

Cause of Listing and Main Threats

The lynx are mainly threatened by timber harvest and recreation. The lack of guidance for conservation and forest management has allowed for timber harvest and fire suppression in habitats occupied by the lynx and their prey, the snowshoe hare, having a potential negative effect on the lynx. Legal trapping, hunting, and shooting of other animals such as bobcats, coyotes, and other furbearers in Canada is also a threat to the lynx. This is because it could lead to incidental trapping of lynx in Canada, effecting the rate of lynx that immigrate from Canada to the U.S. The high traffic volume on roads that divides one lynx habitat from another is known to be a threat to the lynx and the continued warming of the planet is a potential harm to the boreal forest ecosystem as well. 

                 
  Recovery Plan

The FWS constructed a plan for the lynx around the identified core areas and the protection of them. Specific objectives produced by the FWS include:

  • Retain adequate of sufficient quality to support the long-term persistence of lynx populations within each of the identified core areas.
  • Ensure that sufficient habitat is available to accommodate the long-term persistence of immigration and emigration between each core area and adjacent populations in Canada or secondary areas in the United States.
  • Ensure that habitat in secondary areas remians available for continued occupancy by lynx.
  • Ensure that threats have been addressed so that lynx populations will persist in the contiguous United States for at least the next 100 years. 
Recovery for the Lynx is considered achieved once conditions have been met that allow lynx populations to exist long-term within each identified core area.

  1. It was interesting to see that the main threat facing the Canada lynx is the harvest for timber. It was a good point for the recovery plan to acknowledge that the secondary habitat for the lynx remain available.

  3. I found it interesting that the range of the lynx extends so far into the United States. I hope that this species will be able to adapt to global climate change.

  4. I can understand how logging can severely affect a species. It's sad to see that the human demand for timber directly affects the decrease in the Canada Lynx populations.
