This phenomenon has biologist making conclusions that will focus on data related to extinction vortex issues. They already discovered a minimum density population (MDP) well beyond anything considered. It ranged from 9.2-13 lynx per 100 square kilometers. This Maine population may just save the entire species.
Having about 10 lynx per square kilometer is appreciable to Canadian based dens and residents zone and is startling for a US population, unlike those in the Northwest and Colorado. This may also represent a long loving natural residency in Maine for the Canadian lynx.
This brings us to the recovery outline where core areas were suggested to have 1 lynx per 100 square kilometers. New data suggests a drastic change in recovery plan with moving the threatened lynx to endangered. If range is essential for Northeast Canada (Alaska) to Colorado Rockies area as research suggests, the lynx may be capable hunters and a predatory check for prey species (snowshoe hares). Genetic data from Canadian Journal of Zoology (2007) suggests the need for conservation throughout core and peripheral areas, with avg. male distance travel from den travel directly correlating to survival of kittens.
Conservation biologists believe we may be able to use extinction vortex factors. like inbreeding depressions, but the key factors may be environmental and demographic stochasticity, meaning variance or rate of unpredictable change. With the lynx per Canadian environments, it is clear that these are both low and ecologically specific.
In areas considered core for the US, the demographic stochasticity is much higher as it seems to have recently affected the core areas. The study from Canada involved a lot of sampling of these regions including introducing male Canadian lynx of Alaska to the region.
Many offspring were recorded and genetic testing suggested that previous data of survival rate for kittens increase with males traveling ability. Still, there is a direct correlation to the snowshoe hare. So a new approach to save the Canadian lynx suggests to attempt reforestation in core regions to provide a boost in snowshoe hare and then hopefully when the data comes in we can apply an adequate prey substitute or other genetic advantages as with the introduction of non-local members of the species.
With the data provided, let us recollect and form an outline of the history of Canadian lynx threatened status in the US.
- Since the 1970’s is came from proposed threatened species to 1994’s start of an outline draft.
- In 2005 the first recovery proposal outline was submitted to the federal government but it had poor outdated data and could not make any direct suggestion for recovery.
- The light came in 2000 in Maine, right under the board members noses.
- Now that radio collared and other tests have been conducted a change in at hand and many believe the lynx recovery needs to be address and upgraded to endanger.
