Food, Cover and Water. Repeat--- Food, Cover and Water. That is the basis for all wildlife populations to survive and continue. Your (Everyone's) local fox population yearly densities (#'s per acre, per mile, per county etc.) were the highest about 8 weeks ago as the litters were being born. Now they (#'s) are slowly being reduced daily by the struggle to survive. That is Bio. 101..................... How do you keep that harvest # higher for for a fall/winter removal???? Kind of tough with so many factors playing against the "fox crop" but here is the way science looks at it. If you want the potential for more animals you need to focus on the one or more of those 3 parameters that is limiting your production. Assuming you can positively influence one or all 3 with what you have you then can fine tune your focus on reducing predators (removing coyotes) and possibly (I said possibly) limiting harvest. The best example is ----- If you want more pheasants you increase the the nesting COVER so more babes get born. Maybe you can or can't increase denning sites for the fox in your area (I'm talking county wide now not just the few farms most folks trap on)...... So -------------- you search for another "helpful" avenue (I am old enough to have bountied fox) to increase those #'s . An animal with the roaming instinct and range that a fox has (as shown through research) will have no trouble emigrating (out) of high pop. areas and immigrating (in) to areas of suitable/good HABITAT. The K factor (Carrying Capacity) will be solely dependent on that quality of F,C, and Water. But your yearly harvestable "Crop" will be based on the yearly environmental exposures. So K's and populations don't always jive. Those pop. #'s can be way above or below the K. Yearly fluctuations are bettered buffered by the Higher Quality of the K though....... Floods, droughts, winter stress, hail, diseases, predation, land use etc. all factor into that yearly "Crop".... Here in NE our fox will "pup" alongside highways, by cemeteries, edge of towns, golf courses etc. anywhere the coyotes don't like to hang out. We have a high enough badger population (the den makers) and food base to have a lot larger fox K and higher yearly pop. but the inter-specific competition with the coyote limits the actual yearly #'s. So when coyote prices go to 6.00 for a gorgeous fully prime North Dakota/Montana pale, and we get over-run with yotes, remember that competition thing if you want to "help" the fox #'s................... the mike
