Van Aarde, R. J. (1984). Population biology and the control of feral cats on Marion Island. Acta Zoologica Fennica, 172, 107-110.
Predation by feral cats, Felis catus, on burrowing birds of southern temperate and sub-Antarctic islands has resulted in their presence being considered undesirable. Attempts to eradicate or control these cats on Marion Island, a temperate island to the southeast of South Africa, have included the introduction of the host-specific feline panleucopaenia virus during March 1977. Surveys suggest a continued decrease in population size since 1977, the mean cat density being 65% lower in June 1980 than in June 1976.

Since their introduction in 1949, feral cats have caused extensive damage to seabird populations on sub-Antarctic Marion Island, Indian Ocean. This paper reports on the first four years of an eradication programme launced in 1986. Eight hundred and seventy-two cats were shot dead and 80 trapped during 14 725 hours of hunting. Cats sighted per hour of night hunting and kills per hour decreased dramatically. Hunting success (cats killed as a proportion of those seen) decreased. The only reliable indication of the decrease in density as a result of hunting was the decrease in the number of cats seen per hour of night hunting. By the end of the third season it was apparent that hunting alone was no longer removing sufficient animals to maintain the population decline, and trapping was incorporated into the eradication programme.

I guess this is what happens when you put hunting into the hands of desk-jockies.
ReplyDeleteI managed to eradicate literally hundreds of these vermin from my lands, for miles around, in only 2 seasons, for less than the price of a couple cups of coffee (5000 rounds of .22s on close-out sale for $15. That's 3 cats per penny.)
I suggest you also select people who aren't trying to manipulate you out of your money too. "Hey Bob? How many cats did you shoot at today? 30? Get any? NO? Ah well, we can't be turning this into a cushy and well-paid NINETEEN YEAR CAREER FOR OURSELVES, now can we. LOL Those morons back at the office don't have even clue one. Pass me another beer -- ooops, there goes another cat! LOL...."
If you are plagued by criminally irresponsible cat-lickers (psychotic cat-advocates), following is a link with some of the most effective methods I invented to eradicate hundreds of these invasive vermin; by myself, on large tracts of land, in heavy brush and dense woods. The eradication so complete and effective that I've not seen even one cat in FOUR years now. (That "vacuum effect" cat-lickers cry about is TOTAL BS, it's based on the fact that cats attract cats, shoot and bury every last one and there's no cats there to attract more.) americanhunter D0T org SLASH blogs/arkansas-will-trap-feral-cats
Now here's someone who did even better than I did ...
"ONE landholder shot 460 feral cats in two days as the battle to stop them destroying native wildlife in North West Queensland ramps up."

Nice shootin'!
