Bounty hunters keep invasive species in check

At least for now another successful case where the Public are invited to join the force to control invasive species, reported Nature. 

Another successful example I saw recently was how community participation and adaptive management turned back the tide of American mink invasion in Scotland. 

Of course such a strategy does not always work, and the same article mentioned a couple of examples: pythons in Florida and red foxes in Australia.  The pythons proved tough to catch because they were hard to spot in the Florida brush, and the removal of 1/5 of Victoria red foxes ended up boosting the population because the survivors thrived when they had less competition. 

Here is a recent paper reviewing such public-involved harvest programs.
