In 2003, the BBC reported that a population explosion of Great Gerbils had destroyed more than 4 million hectares of grasslands in China's north-western Xinjiang region -- an area about the size of Switzerland. By 2005 the damage covered 5 million hectares, and the Xinjuang Regional Headquarters for Controlling Locusts and Rodents were reported to be breeding and attracting pairs of golden eagles to curb the gerbil population. So McSweeney's Joshuah Bearman was assigned to the story. His report: An Investigation Into Xinjiang's Growing Swarm of Great Gerbils, Which May or May Not be Locked in a Death-Struggle With the Golden Eagle, With Important Parallels and/or Implications Regarding Koala Bears, The Pied Piper, Spongmonkeys, Cane Toads, Black Death, [and] Text-Messaging..
Screwworms, once the scourge of livestock (as well as pets and occasionally humans [link to VERY GRAPHIC slideshow]) throughout the Western Hemisphere, have been eradicated from the United States since 1966. In addition to constant vigilance by veterinary services and livestock handlers, who treated wounds immediately and set traps [link to 1920s informational film], the method which ultimately led to control of this horrifying pest is sterile insect technique. Maps showing the progress of the technique can be seen here. The USDA's National Agriculture Library maintains a special collection on the Screwworm Eradication Program. Here is a good overview of the problem and the USDA's solution, complete with (somewhat gruesome) pictures and videos. [more inside]
Open air sports stadiums often have issues with birds, insects, and other wildlife. Common preventative measures include ultrasonic devices and bird netting. But Nelson Mandela Bay Stadium - one of the venues for the 2010 World Cup - has taken an all-natural approach. It is working with the Urban Raptor Project to install raptors, bats, and owls to patrol the stadium for various pests, while a trained peregrine falcon chases away crows. This is not a new technique - Millennium Stadium in Wales has long used a Harris Hawk for bird control. But according to the NMB stadium manager, it "is the only stadium with a programme like this in place as a pest deterrent".
