Harvest the Invaders: Incentives to Control Invasive Species

September 8, 2014

Biologists Susan Pasko and Jason Goldberg discuss harvesting invaders in a new paper in Management of Biological Invasions. Incentive programs, such as bounties and encouraging recreational harvests, appear to be appropriate for certain species and regions. Among the many benefits is the development of an outreach program. “By engaging the public and encouraging harvest,” the authors write, “managers may . . . be able to identify where populations of invasive species are found and develop appropriate control and rapid response efforts.” The lottery program initiated by Maryland offered prizes to anglers who reported catching snakeheads, which assisted in assessing the spread of the invasive fish. No matter the species or the area, Goldberg insists that adaptive management–monitoring populations and program effectiveness–is key.

Commercial markets and incentive programs are likely to work when invasive populations are high, but once populations decline, the costs of harvest will increase. Efforts to reduce feral pigs in Australia showed that public interest in hunting declined with population size. Once a threshold is reached where the public no longer finds it profitable to harvest the species, traditional control measures and bounties may be more effective.

    I was unable to read the paper, the link was not working. Im very interested in harvesting the invaders for food, Asian carp especially. They are good to eat, so many of them, very widespread and cause harm to native species and the environment. I would love to make a living fishing and harvesting these Asian carp invaders, to make money feeding people and reducing the impact of an invasive species! How do I find a way to do this? I would love to work on a river and not in a warehouse.

    The link has been fixed. There are several start-up companies looking to harvest invaders, but there are no classified ads for harvesting invasives that I know about!

    Did the domestic ancestors of today’s feral pigs streak off De Soto’s ship into the Florida scrub of their own accord in 1539? Or did they have to be urged to go find something to eat? All you need to…
