Eating Invasives: Delicious or Dangerous?

  • 2 of 3

An upcoming paper by ecologist Martin Nunez and others to be published in Conservation Letters, the journal of the Society of Conservation Biology, encourages skepticism to this approach. In the paper, they argue that encouraging people to eat invasives may have unintended consequences. There’s a real risk, the authors argue, that people will start actually liking said invasives.

Entrepreneurs could develop markets for them; hunters could enjoy pursuing them. Invasives could become a part of the local culture. As a review in Conservation Magazine points out, native Hawaiians often oppose eradication measures for non-native pigs because pig hunting and eating is so clearly linked to their culture.

I can relate: On a recent weekend, my friends and organic gardeners Clay and Josie Erskine asked me to their farm to hunt the non-native (in Idaho) wild turkeys that had begun raiding their gardens. As we looked across their farm, ring-necked pheasants ran from the kale patch. Valley quail called from literally every corner of the property.

“Every one of them is a non-native species,” Josie sighed. “And they’re all absolutely devastating to vegetable farmers like us.”

Non-native quail, pheasants and turkeys have a constituency, though. Membership organizations advocate for their conservation. Landowners can receive government funding for practices that largely benefit these birds.

I reluctantly admit, as a non-native gamebird hunter, I would oppose any effort to eliminate these species.

Could campaigns to eat kudzu or camels or carp actually have the reverse effect? Could such campaigns lead to people protecting or spreading them?

It bears serious thought.

Here on Montserrat (Caribbean), we attended a workshop on the pros and cons of the Lion Fish, a purely invasive and poisonous fish currently destroying reefs up and down the east coast of the US and throughout the Caribbean.
They propagate at an enormous speed (5,000 eggs every three days). Their spines are poisonous. However, caught and handled carefully, they can be made into fantastic fish cakes. There were some made for all of us to taste. Now if only reps from the hotels and restaurants were at the workshop, and if only the fishers would stop throwing them back into the sea when the fish are trapped in their fish pots. Left alone, the Lion Fish are killing all the reef fish. The answer? Eat 'em!

Interesting points. Thanks.

Eating invasive non native species sounds intriguing. Saute Purple Loosestrife in unsalted butter perhaps? Pretty to look at but they chock off native plants in the wetlands. Sadly, I image the colourful loosestrife is likely not nutritious and maybe poisonous. Can be medicinal for sores according to medicinal lore but haven't seen it on the shelves. Even the wildlife in Canada won't eat it, except a few non native beetles.

No iguana's trek around as the cold in the winter would kill them off, dandelions and the like are tasty if not sprayed with toxins. Not everyone is a vegetarian, many are omnivores and while one says if we don't like invasive species then one can move, hardly workable. No pythons lurk here, too cold.

Some are areas of the world eat rats as meat...prices too high for regular meat. Ouch!

Meat eaters will always eat meat, others will stick to plant life. People do what suits their lifestyle. When Mother Nature redesigns life on Earth to consume rock pate and not living organisms be it plant or animals then we can dine on the non living and not judge the diet of others.

I love dandelion greens and agree that it is such a waste to destroy them with toxins. But you have to get permissions to harvest them and not all homeowners are going to let you onto their property.

Hi glaikit,

I loved the Gibnut story.

Heidi A. where on earth did you get the notion that Tilapia is a form of Carp??

Carp are various species of oily freshwater fish of the family Cyprinidae.

Tilapia is the common name for nearly a hundred species of cichlid fish from the tilapiine cichlid tribe.

Please note they are from different species completely.
