Invasive Species Radio Script

 Niko: Hey this is Niko coming to you from Brockport NY to bring you a special news story.

Niko: Many people don’t know about the controversial topic of invasive species.

Niko: Now for the people who don’t know what an invasive species is; it’s basically a species that has been introduced in a place separate from its natural habitat through humans.

Niko: Here in New York there is a legal penalty for chopping down an ash tree. But why is that?

Niko: That’s because the Ash Borer Beetle, originally from Asia has found its new home here in North America. The beetles eat the trees and continue to do so since there are NO NATURAL PREDATORS in North America.

Niko: After speaking to Chelsea Major, studying biology at the University of Guelph, she had some things to say.

Niko: According to Chelsea, Borer Beetles only feed on trees that are already stressed. More and more trees each year are becoming stressed due to the climate change, making global warming a strong augment to this process.

Niko: Now, there is some theory as to how the Ash Borer came to this country.

Niko: Some think that the ash wood used in shipping imports and exports between the US and Asia could have been the vessel that the beetles used to travel here.

Niko: Although not confirmed, it seems like the most likely scenario of what happened.

Niko: With the migration of the Ash Borer Beetle, and the amount of trouble it’s causing, has caused resource managers come together to try and figure out a way to fix this problem.

Niko: Firstly, completely removing the beetles from the area is virtually impossible, and instead there have been motions towards controlling and preventing the spread of the beetles.

Niko: This means burning infested trees and injecting the trees with strong chemicals. Both these methods are pointless as the chemicals and burning don’t prevent new beetles from showing up.

Niko: The only hope we have, again coming straight from Chelsea, is to introduce a new predatory animal that will hunt the Ash Borer exclusively and help reduce their numbers.

Niko: Removing the Ash Borer will help save the ash trees. To find out more go to

Niko: That concludes our news-podcast, have a good night!



Great newscast!
You provided very information on the emerald ash borer and how it came to be an invasive species. I had learned about the species in my classes, but had never learned about it in such great depth. It was great to have such extensive background information on the topic.

One thing of concern is that you mentioned that invasive species are a controversial topic in the start. This was not really argued about further in the newscast. In what ways are invasive species controversial and are there multiple view points on the topic?

Keep up the great work!

Interesting topic as the amount of ash trees in Ontario has depleted greatly. Interesting to note is that most municipalities have an action plan in place, even as the populations of ash trees are depleted to almost nothing. The city of Cornwall Ontario has an excellent plan in place that can be viewed here:

As a farmer from southern Ontario, more specifically Oxford County, we too have had major bylaws put in place to handle all invasive species and different problems. I have noticed there are more and more consequences by cutting trees down on my farm, therefore it has become a common practice for me to go about the proper procedure of following all the rules put forth by our municipality. You can see our rules and regulations here:

Fantastic News Cast Niko, I was intrigued by this article because I realize how serious of a threat invasive species can be to ecosystems. Since our class has such a large emphasis on resource management, it is interesting to discover problems that may arise due to transporting raw materials between countries in an incredibly globalized world. The presence of the Ash Borer also posses challenges to resource management since a large industry such as timber, is now being threatened. The solution that Chelsea proposes regarding introducing a new predatory species is very intriguing and seems entirely plausible, but that might lead to more externalities related to introducing another invasive species to compete with other. I believe that adaptive management could be a good method to finding a solution to the Ash Borer. Adaptive management is where action is taken immediately to try and create a solution to a problem, even if they are uncertain whether or not their solution will work. By using this method, we would be able to see how a new predator might adapt to its new environment, but more importantly, action will be taken instead of waiting to come up with a solution in a laboratory. Do you believe adaptive management could work to resolve this problem?
