The UT Austin Environmental Science Institute (ESI) has a great Hot Science – Cool Talks series that brings scientists from UT Austin and across the country to talk about their neat science research. Kids of all ages are invited to attend.
Mr. Geoff Hensgen, ESI Outreach Coordinator, invited me to bring my Invasive Hunter Academy to their most recent event with Dr. Jay Famiglietti, “Last Call at the Oasis: Will There be Enough Water for the 21st Century?”
I was excited to, but I wanted to add more information for high school students, since I knew they enjoyed coming to the Hot Science presentations. So I researched about some of the water problems caused by invasive species.
Invasive Hunter Academy Grows
I really liked the new info that I added to the Invasive Hunter Academy. I still have the three fun original steps to becoming an invasive hunter:
- Know your enemy – Match up pictures of native and invasive plants
- Know your action moves – Practice the three cool taekwondo moves to take down invasive plants
- Create your action scene – Build a great diorama to take home
For Dr. Famiglietti’s Cool Talks event, I created a new presentation for young adults with some great information about my nemesis, the Giant Reed. I talked about:
(1) What invasive species are and specifically the problems of the Giant Reed (Arundo donax). I showed how easy it is to find sightings of the Giant Reed and other invasive species that citizen scientists reported around the state by using the Texas Invasives database.
(2) The EPA is considering using the Giant Reed for biofuel because it grows fast and doesn’t impact the food industry. That’s great for a biofuel plant, but the Giant Reed can easily escape into the native ecosystem and take over as an invasive species.
Scientists are concerned that the spread of the Giant Reed to could create an economic and environmental disaster, and for that reason it should not be used as a biofuel.
(3) Especially for Dr. Famiglietti’s freshwater talk, I added information about how the Giant Reed is a threat to the survival of the Rio Grande River because it:
- Reduces the available water supply
- Chokes waterways
- Inhibits with power generation
- Interferes with agricultural irrigation
- Degrades water quality
- Threatens the of health of native plants and animals by creating a dense monoculture and crowding out native plants
QR Codes Help Presentations Jump to the Web
I added QR codes to make it easier for people to access the websites that I talk about in my poster presentation. I first added QR codes when I brought the academy to the Wildflower Center as part of Nature Nights this summer.
I saw people use their iPhones and Android phones to scan the QR codes to access my website, so I wanted to add more codes for my Hot Science presentation to help bring people to where they could get more information on the web, like to learn more about the Giant Reed.
High School Students Graduate to the Academy
The audience was older than my other academy presentations. There were many students from eighth graders to high school and college students. That was neat!
I enjoy bringing the original academy activities to kids all ages, but now I especially enjoy talking to the older students and teaching them about invasive species. (In these pictures, I still have my hand in a cast from when it got broken during a taekwondo sparring match. :-()

They found my posters very helpful, because a lot of students were there with their science classes, and they had notebooks that they were writing in for extra credit. I talked with them about the problems with the Giant Reed, and they took copious notes. I hope they all got great grades! 🙂

They really liked my “I’m an invasive hunter'” stickers and went to my website on their phones to watch my videos too. They put the stickers on their shirts and books, and one of the high school freshman put it on his forehead. (Not recommended.)
Battles with Invasive Species Videos

Mr. Hensgen is just the best! I want to thank him for inviting me to be part of the prelecture fun and the interview with Dr. Famiglietti. He gave me the best table because it was near the entrance to the auditorium, and he gave me a projector to play my Battles with Invasive Species videos on the wall during the event.
During the event, I played two videos:
- Invasive Hunter Academy – Although I filmed this one to preview my Washington DC presentation at the U.S. Botanic Garden, it still provides a great introduction to the Giant Reed and to the original Academy events. I also look great in a taekwondo uniform. 🙂
- Native Plant Avengers – This is one of my more recent videos (and was part of the great Lights Camera Help film festival). It also brought a lot of color to the video with the yellow Bastard Cabbage, an invasive plant that the native Texas wildflowers were battling.
One Freshman high school girl came back another time for two reasons: she was interested to learn more about invasive species and she had also left her iPod. 🙂
It was also great to talk again with Dr. Jay Banner, Director of the UT Austin Environmental Science Institute. I saw him being filmed for the Longhorn Network during the event. Thanks, Dr. Banner, for mentioning me during your prelecture slides!
Last Call at the Oasis
I also had a great time chatting with Dr. Famiglietti before his talk. I wished him good luck, but he didn’t need it because he did a great job!
I found one of the reserved chairs in the auditorium. (Thanks Mr. Hensgen!) and I noticed that they were much, much more comfortable than the regular chairs. (They were the same as the other chairs, but since they were reserved, they were extra comfy!)
Dr. Famiglietti talked about the making of his video, Last Call at the Oasis. It was released on DVD on November 8th, so be sure to check it out!
At the end of his talk, he showed a funny video with Jack Black about their drinkable, treated sewage water, porcelain springs.
Learn More about Invasive Species
My thanks to Ms. Jessica Strickland for all her help teaching me more about invasive species on the Texas Invasives website and at SXSW Eco. (I learned about the EPA considering to use the Giant Reed as biofuel from the Texas Invasives iWire newsletter. If you don’t already receive this monthly email newsletter, be sure to subscribe to iWire today.) I also learned about the Rio Grande River’s problem with the Giant Reed from presentations during the 2011 Texas Invasive Plant and Pest Conference.
I also want to thank Ms. Alice Nance, Lady Bird Johnson Wildflower Center Education Manager. She gave me a lot of goodies to pass out during the prelecture fun. I had Wildflower Center brochures with discount coupons and Plant Hero badges and certificates. (Kids had a lot of fun with Plant Heroes too when I brought the Invasive Hunter Academy to Nature Nights at the Wildflower Center this summer.)
Next Hot Science – Cool Talks presentation
Thank you again Dr. Banner, Mr. Hensgen, and Dr. Famiglietti for everything! 🙂 If you missed the event, watch my video interview series with Dr. Famiglietti and check out the webcast replay of Dr Famiglietti’s presentation. (It was ESI’s 80th Hot Science – Cool Talks event!)
I had a fantastic time, and I can’t wait until the next Hot Science – Cool Talks event on November 30, “The War on Cancer: 41 Years after Nixon’s Declaration“, with Dr. Mark Clanton.
Hope to see you there!
Your friend,
Ben
