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:

Recorded locations of the Giant Reed around Austin

(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:

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

Dr. Jay Famiglietti’s Last Call at the Oasis presentation at Hot Science – Cool Talks

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

Can Invasive Species Trigger Black Swan Events in Nature?

I’m looking forward to the upcoming Fall 2012 series of Hot Science – Cool Talks.

During the first presentation, Black Swans & the U.S. Future: Creating Sustainable & Resilient Societies, Dr. David W. Orr will talk about how sudden and unpredictable events drive change in human and natural systems.

I’m especially interested to learn if the introductions of invasive species to an ecosystem may represent black swan events in nature.

Deep Sea Invasion

I remember watching a rerun of the PBS Nova episode, Deep Sea Invasion, which showed how a bright green seaweed (Caulerpa taxifolia) that was used to decorate salt water aquariums escaped into the Mediterranean sea and created a choking monoculture wherever it went.

The dense carpet of seaweed represented a great change in the ecosystem since it overwhelmed native species and deprived native marine animals of food since the seaweed has a toxin that the creatures cannot eat.

In 2000, scientists found this invasive seaweed growing in the waters outside of San Diego, California, probably accidentally released by an aquarium owner, but due to early detection and rapid response, scientists were able to contain this killer alga with plastic and eradicate it with chlorine.

Like the Wakame (Undaria pinnatifida) seaweed shown in First wave of tsunami debris brings dock loaded with invasive species to the US West Coast, Caulerpa taxifolia is also in the Global Invasive Species database lists as one of the world’s 100 worst invasive species.

I can’t wait to attend the next Hot Science – Cool Talks and learn more about black swan events from Dr. Orr and the Environmental Science Institute at UT Austin.

Your friend,
Ben

Native Plant Avengers – Ecosystem’s Mightiest Heroes

Although hopelessly outnumbered by the invasive species Bastard Cabbage, Texas wildflowers assemble their combined strength to battle against the choking monoculture invading their ecosystem.

The loyal heroics of Texas Bluebonnet, the hulking presence of Bitterweed, and the lighting power of Indian Paintbrush bring their native plant diversity together in a desperate fight against their invasive foe.

Learn more about the vile invader Bastard Cabbage with these recent blog posts:

Bastard Cabbage Fouls Texas Bluebonnets

Commander Ben beseiged by Bastard Cabbage

What a nice surprise to see Dr. Damon Waitt on TV last night! Dr. Waitt is the Senior Director and Botanist at the Lady Bird Johnson Wildflower Center.

He was talking about Bastard Cabbage (Rapistrum rugosum), also known as Mediterranean Mustard. It’s a terrible invasive species that is overrunning Texas wildflowers, especially our beloved Texas Bluebonnets.

I first learned about Bastard Cabbage from him last fall in my video interview with him at the 2011 Texas Invasive Plant and Pest Conference. He said that this plant was the invasive species that really worried him.

Seeing Dr. Waitt interviewed by Mr. Jim Swift on KXAN reminded me of that plant, and I had to go out today to learn more about it.

Invasive Species Create Terrible Monocultures

Bastard Cabbage crowds out the wonderful Texas bluebonnets and creates a terrible monoculture. It towers over the bluebonnets, and the rosette at the base of the plant and long tap root steal resources that could have gone to the native Texas wildflowers.

They have a long stem and small yellow flowers. When I saw it when I was younger, I thought it was a native Texas wildflower.

Fight Back Against this Invasive Plant

In the KXAN article, Dr. Waitt said that with enough seed, Indian Blanket wildflowers might be able to compete with this invasive plant, but that’s a hard fight to win.

Bastard Cabbage overruns Texas Bluebonnets along highway 360 in Austin, Texas

Dr. Waitt said it’s best to hand pull Bastard Cabbage. I did my part pulling some up on highway 360 in Austin, and I took some down with my moves from the Invasive Hunter Academy. I also took a plant sample for my herbarium.

He said that on a 10 point worry scale, he’s at a 9.5. If Dr. Waitt’s worried about our Texas Bluebonnets, we should all be worried too!

Thanks, Dr. Waitt, and the Texas Invasives website for teaching me about this terrible invasive!

Your friend,
Commander Ben

Hydrilla and King Ranch Bluestem Create Devastating Monocultures on Water and Land

Ms. Mary Gilroy describes two invasive plants that have raided Texas waterways and prairies. Learn how Hydrilla (Hydrilla verticillata) creates massive monocultures in lakes and how King Ranch Bluestem (KR Bluestem – Bothriochloa ischaemum) outcompetes native vegetation in the Central Texas Hill Country. Ms. Gilroy is an environmental scientist in Austin, Texas.

This video is part of Commander Ben’s “Invasive Species: Secrets Revealed” series of interviews from the 2011 Texas Invasive Plant and Pest Conference.

Also, watch this YouTube video to see how the City of Austin and the Texas Parks and Wildlife Department have teamed up to release sterile grass carp to hunt down and munch away at Hydrilla on Lake Austin.
