The past couple of days were unique in that we were able to devote the majority of our activities to the educational aspect of the Henry’s Fork Foundation. On Friday, July 15th, we attended the Island Park Craft Fair at the Buffalo Run Campground where we set up a Henry’s Fork Foundation-sponsored craft tent for children. At the tent, children ranging in age from 4 to 12 were able to make and decorate their very own plant presses. The presses each consisted of two pieces of cardboard and newspaper bungeed inside of two pieces of painted plywood-like material to which the children added their own paintings and glitter. While the paint dried on the presses, Ann Marie took the children on a brief nature walk where they could locate their very own wildflowers to press and bring home. The presses ended up being a huge success! Many more children came than anticipated, but there were enough presses to go around and the children went home excited to go out into nature and find more plants to press.



Kids work away at designing individual hand-held flower presses.

On Saturday the 16th, we again set up a station at the craft fair. This time, however, we planned a very different sort of activity for the children: bug hunting. Prior to the fair, Anne Marie collected a bucket full of sediments and water from the Buffalo River and then divided it into smaller samples within petri dishes. The children who came to the tent were supplied with tweezers and microscopes so that they could pick out as many bugs from the samples as possible and put them in a separate water-filled container, from which Anne Marie taught them about what they were seeing. Stoneflies, Caddis cases, leeches, snails, and snail eggs were just some of the exciting critters which the children were able to discover and learn about in the context of their life cycles and their importance to river ecosystems.

Yesterday, Monday the 18th, Thomas and Eli spent the day cleaning and monitoring the Thurman Weir and Buffalo River fish traps. Meanwhile, myself and Heidi assisted Anne Marie in designing and going over some of the material for Trout in the Classroom as well as planning and improving an annual fieldtrip that local fifth graders make to the Chester Wetlands. The highlight of the day was definitely making a field trip of our own where we were able to meet with Josh Rydalch, the wildlife biologist working for Idaho Fish and Game at the wetlands. Josh took us on a brief hike of the wetlands which he thought could be added to the field trip program in order to enhance the children’s enjoyment and appreciation of the wetlands. From this little adventure, we were able to get an understanding of the diversity of plants, insects, birds, mammals, reptiles and amphibians which are found in the Chester Wetlands, thus enabling us to begin forming a vision of how to build upon the material discussed in the previous years to really emphasize the importance of the Chester Wetlands to the children. The next couple of months will consist of building upon these ideas so that the field trip could potentially take place this coming September, rather than when it ususally occurs in May. This change in timing would be ideal in that the weather will potentially be more enjoyable than in May and the children will hopefully also have a chance to view an endangered orchid which blooms in the wetlands around August/September of each year.

Barbed Wire and Calderas

This being my first post I'm not really sure how to start...so I'm just going to jump right in where Heidi left off. Last Thursday, July 7th, we interns spent our first full day off of the water in a long time to help out Kim Ragotzkie, the Stewardship Director at the foundation, with the very important task of fencing. After dealing with some unanticipated car problems first thing in the morning (aka attempting (and failing) to jump Anne Marie's car at the Shell station) we met Kim by the Mesa Falls exit off of Route 20 so that we could head over to Harriman State Park and begin working. And that's when the real fun began. Now when I heard that we were going to spend the day putting up barbed wire fencing I wasn't really sure how this task would stack up in comparison with our more regular duties; however, the day ended up being beautiful and fencing itself proved to be a task which gave us all a sense of accomplishment. By the end of the day we had replaced the fencing which had to be taken down for the winter (so as to prevent snow-induced damages) next to the portion of the Henry's Fork River running alongside of Route 20. While working with fencing is not something which we interns do all that often, ensuring that effective riparian fencing is in place is essential to the health of the Henry’s Fork in that it prevents cattle grazing from causing degradation to the riverbank. Thus, our day proved to be an extremely well spent break from our usual order of business.



After the weekend, we returned to work today for a field trip! Seriously though, who gets to go on field trips while at work…how awesome is that?! We were fortunate enough to spend the day with Dr. Bill Hackett, a local geologist, in order to learn about the unique geological history of Island Park and its surroundings. The highlights of the trip included stops at Mesa Falls, Big Springs, a location near the Island Park Reservoir, and various outcrops in the area primarily to discuss how the Henry’s Fork Caldera formed. We learned a lot of really technical stuff, but essentially continental drift along a hotspot, which is now in Yellowstone, combined with a series of volcanic activities roughly 2.1 million, 1.3 million, and 600 thousand years ago, are the things which have formed both the roughly 20-mile wide caldera in which Island Park lies as well as the neighboring caldera in Yellowstone. It was super interesting to be able to see Island Park from the perspective of a professional geologist, who looks at a landscape and sees things in a completely different way from most people. Today was truly a unique and informative experience for us interns to learn about this area where we are spending our summer.

Biocontrol, electrofishing, and feminine crawdads

Last Friday, Katie and I accompanied Kim around Harriman State Park to release bio-control flies. The flies were designed to control the Canada thistle that is invasive in the area. They had really pretty wings with a black and white striped pattern. We got to see new areas of the park and climb through sagebrush to place the flies on the thistle. Apparently the flies are a more efficient and cost-effective method of controlling the thistle and don’t involve putting chemicals in the park. They have been thoroughly tested and don’t attack the native thistle. It seemed like an ideal solution.

After a long Fourth of July weekend, we went to Thurman Creek to go electrofishing yesterday for the first time. All of the interns were there working, but it was definitely hard work! Two people were carrying the electrofishing equipment and shocking the fish while two others had nets to catch the fish and two more had buckets to carry the fish we caught. We were all learning how to do it (except Anne Marie, of course) so we had a couple more fish fatalities than we had hoped for. It was fun to see the number of fish swimming in the creek. We saw larger ones than we had seen before there. Because we were so new at electrofishing, we saw a couple big fish that we didn’t end up catching, but I am sure with practice we will get more efficient.

While we were waiting for everyone to get to the weir earlier in the day, Katie and I counted the fish and crawdads in the trap. The number of fish was much lower than it has been for the last few weeks, but the number of crawdads was huge. We counted more than 400 of them! We decided to try informally tracking the crawdads to see if they move much in the creek, so we took a random sample and painted them with coral colored nail polish on their shells. We don’t know if the nail polish will stay on or if tracking them will change anything, but it will make counting them in the future more fun.
