Stipa Search Round 2

Today the team conducted the second day of Stipa search. This time we came back to know points with Stipa plants using our visor and confirmed if a plant was present. The team learned how to differentiate basal Stipa plants from other grasses in the plot and confirmed the presence of many Stipa grasses that weren’t logged during our first day of Stipa search. In the afternoon the team worked on staking more BB points and collecting/setting up more emergence traps.


Demo Day #1

Today the team went out to Hegg Lake to flag flowering echinacea along with decapitating some pallida. We were joined by collaborators from NDSU who collected pallida samples for pollen and nectar studies. It was the first day of taking demographics of the echinacea this season. Taking the demographics went well and we estimated finding anywhere between 80 to 300 flowering echinacea pallida. Later in the afternoon the team split up to work on independent projects. Including, shooting bb points with the gps, working on proposals, and flagging more echinacea.

A Tale of Flora and Fauna

Today the team learned about Hesperostipa spartea (Stipa) which is affectionately known as porcupine grass. After reviewing the protocol for collection, we made our way down to experimental plot p01 where we received a lesson on identifying flowering Stipa and counting the fruits (imagine a long seed with a tail). We documented the number of culms (stems) and fruits as well as missing fruit in our field notes. This was only the first step but the information collected will help determine how the fitness – an organisms ability to survive and reproduce in an ecosystem – of Stipa grown in experimental plots differs from Stipa growing in prairie remnants.

Later that afternoon, a small team retrieved and deployed emergence traps. The contents of the traps were examined and the specimens were prepared for classification.

June 21st

Today was a busy Friday full of many activities! It is officially the first day of summer! Ning, Liam, and Maddie worked in P1 today fixing flags that might be out of place or not in line and also putting signs for positions so it is easier to know where you are. They also checked the flags in the 99 garden. Zach and Emma headed out to P8, where they watered the prairie turnips planted yesterday and planted extra plants. An interesting thing they noticed was that the prairie turnips seemed eaten across the first 3 rows. The team hypothesized that it might be hungry rodent. Ian helped Elise learn how to use the GPS and how to shoot some BB points. 

At lunch, the team had a discussion about their ABTs (And, But, So), which are goals for what each person wants to research or study further this year. There were many great ideas and lots of feedback in our discussion.

In the afternoon, Liam and Zach shot some more BB points. Ian, Maddie, Elise, and Emma and placed some more emergence traps!

Day in the Life

Today was a full day for team Echinacea! Not only is it Elise’s first day on the team, but it’s also summer solstice. This morning Brittany and I went out to Staffanson Prairie Preserve West to finish shooting bb-points. While another team started flagging/planting P8 for a new experiment. The new common garden experiment being added to P8 involves planting prairie turnip to learn how to grow and measure the species while establishing a basis for future studies.

This afternoon was busy finishing up planting in P8 while a handful of others went out and set the first emergence traps for the season! Woot woot!

Many more updates to come, along with daily posts from other members of the team.

first day of field season

Today begins the field season! We had many activities planned to get everyone off to a good start for a productive and learning-filled summer.

  • introductions
  • safety training
  • getting gear
  • visiting sites
  • lunch
  • mapping orientation
  • directed observations & flogging
  • scheduling rest of week

We wrapped up with watermelon and a group photo:

Observations at LCW and YOHW

  1. LCW- The study plot sits at the intersection of two roads, one of which is fairly busy. There were copious amounts of tall Brome grasses (cool season plant), and Lead plants (legume). These plants were observed throughout the study plot. There were also prairie roses lining about 5 feet of the roadside. We also observed one Echinacea angustifolia plant near the roadside. The study plot also contained trees and shrubs. It is suspected that this area was not involved in a recent burn. My group came to this conclusion based on the presence dried plant matter under the living plants. If there were a recent burn in this area, this would not be observed. There were not many flowering plants in this area. I hypothesize that it may be too early in the season or there is a lack of pollinators in the area.
  2. YOHW- The study plot is located in an area with less observed vehicle traffic. There were no tall grasses or dead plant matter. We observed very few identifiable plant species. I hypothesize that this area was burned in the spring. In conclusion, these sites were vastly different. We observed far more plant species at the LCW study plot likely because the area had not undergone a recent burn.

ALF West vs ALF East

For our first day we did direct observations with the goal of practicing your observational skills along with plant ID for our four plant groups of focus: C3 grasses, C4 grasses, legumes, and forbs. The group I was placed in looked at sites ALF East and ALF West. 

ALF West was our first stop. This site featured a fence line and natural hills that has been cut through by a gravel road. The site consisted mainly of C3 grasses. In the ditch and closer to the road we were able to see a handful of different legume and forb species, but the site lacked diversity in general. Due to this lack of diversity and over taking of C3 grasses the site appears to have not had a prescribed fire for a few years. Fortunately, we were able to see some emerging coneflower which is always exciting! 

ALF East was very different in diversity in comparison to ALF West. Based on visual observations diversity was a lot higher and most of the plant species found belonged in the legume and forb plant groups. With diversity being so much higher, and the plot featuring several plants that have appeared to have been scorched by fire it was our assumption that ALF West had experienced  prescribed fire in recent years. The landscape of ALF West not too visually different other than it featuring a corn field behind the prairie area unlike on ALF East. 

First day

Hello everybody,

My name is Liam Poitra and I am excited to be joing team echinacea for a second consecutive year. This summer I am hoping to deepen my knowledge further about the plant and animal interactions that make our prairies such dynamic ecosystems. For the first day with the whole team back, we spent the morning touring sites with Stuart and learning about common plants on the prairie. In the afternoon we worked as small groups setting out to remnants to familiarize ourselves the outcomes of burning on the prairie. Brittany, Ning, and I set out to observe 2 prairies 1 burned (yohw) and 1 unburned (loefflers corner). Yohw burned this spring was very short still all the plants were ankle height or lower and the soil was completely exposed without a thatch layer to cover it. However several plants showed great growth such as the heart shaped Alexander which seems to have already put out many leaves and was by far the plant to return the most vigorously at the site. Loefflers corner on the other hand showed plenty of brome and a thick thatch between plants. Both places seemed to have similar species however the forbs were easier to pick out at yohw

ALF West and ALF East Site Observations

Today we explored two prairie sites, one which had been burned recently and one which had not. It was startling to see the dramatic difference in the plants inhabiting each site, and the mosaicism that shows in the landscape of the burned site.

ALF West, the site that hadn’t been burned, was overwhelmingly dominated by non-native brome grass, while at the site that had burned, ALF East, we observed more diversity in grass species, as well as a very noticeable absence of the brome grass where it looked like the site had burned. We also noticed the impact of the fire on shrubs and trees in ALF East, and compared that to the new saplings coming up in ALF West. There were two Echinacea angustifolia plants that we observed in ALF West, growing in the gravel on the side of the road.
