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!

The best birthday gift anyone could ask for:

A smooth start to the first emergence trapping deployment! Today we placed 23 traps at three sites, making good use of our new color-coded flagging system. So cool to see our work from the last few weeks starting to pay off!

Some emergence trapping sites are a lot smaller than others! It will be interesting to see whether size is associated with catch rate. Do bees prefer to nest in big sites?
REU student Zach deploys a trap at our first site of the day. This site was burned earlier in the spring, can you see how short the vegetation is?

These traps will be out for four days, then emptied and sent back out to new sites on Monday. Fingers crossed we’ll see some bees!

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.

bad hawkweed

We have a patch of an invasive weed in our main experimental plot. We have been trying to keep this non-native hawkweed from spreading for several years. This year we did a really good job. First, we found all the satellite patches and used the opportunity to practice reading and making maps. Then we pulled all the flowers stems–we estimated 369 stems. Here’s a map of all hawkweed patches and the main infestations is the 10m x 10m square.

Then we pulled all the stems in the square of infestation, counting as we pulled. Here are the counts & the total in the square:

sum(172, 120, 165, 108, 142, 103, 128, 121, 206)
[1] 1265

After we counted and pulled, we each made an independent estimate of the number of flowering stems we missed. We could have missed stems that were trampled or difficult to see with the current light conditions. Here are our counts with the mean and median:

mean(37, 30, 25, 40, 120, 20, 40, 48, 32)
[1] 37
median(37, 30, 25, 40, 120, 20, 40, 48, 32)
[1] 37

Stuart went back when it was cloudy and found 47 stems in the infestation square, mostly trampled. The next day he systematically walked the square and found 4 more. So that’s 51 missed. One person had a pretty close estimate (48). All but one of our estimates were optimistic about our thoroughness.

round(c(37,51)/(1265+51), 3)
[1] 0.028 0.039

We estimated a miss rate of 3% and our actual rate was closer to 4%. We practiced estimating, pulled a lot of stems, ~1700, and have maps to go back and get the plants later this season. Good work, team!

I’m a junior in Environmental Science at Western Washington University, expecting to graduate winter quarter 2025.

Research Interests

I’m very interested the ecology of botany, mycology and soil. I’d be very interested in learning about how invasive species and fire ecology affect community structure of prairie ecosystems. 

Statement

I’m currently going to school in Bellingham, WA but I grew up in Eden Prairie, MN, glad to be back in the plains.

In my spare time I like to rock climb and kayak, birdwatch, forage mushrooms, read, and play banjo and guitar.

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:

First row: Ning, Hailey, Abby, Liam. 2nd row: Emma, Jared, Ian, Wyatt, Maddie, Brittany. Not pictured: Zach & Elise will start next week because their schools run late. Ruth will come up Thursday or Friday. Stuart took the 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
