Plants are essential for life on earth, they provide food, produce oxygen, and are very very pretty! Unfortunately some plants become a problem when they are taken out of their natural habitat and inserted in another. Invasive plants can become a problem when trying to have a healthy environment for native plants as they create a competition for nutrients, water, and space. Although there are many different species of plants that are invasive there are some that are more common than others, for example: Birds Foot Trefoil (Lotus corniculatus) and Sweet Clover (Melilotus officinalis) are pretty commonly found in common gardens and prairie remnants. Although Sweet Clover is very common, getting rid of it is fairly easy, you just have to wait for a rainy day and then, once the rain stops, the soil will be wet enough to just pull the plants out of the soil! The same cannot be said about Birds Foot Trefoil though, its extraction does share the same need of rain but the extraction requires the use of soil knives and very often while trying to take out the plant it will break leaving the taproot still intact. 

Although there are existing methods to get rid of invasive plants, most of them are inefficient and require specific weather conditions. I decided to make a direct comparison between two methods of getting rid of Bird’s Foot Trefoil: Extraction, and herbicide. I randomly chose 20 plants of Bird’s Foot Trefoil around Tower Road and randomly selected 10 of them to be pulled out and ten of them to be treated with Green Shoots’ Blue Foaming Agent, Glyphosate 41%, and water.

While extracting Bird’s Foot Trefoil I started a stopwatch to record how long it took me to extract every plant. I divided the plants into two groups: medium plants and small plants as the difference is quite noticeable. The average time to extract medium plants was a minute and a half, while the average time to extract small plants was a minute. The amount of time is quite minimal but after applying the herbicide in the other 10 plants the difference is more noticas it took me an average of 20 seconds to apply in each plant no matter the size. Unfortunately the bigger plants were extracted some weeks ago by our team and I was not able to include it in this trial. 

Using herbicide was more efficient as it took less time, it was fairly easy to use, and it can be used at any day and time as long as it’s not rainy.

Here are some pictures of the application of herbicide, the herbicide is quite hard to see but you can zoom in!

June 15th, 2025 Before lunch

This morning we went out to ONTS, NICE, TOWER, GC, SGC to continue working on the capture, marking, and recapture of Agapostemon virescens (cute lil green bee). Although we tried our best the weather and the pollination state of the Echinaceas wasn’t the best, we were only able to see one new bee, and recapture one already marked bee. After the bees we came back to Hjelm to eat lunch, my sandwich was amazing! 🙂 

June 15th, 2025 After lunch

After lunch we split our team into three forces, Maddie S. and Gael (me) went out to outline Staffensons, Chelsea and Aaron went to finish decapitating Echinacea pallida ☠️, and Kyra, Maddie D. and Grace went to continue twist tying… or at least that was our plan IF IT WASN’T FOR THE RAIN! It started pouring outside and we had to run back to hjelm (more like drive but you get the idea) I was dripping wet. 🙁

The good thing was that thanks to the storm my car got all sparkly clean (at least from the outside) and we were able to finish counting the number of stipa seeds, so I would say we were very productive!

June 16th, 2025 (Today) Before lunch

This morning we went out to P01 and P08 to pull some sweet clover, it was the perfect weather for this activity, after the rain it’s always SOOOOO easy to pull it out (please don’t try to pull sweet clover when it’s dry, my hand still hurts a lil bit 🙁 ), and after that we all went to P01 to verify the stipa records. The morning activities were… wet, unfortunately I discovered a hole in the boots I was wearing and the fact that I was wearing jeans made everything more uncomfortable. 

June 16th, 2025 (Today) After lunch

After the wet morning we went back to Hjlem to eat lunch. My lunch was really good (thanks dad). After lunch we went back to the planned activities for the afternoon from yesterday. Maddie S. and Gael (me) went out to finish marking the perimeter at Staffensons, we had to walk A LOT but it was really cool to see so many prairie plants! After that we came back to Hjelm and the team was continuing twist tying, and I had time to work on my personal project (you’ll see what I mean in a couple days 😉 ).

That was it for today, keep checking the flog to see more of our shenanigans! Love you byeeee.

Today we went to the surrounding areas of P1 and P8 —Experimental Plot number 1 and Experimental Plot number 8 respectively— to take care of the weeds found in those places (birdsfoot trefoil aka Lotus corniculatus, and sweet clover aka Melilotus officinalis).

We know that invasive plants have been expanding around the remnants of prairie and that these invasive plants represent a risk for native prairie plants (Echinacea angustifolia, porcupine grass, little bluestem, big bluestem) as they compete for the remaining space and resources, but after trying for some time we have not found a herbicide that eliminates those weeds without damaging native prairie plants, therefore we choose to manually get rid of these weeds. We spent the whole morning getting rid of the invasive plants and we did enjoy it and it made us very happy to make plants happy. 🙂
