This summer, we harvested 330 Echinacea angustifolia heads from 23 prairie remnants. Remnant harvest started on August 16th and ended on September 14th, when we finally collected the last 4 heads, 3 at Steven’s Approach and 1 at Landfill West. We harvested the most heads on August 23rd, a total of 109 heads in one day. The heads are located in 15 gbags labeled RA-RP (there is no gbag RJ).
We only visited sites where we recorded phenology this summer, so we harvested from fewer sites than last year. We did not harvest from Aanenson, East Elk Lake Road, Near Town Hall, On 27, Riley, Railroad, or Town Hall.
After Manogya and I completed data entry on the harvest list, I inventoried all of the bags that we brought back to the lab. There were a few mysteries to solve. We had several extra heads, but they mostly turned out to be heads that were supposed to be harvested, but someone forgot to check them off on the harvest datasheet, so it looked like they were missing. However, there was one perplexing puzzle that took some sleuthing to unravel. Two different people claimed to have harvested a head with a black twist tie from plant 18066 at Landfill West. In the lab, I found two heads with black twist ties labeled 18066, but I knew that they couldn’t both be the same plant. I donned my Sherlock hat and examined all the available evidence: survey, demography, and phenology data. From the survey data, I figured out that plant 18066’s neighbor, plant 27711, also had a head with black twist tie, so one of the duplicate heads was likely from the nearby plant. The phenology data revealed that 27711’s head had white gunk on it during the summer, and it had more rows of achenes than 18066’s head. Sure enough, one of the heads was larger than the other and had a speck of white on it. Mystery solved! I removed the imposter from the bag of heads to clean.
The volunteers started cleaning the 2022 remnant heads on October 11th. They are currently working on gbag RE, bag 5 of 15, so they are making great progress.
