Staffanson demap update

For the remnants, I finished data reconciliation for all the plants at Staffanson Prairie Preserve (spp) through 2021 in demap, our repository for data from the remnants. Each summer, we use the GPS to record the positions of every flowering Echinacea angustifolia plant within the transect at Staffanson, and we also revisit plants that flowered previously to check whether they are still alive, a process called total demo. This winter, I connected records between years so we can track the life of individual plants across the years.

Last week, I completed demo.out for Staffanson in 2017, 2018, 2019, 2020, and 2021. Demo.out makes one record for each plant that we visited each year and records whether it was living or dead, whether it flowered, and how many heads it had. This is the dataset that we can use to do longitudinal data analysis and study the demography of Echinacea plants over time. In 2020, both sides of Staffanson burned, and it had the highest flowering rate in the past 5 years – 275 plants! Of those plants, 33 flowered for the first time. In 2021, there was just one new flowering plant.
