Monday Movements

Today in Douglas County, Minnesota, Team Echinacea labored under a cloudless sky and oppressively high temperatures and humidity levels.

First thing in the morning, Sarah B. visited the remnants she is monitoring to study flowering phenology. Dayvis also departed to work on his own project, and was not seen again until 1pm. Today is the second day of flowering for Echinacea pallida at Hegg Lake, and Dayvis appeared elated to finally observe pollinators at work. Kory and Jennifer also went to Hegg Lake in the morning to visit Common Garden 2.

Those who did not have morning projects to attend to flagged and twist-tied flowering plants in the Common Garden. After lunch, the team departed to CG2 to measure plants. Throughout the day, Pam and Reina measured photosynthesis rates in the basal leaves of Echinacea in INB2. Marie and Reina also made/improvised pollinator exclusion cages. The technique for doing so remains unperfected.

Four plants are flowering in Andrea’s garden this year. Andrea Southgate planted this experiment (aka inb2) in 2006 as part of her Master’s research project. Andrea and Jennifer made a photo essay about their plantings that year. These are the first plants to flower in this experiment–about 4/1500 in their fifth growing season!

Common Garden Measuring 2009

Yesterday we finished measuring in the Common Garden! Here are some details about the protocol used for 2009:

Gardens: Inbreeding & INB2 we used the same form as in 2008. Basal and Flowering Rosettes were counted separately. Crisp leaves were included in the leaf counts.

Gardens: 2001, Monica’s, SPP, Big Batch, and 96-99 we used an abbreviated form. We did not record data on insect damage. Insects on all rosettes (basal and flowering) were recorded on the main form. Insects on the heads were recorded on the subform. Cauline leaves were not counted. The longest cauline leaf (longest leaf on the tallest flowering rosette) was recorded on the main form. For basal leaves, crisp leaves were included in leaf counts and also noted, as were leaves that were “gone.” Pips or duds with no florets were only recorded if there was a peduncle long enough for a twist-tie collar.

Staples 2009

Staples mark positions in the Common Garden where plants have died. Our policy has been to add a staple to a position where a plant has not been found for 3 years. This year, we’ve followed that protocol for the Inbreeding and INB2 gardens. However, we have added staples in Big Batch, 2001, SPP, Monica’s, 1996, 1997, 1998, 1999, and 1999s where plants have only been “Can’t Find” for TWO years. This should minimize the time it takes to search positions. We hope that plants and staples won’t both be found at the same position in the future.
