Measuring plants at Hegg Lake

Here’s a photo of the measurers and datatakers at the Hegg Lake common Garden on July 26th.
(L to R) Kneeling: Amy, Amy, Jennifer. Standing: Gretel, Ian, Andy, Ruth, Julie, Josh, Rachel, Colin, Jameson. Photo by Stuart–he measured too.

The weather for measuring turned out to be much nicer than predicted: Temp 85 degrees F; dewpoint: 70 degrees F; mostly cloudy with a W wind at 13 mph. It started raining, so we packed up to leave. As we were walking out the rain stopped, so we paused to take this photo. After the photo, it started to rain again.

We measured plants efficiently. Most plants have two leaves and the longest is 8-19 cm tall. It can be very difficult to find a plant because the thick grass is about 50 cm high. The only way to find it is to measure from another Echinacea plant. The ~4000 plants are spaced on 1m apart on a 80m x 50m grid. That can seem like a vast distance between plants. Jennifer made measuring sticks 2 meters long to help us stay on line and find the plants. After finding two plants you could keep on line fairly well and go fast. If there was a missing plant or a particularly sneaky plant, then it was very easy to get disoriented. Some folks worked in pairs (one measuring, one taking data); others solo. Here’s a photos of folks at work…
