Field of Science

Hot, humid summer field work

Humidty on our prairie study site was about 300% (based on how it felt) this morning especially down in the vegetation where we had little seedling plots to photograph.  The emergent vegetation, e.g., compass plant, is already about 6 feet tall and getting ready to flower.  The grasses will wait until later to shoot upward for flowering.  Quite different from the stunted growth of last year's heat and drought.  This area has had rain for the past few days so the plants can transpire a lot, and that makes the humity down in the vegetation as high as it can get.  And as the morning wore on, the heat rose, and you just became soaked in sweat.  Now the only complaint here is that when you're trying to see things, bending over, you keep getting sweat on the lens of your glasses, and that's really annoying.  The other problem is the prairie vegetation has lots of rough edges, and wearing short sleeves for comfort, your arms get quite scratched from pawing through the leaves searching for your well marked plots that nonetheless are hard to find.  It's not just sedges that have edges.  In compensation it's a nice meadow of flowers this time of year, fleabane asters, yarrow, wild quinine (Parthenium integrifolium, shown with beetle floral
visitor), cone flowers purple and pale, pinks, black-eyed susans, sunflowers, lead plant.  Tomorrow morning will be a repeat.

Sounds lovely.

(you could always put a mini pad in the front of your hat to keep the sweat out of your eyes...if you're alone, or not a self conscious type) ;)
