What to observe

AntherColorLabeled

If you’re out walking in the woods this year, please consider taking data for the Trout Lily Project. There are a few trout lily species in Eastern North America, but this project is focused on American trout lily (Erythronium americanum). Below, you’ll find details on the data you’ll be asked to provide on the data submission website (detailed instructions on using the site)

Note: Sometimes, the color of the anther wall differs from the color of the powdery pollen within the anther.  Please focus your observations on the color of the anther walls (see F.A.Q.).

Date of observation: Record the date on which you observed trout lily.

Location information: Click on the map to indicate where your observations were conducted.  If you prefer, you can directly enter latitude & longitude data instead, but the data collection page only accepts these data in decimal-degree form.

Number of flowers observed: Roughly how many American trout lily (Erythronium americanum) flowers did you observe at the site? (< 50?  50-100? 100-250? 250-1000? >1000?)

Yellow anthers present?: Did any of the American trout lily (Erythronium americanum) flowers you observed have anthers of the pure-yellow color morph? (see photo below)

Red-orange anthers present?: Did any of the American trout lily (Erythronium americanum) flowers you observed have anthers of the red-orange color morph? Note that anything other than pure yellow falls into this category.  (see photo below)

PollenSpectrum_2017Edit

Estimated % yellow anthers: To the best of your ability, estimate the rough percentage of American trout lily flowers at the site with pure yellow anthers.  (By default, the remaining American trout lily flowers must have red-orange anthers).

Distance covered: Roughly what distance did you walk at the site? (<1km, 1–3 km, 3–5 km, >5km)

Photos (optional): If you’d like, you can share some of your trout lily photographs.

Observations can be submitted here.  See also detailed instructions for the CitSci.org site, and a summary of 2016 results.

  1. I will have to go back and look at pictures and if the rain ever stops the actual plants i have seen to determine anther colors. I assume for this project you are not looking at the white variety of Trout lilies that seem to be localized along the banks of the Grand River in Ontario just the yellow ones.
