We invite you to be a contributor to our citizen science collaborative 
project! We aim to harness the power of online citizen science communities 
to better understand the geographic range of select species. Our first 
project starts with two buttercups. They are showy, will reach a broad 
audience, geographically speaking, and can usually be identified from 
photos. Ranunculus ficaria (syn. Ficaria verna) or Lesser Celandine, an 
invasive in North America, and Caltha palustris, also known as Marsh 
Marigold, have broad geographic ranges spanning multiple continents with 
considerable overlap, and to beginners, could be difficult to distinguish. 
Our primary goal is to compare the observations collected in this project 
with the known distribution of each species: early detection of invasive 
species is important for their management. In addition, we hope to better 
understand the abilities of crowd sourcing, while gathering some interesting 
information for analysis. 

Contributing is as easy as a walk around the neighborhood! Even if you don’t 
know your buttercups, the online community of naturalists will help with 
identification! You only need a camera or a smart phone to document what you 
find, the location where you found it, and an account with one of two 
citizen science data collection platforms. Currently, we are active on 
iNaturalist (www.inaturalist.org) and Project Noah (www.projectnoah). 
However, Project Noah limits contributions to a 300 mile radius of 
Arlington, VA. Both platforms have a data collection tool available for 
smart phones. On either site, you can find our profile, NatureServe, and our 
project/mission, “Distribution of Look-Alike Buttercups.”
