A citizen science project


What is Craywatch?

crayfish_prohibited_sign (42K)

Craywatch is a citizen science project to monitor the spread of invasive crayfish in North America. You can help science and conservation biology by participating in Craywatch projects.

  • North America has more crayfish species than anywhere else in the world. Large new species are still being discovered!
  • Almost half of North American crayfish species are a conservation concern.
  • Invasive crayfish are spreading through many regions of North America, threatening native crayfish through competition and disrupting ecosystems.

What will I need?

Craywatch projects are intended to use devices and online tools you probably already have! To participate in some of the first Craywatch projects, you will need:

  • A camera capable of getting close-up pictures; a good macro setting will help. A smartphone camera will probably work.
  • A way to get your precise latitude and longitude, such as a GPS-enabled smartphone. If you do not have GPS, you can estimate your location using Google Earth.
  • A Flickr account to upload your tagged photos.
  • A Google account so that you can edit Google Documents. (If you have a Gmail account, you already have this.)

If you come across a crayfish in the wild, take a picture of it (top and bottom, as close as possible) and mark down your exact location, and date. It'll be a little more complicated than that, but not much!
