Nature & Science

At BioBlitz 2016 300 people including 200 students made 285 observations of 116 species resulting in 10 updates to the park's species list. Thank you to all of our partners and volunteers.
In May 2016, the park partnered with The Nature Conservancy in Delaware (TNC) to host a public BioBlitz in the park at Beaver Valley. Located just a short distance from downtown Wilmington, Delaware, the Beaver Valley area of First State National Historical Park, is a treasure of winding nature trails along the the Brandywine Creek.

During the BioBlitz 300 visitors, including 200 students, used an app on their phones called iNaturalist to document 116 species through over 200 observations. In celebration of the one year anniversary of the BioBlitz we want to keep the ball rolling by encouraging everyone to become a Citizen Scientist. To get started, follow these simple steps listed below:
  • Select one of the following postcards: Butterflies & Moths, Caterpillars, Flowering Plants, or Biodiversity
  • Download and print your postcard
  • Download the iNaturalist application on your mobile device
  • Come visit us!
  • When ready, tap ‘Observe’
  • Add one or more photos as evidence (or upload photos from your camera later)
  • Enter what you saw—or what you think you saw. When and where you saw it should be added automatically. Save your observation.
  • Share what you find with friends on Facebook or Twitter through iNaturalist
  • Check off your observations and send the postcard to a friend!
*The postcards will be available to pick up at the Brandywine Creek Nature Center adjacent to Beaver Valley soon.
