What is the Black Rock Forest BioBlitz? 

Our project is a modest Bioblitz project, using the iNaturalist app, that allows Friends of Black Rock Forest to compare species diversity between the Forest and Central Park in NYC through fun citizen science while contributing to scientific data used globally.


How to participate in “Black Rock Forest BioBlitz” 


1- Form a team or participate solo!  

Join one of our guided hikes or pick a date and time to visit a green space of your choice and invite friends, family, or classmates if you wish.  


2- Create an iNaturalist account and join the Black Rock Forest BioBlitz  

You can join iNaturalist on a web browser or by downloading the app. iNaturalist has put together a very helpful Getting Started Guide.  

  • To join the project on the browser, search for the project “Black Rock Forest BioBlitz” under the community tab  

  • To join the project on the app, click on the more/menu icon, select projects, and search for the “Black Rock Forest BioBlitz” project.  

  • Direct links below to Black Rock Forest BioBlitz projects: 

We encourage you to practice with the app before you head out to your chosen area. You can use your cellular data to upload your observations as you take your photos, or you can upload them once you get back to a place with wifi. We have linked some useful resources at the bottom of this page.  

3- Head outside and take pictures of what you find 
  • Our interest is in wild organisms, so avoid taking pictures of humans and pets. If you believe a species was purposefully planted where you find it, mark it as captive/cultivated.  

  • You can decide to focus your observations on a specific set of organisms such as birds, flowers, trees, etc. or take pictures of the interesting organisms you spot on your outing.  

  • Try to take more than one picture of what you are observing. Ideally, you want a picture of the whole organism and a few close-up pictures of special characteristics that can help with identification.  

  • Remember to link your observations to the Black Rock Forest BioBlitz project!
