Here is the current species and observation lists for the 2019 Macaulay Honors College Green-Wood Cemetery Gowanus Canal BioBltiz: 2019 Green-Wood Gowanus BioBlitz Data 10_9_19.The first sheet is a summary page with our species count (currently at 498 species!) which is likely to increase as some of the insect teams send back their final reports. You will find unique species lists, a list of all observations (includes multiple observations of the same species), and then individual observation lists for each BioBlitz team.

You can check out the iNaturalist observations at this link: There is a button on the right side to download a csv file of all of the observations. As the iNaturalist community confirms more IDs, it is possible we will get additional species from this list. Research Grade (confirmed) iNaturalist observations (as of 10/9/19) have been added to the Excel file above.

Here is a sample of what you can download from iNaturalist (as downloaded on October 9, 2019): 2019 BioBlitz GWGC iNaturalist Data ALL OBSERVATIONS 10_9_19 v2 and a file that explains the columns:iNaturalist Observation File Help 2019. Remember that these observations are geotagged, so you can map them if you are interested. You can always download an updated list from iNaturalist by going to the project link and clicking on Observations and then “Export observations” to the right of the screen. We recommend only using Research Grade observations for your projects, as these have IDs confirmed by the iNaturalist community.

Pull down the Data menu above to find the results of our previous BioBlitzes. You may also be interested in the results from the City Nature Challenge (a multi-day self-guided city BioBlitz). 2017 Results:  2018 Results: 2019 Results:

A two-year wildlife survey was conducted at Green-Wood Cemetery recently and the results can be found in this document: Green-Wood WILDLIFE SURVEY FINAL DRAFT 5.2.19

Gowanus Canal Conservancy hosted two mini-blitzes using iNaturalist. You can see the results from 2017 here: and 2018 here: Note that the times and place boundaries might be slightly different from our BioBlitz.

We have also downloaded all digitized herbarium records for Brooklyn using NYBG’s C.V. Starr Virtual Herbarium. These represent almost 200 years of botanical documentation. Some records explicitly mention Green-Wood or Gowanus, but all have coordinates if you are interested in mapping the records to see what was found in our BioBlitz locations. Here is the Excel file sorted by date: NYBG_Brooklyn Herbarium Records

There also have been some non-Macaulay-affiliated BioBlitzes in the city. Including:

The 2007, 2009, and 2010 Jamaica Bay Wildlife Refuge BioBlitzes:

The 2016 Gateway National Park BioBlitz:

The 2015 Van Cortlandt Park BioBlitz:

The previous (2003) BioBlitzes in Central Park:
