Below is the file that represents the complete BioBlitz data set, including the current species and observation lists for the 2025 Macaulay Honors College Brooklyn Bridge Park BioBlitz. This data set is compiled from observations we recorded using both our paper data sheets and iNaturalist.<\/p>\n\n\n\n
The first sheet in the file above is a summary page with our species count (currently at 499 species!<\/strong>), then there is a full species list compiled from our data sheets and confirmed iNaturalist observations (as of 10\/10\/25), a list of all data sheet observations (includes multiple observations of the same species), a list of all confirmed iNaturalist observations, and then the individual observation data sheets for each BioBlitz team.<\/p>\n\n\n\n On November 4, our bacterial diversity analysis from Dr. Theodore Muth (Brooklyn College) came in. There are still more analyses pending. Here is what he says about this data set: We collected 4 marine samples from the East River and 4 freshwater samples from the stream running through BBP. We extracted the total DNA, amplified the 16S regions for bacteria, and then Nanopore sequenced nearly full length 16S genes. We detected over 2320 genera. I ordered them on the Excel file by most abundant. Then I color coded the top 25 (pink = abundant in marine, scarce in freshwater, and green = abundant in freshwater, scarce in marine, and uncolored, present in both).<\/em><\/p>\n\n\n\n The iNaturalist data set itself will be more current if you download it directly from iNaturalist<\/span>, as the lists can change as more of the community leaves identifications. You can check out the iNaturalist observations at the project page<\/a> for this BioBlitz. There is a button on the right side to download a csv file of all of the observations. For step-by-step instructions on downloading iNaturalist data, check out our Data Download Guide<\/a>. As the iNaturalist community confirms more IDs, it is possible that the species number listed here will change.<\/p>\n\n\n\n Here is a sample of what you can download from iNaturalist (as downloaded on October 10, 2025) and a file that explains the columns:<\/p>\n\n\n\n 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 \u201cExport observations\u201d to the right of the screen (see the Data Download Guide mentioned above). We strongly recommend that people interested in using our species list data use the species list generated by students and scientists in the park during the BioBlitz and\/or the Research Grade observations from iNaturalist. A combination of those two sources of confirmed identifications can be found in the main BioBlitz results data file at the top. The full iNaturalist observation list contains MANY unconfirmed observations. The confirmed Research Grade ones have been extracted from that list and added to the main results file.<\/p>\n\n\n\n Brooklyn Bridge Park has an iNaturalist project to document all of the biodiversity of the park: https:\/\/www.inaturalist.org\/projects\/brooklyn-bridge-park-biodiversity<\/a>. Our 2106 Macaulay BioBlitz was at Brooklyn Bridge Park and you can find the results for that BioBlitz on this page: 2016 Brooklyn Bridge Park BioBlitz Data<\/a>. <\/p>\n\n\n\n The Data menu (left side panel) links you to all previous Macaulay BioBlitz data sets. Click here<\/a> to see all of those posts together. Please keep in mind that 2020 and 2021 were Remote BioBlitzes and the data were collected differently in those years (i.e. not in single park over a weekend).<\/p>\n\n\n\n The NYC arm of the global City Nature Challenge, a four-day city-wide public BioBlitz run entirely on iNaturalist, is organized out of Macaulay by Dr. Kelly O\u2019Donnell. The City Nature Challenge: NYC umbrella project<\/a> will link you to all years of previous CNC:NYC results. Download those data in the same way you would download iNaturalist data for the BioBlitz.<\/p>\n\n\n\n There also have been some non-Macaulay-affiliated BioBlitzes in NYC. Including:<\/p>\n\n\n\n For some historical biodiversity information, check out the Biodiversity Heritage Library<\/a>.<\/p>\n\n\n\n iNaturalist Research Grade records get uploaded into the Global Biodiversity Information Facility<\/a> (GBIF), an open access global repository for species occurrence data. Students and faculty can visit this site to search for relevant data. For example, NYBG uploads their digital herbarium records here. iDigBio<\/a> is another source for digital collections. For both of these, you can search for Van Cortlandt Park to find records.<\/p>\n\n\n\n <\/p>\n","protected":false},"excerpt":{"rendered":" Updates: Complete BioBlitz Data and Results Below is the file that represents the complete BioBlitz data set, including the current species and observation lists for the 2025 Macaulay…<\/p>\n","protected":false},"author":8,"featured_media":2487,"comment_status":"open","ping_status":"open","sticky":false,"template":"","format":"standard","meta":{"portfolio_post_id":0,"portfolio_citation":"","portfolio_annotation":"","openlab_post_visibility":"","footnotes":""},"categories":[25,11],"tags":[],"class_list":["post-2480","post","type-post","status-publish","format-standard","has-post-thumbnail","hentry","category-25","category-data"],"_links":{"self":[{"href":"https:\/\/openlab.macaulay.cuny.edu\/bioblitz\/wp-json\/wp\/v2\/posts\/2480","targetHints":{"allow":["GET"]}}],"collection":[{"href":"https:\/\/openlab.macaulay.cuny.edu\/bioblitz\/wp-json\/wp\/v2\/posts"}],"about":[{"href":"https:\/\/openlab.macaulay.cuny.edu\/bioblitz\/wp-json\/wp\/v2\/types\/post"}],"author":[{"embeddable":true,"href":"https:\/\/openlab.macaulay.cuny.edu\/bioblitz\/wp-json\/wp\/v2\/users\/8"}],"replies":[{"embeddable":true,"href":"https:\/\/openlab.macaulay.cuny.edu\/bioblitz\/wp-json\/wp\/v2\/comments?post=2480"}],"version-history":[{"count":10,"href":"https:\/\/openlab.macaulay.cuny.edu\/bioblitz\/wp-json\/wp\/v2\/posts\/2480\/revisions"}],"predecessor-version":[{"id":2580,"href":"https:\/\/openlab.macaulay.cuny.edu\/bioblitz\/wp-json\/wp\/v2\/posts\/2480\/revisions\/2580"}],"wp:featuredmedia":[{"embeddable":true,"href":"https:\/\/openlab.macaulay.cuny.edu\/bioblitz\/wp-json\/wp\/v2\/media\/2487"}],"wp:attachment":[{"href":"https:\/\/openlab.macaulay.cuny.edu\/bioblitz\/wp-json\/wp\/v2\/media?parent=2480"}],"wp:term":[{"taxonomy":"category","embeddable":true,"href":"https:\/\/openlab.macaulay.cuny.edu\/bioblitz\/wp-json\/wp\/v2\/categories?post=2480"},{"taxonomy":"post_tag","embeddable":true,"href":"https:\/\/openlab.macaulay.cuny.edu\/bioblitz\/wp-json\/wp\/v2\/tags?post=2480"}],"curies":[{"name":"wp","href":"https:\/\/api.w.org\/{rel}","templated":true}]}}iNaturalist Data from the 2025 BioBlitz<\/h2>\n\n\n\n
