“\u200aI’m gonna show you the power of iNaturalist,” he said, with the glee of a kid sharing a favorite toy.<\/p>\n

\u200aiNaturalist<\/a> is a smartphone app that identifies and logs nature \u2014 from botany to insects, sea life and birds.<\/p>\n

It’s pretty simple: Snap a photo of a plant or critter, upload it to iNaturalist, and it instantly suggests an ID. It’s almost like Pok\u00e9mon GO but for science.<\/p>\n

Then, once the photo is uploaded, experts and scientists weigh in and verify your findings.<\/p>\n

The rise of iNaturalist \u2014 and the community scientists using it \u2014 means a vastly expanded data set for scientists.<\/p>\n

As an example, Rebman pulls up a cactus with 59 official specimens mapped in the region. These are official museum specimens and, before the era of iNaturalist, this is the extent of the data scientists had to work with. Fifty-nine specimens is great, he said.<\/p>\n

But then he toggles his screen to also show iNaturalist observations. The map floods with dots \u2014 6,500 additional locations of this cactus in San Diego County.<\/p>\n

“That really changes our knowledge of what is where,” Rebman said. “It’s a crazy amount of data. So that’s why I do it, so that we better understand that diversity \u2014 where it is, and we can use that to better protect the species there.”<\/p>\n

Rebman is also rooting for San Diego to win this year’s worldwide City Nature Challenge.<\/p>\n

“We’ve always done OK as a community,” Rebman said of San Diego’s previous participation in the challenge. Then he added, conspiratorially: “I think we can do better.”<\/p>\n

\u200aTo join the Challenge, attend a guided hike or “bioblitz”<\/a> presented by SDNHM, San Diego State University Biodiversity Museum and the UC San Diego Natural Reserve System.<\/p>\n

Or just post your own photos as you explore the nature in your neighborhood. All wild plants and animals count, even non-native species. Join the City Nature Challenge 2026: San Diego County project<\/a> on iNaturalist to have your identifications contribute to San Diego’s hopeful victory.<\/p>\n

The challenge runs April 24 through 27.<\/p>\n","protected":false},"excerpt":{"rendered":"San Diego Natural History Museum botanist Jon Rebman points to his screen. “\u200aI’m gonna show you the power…\n","protected":false},"author":2,"featured_media":284948,"comment_status":"","ping_status":"","sticky":false,"template":"","format":"standard","meta":{"footnotes":""},"categories":[28],"tags":[74,76,75],"class_list":{"0":"post-284947","1":"post","2":"type-post","3":"status-publish","4":"format-standard","5":"has-post-thumbnail","7":"category-san-diego","8":"tag-san-diego","9":"tag-san-diego-headlines","10":"tag-san-diego-news"},"_links":{"self":[{"href":"https:\/\/www.newsbeep.com\/us-ca\/wp-json\/wp\/v2\/posts\/284947","targetHints":{"allow":["GET"]}}],"collection":[{"href":"https:\/\/www.newsbeep.com\/us-ca\/wp-json\/wp\/v2\/posts"}],"about":[{"href":"https:\/\/www.newsbeep.com\/us-ca\/wp-json\/wp\/v2\/types\/post"}],"author":[{"embeddable":true,"href":"https:\/\/www.newsbeep.com\/us-ca\/wp-json\/wp\/v2\/users\/2"}],"replies":[{"embeddable":true,"href":"https:\/\/www.newsbeep.com\/us-ca\/wp-json\/wp\/v2\/comments?post=284947"}],"version-history":[{"count":0,"href":"https:\/\/www.newsbeep.com\/us-ca\/wp-json\/wp\/v2\/posts\/284947\/revisions"}],"wp:featuredmedia":[{"embeddable":true,"href":"https:\/\/www.newsbeep.com\/us-ca\/wp-json\/wp\/v2\/media\/284948"}],"wp:attachment":[{"href":"https:\/\/www.newsbeep.com\/us-ca\/wp-json\/wp\/v2\/media?parent=284947"}],"wp:term":[{"taxonomy":"category","embeddable":true,"href":"https:\/\/www.newsbeep.com\/us-ca\/wp-json\/wp\/v2\/categories?post=284947"},{"taxonomy":"post_tag","embeddable":true,"href":"https:\/\/www.newsbeep.com\/us-ca\/wp-json\/wp\/v2\/tags?post=284947"}],"curies":[{"name":"wp","href":"https:\/\/api.w.org\/{rel}","templated":true}]}}
