The Aquarium is currently open to the public. In response to COVID-19, we’ve made some essential changes to ensure a safe and enjoyable experience for all.
Get Nerdy with Nature
City Nature Challenge is an annual community science competition for cities across the globe to find and document the plants and wildlife found in urban areas. In light of the COVID-19 pandemic, the 2021 challenge is all about collaboration, not competition. It is an opportunity for participants to connect with other cities across the nation—and the globe—while exploring the nature found in and around their homes.
The 2021 challenge will take place in two parts: from April 30 to May 3, 2021, community scientists will observe wildlife and take photos of all the plants and animals they can find. From April 30 to May 9, 2021, the species documented will be identified. On May 10, 2021, the results will be announced!
As regional coordinator, the National Aquarium is committed to protecting, enhancing and restoring natural resources for the benefit of all people and wildlife throughout the Baltimore region. Part of that commitment includes knowing which species of wildlife live nearby and the types of habitats they need to thrive.

The National Aquarium is calling on community scientists to explore, identify and document urban wildlife in the Baltimore metropolitan area.
All observations made in the following counties and uploaded to iNaturalist during the challenge will automatically be counted towards Baltimore's City Nature Challenge totals: Baltimore City, Anne Arundel, Baltimore, Carroll, Harford, Howard and Queen Anne's Counties.

Thank You, Community Scientists!
Thanks to nature lovers like you, the Baltimore region had a tremendous showing in the 2020 City Nature Challenge! Collectively, as of December 2020, 705 of you made 11,087 observations, and identified 1,465 species in and around Baltimore—23 of which are protected, rare, threatened or endangered. This is the highest number of observations and species identified in Baltimore since we began participating in the challenge in 2018! Once again, the most commonly reported plant species in the area was garlic mustard, and the most commonly reported animal species was the northern cardinal.
In addition, 50% of Baltimore's verifiable observations (those with photo or audio evidence) obtained research-grade status, which means that this high-quality data will be shared with larger databases and used for research projects—helping science long after the challenge has ended.
Globally, 41,165 participants from 246 cities made 815,258 observations and recorded over 32,600 species—1,300 of which are rare, endangered or threatened.
