Smithsonian Environmental Research Center

Understanding Ecosystems for a Sustainable Future

As a public health precaution, the Smithsonian Environmental Research Center (SERC) is extending the cancelation or postponement of all public events, programs and gatherings until at least the end of the summer. The SERC campus remains temporarily closed to the public, including buildings, trails and other parts of the campus. Due to the rapidly changing nature of the situation, we are not announcing a reopening date at this time and will provide updates on our website.
