GLOBAL PHOTO CONTEST, LIVE, SHOW US BIODIVERSITY THROUGH YOUR LENS with a collage of nature photos.

ISCN Photo Contest

The International Sustainable Campus Network (ISCN) is launching an extended edition of the “Biodiversity on Campus” Photo Contest, and we warmly invite members of the Harvard community to take part.

The contest highlights biodiversity measures and nature-positive moments on university campuses. Participants submit one photograph and a few details that bring the image to life: together, images and additional information form powerful, engaging narratives that help us think — and act — together for a resilient future.

Submit your photo by February 28, 2026.

Barking Up the Right Tree: A Tour of Bark Diversity at the Arboretum

Arnold Arboretum

What is there to see at the Arboretum after all of the leaves have fallen and before spring flowers start to bloom? Bark! Shaggy bark, mottled bark, striped bark: the Arboretum has it all. Join Horticulturist Rachel Lawlor to see some beautiful bark highlights, learn how to identify some trees by their bark, and learn why that bark looks the way it does.
