  • Growing Plants from Hardwood Cuttings

    Arnold Arboretum

    Hardwood cuttings are one of the many techniques the Arboretum uses to propagate its plants: propagators take cuttings from the mature stems of woody plants, carefully trim and coat the ends in rooting hormone, then plant them in specially designed growing media. Join Arboretum Propagator Sarah Shank for a hands-on workshop to learn this specialized form of propagation: the class will begin with a presentation on the biology of hardwood cuttings, then head outside to collect our own cuttings from nearby woody plants, and finally return inside to prepare and root the cuttings in growing media. Participants will bring home a small tray of cuttings to grow into their own small trees and shrubs.

  • Olmstead and the Arnold Arboretum

    Arnold Arboretum

    Frederick Law Olmsted, considered the father of landscape architecture, designed some 500 public spaces in North America. The Arnold Arboretum is the only arboretum he designed, a National Historic Landmark, and a model for others around the world. Docent Bill Beizer, will identify the elements of the Arboretum that best reflect Olmsted’s philosophy and approach to landscape design.

  • 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.

    New Perspectives in Ornithology

    Geological Lecture Hall 24 Oxford Street, Cambridge, MA, United States

    Ornithology—the science of birds—is experiencing a renaissance. Today, a new generation of tools is transforming how we study birds—from global citizen-science platforms such as eBird to satellite remote sensing and drone-based fieldwork. New Perspectives in Ornithology: 21st Century Dispatches across the World of Birds (Oxford University Press, 2026) reveals how these technologies are reshaping our understanding of bird life and the challenges birds face in a rapidly changing world. Volume editors Scott Edwards and Michael Reed will introduce the book’s key themes including bird ecology, evolution, behavior, citizen science, and conservation. Book contributors Jingmai O’Connor and Elizabeth Derryberry will then address how fossils are enhancing our understanding of bird evolution and how novel studies of bird songs are providing insights into how birds communicate and respond to environmental change.
