This is the third lecture in the Arnold Arboretum's 2021 Director's Lecture Series. Tiya Miles takes up the pecan tree as inspiration for exploring the meaning of trees in the lives of enslaved African Americans. Using a family heirloom, slave narratives, oral histories, and missionary records, her talk underscores the importance of trees in the Black experience of captivity and resistance, ultimately revealing the centrality of the natural world to Black, and indeed human, survival.

At the time of its founding in 1872, the land on which the Arnold Arboretum of Harvard University is sighted was a patchwork of farmland and forest. As the Arboretum was planted, pathways were developed to lead people through the picturesque landscape. As the landscape developed, economies shifted, wars took place, and directors changed. Each of these factors subtly influenced shifts in the park’s path system. Join the Arnold Arboretum on Zoom with Jared Rubinstein as he reveals the layers of change in this beloved landscape.

A wanderer and writer with a doctorate in religion, Gavin Van Horn inhabits a big city. And that city (Chicago) has offered him something to compliment and complicate the solitude of the woods or a remote mountainside: a window onto the attractiveness of cities to animals. What was once in his mind essentially a nature-free zone turns out to be a bustling environment where millions of wild things roam. He came to realize that our own paths are crisscrossed by the tracks and flyways of black-crowned night herons, Cooper’s hawks, brown bats, coyotes, opossums, white-tailed deer, and many...

Urban and suburban planting spaces are often constrained, often not ideal for accommodating a large oak, linden, or maple tree. But there are many smaller tree species that will thrive in a smaller space and won’t overwhelm the area. Some trees are cultivars that have been selected for their smaller size or narrow characteristics, while others are naturally genetically petite. Guided by the “right plant, right place” philosophy, Laura Mele...
