Program line-up for 2015

This season’s programming features great speakers and many workshops, tours, and classes. Many talks will focus on tree conservation and seeds. Ned Friedman, director of the Arnold Arboretum kicks off our summer lecture series in early June with his talk on the evolution of trees. Author Richard Horan takes us on his journey of seed collecting at famous authors homes, Peter Crane delved in to the history of the ginkgo tree, and Quarry Hill director Bill McNamara shared his plant collecting adventures to save endangered trees around the world. Our own Tim Boland, Ian Jochems, and Tom Clark will share stories of their respective trips to the Ozarks and the American Southeast in search of endangered tree seeds as well.

Vanishing ActsVanishing_Acts_panels_MED

March – June 2015

Vanishing Acts, a traveling outdoor exhibit developed by the Morton Arboretum, is here! This exhibit seeks to increase public awareness of the precarious future of the world’s endangered trees. As the forests go, so go the trees. Experts are delivering new warnings that deforestation, plant diseases pests, and climate change are combining to dramatically reduce the amount and health of the world’s forests and trees. Ten percent of all tree species are now threatened with extinction, officials say.
Visitors will embark upon a global journey, exploring compelling tree stores from around the world displayed on 15 panels. Many of the featured trees are planted on the Arboretum grounds.ccouncil logo

Drawing from direct connection with nature, Permaculture gives us a set of principles and patterns for designing homes, businesses, and gardens that increase the health of the local ecosystem and move us beyond sustainability toward regeneration. Please join permaculturist Sean Walsh for this introductory presentation on the abundant world of permaculture design ‐ from basic edible landscaping to specific fruits, berries, vegetables, and flowers that you can grow at your home.
