We are calculating the conservation value, according to different goals, of four genera collections at The Morton Arboretum (lindens, crabapples, oaks, and elms), and developing plans to manage that value in the future.
We are quantifying how many individuals need to be kept in botanic garden collections to best preserve genetic variation, using case studies across the tree of life, including many threatened oak species, which will provide advice for future seed collections.
Living plant collections play an important role in conserving plant biodiversity. We collect and cultivate threatened tree species to learn about and safeguard important sources of tree genetic diversity.
Living plant collections play an important role in conserving plant biodiversity. We collect and cultivate threatened tree species, like Quercus oglethorpensis (Oglethorpe oak), to learn about and safeguard important sources of tree genetic diversity.
Bringing new, beautiful, and resilient tree and shrub varieties to market requires understanding how many sets of chromosomes species possess. This project explores the poorly understood genome size and ploidy of the genus Styrax (snowbells), a respected but uncommonly cultivated group of trees and shrubs.
The Morton Arboretum’s plant collections are recognized as one of the most significant collections of cold-hardy trees and shrubs worldwide. They are open to the public for study and exploration, and are frequently utilized for formal research projects and educational courses. This plan provides a strategic framework for collections development, with the goal of improving their diversity, maintenance, and visitor experience well into the Arboretum’s future.
A breeding population with genetic diversity is necessary for developing new plants with novel characters. Some plants can become weedy when introduced to a landscape, and reducing fertility can mitigate this effect.
