The Morton Register of Arboreta is a comprehensive list and database of arboreta and public gardens that have a substantial focus on woody plants. The purpose of the Morton Register is to identify all of the organizations in the world that collect and display trees, shrubs, and other woody plants for the benefit of the public, science, and conservation. The Morton Register is a constantly growing database and any identified or named arboretum, or public garden with a significant focus on woody plants, may be listed.
The Morton Register of Arboreta should not be confused with arboreta that have been accredited through the ArbNet Arboretum Accreditation Program. ArbNet-accredited arboreta are highlighted in the Morton Register with the official ArbNet accreditation badge and a link to their dedicated profile web page. Organizations listed in the Morton Register are strongly encouraged to become accredited through the ArbNet Accreditation Program.
