ArbNet: the International Community of Arboreta
ArbNet unites arboreta, botanic gardens with woody plant collections, and tree advocates around the world in a collaborative community dedicated to advancing the planting, study, and conservation of trees. Through its programs, shared resources, opportunities, and professional connections, ArbNet empowers institutions of all sizes to strengthen their collections, expand their impact, and contribute to global tree research and conservation efforts.
The ArbNet Arboretum Accreditation Program shares global standards for arboreta that celebrate institutions committed to the care and conservation of their tree collections. With four levels of accreditation, the program meets arboreta where they are—whether just beginning to grow or leading in research and conservation—while providing a pathway for continual advancement and international recognition. For more information on ArbNet programs and opportunities, visit www.arbnet.org.
Arboretum Research Partner List
The directory below contains ArbNet-accredited arboreta from around the world that have expressed interest in collaborating with researchers and conservationists in a variety of forms and scales. These partnerships could include project proposals and implementation; access to land, plant collections, plant material, and data; and/or connection with scientific expertise at these arboreta. While arboreta are centered around woody plant species, arboreta can offer a wealth of opportunity in many research areas, including:
- Horticulture / Arboriculture
- Ecology
- Biology
- Physiology
- Climate
- Genetics
- Systematics / Herbaria
- Soil science
- Pathology / pests
- Sustainability
- Wildlife science
- Aquatic science
- Behavioral and social science (e.g., audience engagement, learning impact, behavior change, etc.)
In some cases, the arboreta on this list are working towards advancing their ArbNet accreditation level, which would be facilitated through involvement with new research and conservation collaborations. Researchers can reach out to the contacts listed below with inquiries about how to organize research and conservation projects with individual arboreta.
Listings below include information such as location, types of research already conducted at location, flagship species, space availability, staff availability, collaboration information, and more.
This list is updated regularly as new arboreta apply to be included in this directory. If you wish to download the data or interact with the list, such as sorting and filtering, please click here.
