LIVING COLLECTIONS POLICY U.S. NATIONAL ARBORETUM

The Living Collections of the USNA conserve plants and encourage their use for research, discovery, and education. The Living Collections also serve as an integral part of the collective botanical heritage of the public garden community. As a unique component of the USDA ARS National Plant Germplasm System (NPGS), the Living Collections are an international source of ornamental plant genetic resources. 

University of Delaware Botanic Gardens Collections Policy

The University of Delaware Botanic Garden, like any other botanic garden, is a repository of botanical collections that supports the mission statement of the institution (See Mission Statement). It is imperative that these collections be documented. UDBG has an official Collections Policy that should be followed at all times, (See Collections Policy). But what happens after a plant is brought into the garden following the Collections Policy? If the proper plant documentation is not recorded as soon as possible, this information is lost and the plant is no longer worthy of the collection.

The Arnold Arboretum Expedition Tool Kit

Being a plant collector for the Arnold Arboretum of Harvard University is a wonderful opportunity and privilege. Not only are collectors expected to engage in their activities in a professional manner, but they must meet the high Arboretum standards for plant sourcing and documentation. To equip collectors with the information vital to complete a successful expedition, this manual compiles knowledge and experience from plant collectors past and present, and includes references to necessary academic resources, checklists & templates, and physical materials.

The Protection of Indigenous Peoples’ Seed Rights during Ethnobotanical Research 

Recognition of the importance of biodiversity for global food security and the community food sustainability movement has helped increase awareness of seed rights. International treaties created to ensure the world’s access to seed biodiversity address access to seed banks for breeding purposes. Ethnobotanists are often required to deposit research plant specimens with government seed banks or herbariums. If Indigenous Peoples’ plants are then used developing patented varieties, are their rights recognized?

Priority Actions to Improve Provenance Decision-Making

Selecting the geographic origin—the provenance—of seed is a key decision in restoration. The last decade has seen a vigorous debate on whether to use local or nonlocal seed. The use of local seed has been the preferred approach because it is expected to maintain local adaptation and avoid deleterious population effects (e.g., maladaptation and outbreeding depression). However, the impacts of habitat fragmentation and climate change on plant populations have driven the debate on whether the local-is-best standard needs changing.

Species Recovery Manual

It is evident that species recovery is not well understood. It is a complex process involving many different disciplines and actors, and responsibility for it at a national level is often unclear, given that it cuts across different ministries and agencies. After various consultations, it was felt by BGCI and IABG that it would be valuable to produce a manual that would clarify the aims and purpose of species recovery, set out the various steps and processes involved, propose the necessary guidelines and indicate good practice.

Optimizing Conservation Strategies for a Threatened Tree Species: In Situ Conservation of White Ash (Fraxinus americana L.) Genetic Diversity through Insecticide Treatment

Forest resources face numerous threats that require costly management. Hence, there is an increasing need for data-informed strategies to guide conservation practices. The introduction of the emerald ash borer to North America has caused rapid declines in ash populations (Fraxinus spp. L.). Natural resource managers are faced with a choice of either allowing ash trees to die, risking forest degradation and reduced functional resilience, or investing in conserving trees to preserve ecosystem structure and standing genetic diversity.
