CPC Best Plant Conservation Practices to Support Species Survival in the Wild

These best practices represent a compilation of previous CPC guidelines with updated
recommendations from current research on rare plant conservation. Seed science is a rapidly growing field. To keep abreast of changes in technology and practice...

Using herbaria to study global environmental change

During the last centuries, humans have transformed global ecosystems. With their temporal
dimension,herbaria provide the otherwise scarce long-termdata crucial for trackingecological and
evolutionarychangesover thisperiodof intense global...

GloPL, a global data base on pollen limitation of plant reproduction

In a pollen supplementation experiment, fruit or seed production by flowers exposed to natural pollination is compared to that following hand pollination either by pollen supplementation (i.e. manual outcross pollen addition without bagging) or manual...

The history and impact of digitization and digital data mobilization on biodiversity research

The first two decades of the twenty-first century have seen a rapid rise in the mobilization of digital biodiversity data. This has thrust natural history museums into the forefront of biodiversity research, underscoring their central role in the...

Botanic gardens are an untapped resource for studying the functional ecology of tropical plants

Functional traits are increasingly used to understand the ecology of plants and to predict their responses to global changes. Unfortunately, trait data are unavailable for the majority of plant species. The lack of trait data is especially prevalent...

Ten-Year Performance of the United States National Elm Trial

Ulmus americana (American elm) was an important urban tree in North America prior to the introduction of the Dutch elm disease pathogen in 1930. Subsequently, urban and community forests were devastated by the loss of large canopies. Tree improvement...

Introduction to Access and Benefit-Sharing

Access and benefit-sharing (ABS) refers to the way in which genetic resources
may be accessed, and how the benefits that result from their use are shared
between the people or countries using the resources (users) and the people or...

Sustaining the Future of Plant Breeding: The Critical Role of the USDA-ARS National Plant Germplasm System

Plant breeders require genetic diversity to develop cultivars that are productive, nutritious,
tolerant of biotic and abiotic stresses, and make efficient use of water and fertilizer. The USDA-ARS National Plant Germplasm System (NPGS) is a...

Comparative Biology of Cycad Pollen, Seed and Tissue - A Plant Conservation Perspective

Cycads are the most endangered of plant groups based on IUCN Red List assessments; all are in Appendix I or II of CITES, about 40% are within biodiversity ‘hotspots,’ and the call for action to improve their protection is longstanding. We contend that...

Plant Exploration: Protocols for the Present, Concerns for the Future

Plant exploration provides the horticulture industry, public gardens, the scientific community, arboreta - and ultimately the public - with more diverse and hardier germplasm that increases the breadth of plants available for research and landscape use...

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...

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...

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...

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...

Experimental warming in the field delays phenology and reduces body mass, fat content and survival: Implications for the persistence of a pollinator under climate change

Temperature is universally important for organisms and the thermal environment of a diversity of organisms is changing rapidly because of global climate change. Warmer temperatures associated with climate change lead to earlier phenological events,...

Standards of Excellence in Plant Collections Management: Self-Assessment Tool

 A companion Self-Assessment Tool is now available to help you evaluate your organization’s current level of collections management. Use the results along with the...

Guidelines for collecting vouchers and tissues intended for genomic work (Smithsonian Institution): Botany Best Practices

This manual suggests standard practices that will insure the quality and preservation of the tissue and vouchers and their respective data. Although written for use by the Smithsonian Institution botanists it suggests a framework for collecting tissues...

The Role of Botanical Gardens in the Conservation of Cactaceae

Over 75% of all species of cacti are in decline, largely because of global environmental changes (GEC), including climate change. Mitigating the impacts of GEC on cacti will require a coordinated effort that combines conservation, research, and ...

Documenting Living Collections: A Study of Curatorial Practices, Challenges, and Solutions for Historic Botanic Gardens

Botanic gardens are living museums, offering opportunities for conservation and research as well as education, experience, and enjoyment through their plant collections. A garden’s plant records system is as vital as the plants themselves, and serves...
