Climate change and biological invasion are major threats to biodiversity, but their combined effects haverarely been quantified. The introduction of congeneric non-native species, in particular, can be especially problematic for native species due to...

Haiti is home to an incredible flora of around 5,000 documented plant species. Within these, over 210 endemic shrub and tree species have been identified. These plants have only one home in the world, and it is here. Many other species have small...

Botanical gardens have contributed to plant conservation through the maintenance of both living 20 and preserved plant specimens for decades. However, there is still a large gap in the literature 21 with regards to understanding the potential...

A policy document developed to balance the public garden mission of holding diverse horticultural collections with the conservation mission of preserving natural areas and the broader environment.

Indirect climate effects on tree fecundity that come through variation in size and growth
(climate-condition interactions) are not currently part of models used to predict future forests.
Trends in species abundances predicted from meta-...

This is a companion resource to a presentation given by Tim Boland, Polly Hill Arboretum, entitled The American Oaks: Diversity, Ecology, Identification as part of the "A Focus On Sustainability" Webinar Series. 

Changes in phenology induced by climate change occur across the globe with important
implications for ecosystem functioning and services, species performance and trophic
interactions. Much of the work on phenology, especially leaf out and...

This template was developed by curators stewarding Nationally Accredited Multisite CollectionsTM. It provides a standardized format and defined data fields for plant records inventories to facilitate coordinated activities among collaborating gardens....

This plant collections policy (this “Policy”) memorializes the development and management of the plant collections of the Garden which include living plants, seed collections, DNA samples, herbarium vouchers and tissue samples. Consistent with the...

Ten years ago the Royal Botanic Gardens Victoria embarked on an ambitious project to collect, treat and distribute storm water from the catchment within and around the botanic garden. The infrastructure of wetlands filtration, a sophisticated water ...

The contributions of crop wild relatives (CWR) to food security depend on their conservation and accessibility for use. The United States contains a diverse native flora of CWR, including those of
important cereal, fruit, nut, oil, pulse, root...

With digitization and data sharing initiatives underway over the last 15 years, an important need has been prioritizing specimens to digitize. Because duplicate specimens are shared among herbaria in exchange and gift programs, we investigated the...

Available to Members only.

Since the Ontario Cosmetic Pesticide Ban of 2009, Royal Botanical Gardens (RBG) had struggled to maintain its Rose Garden to world class standards. Ontario's 2017 sesquicentennial celebration afforded the perfect...

Plant and fungal specimens provide the auditable evidence that a particular organism
occurred at a particular place, and at a particular point in time, verifying past occurrence
and distribution. They also document the aspects of human...

The Neotropics are the most species-rich area of the planet. Understanding the origin and maintenance of this diversity is an important goal of ecology and evolutionary biology. Success in this endeavor relies heavily on the past work of taxonomists...

The United Nations' Sustainable Development Goal (SDG) 17 calls for “strong global partnerships and cooperation” to support the other SDGs. The collections-based science community offers many examples of conservation of plant and fungal biodiversity,...

The adoption of a Global Strategy for Plant Conservation (GSPC) in 2002 and its subsequent renewal in 2010 were significant milestones for the Convention on Biological Diversity. Not only did this strategy, its objectives and targets provide a valuable...

Extinction rates are expected to increase during the Anthropocene. Current extinction rates of plants and many animals remain unknown. This study represents the first effort to quantify extinctions among the vascular flora of North America north of...

This Research Topic aims to synthesize and inspire the frontier of integrative and translational research using herbarium collections to highlight their unharvested potential for addressing outstanding research questions and societal challenges. The...

Contemporary climate change is exposing plant populations to novel combinations of
temperatures, drought stress, and other abiotic and biotic conditions. These changes are
rapidly disrupting the evolutionary dynamics of plants. Despite...
