Field monitoring of urban trees is essential to learn how urban forests change over time. Many arborists and urban forest managers worldwide seek to understand how their tree systems are faring in terms of growth, health, and mortality. The Urban Tree G

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.

Extinction rates are expected to increase during the Anthropocene. Current extinction rates of plants and many animals remain unknown.

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.

Contemporary climate change is exposing plant populations to novel combinations of
temperatures, drought stress, and other abiotic and biotic conditions. These changes are

As herbaria move to digitize their collections, the question remains of how to efficiently
digitize collections other than standard herbarium sheets, such as wood slide collections.

Botanic gardens and arboreta have evolved significantly from their origins as oases
reserved for the elite, to the conservation powerhouses they are today, visited by

Disease detection is one of many vital missions that biodiversity collections play, along with environmental assessment, online education, and detection of crop disease and potential bioterror
