The Association's TIPS Community presents a "Technology Tuesday" on the Association's PlantSnap Initiative featuring PlantSnap founder Eric Ralls. Find out how your garden can participate in this exciting citizen science project.

For more than two centuries, biodiversity collections have served as the foundation for scientific investigation of and education about life on Earth. The collections that have been assembled in
the past and continue to grow today are a...

Join Jenica Allen and Bethany Bradley to learn about new tools for identifying and prioritizing range-shifting invasive plants coming soon to a landscape near you. Whether you’re a property owner, land manager, landscape professional, or policymaker,...

Pollination is fundamentally important to ecosystem function and human food security.
Recent reports of dramatic insect declines, and pollinator decline in particular,
have increased public awareness and political motivation to act to...

Conifers are commonly planted in North America to provide year-round screening, as windbreaks or as focal trees in the landscape. However, conifers including certain species of spruce, pine, hemlock, cedar and fir planted in northern areas of North...

The North American crop wild relatives (CWR) of lettuce (Lactuca L.) represent an underexplored
pool of genetic diversity of potential value to breeding programs.  In this review, we examine the role of herbarium and genebank holdings in...

The Red List of US Oaks report details for the first time the distributions, population trends, and threats facing all 91 native oak species in the U.S. using the IUCN Red List threat assessment platform, including updated versions of previously...

Botanic gardens conserve plant diversity ex situ and can prevent extinction through integrated conservation action. Here we quantify how that diversity is conserved in ex situ collections across the world’s botanic gardens. We reveal that botanic...

Oak decline is a slow-acting disease complex that involves the interaction of biotic and abiotic factors such as climate, site quality and advancing tree age. Oak decline occurs more commonly among red oak species, but white oaks are susceptible as...

Horticultural plants play various and critical roles for humans by providing fruits, vegetables, materials for beverages,and herbal medicines and by acting as ornamentals. They have also shaped human art, culture, and environments and thereby have...

Crop wild relatives, the wild progenitors and closely related cousins of cultivated plant
species, are sources of valuable genetic resources for crop improvement. Persisting gaps
in knowledge of taxonomy, distributions, and...

Urbanization is a large driver of biodiversity globally. Within cities, urban trees, gardens, and residential yards contribute extensively to plant biodiversity, although the consequences and mechanisms of plant cultivation for biodiversity are...

Interception of potential invasive species at ports-of-entry is essential for effective biosecurity
and biosurveillance programs. However, taxonomic assessment of the immature stages
of most arthropods is challenging; characters for...

More than 450 scientists from around the world recently released findings showing that up to one million species may become threatened with extinction. At a time when scientists are calling for strengthened biodiversity protections, the United States...

This webinar was brought to you by the Natural Areas Association.

Presented by Sarah Wurzbacher, Forestry Extension Educator, Penn State University.

Urban forests are recognized for the multiple benefits they provide to city‐dwellers.
However, climate change will affect tree species survival and persistence in urban
ecosystems. Tree failures will cause economic losses and jeopardize...

Orchid viruses are capable of causing flower deformities and death, which can severely
impact the horticultural industry and wild orchid conservation. Here we show
how two of these quickly evolving viruses display few genetic differences...

Grain legumes provide a rich resource of plant nutrition to human diets and are vital for food security and sustainable cropping. Heat stress during flowering has a detrimental effect on legume seed yield, mainly due to irreversible loss of seed number...

The World Flora Online (WFO) project was initiated in 2012 in response to Target 1 of the Congress on Biological Diversity's Global Strategy for Plant Conservation (GSPC) – "To create an online flora of all known plants by 2020". Target 1 is intended...

The U.S. national heritage of approximately one billion biodiversity specimens, once
digitized, can be linked to emerging digital data sources to form an information-rich network
for exploring earth’s biota across taxonomic, temporal and...
