Southern pine species such as loblolly, longleaf, shortleaf, and slash cover much of the 
southeastern U.S., and are a critical component of the region’s economy.  Loblolly pine is the 
most widely planted species in the southeastern...

The emerald ash borer (EAB) is an exotic forest pest that has killed millions of ash trees in the 
United States and Canada, resulting in an ecological disaster and billions of dollars in economic 
losses of urban landscape and forest...

Large-scale global reforestation goals have been proposed to help mitigate climate change and provide other ecosystem services. To explore reforestation potential in the United States, we used GIS analyses, surveys of nursery managers and foresters,...

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-...

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...

Learning to distinguish the symptoms of lightning strikes is a valuable tool for arborists, landscapers, pest control companies, and gardeners. The symptoms may be confused with other causes such as lethal yellowing disease (Candidatus palmae...

Periodic fires are a normal part of the lifecycle of many ecosystems, but climate change is creating mega-fires that instead of supporting biodiversity threaten to destroy it. In the aftermath of the worst fire season in Australia’s recorded history,...

Since a devastating fungal blight popped up in the Bronx Zoo in 1904 and went on to kill at least 3 billion chestnut trees, North American forests have been swept by one plague after another, including a fungus that kills elms and an aphidlike insect...

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...

The millennial generation, born between 1981 and 1996, is the largest demographic age group in the United States. This generation of plant enthusiasts has experienced financial setbacks; nevertheless, they collectively wield immense economic power. In...

As COVID continues to be a global concern and as many organizations are finding new normal ways to work, there is concern for workplace overexertion and fatigue. Overexertion can be a result of physical or emotional strain or pressure caused when you...

Diversification of urban forests is essential to enhance their resilience to future biotic
threats as well as those posed by a changing climate. Arboreta and botanic gardens
host a wide range of plant material that can be evaluated to...

Prior to Workshop  - 

1. Each registrant should read the attached Guidelines for Listing, Categorizing and Sharing Information on Plant Taxa Spreading from Cultivation at Public Gardens in North America (Guidelines).

The Fall and Winter seasons signal many beautiful changes in the Garden landscape; from colorful leaves to Holiday Lights. Fall and Winter also signals the beginning of the flu season, which according to the Center for Disease Control and Prevention (...

Pivoting from in-person to virtual events is never easy, especially when a pandemic is the root cause of the shift. In an effort to share tips, tricks, and insights from the American Public Gardens Associations' shift from an in-person to virtual event...

Positive interactions between people and nature inspire behaviours that are in harmony
with biodiversity conservation and also afford physical and mental health benefits.
Since most people live in towns and cities, urban greenspaces are...

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...

“Plant blindness” is the cause of several problems that have plagued botany outreach
and education for over a hundred years. The general public largely does not notice
plants in their environment and therefore do not appreciate how...

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...
