Urgent solutions to global climate change are needed. Ambitious tree-planting initiatives, many already underway, aim to sequester enormous quantities of carbon to partly compensate for anthropogenic CO2 emissions, which are a major cause of rising...

Scientists’ research interests are often skewed toward charismatic organisms, but quantifying research biases is challenging. By combining bibliometric data with trait-based approaches and using a well-studied alpine flora as a case study, this...

In the first webinar, Getting Started with GIS, we looked at the value of GIS for public gardens and how you can start down the path to using this technology to support your institution. In this webinar, users will see demonstrations that dive deeper...

The Western Association of Fish & Wildlife Agencies (WAFWA), in partnership with Bureau of Land Management (BLM), U.S. Fish and Wildlife Service (USFWS), U.S. Geological Survey (USGS), Intermountain West Joint Venture (IWJV) and other conservation...

The United States Botanic Garden and the American Public Gardens Association are working to support public gardens and their partners in facilitating collaborative food-growing and education programs. For 2021, the...

Several biotic and abiotic stressors, including insects, pathogens, and weather, can impact pine growth in the Southeast. Dr. David Coyle (Clemson University) will provide a general overview of identification, impact, and management strategies for pine...

Holding a Nationally Accredited Plant Collection™  is added recognition of your institution’s long-term commitment to plant collections preservation, and to achieving a high standard of excellence in plant collections management. In this presentation,...

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-...

Natural disasters cause significant damage each year to our urban forests, and years of local investment in planting and caring for community trees can be suddenly wiped away. We know that urban forest and community resilience can be improved by using...

A Focus on Sustainability is a collaborative series between the Ecological Landscape Alliance, Chesapeake Conservation Landscaping Council, ReScape, Deep Roots Kansas City, and the American Public Gardens Association....

Triage for Living Collections - Discussing Critical Action in the Wake of Disaster

If 2020 has taught us anything it’s that when disaster strikes, we need to be ready to react. The Plant Collections Community invites you to view...

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...

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 ...

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...

Dr. Kay Havens, Chair of the PCA Non-Federal Cooperators Committee, will briefly report on the "Assessment of Native Seed Needs and Capacities" being conducted by the National Academies of Sciences, Engineering, and Medicine, including the phase 2 data...

This report describes the first phase of an examination of some of the nation’s needs for
native plant seeds (a shorthand term to include all forms of native propagative plant material)
and of the capacity to meet those needs. Across the...

Lindsey Purcell, Urban Forestry Specialist – Purdue University, as he outlines examples and case studies regarding tree appraisal in the urban environment. 

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...

Diameter at Breast Height (DBH) is an enormously important metric for foresters, arborists, researchers, contractors, and the general public. With single-stemmed species, it is used to estimate timber volume, biomass, ecosystem services, and...
