Oaks are critical to the health and function of forest and shrubland habitats in the United States, but many native oaks are threatened with extinction in the wild. Ongoing conservation efforts exist for some species, but with growing threats and...
Intensively managed landscapes, like those found in many public gardens, attempt to mitigate the impact of significant weather events through irrigation, improving soil characteristics, and mulching. At the same time many gardens purposefully push the...
Participants will learn about the potential impacts of climate change on 125 tree species of the eastern US. Changes in suitable habitat, capacity to cope with the changing climate, and potential for infilling or migration by the end of this century...
This publication provides forest resource statistics contributing to the 2020 Resources Planning Act (RPA) Assessment to provide current information on the Nation’s forests. Resource tables present estimates of forest area, volume, mortality, growth,...
Fact Sheets & Plant Guides is a partnership of the National Plant Data Team and the Plant Materials Program. Fact Sheets provide brief descriptions of a plant, its uses, and cultural recommendations. Plant Guides are similar but more extensive....
To understand and forecast biological responses to climate change, scientists frequently use field
experiments that alter temperature and precipitation. Climate manipulations can manifest in complex ways, however, challenging interpretations of...
Davallia solida (G. Forst.) Sw. (Davalliaceae), Phlebodium aureum (L.) J. Sm. (Polypodiaceae), Phlebodium pseudoaureum (Cav.) Lellinger (Polypodiaceae), and Rumohra adiantiformis (G. Forst.) Ching (Dryopteridaceae) are epiphytic ferns native to the...
Urban trees serve a critical conservation function by supporting arthropod and vertebrate communities but are often subject to arthropod pest infestations. Native trees are thought to support richer arthropod communities than exotic trees but may also...
In the Tropical Andes millions of people depend upon the use of wild and domesticated
biodiversity for their livelihoods, but the complex interactions between the
ecological and social components of the region’s ecosystems remain poorly...
A major challenge in articulating human dimensions of climate change lies in translating global climate forecasts into impact assessments that are intuitive to the public. Climateanalog mapping involves matching the expected future climate at a...
Sunflower is a unique model species for assessing crop responses and adaptation to climate change. We provide an initial assessment of how climate change may influence the abiotic and biotic environment of cultivated sunflower across the world. We find...
The report Climate Change in the American Mind documents a continued upward trend in Americans’ concern about global warming, as reflected in several key indicators tracked since 2008, including substantial increases in Americans’ certainty...
The PCA welcomed Doug Tallamy, Mary Phillips, John Rowden, and Judy Venonsky as panelists (Moderated by Casey Sclar) on “Identifying and addressing information gaps in plant databases to support emerging planting design technologies promoting...
To address the growing interest and expressed need for pollinator management strategies a special pollinator symposium was held at the 2017 annual conference of the Natural Areas Association, curated by William Carromero of the US Forest Service and...
Authored by more than 200 scientists from the United States, Canada, and Mexico, the Second
State of the Carbon Cycle Report (SOCCR2) provides an up-to-date assessment of scientific
knowledge of the North American carbon cycle. This...
The impacts of climate change are already being felt in communities across the country.
More frequent and intense extreme weather and climate-related events, as well as changes
in average climate conditions, are expected to continue to...
The below case studies were collected and shared in a September 2018 Newsletter from the Center for Plant Conservation.
Based on an interview with Denise Knapp, Director of...
In a pollen supplementation experiment, fruit or seed production by flowers exposed to natural pollination is compared to that following hand pollination either by pollen supplementation (i.e. manual outcross pollen addition without bagging) or manual...
Functional traits are increasingly used to understand the ecology of plants and to predict their responses to global changes. Unfortunately, trait data are unavailable for the majority of plant species. The lack of trait data is especially prevalent...
For many species and seed sources used in restoration activities, specific seed germination
requirements are often unknown. Because seed dormancy and germination traits can be
constrained by phylogenetic history, related species are often...
