Bartlett: Needle Diseases of Conifers

Needlecast and needle blight are terms applied to a variety of foliage disorders of many coniferous species. These diseases are usually more severe on young trees or on trees growing outside of their natural range. Disease severity and corresponding...

A Landscape-Level Assessment of Restoration Resource Allocation for the Eastern Monarch Butterfly

The Monarch butterfly eastern population (Danaus plexippus) is in decline primarily due to habitat loss. Current habitat restoration programs focus on re-establishing milkweed, the primary food resource for Monarch caterpillars, in the central United...

Terpen-tales: The mystery behind the unique fragrance of lavender

Even the mention of lavender evokes the distinct fragrance of the flower. This beautiful flower has been used to make perfumes and essential oils since time immemorial. The aesthetics of the flower have captured imaginations worldwide. So what makes...

Challenges to the Reforestation Pipeline in the United States

This article from Frontiers in Forests and Global Change explores large-scale global reforestation goals in the US. The authors used GIS analyses, surveys of nursery managers and foresters, and literature synthesis to assess the opportunities and...

Loblolly Pine Health in the Southeastern U.S.

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...

Challenges to the Reforestation Pipeline in the United States

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,...

The PhenObs initiative – A standardised protocol for monitoring phenological responses to climate change using herbaceous plant species in botanical gardens

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...

Climate change and wildfires: lessons from Australia’s Blue Mountains

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,...

Can an ambitious breeding effort save North America’s ash trees?

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...

Crop wild relatives of the United States require urgent conservation action

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...

The global tree restoration potential

The restoration of trees remains among the most effective strategies for climate change
mitigation.We mapped the global potential tree coverage to show that 4.4 billion hectares
of canopy cover could exist under the current climate....

Reshaping the future of ethnobiology research after the COVID-19 pandemic

A geographically diverse group of 29 ethnobiologists addresses three common themes in response to the COVID-19 global health crisis: impact on local communities, future interactions between researchers and communities, and new (or renewed) conceptual...

Access to crop digital information and the sharing of benefits derived from its use: Background and perspectives

Today's genebanks are essential to maintaining the resilience of the global agricultural system in the face of climate change, new pests and diseases, shifts in trade and dietary preferences, natural
resource limitations, and armed conflicts....

Scientists’ incentives and attitudes toward public communication

In an era of large-scale science-related challenges and rapid advancements in groundbreaking science with major societal implications, communicating about science is critical. The profile of
science communication has increased over the last few...

A Master Gardener Survey: Promoting Pollinator-friendly Plants Through Education and Outreach

As land-use patterns change over time, some pollinating insects continue to decline both in abundance and diversity. This is due, in part, to reductions in floral resources that provide sufficient nectar and pollen. Our overall goal is to help increase...

Spending at least 120 minutes a week in nature is associated with good health and wellbeing

A growing body of epidemiological evidence indicates that greater exposure to, or ‘contact with’, natural environments (such as parks, woodlands and beaches) is associated with better health and well-being, at least among populations in high income,...

Can invasive species replace native species as a resource for birds under climate change? A case study on bird-fruit interactions

Wild fruits are an important food source for many north temperate-breeding landbirds during autumn migration and, in turn, birds provide the service of seed dispersal. Despite the importance of these autumn interactions, their potential to shift with...

Lightning Protection for Trees

Thousands of trees are struck by lightning every year. These trees will have varying degrees of damage ranging from complete shattering and destruction of the tree, to a slow lingering death, to virtually no apparent damage at all (Figure 1). When...

An Update of the Literature Supporting the Well-Being Benefits of Plants: Part 3 - Social Benefits

This paper provides evidence from the literature regarding the social benefits associated with plants and how they influence the physiological, psychological, and cognitive well-being constructs affecting quality of life. These benefits are segmented...

Scientistsʼ Warning on Climate Change and Medicinal Plants

The recent publication of a World Scientistsʼ Warning to Humanity highlighted the fact that climate change, absent strenuous mitigation or adaptation efforts, will have profound negative effects for humanity and other species, affecting numerous...
