Traditional Japanese Garden plants languish in hot dry zones. Selecting alternative plants more suited for these climates increases success and enjoyment of your garden.. The plants highlighted in this article are selected for hardiness and suitability...
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...
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...

A widely accepted approach to assess extinction risk, and a key source of data underpinning the IPBES report, is the IUCN Red List of Threatened Species (hereafter Red List). However, with only 9%of plants represented by assessments at the latest...
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...
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...
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...
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...

Indigenous communities rely extensively on plants for food, shelter, and medicine. It is still unknown, however, to what degree their survival is jeopardized by the loss of either plant species or
knowledge about their services. To fill this gap...
Born as a center for the treatment of addiction and mental health and for the research on traditional Amazonian medicine, the Takiwasi Center, located in the Peruvian high-Amazon, over more than 25 years of existence has developed a series of parallel...
North American forests and forest management institutions are experiencing a wide range of significant ecological disturbances and socioeconomic changes, which point to the need for enhanced resilience. A critical capacity for resilience in...
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...
A new study shows that even the most populous city in the United States contains significant stands of forest dominated by native tree species. The findings, which appear in the journal Ecological Applications, underscore the importance of studying...
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...
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...
Recent studies have shown that the use of native plants by landscape architects and contractors in the southeastern United States has increased as has the clientele interest level in native plants. Recommendations to increase the use of native species...
