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...

Poison ivy is irritating, but this unpopular native plant also has underappreciated superpowers. This article gives you information about how to spot it and deal with it.

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...

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...

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...

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...

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...

Emerald ash borer (Agrilus planipennis) was first discovered in southeastern Michigan in 2002. Accidentally introduced on solid wood packing material from Asia, EAB has since spread to nearly all states within the native North American range of its...

Palms (Arecaceae) are a relatively speciose family and provide materials for food, construction, and handicraft, especially in the tropics. They are frequently used as paleo-indicators for megathermal climates, and therefore, it is logical to predict...

Climate change and an increase in disturbed bee habitats from expanding agriculture and development in northeastern North America over the last 30 years are likely responsible for a 94 per cent loss of plant-pollinator networks, York University...

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....

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....
