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...

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...

The Morton Arboretum has released the results of its 2020 Chicago region tree census. Findings include the loss of an estimated 6 million ash trees, felled by the emerald ash borer. Chicago's canopy cover decreased from 19% to 16%, largely because of...

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...

Results are in from one of the most significant studies ever completed on Delaware’s bees. From 2018-2019, Mt. Cuba Center partnered with Matthew J. Sarver of Sarver Ecological to scientifically measure which species of bees were attracted to our...

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...

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,...

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...

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...

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...

Soils are fundamental to agriculture and food security. With limited agricultural land and the complications posed by climate change, it is critical to maintain and strive to improve working soils to ensure a resilient future. Improved soil carbon and...

The guide provides a detailed the native plants of New York that are crucial for supporting native specialist bees; including, where the region or habitat the plant occurs naturally, date of bloom, color of bloom, plant structure, how to obtain seeds...

Many are well aware of the inequitable distribution of trees in our urban areas.  Black, indigenous, and people of color (BIPOC) communities often face the greatest burden of heat, air pollution, and flooding all of which urban greening can help to...

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....

Learn about conserving bumble bees in natural areas presented by Rich Hatfield. 

This document was developed as a contribution to “mainstreaming biodiversity
into agriculture, forestry and fisheries”, as recommended at the 24th Session of the
Committee on Forestry in 2018. It also contributes to FAO’s Strategic...

The use of livestock to control undesirable vegetation is growing in popularity. However, less is known about the pros and cons of this technique in comparison to other management methods, such as herbicide, cutting, and burning. In this webinar, Dr....

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....

It is widely recognized that actions aimed at conserving, restoring and sustainably manage nature will not only help address biodiversity loss and deterioration of ecosystems but also contribute to climate change mitigation, resilience and adaptation....
