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....

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....

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...

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....

Historic urban grasslands include greenspaces of historic value designed for passive and active recreation in the human built environment. Urban grasslands such as cemeteries and parks present unique challenges to landscapes designed in the early...

We partnered with various federal, state, and private interests to evaluate the floristic composition at the Garden City Terminal of the Port of Savannah, Georgia, USA. We conducted the following study to demonstrate the collaborative relationship-...

Ash tree species in North America are under mortal threat from the Emerald Ash Borer (EAB), now in 35 states and five Canadian provinces. There are ongoing efforts to conserve this native tree species by producing genetically diverse, resistant...

Mycorrhizal fungi, of all types, hold huge significance for our planet and society. By forming mutualistic symbioses with the vast majority of land plants, mycorrhizas play an essential role
in the formation and maintenance of global ecosystems...

Public botanical gardens and arboreta are living museums and as such, their core missions
include the collection and display of herbaceous and woody plants from their local region or
from around the world. To fulfil this mission, gardens...

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...

The Red List of US Oaks report details for the first time the distributions, population trends, and threats facing all 91 native oak species in the U.S. using the IUCN Red List threat assessment platform, including updated versions of previously...

Oak decline is a slow-acting disease complex that involves the interaction of biotic and abiotic factors such as climate, site quality and advancing tree age. Oak decline occurs more commonly among red oak species, but white oaks are susceptible as...

Crop wild relatives, the wild progenitors and closely related cousins of cultivated plant
species, are sources of valuable genetic resources for crop improvement. Persisting gaps
in knowledge of taxonomy, distributions, and...

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...

This webinar was brought to you by the Natural Areas Association.

Presented by Sarah Wurzbacher, Forestry Extension Educator, Penn State University.

Urban forests are recognized for the multiple benefits they provide to city‐dwellers.
However, climate change will affect tree species survival and persistence in urban
ecosystems. Tree failures will cause economic losses and jeopardize...

Grain legumes provide a rich resource of plant nutrition to human diets and are vital for food security and sustainable cropping. Heat stress during flowering has a detrimental effect on legume seed yield, mainly due to irreversible loss of seed number...
