Urgent solutions to global climate change are needed. Ambitious tree-planting initiatives, many already underway, aim to sequester enormous quantities of carbon to partly compensate for anthropogenic CO2 emissions, which are a major cause of rising...

Echinacea, also known as coneflowers, are immensely popular and iconic native plants that are prized for their beauty as well as their purported medicinal qualities. The nine species of Echinacea are native to North America and are primarily found in...

Plantings of native flowers are often installed to increase the pollinator habitat in urban and suburban gardens. However, in many regions, it is not known which native plants are best used for pollinator plantings in gardens. Candidate plants must be...

The COVID-19 pandemic is causing many victims worldwide and has generated a serious economic crisis. Substantial changes have occurred in the food and ornamental production chains. The aim of the present review has been to summarize some of the main...

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...

To repair ecological damage caused by construction, landscape managers typically apply restoration techniques - but what if these activities further damage the ecology? Invasive Phytophthora pathogens have been inadvertently introduced to...

On March 25, 2021, the Somerville, MA City Council unanimously passed a first-of-its-kind ordinance requiring that plantings on city-owned land be composed primarily of local native plants.

Local advocacy group Green & Open Somerville has...

Naples Botanical Garden is one of the first public gardens to create an Emergency Action Plan specific to addressing a pandemic with procedures and operations outlined within. 

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...

Climate change and biological invasion are major threats to biodiversity, but their combined effects haverarely been quantified. The introduction of congeneric non-native species, in particular, can be especially problematic for native species due to...

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,...

Botanical gardens have contributed to plant conservation through the maintenance of both living 20 and preserved plant specimens for decades. However, there is still a large gap in the literature 21 with regards to understanding the potential...

A policy document developed to balance the public garden mission of holding diverse horticultural collections with the conservation mission of preserving natural areas and the broader environment.

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-...

This is a companion resource to a presentation given by Tim Boland, Polly Hill Arboretum, entitled The American Oaks: Diversity, Ecology, Identification as part of the "A Focus On Sustainability" Webinar Series.

The term “urban forest” is often used to refer to all the trees within a city or town. But the urban forest is part of a much larger social-ecological landscape that supports a complex web of biodiversity, ecosystem services, values, and cultures.  The...

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...
