The American Public Gardens Association is partnering with the United States Forestry Service’s Forest Health Protection to establish living gene banks of US tree species at risk, by collecting plant material (seed, cuttings, as appropriate) from...
Ten years ago the Royal Botanic Gardens Victoria embarked on an ambitious project to collect, treat and distribute storm water from the catchment within and around the botanic garden. The infrastructure of wetlands filtration, a sophisticated water ...
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....
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...
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...
Oaks are critical to the health and function of forest and shrubland habitats in the United States, but many native oaks are threatened with extinction in the wild. Ongoing conservation efforts exist for some species, but with growing threats and...
Contact your elected representatives and let them know how you feel about plants, our web of life, and the ecosystem services we all depend upon:

Canada is home to about 5087 species of higher plants of which 25% were introduced to Canada either deliberately or by accident. The richness of botanical species is highest in the southern, more densely settled parts of the country. About 364 native...
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...
Originating in Europe in the 16th century, botanic gardens are found in nearly every country in the world. Botanic gardens have had various roles during this time, including as physic gardens, as adaptation centers for commercial crops, as pleasure...
In this report, we investigate how integrating components of oak woodlands into developed landscapes — “re-oaking” — can provide an array of valuable functions for both wildlife and people. Re-oaking can increase the biodiversity and ecological...
The first TGI report, published in 2015, identified eight critical gaps slowing the transfer of stress-adapted trees from upstream research to forest owners and managers. The gaps fell into three categories: Innovation, Policy, and Markets. TGI members...
“Which plants should I grow, and how many?” The IMLS National Leadership Project, Safeguarding our Tree Collections, seeks to answer this fundamental question. Through structured comparisons of genetic data among major groups of seed plants, management...
In 2012, more than two million acres of important sage-brush habitat burned in four Western States. In the East, Hurricane Sandy caused not only widespread damage to homes and businesses, but also to native plant communities that stabilize soils and...
Centennial Trees is a nine-year-old outreach program of the Birmingham Botanical Gardens that educates the community on the importance of planting locally-sourced native tree seedlings in public spaces. Trees selected for the program are determined to...
Earth has daunting climatic and socioeconomic challenges. Gardens wish to do their part in preserving biodiversity, but best practices are essential when working with and protecting wild populations. We will...
Arboreta and gardens have an ability to fill an important role in germplasm conservation by participating in ex situ collections. Globally, trees are facing a human-driven mass extinction, and our native flora...
