Biochar is a term used to describe charred, organic material that is applied to soils with the intent to improve soil properties. Many sources of organic matter may be used, but can impact the properties of the biochar. Biochar differs from charcoal because its components are specially formulated and optimally balanced for soil. Current interest in biochar has been inspired by the historical use of charcoal to amend “terra preta” and “terra mulata” soils in the Amazon Basin.

Intersecting urban forestry and botanical gardens to address big challenges for healthier trees, people, and cities
Improving urban forests is one of the solutions to achieving several of the United Nations Sustainable Development Goals and making cities healthier and more livable for people. Priority should be given to protecting mature trees and promoting long‐lived trees in the future. Achievement of this goal requires recognition of the myriad stresses trees face in built landscapes as well as the challenges related to climate change.
It has become apparent that there is need for actionable steps that member institutions can take to become more welcoming for their visitors, staff, and volunteers. The “Creating a More Diverse, Equitable, and Inclusive Garden” workshop was born from this need. Based in positive organizational scholarship, this workshop has been developed so that any garden can adapt the activities based on their particular needs and resources, resulting in manageable action steps towards becoming more diverse and inclusive.

For the past several years, many college horticulture programs have experienced a decline in undergraduate enrollment, resulting in the elimination of some degrees. In this study, we compared postsecondary U.S. horticulture program availability from a survey completed in 1997 with offerings existing in 2012 and 2017. In 1997, 446 U.S. postsecondary institutions offered degrees and/or certificates in horticulture. In 2012, this number had decreased by 43% to 253 institutions, which included 98 with 4-year degrees, 215 with 2-year degrees, and 138 with certificate programs.

This resource developed by the 2018-2019 Longwood Fellows cohort provides a framework that senior-level leaders can use to assess their organizations. It offers specific reasoning, definitions, and strategies—the why, what, and how—for topics that are both challenging and important: organizational culture, individual staff, and the board. Each topic is nuanced, yet related, because each, at its core, relates to people. These assessment strategies are based on experiences of garden leaders from around the world, whose quotes are intended to guide and inspire the reader
Forest Resources of the United States, 2017: A Technical Document Supporting the Forest Service 2020 RPA Assessment
This publication provides forest resource statistics contributing to the 2020 Resources Planning Act (RPA) Assessment to provide current information on the Nation’s forests. Resource tables present estimates of forest area, volume, mortality, growth, removals, and timber-product output in various ways within the context of changes since 1953. Additional analyses look at the resource from an ecological, health, and productivity perspective.
