forest : a dense growth of trees and underbrush covering a large tract — Webster
Forest is a large area dominated by trees. Hundreds of more precise definitions of forest are used throughout the world, incorporating factors such as tree density, tree height, land use, legal standing and ecological function.
Forests are the dominant terrestrial ecosystem of Earth, and are distributed around the globe. Forests account for 75% of the gross primary productivity of the Earth’s biosphere, and contain 80% of the Earth’s plant biomass. Net primary production is estimated at 21.9 gigatonnes carbon per year for tropical forests, 8.1 for temperate forests, and 2.6 for boreal forests.
Forests at different latitudes and elevations form distinctly different ecozones: boreal forests near the poles, tropical forests near the equator and temperate forests at mid-latitudes. Higher elevation areas tend to support forests similar to those at higher latitudes, and amount of precipitation also affects forest composition. — Wikipedia
Forestry is the science and craft of creating, managing, using, conserving, and repairing forests, woodlands, and associated resources to meet desired goals, needs, and values for human and environment benefits. The science of forestry has elements that belong to the biological, physical, social, political and managerial sciences.
Modern forestry generally embraces a broad range of concerns, in what is known as multiple-use management, including the provision of timber, fuel wood, wildlife habitat, natural water quality management, recreation, landscape and community protection, employment, aesthetically appealing landscapes, biodiversity management, watershed management, erosion control, and preserving forests as ‘sinks’ for atmospheric carbon dioxide. A practitioner of forestry is known as a forester. Other common terms are: a verderer, or a silviculturalist. Silviculture is narrower than forestry, being concerned only with forest plants, but is often used synonymously with forestry.
Forest ecosystems have come to be seen as the most important component of the biosphere, and forestry has emerged as a vital applied science, craft, and technology. — Wikipedia

A study reveals an unprecedented change in the fire regime in Europe which is related to climate change. The affected areas are in Southern, Central and Northern Europe but this historical change in Europe's fire regime is more intense in the Mediterranean area. The study, published in the journal Scientific Reports, is led by Jofre Carnicer, lecturer of Ecology at the Faculty of Biology, and member of the Biodiversity Research Institute (IRBio) of the University of Barcelona and the Centre for […]

A hallmark of environmental science is understanding how ecosystems respond to global change. Much of this research focuses on short-term ecosystem responses, such as how an ecosystem responds to a sudden onset of drought. But previous conditions can modify that response. In the same way a formative childhood experience might change how an adult responds to stress, legacy effects can change the direction or magnitude of ecosystem responses to disturbance.

A bar of chocolate in the U.S. might have been made in Belgium, with cocoa from the Ivory Coast, almonds from Morocco, vanilla from Madagascar and sugar from Brazil. Were forests cut down for it? Were forced or child laborers involved in the harvest? Were toxins used or rivers polluted?

Humans have raised CO₂ levels in the atmosphere to 50% above what they were before the industrial revolution. As a result, the world has already warmed by 1.1°C over the past century and reports indicate that it could reach 2.7°C of warming by the end of this century.

International research led by Dr. Tom Van der Stocken of the VUB Biology Department examined 21st century changes in ocean-surface temperature, salinity, and density, across mangrove forests worldwide. The study suggests that changes in surface-ocean density may impact the dispersal patterns of widely distributed mangroves species, and more likely so in the Indo-West Pacific region, the primary hotspot of mangrove diversity. The study is published in Nature Climate Change.
