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

Droughts impact millions of people and threaten the delicate ecosystems of the Amazon rainforest in South America. Now a study within the TiPES project by Catrin Ciemer of the Potsdam Institute for Climate Impact Research (PIK), Germany, and colleagues in Environmental Research Letters has revealed how surface temperatures in two coupled areas of the tropical Atlantic Ocean can be used to accurately predict these severe climate events. Early warnings of upcoming droughts are imperative for […]

Mountains and butterflies are conceptualized as the ultimate juxtaposition—enduring and resolute versus fleeting and delicate—but the surprising robustness of alpine butterflies could help scientists better understand the impact climate change is having on mountains.
Discovery of a new mass extinction
on September 16, 2020 at 6:00 pm
It's not often a new mass extinction is identified; after all, such events were so devastating they really stand out in the fossil record. In a new paper, published today in Science Advances, an international team has identified a major extinction of life 233 million years ago that triggered the dinosaur takeover of the world. The crisis has been called the Carnian Pluvial Episode.
