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

- Scientists call for climate projections as part...on April 16, 2021 at 4:42 pm
Scientists have called for the use of climate projections in conservation planning, to ensure that areas most at risk from biodiversity loss and climate impacts are protected. Protected areas are often created in areas of low population density and remote locations, rather than because of their biodiversity conservation potential. Conservation planning in tropical forests especially tends to be less rigorous and climate rarely taken into account, they said.

Even the mention of parasites can be enough to make some people's skin crawl. But to recent UC Santa Barbara doctoral graduate Dana Morton these creepy critters occupy important ecological niches, fulfilling roles that, in her opinion, have too often been overlooked.
- Deciduous trees offset carbon loss from Alaskan...on April 15, 2021 at 6:00 pm
More severe and frequent fires in the Alaskan boreal forest are releasing vast stores of carbon and nitrogen from burned trees and soil into the atmosphere, a trend that could accelerate climate warming. But new research published this week in the journal Science shows that the deciduous trees replacing burned spruce forests more than make up for that loss, storing more carbon and accumulating it four times faster over a 100-year fire interval. The study, led by a team of researchers at the […]

In January 2021, Storm Christoph pummelled the United Kingdom with heavy rains and the threat of unmanageable runoff. But in flood-prone Manchester, a newly developed park was proving its worth.
- 97% of Earth's land area may no longer be...on April 15, 2021 at 7:26 am
Only between 2% and 3% of the Earth's terrestrial surface can be considered ecologically intact, according to a new study published in Frontiers in Forests and Global Change. This percentage is drastically lower than past assessments, which estimated it to be between 20% and 40%, because it factored in loss of species from intact habitat as well as reduced populations of species. A restoration focus of specific species in intact habitat could recover ecological integrity to about 20% of land.
