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

- Dryer, warmer night air is making some Western...on August 5, 2021 at 4:57 pm
Firefighters have reported that Western wildfires are starting earlier in the morning and dying down later at night, hampering their ability to recover and regroup before the next day's flareup.

Giant bird-eating centipedes may sound like something out of a science-fiction film—but they're not. On tiny Phillip Island, part of the South Pacific's Norfolk Island group, the Phillip Island centipede (Cormocephalus coynei) population can kill and eat up to 3,700 seabird chicks each year.
- Roadside ditches are effective at nitrogen removalon August 4, 2021 at 1:43 pm
Roadside ditches are a catchall for water, from both sheets of rain that fall on roads and runoff from lawns or fields. Although ditches are ubiquitous in the landscape, they have the potential to be much more than a storm water conduit. In fact, ditches are human-made lowlands that often act as wetlands, complete with fluctuating water levels and a broad array of vegetation and microbes.
- Climate change is already disrupting US forests...on August 4, 2021 at 1:30 pm
Record-breaking heat waves and drought have left West Coast rivers lethally hot for salmon, literally cooked millions of mussels and clams in their shells and left forests primed to burn. The extraordinary severity of 2021's heat and drought, and its fires and floods, has many people questioning whether climate change, fueled by human actions, is progressing even faster than studies have predicted and what that means for the future.

Illustrations depicting the dinosaur era—whether in books or movies—are often accompanied by lush greenery. During the Cretaceous period, the trees commonly dominating a wide range of Earth's terrestrial environments were conifers—similar to the pines, spruces, cypresses and cedars that populate the earth today. These conifers played a key role in ecosystems, providing nourishment, nutrients, and habitat for a range of prehistoric creatures.
