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

Prairies once covered an enormous area of North America, but today have been reduced to a small fraction of this historical range. Imagine an area the size of Texas, the second largest state, shrinking over the course of decades to an area the size of Massachusetts, the sixth smallest state.

Mangrove trees—valuable coastal ecosystems found in Florida and other warm climates—won't survive sea-level rise by 2050 if greenhouse gas emissions aren't reduced, according to a Rutgers co-authored study in the journal Science.
Peatland drainage in Southeast Asia adds to...

In less than three decades, most of Southeast Asia's peatlands have been wholly or partially deforested, drained, and dried out. This has released carbon that accumulated over thousands of years from dead plant matter, and has led to rampant wildfires that spew air pollution and greenhouse gases into the atmosphere.

The polar willow (Salix polaris) may not seem like much when you look at it—just a jumble of tiny green leaves in a dense mat that pokes out of the tundra.
