Forest in the context of Brown bears

World Heritage Sites are landmarks and areas with legal protection under an international treaty administered by UNESCO for having cultural, historical, or scientific significance. The sites are judged to contain "cultural and natural heritage around the world considered to be of outstanding value to humanity".

To be selected, a World Heritage Site is nominated by its host country and determined by the UNESCO's World Heritage Committee to be a unique landmark which is geographically and historically identifiable, having a special cultural or physical significance, and to be under a sufficient system of legal protection. World Heritage Sites might be ancient ruins or historical structures, buildings, cities, deserts, forests, islands, lakes, monuments, mountains, wilderness areas, and others.

Forestry is the science and craft of creating, managing, planting, using, conserving and repairing forests and woodlands for associated resources for human and environmental benefits. Forestry is practiced in plantations and natural stands. The science of forestry has elements that belong to the biological, physical, social, political and managerial sciences. Forest management plays an essential role in the creation and modification of habitats and affects ecosystem services provisioning. A practitioner of forestry is known as a forester.

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.

In geography, a plain, commonly known as flatland, is a flat expanse of land that generally has few rapid or steep changes in elevation. Natural vegetation in plains can include prairies/grasslands, forests, savanah, tundra, and desert biomes, among others. Plains occur as lowlands along valleys or at the base of mountains, as coastal plains, and as plateaus or uplands. Plains are one of the major landforms on earth, being present on all continents and covering more than one-third of the world's land area. Plains in many areas are important for agriculture. There are various types of plains, and biomes on them.

Deforestation or forest clearance is the removal and destruction of a forest or stand of trees from land that is then converted to non-forest use. Deforestation can involve conversion of forest land to farms, ranches, or urban use. About 31% of Earth's land surface is covered by forests at present. This is one-third less than the forest cover before the expansion of agriculture, with half of that loss occurring in the last century. On average 2,400 trees are cut down each minute. Estimates vary widely as to the extent of deforestation in the tropics. In 2019, nearly a third of the overall tree cover loss, or 3.8 million hectares, occurred within humid tropical primary forests. These are areas of mature rainforest that are especially important for biodiversity and carbon storage.

The direct cause of most deforestation is agriculture by far. More than 80% of deforestation was attributed to agriculture in 2012. Forests are being converted to plantations for coffee, palm oil, rubber and various other popular products. Livestock grazing also drives deforestation. Further drivers are the wood industry (logging), urbanization and mining. The effects of climate change are another cause via the increased risk of wildfires (see deforestation and climate change).

Environmental laws are laws that protect the environment. The term "environmental law" encompasses treaties, statutes, regulations, conventions, and policies designed to protect the natural environment and manage the impact of human activities on ecosystems and natural resources, such as forests, minerals, or fisheries. It addresses issues such as pollution control, resource conservation, biodiversity protection, climate change mitigation, and sustainable development. As part of both national and international legal frameworks, environmental law seeks to balance environmental preservation with economic and social needs, often through regulatory mechanisms, enforcement measures, and incentives for compliance.

The field emerged prominently in the mid-20th century as industrialization and environmental degradation spurred global awareness, culminating in landmark agreements like the 1972 Stockholm Conference and the 1992 Rio Declaration. Key principles include the precautionary principle, the polluter pays principle, and intergenerational equity. Modern environmental law intersects with human rights, international trade, and energy policy.

The Gulf of Drin or Bay of Drin (Albanian: Gjiri i Drinit or Pellgu i Drinit) is an ocean basin of the Adriatic Sea within the Mediterranean Sea along the northern coast of Albania. Roughly scythe-shaped, it extends immediately from the Delta of the Buna in the north, across the port city of Shëngjin, to the Cape of Rodon in the south. The shoreline of the gulf is a shallow combination of sandy beaches, sand dunes, capes, salty and fresh water wetlands, estuaries, pine and coastal forests, reed beds and coastal meadows.

The shoreline of the gulf has a length of approximately 60 kilometres and is dotted with cliffs and beaches fed by fluvial imputes. The region is drained by numerous rivers and has formed a characteristic ecosystem and biodiversity. It is named after the Drin River that runs through a mountainous area towards the coast, however, the Ishëm and Mat also drain into the gulf. In consideration to the flat landscape, the gulf's shoreline are dotted with extensive wetlands and lagoons that continuously change in size and shape.

The Volga (Russian: Волга, pronounced [ˈvoɫɡə] ) is the longest river in Europe and the longest endorheic basin river in the world. Situated in Russia, it flows through Central Russia to Southern Russia and into the Caspian Sea. The Volga has a length of 3,531 km (2,194 mi), and a catchment area of 1,360,000 km (530,000 sq mi). It is also Europe's largest river in terms of average discharge at delta – between 8,000 m/s (280,000 cu ft/s) and 8,500 m/s (300,000 cu ft/s) – and of drainage basin. It is widely regarded as the national river of Russia. The hypothetical old Russian state, the Rus' Khaganate, arose along the Volga c. 830 AD. Historically, the river served as an important meeting place of various Eurasian civilizations.

The river flows in Russia through forests, forest steppes and steppes. Five of the ten largest cities of Russia, including the nation's capital, Moscow, are located in the Volga's drainage basin. Because the Volga drains into the Caspian Sea, which is an endorheic body of water, the Volga does not naturally connect to any of the world's oceans.

The Black Forest (German: Schwarzwald [ˈʃvaʁtsvalt] ) is a large forested mountain range in the state of Baden-Württemberg in southwest Germany, bounded by the Rhine Valley to the west and south and close to the borders with France and Switzerland. It is the source of the Danube and Neckar rivers.

Its highest peak is the Feldberg with an elevation of 1,493 metres (4,898 ft) above sea level. Roughly oblong in shape, with a length of 160 kilometres (100 miles) and breadth of up to 50 km (30 mi), it has an area of about 6,009 km (2,320 sq mi).

In physical geography, a steppe (/stɛp/) is an ecoregion characterized by grassland plains without closed forests except near rivers and lakes.

Steppe biomes may include:

Hilversum (Dutch pronunciation: [ˈɦɪlvərsʏm] ) is a city and municipality in the province of North Holland, Netherlands. Located in the heart of the Gooi, it is the largest urban centre in that area. It is surrounded by heathland, woods, meadows, lakes and smaller towns. Hilversum is part of the Randstad, one of the largest conurbations in Europe, and the Amsterdam metropolitan area; it is about 22 km southeast of Amsterdam's city centre and about 15 km north of Utrecht.

The city is home to several major radio, television, and newspaper companies such as NOS. Hilversum is thus known for being the mediastad (media city) of the Netherlands.

The wood industry or timber industry (sometimes lumber industry – when referring mainly to sawed boards) is the industry concerned with forestry, logging, timber trade, and the production of primary forest products and wood products (e.g. furniture) and secondary products like wood pulp for the pulp and paper industry. Some of the largest producers are also among the biggest owners of forest. The wood industry has historically been and continues to be an important sector in many economies.

Downstate New York is a region that is generally described as consisting of the southeastern and more densely populated portion of the U.S. state of New York, in contrast to upstate New York, which comprises a larger geographic area with much sparser population distribution. While there is no widely agreed upon definition, the Downstate region is considered to consist of several subregions including New York City, Long Island, the Lower Hudson Valley and may also be considered by residents to include the Mid-Hudson Valley and Catskill Mountains areas. The New York State Department of Transportation (NYSDOT) defines its "Downstate Region" as including Dutchess and Orange counties, and the counties east and south of them in regions 8, 9 and 10 of the inset map. Both agencies and the general public use varying definitions of the boundary between Upstate and Downstate.

Despite being a small portion of the state's total land area, the Downstate region contains approximately two-thirds of New York's entire population. Its layout is largely urban and suburban, and constitutes New York State's portion of the New York metropolitan area, the world's largest urban landmass. New York City, the most populous city in the United States, is home to the United Nations headquarters, and has been described as the cultural, financial, and media capital of the world, as well as the world's most economically powerful city. The Upstate New York region, conversely, which forms the vast majority of the state's land area, contains more undeveloped land, including forests and farmland.

An old-growth forest or primary forest is a forest that has developed over a long period of time without disturbance. Due to this, old-growth forests exhibit unique ecological features. The Food and Agriculture Organization of the United Nations defines primary forests as naturally regenerated forests of native tree species where there are no clearly visible indications of human activity and the ecological processes are not significantly disturbed. One-third (34 percent) of the world's forests are primary forests. Old-growth features include diverse tree-related structures that provide diverse wildlife habitats that increases the biodiversity of the forested ecosystem. Virgin or first-growth forests are old-growth forests that have never been logged. The concept of diverse tree structure includes multi-layered canopies and canopy gaps, greatly varying tree heights and diameters, and diverse tree species and classes and sizes of woody debris.

As of 2020, the world has 1.11 billion ha (2.7 billion acres) of primary forest remaining. Combined, three countries (Brazil, Canada, and Russia) host more than half (61 percent) of the world's primary forest. The area of primary forest has decreased by 81 million ha (200 million acres) since 1990, but the rate of loss more than halved in 2010–2020 compared with the previous decade.

Greenhouse gas emissions from agriculture are large: the agriculture, forestry and land use sectors contribute between 13% and 21% of global greenhouse gas emissions. Direct greenhouse gas emissions include those from rice and livestock farming. Indirect emissions from the conversion of non-agricultural land such as forests into agricultural land are also very important. With regards to direct emissions, nitrous oxide and methane makeup over half of total greenhouse gas emissions from agriculture. A 2023 review emphasizes that emissions from agricultural soils are shaped by factors such as soil type, climate, and management practices. It also highlights several mitigation strategies, including conservation tillage, precision agriculture, improved water use, and the application of biochar, that can reduce emissions and enhance soil carbon storage.

Furthermore, there is also fossil fuel consumption for transport and fertilizer production. For example, the manufacture and use of nitrogen fertilizer contributes around 5% of all global greenhouse gas emissions. Livestock farming is a major source of greenhouse gas emissions.

A wildfire, forest fire, or a bushfire is an unplanned and uncontrolled fire in an area of combustible vegetation. Some natural forest ecosystems depend on wildfire. Modern forest management often engages in prescribed burns to mitigate fire risk and promote natural forest cycles. However, controlled burns can turn into wildfires by mistake.

Wildfires can be classified by cause of ignition, physical properties, combustible material present, and the effect of weather on the fire. Wildfire severity results from a combination of factors such as available fuels, physical setting, and weather. Climatic cycles with wet periods that create substantial fuels, followed by drought and heat, often precede severe wildfires. These cycles have been intensified by climate change, and can be exacerbated by curtailment of mitigation measures (such as budget or equipment funding), or sheer enormity of the event.

Montane ecosystems are found on the slopes of mountains. The alpine climate in these regions strongly affects the ecosystem because temperatures fall as elevation increases, causing the ecosystem to stratify. This stratification is a crucial factor in shaping plant community, biodiversity, metabolic processes and ecosystem dynamics for montane ecosystems. Dense montane forests are common at moderate elevations, due to moderate temperatures and high rainfall. At higher elevations, the climate is harsher, with lower temperatures and higher winds, preventing the growth of trees and causing the plant community to transition to montane grasslands and shrublands or alpine tundra. Due to the unique climate conditions of montane ecosystems, they contain increased numbers of endemic species. Montane ecosystems also exhibit variation in ecosystem services, which include carbon storage and water supply.

Mount Pinatubo is an active stratovolcano in the Zambales Mountains in Luzon in the Philippines. Located on the tripoint of Zambales, Tarlac and Pampanga provinces, most people were unaware of its eruptive history before the pre-eruption volcanic activity in early 1991. Dense forests, which supported a population of several thousand indigenous Aetas, heavily eroded and obscured Pinatubo.

Pinatubo is known for its VEI-6 eruption on June 15, 1991, the second-largest terrestrial eruption of the 20th century after the 1912 eruption of Novarupta in Alaska. The eruption coincided with Typhoon Yunya making landfall in the Philippines, which brought a dangerous mix of ash and rain to nearby towns and cities. Early predictions led to the evacuation of tens of thousands of people, saving many lives. The eruption severely damaged surrounding areas with pyroclastic surges, pyroclastic falls, and later, flooding lahars caused by rainwater re-mobilizing volcanic deposits. This destruction affected infrastructure and altered river systems for years. Minor dome-forming eruptions inside the caldera continued from 1992 to 1993.
