Wilderness or wildlands (usually in the plural), are natural environments on Earth that have not been significantly modified by human activity or any nonurbanized land not under extensive agricultural cultivation.

Xylophagy (is a term used in ecology to describe the habits of an herbivorous animal whose diet consists primarily (often solely) of wood. The word derives from Greek ξυλοφ?γος (xulophagos) "eating wood", from ξ?λον (xulon) "wood" and φαγε?ν (phagein) "to eat", an ancient Greek name for a kind of a worm-eating bird. Animals feeding only on dead wood are called sapro-xylophagous or saproxylic)

Young boreal forest

the goal is to achieve the optimal density of vegetation with the right species in the shortest possible time—and exceed reclamation standards

Anoxic waters are defined as those waters that have no dissolved oxygen (Richards 1965). This condition can occur in natural waters when the rate of consumption of oxygen exceeds the supply. The rate of oxidation of organic matter by bacteria is greater than the supply of oxygen from the atmosphere.

Biome (is a community of plants and animals that have common characteristics for the environment they exist in. They can be found over a range of continents. Biomes are distinct biological communities that have formed in response to a shared physical climate. Biome is a broader term than habitat; any biome can comprise a variety of habitats)

Chlorophyll's job in a plant is to absorb light—usually sunlight. ... The process of photosynthesis produces oxygen, which is released by the plant into the air. Chlorophyll gives plants their green color because it does not absorb the green wavelengths of white light.

Deforestation (is the removal of a forest or stand of trees from land which is then converted to a non-forest use. Deforestation can involve conversion of forest land to farms, ranches, or urban use. The most concentrated deforestation occurs in tropical rainforests. About 31% of Earth's land surface is covered by forests. Between 15 - 18 million hectares of forest, an area the size of Belgium are destroyed every year, on average 2,400 trees are cut down each minute)

Eutrophication,is when a body of water becomes overly enriched with minerals and nutrients which induce excessive growth of algae. This process may result in oxygen depletion of the water body after the bacterial degradation of the algae

Fire Ecology (is a scientific discipline concerned with natural processes involving fire in an ecosystem and the ecological effects, the interactions between fire and the abiotic and biotic components of an ecosystem, and the role as an ecosystem process. Many ecosystems, particularly prairie, savanna, chaparral and coniferous forests, have evolved with fire as an essential contributor to habitat vitality and renewal. Many plant species in fire-affected environments require fire to germinate, establish, or to reproduce. Wildfire suppression not only eliminates these species, but also the animals that depend upon them)
