These develop from a lake or flat marshy area, over either non-acidic or acidic substrates. Over centuries there is a progression from open lake, to a marsh, to a fen (or on acidic substrates, valley bog), to a carr, as silt or peat accumulates within the lake. Eventually, peat builds up to a level where the land surface is too flat for ground or surface water to reach the center of the …

forest, complex ecological system in which trees are the dominant life-form. Forests can occur wherever the temperatures rise above 10 °C (50 °F) in the warmest months and the annual precipitation is more than 200 mm (8 inches). They can develop under a variety of conditions within these climatic limits, and the kind of soil, plant, and animal life differs according to the …

Diana Gibson of the Parkland Institute, an environmental advocacy group, says that ...

and changes in climate and land use. Boreal forests and northern peatlands, which store nearly half the total terrestrial carbon in North America, are already experiencing substantial warming, resulting in large-scale thawing of permafrost and dramatic changes in aquatic and forest ecosystems. USGS scientists have estimated

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 …

The appropriate guide and form is determined by the natural region in which the wetland(s) is located. If the project is on the border of two natural regions, the Boreal-Foothills tool should be used if the majority of wetlands are peatlands and the Parkland-Grassland tool should be used if the majority of wetlands are mineral wetlands.

1.5°C pathway See Pathways.. 1.5°C warmer worlds Projected worlds in which global warming has reached and, unless otherwise indicated, been limited to 1.5°C above pre-industrial levels. There is no single 1.5°C warmer world, and projections of 1.5°C warmer worlds look different depending on whether it is considered on a near-term transient trajectory or at climate …
