Conifer forests have the simplest structure: a tree layer rising to about 98 feet (30 metres), a shrub layer that is spotty or even absent, and a ground layer covered with lichens, mosses, and liverworts.

Abstract The Earth was covered by approximately 14.8 billion acres of forest 8,000 years ago (Rainforest Alliance, 1999).

Temperatures are expected to rise another 4 to 8° F by mid-century - but there are actions we can take now to avoid the worst of these damages. The Tongass’ towering spruce-hemlock forests absorb fully some 8 percent of the nation’s carbon dioxide released as a byproduct of fossil fuel use. In doing so, the Tongass stores over ten times more carbon in its forests than any other national forest in the nation , e.g. Conserving Southern Longleaf: Herbert Stoddard and the Rise of Ecological Land Management (Environmental History and the American South Ser.)

Unfortunately, the world’s biocapacity—the amount of resources its ecosystems can supply each year—was only equivalent to 2.1 gha per person and is declining each year as population increases (see graph). The deficit between biocapacity and our ecological footprint causes damaging environmental changes to forests, fisheries, rivers, coral reefs, soil, water and air, and plays a major role in global climate change , cited: Steck-Vaughn Pair-It Books Proficiency Stage 6: Student Reader Ecosystems, Ecosystems Steck-Vaughn Pair-It Books Proficiency.

The camera takes overlapping photographs, and when viewed in pairs through a stereoscope, the terrain is seen in three dimensions and precise height and distance measurements can be made. Today this type of monitoring is being replaced by satellite monitoring which can cover far greater areas in a much shorter period of time.
