Tropical rainforests have been called the "jewels of the Earth" and the "world's largest pharmacy", because over one quarter of natural medicines have been discovered there. [2] Rainforests as well as endemic rainforest species are rapidly disappearing due to deforestation, the resulting habitat loss and pollution of the atmosphere. [3]
Emergent layer exists in a tropical rain forest and is composed of a few scattered trees that tower over the canopy. [39] In botany and countries like Germany and Poland, a different classification of forest vegetation is often used: tree, shrub, herb, and moss layers (see stratification (vegetation)).
By communicating with the local people living in, and around, the rainforest, conservationists can learn more about what might allow them to best focus their efforts. [1] Rainforests are globally important to sustainability and preservation of biodiversity.
Conservation Education dealt with the natural world in a drastically different way from Nature Study because it focused on rigorous scientific training rather than natural history. [27] Conservation Education was a major scientific management and planning tool that helped solve social, economic, and environmental problems during this time period.
These rainforests are renowned for their significant biodiversity. They are home to 40–75% of all species globally, including half of the world's animal and plant species, and two-thirds of all flowering plant species. Their dense insect population and variety of trees and higher plants are notable. Described as the "world's largest pharmacy ...
Forest ecology shares characteristics and methodological approaches with other areas of terrestrial plant ecology, however, the presence of trees makes forest ecosystems and their study unique in numerous ways due to the potential for a wide variety of forest structures created by the uniquely large size and height of trees compared with other ...
The Appalachian temperate rainforest has a cool and mild climate and meets the criteria of temperate rainforests identified by Alaback. [1] Temperature and precipitation are extremely variable with elevation, with rainforest conditions usually but not always concentrated around spruce–fir forests at higher elevations.
The Canadian Organization for Tropical Education and Rainforest Conservation was founded in 1991 to protect tropical rainforests. [3] The board of directors comprises biologists, accountants, educators, environmentalists, zoo professionals, and media professionals operating in both Canada and Costa Rica. [4]
