Nitrogen saturation and net ecosystem production. The soil is then disked, fertilized, and planted with the commercial forage grasses Brachiaria humidicola or B. brizantha.

Rainforests are dense forests of tall trees in a region of year-round rainfall and warmth. Positive effects of tree diversity on above-ground productivity are certainly not an universal pattern, however [ 61, 66 ], and above-ground biomass production and soil carbon fixation may also respond differently to tree diversity in plantation forests [ 67 ].

The program is designed to educate volunteers in general eagle nesting biology, applicable laws, the identification of nest threats, monitoring techniques, and the verification of previously unrecorded active eagle nests. That same hectare, cleared of forest, can lose up to 34 tons of topsoil per year. The Penan of Sarawak, hunter-gatherers who harvest wild meat and a few minor forest products for their own use, are now building blockades to halt the timber trucks of the companies that are destroying their traditional lands.

They pay the price in extra nectar and larger flowers but in exchange they get a pollinator that can fly much further to seek out another plant of the same species. Between 1972 and 1980, 430 000 ha year−1 were cleared around the state ( Reed 1990 ), with rates subsequently (post-1986) varying between 20 000 and 80 000 ha year−1 within the eastern/central and western regions, respectively ( Norton 1996 ). Any major decline in the health of the Amazon rainforest is likely to impact the world climate.

As solar orbiting forcing gradually shifted, the climate in much of West and Central Africa shifted to a drier regime around 4000–2000 years BP [ 12 ]. They are rarely seen flying over the canopy or in open spaces. RATH / WWF-CANON 21 The leafcutter ant climbs tall trees to collect green leaves to grow fungus that they can eat. This earliest vegetation is soon (on the scale of 5-10 years) replaced by vegetation somewhat like that of the original forest, and this in turn by a forest with a species composition almost identical to the original.

A biome is a large, distinctive complex of plant communities created and maintained by climate.

Although there is only an incomplete understanding of the relationship between carbon sequestration and tree species and among carbon sequestration, forest management, and disturbance, some tree species require more carbon than others during growth, usually grow slowly, and ultimately store more carbon for a long period (e.g., Bunker et al. 2005, Vieira et al. 2005, Russell et al. 2010, Sharma et al. 2010).

Although forests worldwide play a key role in storing carbon and releasing oxygen, rain forests alone are not the earth s lungs, and it is very doubtful if replacing them with agriculture and plantations would have a major effect on the all-impoi-tant oxygen cycle.

Lucia's Atlantic Coast offers several scenic views on a mile-long trail circling the national park.

Tropical rainforests are a natural reservoir of genetic diversity which offers a rich source of medicinal plants, high-yield foods, and a myriad of other useful forest products. This is what the remaining pages of this book set out to do. Deforestation accounts for 12 to 20% of the global greenhouse gas emissions that contribute to global warming. The vast majority of other organic substances, such as potassium are also recycled in this manner, thus allowing ecosystems to survive without a constant influx of new organisms or nutrients.

With this in mind, it is remarkable that a large expanse of unlogged forest with three intact watersheds exists in the Siuslaw National Forest. The Sequoia National Forest covers 4,829 sq km (1,865 sq mi) 3. Because of the well-known environmental problems associated with the introduction of exotic species, plantation managers should select species carefully. The overly aggressive industrial culture which has led our planet to the brink of catastrophe must certainly undergo radical changes, but this in no way implies that industrial unionism should disappear.
