Many migratory birds and butterflies spend winter in tropical and subtropical conifer forests. This biome features a thick, closed canopy which blocks light to the floor and allows little underbrush. As a result, the ground is often covered with fungi and ferns. Shrubs and small trees compose a diverse understory. [1]
The trees found in the third layer include young trees trying to grow into the larger canopy trees, and "palmoids" or "Corner Model Trees". The fourth layer is the shrub layer beneath the tree canopy. This layer is mainly populated by sapling trees, shrubs, and seedlings. The fifth and final layer is the herb layer which is the forest floor.

Mangrove forests, also called mangrove swamps or mangals, are found in tropical and subtropical tidal areas. Areas where mangroves occur include estuaries and marine shorelines. [19] The intertidal existence to which these trees are adapted represents the major limitation to the number of species able to thrive in their habitat. High tide ...
About half of the world's tropical rainforests are in the South American countries of Brazil and Peru. Rainforests now cover less than 6% of Earth's land surface. Scientists estimate that more than half of all the world's plant and animal species live in tropical rainforests.
[1] [2] Because of these difficulties, information on the extent of tropical forests varies between sources. However, tropical forests are extensive, making up just under half the world's forests. [3] The tropical domain has the largest proportion of the world's forests (45 percent), followed by the boreal, temperate and subtropical domains. [4]
The natural cover of India varies with altitude; these evergreen forests are bounded with high alpine meadows nearer to the snowline and temperate forests of short stout trees at lower elevations. In the Himalayan foothills are deciduous trees, with shrubs, bamboo, ferns and grass.The trees here are tall with harwood and broad leaves. The trees ...
Tropical ecology is the study of the relationships between the biotic and abiotic components of the tropics, or the area of the Earth that lies between the Tropic of Cancer and the Tropic of Capricorn (23.4378° N and 23.4378° S, respectively). The tropical climate experiences hot, humid weather and rainfall year-round.
