Mangrove swamps are common on the coasts.
The mangrove grows on the shores of the west coast in profusion.
Great mangrove swamps supply unlimited fire-wood of the best quality.
The mangrove swamps at the north-west end of the harbour have been drained and partially built over.
Vegetation of all sorts acts in a similar way, either in forming soil and assisting in breaking up rocks, in filling up shallow lakes, and even, like the mangrove, in reclaiming wide stretches of land from the sea.
There are undrained, swampy districts in Campeche, in the vicinity of the Terminos Lagoon, where malarial diseases are prevalent, and the same conditions prevail along the coast where mangrove swamps are found.
Mangrove swamps, lagoons and marshes, with inland canals following the coast line for long distances, are characteristic features of a large extent of the Brazilian coast.
They then become low and are fringed with mangrove swamps.
Coco-nut palm, banana, Jamaica dogwood, manchineel and mangrove; the Tropical belt in the lower valley of the Colorado has giant cactuses.
The sea-coast, bays and tide-water rivers are still fringed with mangrove, and on the sandy shores above Cape Frio grow large numbers of the exotic cocoa-nut palm.
The coast and tide-water rivers are fringed with mangrove, and the sandy plain reaching back to the margin of the inland plateau is generally bare of vegetation, though the carnahuba palm (Copernicia cerifera) and some species of low-growing trees are to be found in many places.
Though a species of mangrove fringes much of this peninsula, its presence does not denote malaria, from which the islands are entirely free.
The mangrove is the characteristic tree of the swamps.
Turtle are common on the southern coast-line, sand and mangrove oysters are plentiful.
The flora resembles that of West Africa generally, the mangrove being common.
In the coast regions the typical tree is the mangrove, which flourishes wherever the soil is of a swamp character.
On both the east and the west coast the islands are thickly wooded, but whereas the former are surrounded by beautiful sands and beaches, the latter are fringed by mangrove-swamps.
The coasts of the Andamans are deeply indented, giving existence to a number of safe harbours and tidal creeks, which are often surrounded by mangrove swamps.
Dense scrub covers most of the land, but the inner (lagoon) shore is everywhere bounded by mangrove swamps.
But the most striking of the coast-belt flora are the tropical forms - the palm, mangrove, wild banana (Strelitzia augusta), tree-ferns, tree euphorbia, candelabra spurge and Caput medusae.
The principal exports from Maracaibo are coffee, hides and skins, cabinet and dye-woods, cocoa, and mangrove bark, to which may be added dividivi, sugar, copaiba, gamela and hemp straw for paper-making, and fruits.
After passing the mangrove limits, the ground to the east gradually rises till it becomes mountainous, even to the banks of the rivers, and finally culminates in the grand natural barrier dividing Burma from Siam.
On the low littoral zone the coast produced a rich tropical bush, in which the mangrove is very prominent.
Then, there are the mangrove-fringed coasts and the dripping wooded slopes where rare orchids thrive, and above these, on the inland side of the sierra, a treeless, sun-scorched table-land where only the cactus, yucca, and other coarse vegetation of the desert can thrive without irrigation.
The coast is generally so low as to be visible to navigators only within a very short distance, the mangrove trees being their only sailing marks.
Inland, a network of interlacing creeks and broad sluggish channels fringed with monotonous mangrove forests.
The Guayas or Guayaquil river is in part an estuary extending northward from the Gulf of Guayaquil, bordered by mangrove swamps and mud banks formed by the silt brought down from the neighbouring mountains.
For instance, Guayaquil has a hot humid climate and mangrove swamps line the shores of Guayas down to the gulf; at Santa Elena, about 60 m.
Characteristic of this region are the mangrove and Pandanus, and, a little inland, the banyan (Ficus), Pisonia and Hernandia.
Owing to increased competition, and in some degree to careless harvesting, there was a great fall in prices after 1900, and the Seychellois, though still producing vanilla in large quantities, paid greater attention to the products of the coconut palm - copra, soap, coco-nut oil and coco-nuts - to the development of the mangrove bark industry, the collection of guano, the cultivation of rubber trees, the preparation of banana flour, the growing of sugar canes, and the distillation of rum and essential oils.
The coast is low, intersected by creeks, and forms one huge mangrove swamp; on the rising ground inland are dense forests in which the cotton and mahogany trees are conspicuous.
And has a white spathe more than a foot in length; and on the western coast dense thickets of mangrove line the creeks and rivers.
We thus obtain the following four main divisions of the continent: - (1) The coast plains - often fringed seawards by mangrove swamps - never stretching far from the coast, except on the lower courses of streams. Recent alluvial flats are found chiefly in the delta of the more important rivers.
The west coast throughout its whole length is covered to a depth of some miles with mangrove swamps, with only a few isolated stretches of sandy beach, the dim foliage of the mangroves and the hideous mud flats presenting a depressing spectacle.
Mangrove swamps surround the town and epidemics of cholera, yellow fever and other tropical diseases have been frequent; but the unhealthiness of the climate is mitigated to some extent by the high tides which cover the marshes, and the invigorating breezes which blow in from the sea.
Southwards of Mergui town it consists chiefly of low mangrove swamps alternating with small fertile rice plains.
There are some low, swampy islands, or mud flats, covered with mangrove thickets, in the lower Guayas river, but they are uninhabited and of no importance.
Gutta, rubber, rattans, mangrove-bark, edible nuts, guano, edible birds'-nests, &c., are all valuable articles of export.
The western coast has fewer and shorter off-shore reefs; much of it is of minutely irregular outline, which seems to be determined less by the work of the sea than by the forward growth of mangrove swamps in the shallow salt water.
