Vietnam
==== Average Temperature's of Vietnam is between 22°C to 27°C, and it get about 1500cm of precipitation. Bring Waterproof clothes, boots, and socks. A large quantity of socks is usually desirable. It is a wet land and if we were caught in the rain being dry is severely important.

The soils of Vietnam is rich but unfortunately has been corrupted by pollutants and wastes.

__Animals of Vietnam__
The Javan rhinoceros ("rhino") weighs 3200 - 4400 lb and has a length of 10 - 11'. The Javan Rhinoceros has survived in vietnam because it isnt limited to a certain area or land, it prefers the lowland and mudflats but can also be find in the highland and grassy hills of Vietnam. Also its nocturnal and diurnal, meaning it has a varied sleep track so that it can be active during the day, and during the night.



_ __The walking catfish 30.5 cm (12 in)__ capable of moving on land and, when it does so, is able to breathe air. It belongs to the family Clariidae, whose members have additional, specialized breathing organs opening off the gill arches. These are saclike structures containing many-branched extensions, well supplied with blood vessels for respiration. An elongate fish, this catfish has long-based dorsal and anal fins and several pairs of sensory barbels; its skin is scaleless but liberally supplied with mucus, which protects the fish when it is out of water. These catfishes live in ponds or temporary pools, some of which may disappear in prolonged dry spells. When this happens, the catfish can move overland to another body of water, making snakelike movements and using its pectoral fins as "legs." If necessary, the walking catfish can bury itself in mud at the bottom of a pond and remain dormant throughout a dry season until the rains return. It feeds on aquatic invertebrates and fish.



_ The Siamese fightingfish 6 cm (2 1/4 in) Well known for their aggressive nature, male fightingfish are kept in captivity to take part in staged fights. In natural conditions, however, the fishes fight for dominance or to maintain territory, but much of the contest takes the form of ritualized threat displays, rather than actual combat. The fishes adopt postures, extending their fins and raising their gill covers, one of them usually submitting before an actual fight becomes necessary. Like many members of the Belontiidae family, to which it belongs, the Siamese fightingfish often lives in stagnant, oxygen-poor water. It is able to take in air at the surface, however, using auxilliary breathing organs within its gill chambers. Mosquito larvae, as well as other aquatic insects, are the main diet of the Siamese fightingfishes, which are consequently extremely important as controllers of these insect pests. In the breeding season, the male fish selects a suitable nest site and blows a bubble nest from air and mucus, which both protects the eggs and keeps them at the well-oxygenated water surface. As the eggs are shed, they are fertilized by the male, who spits them into the nest. The male guards the nest and replaces the bubbles if necessary.weeks.

Mangrove Tree Mangrove trees grow where no tree has grown before. They are able to survive inundation by salt water twice a day, and in soil which is unstable and poor in oxygen. They also have to deal with swollen rivers carrying silt during the wet season, as well as violent storms that hit the coasts. To deal with salt, all mangrove trees exclude some salt at the root level, and all can tolerate more salt in their tissues than normal plants, often in quantities that would kill other plants.



_ __Pickerel Weed__ Pickerel weed is a perennial plant that can grow up to 3 1/2 feet tall. Leaves are shiny green, heart-to-lance shaped(up to 7 inches long) singly attached to a long petiole which grow in a rosette from the roots. Each stem can produce a terminal flower spike 3 to 4 inches long. The numerous tubular flowers on the spike are violet-blue in color. Each flower lasts only one day. Pickerel weed reproduces from seeds and rhizomes.



__Human Activity in Vietnam__
Because of constant flooding you will notice most houses are built up on stilts. Also because of all of the water ways boats are a primary means of transportation.

=Environmental Issues= Flooding is a big problem in Vietnam. Its caused by constant rain fall that can last for weeks.
