Small bites from the SAS guide

i was reading through my guide and i came across some very interesting stuff about climate. if you have the book then you might want to look in the second chapter (climate and terrain)

for those of you who don't have it I shall over the course of today try and get as much of the information in this up as possible.
Climate zones

polar
latitudes higher than 60 degrees 33' north ans south.

tundra
treeless zone south of the polar cap. the subsoil is permanently frozen (permafrost) and vegetation stunted

northern coniferous forest
found between Arctic tundra and temperate lands. winters long and severe.trees and plants flourish along the great rivers that flow to the artic ocean. elk, bear, squirrels and birds are plentiful. dense growth makes going difficult.

Deciduous forest
Oak beech maple and hickory are the main species in america. Oak beech chestnut and lime, in Eurasia. teh rich soil supports many plants. survival is easy, except in high altitudes where tundra or snowfield condition apply

temperate grassland
found in central continental areas of north america and eurasi. hot summers, cold winters and moderate rainfall have made these great food producing areas.

Mediterranean regions
lands bordering the med are semi-arid, with long hot summers and short dry winters. trees are few water is scarce

tropical rainforests
equatorial rainforests, subtropical rainforest and montane rainforest all feature high rain fall and rugged mountains, which drain into large swift flowing rivers, with coastal and low lying regions as swamp land.

savannah
tropical grassland found in Australia, Venezuela, Columbia, Brazil and Africa. grass grows up to 3m (10ft). temperatures are high all year round. water is scarce, but where it is found there will be lush vegetation and plenty of wildlife.

desert
one-fifth of the earths land surface is desert of which only small parts are sand most is flat gravel cut by dried up water courses. very high temperatures occur by day, falling to below freezing at night. survival is difficult.

tropical regions
everything in a jungle thrives,including disease and parasites. even if saturated by perspiration, clothing affords protection from stings and bites.
except at high altitudes, equatorial and subtropical regions are characterised by high temperatures, heavy rainfall and oppressive humidity. violent storms may occur towards then end of summer. in choosing camp sites make sur you are above potential flooding.

equatorial rainforest
temperatures range from 30 degrees c to 20 degrees c at night. jungle trees rise from buttress roots to 60m (179ft). in this primary jungle the canopy prevents light reaching the jungle floor. it is relatively cool, with little undergrowth to hamper movement, but visibility is limited. it is easy to lose a sense of direction and difficult for rescuers to follow you.

secondary jungle
along river banks and the fringes of the jungle sunlight does penetrate to the floor and growth is prolific. undergrowth reaches heights of 3m in a year. moving is slow hot work, hacking away with a parang or machete

sub-tropical rainforests
found within 10 degrees of the equator, these forests have a season of reduced rainfall, even drought, with monsoons coming in cycles. more deciduous trees grow here and undergrowth is dense

fire
everything is likely to be damp. take standing dead wood, shave off outside and use to start your fire. dry bamboo and termites nests make good tinder.

like i said earlier there is more but my parents are on my back atm so ill try as much as i can to post!

if everything seems negative it is meant to be, it is telling you about all the dangers and stuff in the area. then later on it tells you how to overcome certain adverse situations
