Coniferous forests are found in colder climates, in fact the further north you go the less deciduous trees you will find. This also holds true for hot climates. Coniferous trees have evolved needles and thick sap so they lose less moisture to the elements while deciduous trees are usually located in areas of abundant moisture.
