Describe the main features of Alpine, Coniferous, Riverine and Mangrove forests of Pakistan.

The alpine biome is characterized by unfavorable conditions for plants to thrive, including strong winds, unfavorably low temperatures, low carbon dioxide levels, and strong sunlight. With low carbon dioxide, plants have a hard time carrying out photosynthesis.Some basic characteristics of riverine or lotic (flowing, moving) systems include:  

unidirectional flowing water (downhill)

erosion and downstream transportation and deposition of sediments

links to floodplains

linear change in morphology and ecology

catchments made up of branching network of streams and rivers that are in dynamic equilibrium with the landscape and its...

catchments connect the landscape and the sea.

The main characteristics of mangrove forests:  

The root of the trees develop stilt-like aerial to suck oxygen.

The trees species can tolerate highly salt concentrated water.

The root of the trees remain submerged underwater.
