Freshwater Wetland Ecosystem of Pakistan – Climatic Biome

freshwater wetlands hold biodiversity

INTRODUCTION

Freshwater Wetland Biome: It is defined as a diverse variety of areas where the wet soil is covered with standing water. Wetlands are not Estuaries because wetlands don’t have openings to oceans. The rainwater filling up a large shallow hole in the ground is often considered a wetland biome.

Characteristics of Freshwater Wetland Biome: A freshwater wetland biome is a region that holds water below 1% salt concentration and diverse species of animals and plants.

FRESHWATER WETLAND BIOME OF PAKISTAN

Freshwater wetland biome is found everywhere on the Earth that includes streams, ponds, rivers, lakes, rice paddies, etc.

Location of Freshwater Wetland Biome of Pakistan: It is present nearly in every province of Pakistan including Punjab, Sindh, Khyber Pakhtunkhwa, Baluchistan, Azad Jammu Kashmir and Gilgit Baltistan.

The major wetland complexes in Pakistan are

  • North Western Alpine wetland complex – Northern Areas
  • Salt Range Wetland Complex – Punjab
  • Central Indus Plain Wetland Complex – Punjab, Sindh,
  • Makran Coast Wetland complex – Baluchistan
  • Jiwani Wetland Complex – Baluchistan
  • Deh Akro-II Desert Wetland Complex – Sindh

The recorded precipitation ranges from 300 to 800mm. The highest temperature ranges 36-41 °C during summers and the lowest temperature is 0.5-4 °C.
