How Mangrove Trees Survive in Saltwater?

Pakistan is home to the fifth-largest mangrove ecosystem in the world. Mangroves have a significant impact on the coastal region of Pakistan. 

Saltwater makes most of the trees easily damaged or killed, but mechanisms have evolved in mangroves that enable these trees to thrive in it. The internal tissues of mangroves exhibit a high tolerance to salt, but their roots function as filters, straining most of the salt out of the water they absorb. Excess salt is carried to the leaves and excreted onto their surfaces.

Conservation And Sustainable Development Of Mangroves Forest 

Because of severe damage to the coastal ecosystem of Pakistan, it needs to be addressed promptly. Following dams and barrages, there is a low water discharge from the river into the sea. It has reduced the quantity of silt brought from the mountains and plains. Along with fresh water, this silt contributes to the expansion of the delta and the growth of the mangroves. And also the marine habitats. Besides, the mangrove forest resource has been vanishing fast due to certain factors, like:

  • Mangroves cutting for fodder and firewood,
  • Seawater pollution
  • The removal of sand from the beaches
  • The reclamation of beaches for constructing buildings and roads.

All the above factors have become an added threat to Pakistan’s coasts. As a result, a healthy environment is crucial to growth. The health of marine resources has also been vanishing fast. Moreover, fishing communities experience the worst disaster when tropical cyclones hit coastal areas. Tidal waves and rainstorms knock down their shanty homes, destroying their belongings. If the coast had been fringed with mangroves, the loss could have been reduced.

Mangroves provide a nursery for shrimps, crabs, and several species. Mangrove leaves and twigs provide a fertile and beautiful habitat for the estuaries (an arm of the sea at the mouth of the river). Fishes and shrimps are nursed in these estuaries. The mangrove also produced honey from the blossoms of the Avicenna marina species, consisting of 95% of the mangroves lining our coasts.
