Why are mangroves in Pakistan under threat?
KARACHI: Due to lack of care, deforestation and a decrease in the flow of freshwater into the sea, the mangroves situated on Sindh’s coastal line are in danger, as the number of forests is gradually diminishing.

According to survey under Red Plus programme, the Azad Jammu and Kashmir has the highest forest cover at 36.9%, followed by Khyber Pakhtunkhwa (20.3%), Islamabad (22.6%) and Federally Administered Tribal Areas (19.5%).
What collects in a mangrove?
It’s not just trees but the land itself that increases. Mud collects around the tangled mangrove roots, and shallow mudflats build up. From the journey of a single seed a rich ecosystem may be born.

How do mangrove-vegetated shores prevent erosion?
Mangrove-vegetated shores reduced erosion rates from 3 to 15 times in the two sites with higher wave energy, while the vegetated site with the lowest wave energy experienced accretion compared to minor erosion along the unvegetated shore.
How do mangrove trees adapt to anaerobic and waterlogged conditions?
This suggests that mangrove trees can adapt to anaerobic and water-logged conditions by increasing their number of pneumatophores, hence providing greater surface area for gas exchange. In addition, there was a significant effect of mangrove (natural and planted), tidal position, and their interaction.
