Bamboo fence restores sand hills on the seashores

 ▲The sand collectors have been installed for the past 20 years in the Taean Seashore National Park to restore the sand dune damaged due to serious coastal erosion. 


On June 16th, the Korea National Park Service (KNPS), affiliated with the Ministry of Environment, announced the result of the sand collector installation project in the Taean Seashore National Park. According to the announcement, the coastal dune, equivalent to the size of nine soccer fields has been restored in the park. Across South Korea, 14 coastal dunes, including Gijipo, have been restored and 6.575ha of the habitat for plant species have been secured.

 

The KNPS has installed the sand collectors for the past 20 years in the Taean Seashore National Park to restore the sand dune damaged due to serious coastal erosion. A coastal dune is a mound of sand formed by the wind along the beach. Not only does it serve as a natural breakwater when typhoons or tsunamis hit, but it also has high ecological value as various creatures live in the sand dune. Erosion began in the Taean Seashore National Park during the 1970s and today, many parts of the sand dune have been destroyed. Furthermore, the direction of the waves has changed and the inflow of sediments from the rivers has decreased.

 

Facing this situation, the KNPS began the restoration project in 2001 with the installation of the sand collector which is now in 14 locations. The sand collector is made of bamboo to a height of 1.2m and is set up near the seashore. Sand blown by the wind is caught by the bamboo fence which acts as a shelter from the wind. Over the past 20 years collectors totaling 10.7 kilometers have been installed accumulating a total of 78,900㎥ of sand, the equivalent weight of 4,641 x 25-ton trucks.

 

Jung Seung-jun, head of the KNPS Maritime Resources Department said, “The land raised to the height of the coastal sand dunes, pulls the underground water level up and provides water necessary to people and many species to live.” He added that the sand of the coastal dunes creates a unique ecosystem. The KNPS is currently planning to restore a further 9,000㎡ of sand dunes this year in order to diversify plant species and improve the ecological function of carbon absorption.
