Participation in Tree-Planting Activity to Preserve Mangroves

Tree-planting in a mangrove forest

Hello, everyone. I’m Taguchi of Sumitomo Electric Wintec (Thailand) Co., Ltd.

Let me tell you about the tree-planting activity in a mangrove forest in which we participated on April 6, 2012.

Our company is located approximately 30 km southeast of Bangkok, specifically, near the seashore connecting the mouth of the Chao Phraya River and the Gulf of Thailand. Along this seashore extends a beautiful mangrove forest.

As you may know, a mangrove forest functions not only as something to mitigate the effect of waves rolling toward the seashore, but also as a nursery ground for creatures living along the seashore. Moreover, the forest absorbs CO2, contributing to the prevention of global warming. Thus, mangrove forests are gregarious forests essential to the earth.

In recent years, however, the destruction of mangrove forests due to logging is becoming a serious concern around the world.

With this as the background, an activity to plant and grow small saplings was launched to preserve a precious mangrove forest. From March to May every year, more than 100 companies located in our neighborhood participate in this activity.

On April 6, more than 70 people, comprising our staff members, including our president, and their families, participated in the tree-planting activity.

It was the hottest season in Thailand. With sunlight pouring down directly from above, the staff members went into the mudflat and carefully planted 1,500 Abyssinia shrub saplings. It took about two hours to plant all the saplings. Although the members got sweaty and tired, many of them said “I really enjoyed the tree-planting!” or “I feel refreshed!”

This was the first time to participate in this tree-planting activity. To contribute to the preservation of a mangrove forest invaluable to the earth, we will continue to participate in the activity again next year and beyond.

The Koya Pond Restoration Project

Located in Itami City, Hyogo Prefecture, Koya Pond is one of the Kansai region’s most popular stopovers for migratory birds. From autumn to winter, various water birds, such as wild ducks, arrive at the pond. In the middle of the pond is an artificial island in the shape of the Japanese archipelago. You can see the shape of the island out of a plane window immediately after taking off from Osaka International Airport.

Itami Works participates in the forest section of the local association for the protection of Itami’s natural environment. This association is working on a project to restore the natural environment of Koya Pond, which is adjacent to Itami Works. Since the works began to participate in the project, Mr. Miyake of the Safety & Environment Group of Itami Works has been serving as a coordinator to promote the project. He told us about the project.



Surrounded by a residential area, Itami Works aims to create an open environment. At the works, we invite members of the board of the residents’ association and other neighbors to the Inari Festival (April) and the Greenery-Floral Festival (November). We emphasize the improvement of mutual communication with the local community. We focus on mutual prosperity with the local community, not only by participating in the forest Section, but also by joining in local community clean-up activities, concluding a disaster management agreement with Itami City, among many other such efforts.

In April 2008, we began to support the project to restore the natural environment of Koya Pond. Every month, approximately six people from various group companies and divisions participate in an activity related to the project. In the last four years, a total of 282 people have participated in 49 activities.

The Association to Preserve and Grow the Nature of Itami was originally established to deal with the problem of saplings dying due to the droppings of great cormorants. The saplings on the artificial island (called the “Japanese Archipelago”), once rich in greenery, were seriously damaged, making it difficult to restore the saplings on their own. To help with the restoration of the green environment of the Japanese Archipelago, the association mainly promotes 1) picking seeds, 2) growing saplings, 3) planting the saplings on the Japanese Archipelago, 4) removing weeds, and 5) taking countermeasures against great cormorants. Of particular note is that the association does not purchase saplings available on the market but grows seeds from old trees in Itami and the surrounding mountains in order to restore plant species indigenous to Itami. The association is thus making long-term endeavors to improve the natural environment.

On March 27, a total of 28 people – 17 Itami residents, two from the Green Public Parks Division of Itami City, and nine from Itami Works – landed on the Japanese Archipelago, removed damaged saplings, added leaf mold to improve the soil, and planted approximately 40 deciduous trees, such as Swida. They also removed great cormorant nests and trimmed the branches of trees to prevent the birds from building new nests. While doing the work, which was unfamiliar to them, they held their heads back, causing a dull pain in their arms, back and neck. Moreover, since it was the great cormorants’ breeding season, many birds took up position on the trees of the Japanese Archipelago, giving off a more disgusting smell of droppings than usual. As shown in the photographs below, a mask was an essential item during the work, indicating how painstaking the work was. At the same time, they were able to enjoy one valuable experience. Although usually there is no other means than using a boat to reach the Japanese Archipelago, they were able to walk to the island from the neighboring shore; it was the season when the water level was low.

The growth rate of the saplings planted on the Japanese Archipelago is only around 50%, due to the soil quality, damage caused by the droppings of great cormorants, lack of sunlight due to weeds, which grow as tall as a person in summer, and other factors. However, Mr. Miyake said earnestly that Itami Works will continue supporting the activities of the Forest Committee to contribute to the restoration of Koya Pond with distinctive beauty of the four seasons. Now that the season of lush green has come, why not visit the Koya Pond Park?
