The area of ​​the mountains that became ashes in this forest fire is larger than the sum of 740 soccer fields. How much time do you need to return to the beautiful original look.

Kim Jung-woo visited the 1996 Gangwon-do highland forest fire area, which had already happened more than 20 years ago.

Gangwon-do, which burned 3,700 hectares in 1996, has a long history of more than 20 years of sadness at Sampo, where all the towns have become ashes except one house.

The trees still stand with blackened scorched grass, and the animals left behind during the fires are still not returning.

[Yogi] / Goseong-gun Sampori residents: I do not get a mushroom on fire now. There were a few rabbits and pheasants around. Now, those things have been hidden.]

We have newly planted trees but the rate of forest restoration is about 70 ~ 80%.

It is a wild mountain of the Goseong-gun where a large wildfire occurred 20 years ago. As you can see, the beautiful pine trees are all around, but they are lined with tall pine trees.

Even though the trees grow bigger and have the appearance of the forest, it takes a long time to find the changed ecosystem.

[Kang, Won-seok / National Forestry Research Institute: If you see the inside of the bush, the function or the growth of trees in the forest is insufficient.]

The National Forestry Academy surveyed the forest fire area for 20 years and found that 13 years for insects such as ants, 35 years for wildlife, and 100 years for soils can be recovered.

In 2005, it took three years to plant trees in the Yangyang forest fires, which were about 1,000 hectares.
