 So 1950 this area there was a military base and there was a big war 1950 to 1953 which is the Korean War yes after that time we we started reforestating this area so at that time it was a bare land like this as you see here and then we make the wind breaking system and we we had we we did restoration you see also we plant the trees not only but we make the wind breaking system here the 1950s they made these bunkers and the the military was here it was a very big underground bunker and 2007 27th of April 47 days it took us to remove the bunker and this area was strictly restricted area for normal people so you see the small trees to your right side and to your left side these are about 20 year old we planted at the 90s and then 2000s we have a very big mountain here in Korea this area the plantation was this high they all cut it for us they had cut it last week so we can come up easier yes thank you and then these trees were originally like the wind breakers now the trees are big enough so we don't need it anymore but originally when we plant the small vegetation we need this wind breaking if not the roots will keep on shaking and then it will dry it will dry and it will die so not only the wind breaking system we use but we also use something like supports like this every year after you plant a tree every every year until five year we plant the tree we have to cut the small vegetations because sometimes the vegetation is winning the tree but this tree must get the sun alone that is why for five years we do that and then afterwards okay let's say five years past so there is one tree another tree another tree very beautiful but sometimes the natural seeds come and then growing different different kind of tree then we pick that also if okay there was 100 trees here but maybe five died only 95 survived then we kill this five five tree already dead we have to get rid of that we do a maintenance five year to 10 year okay so it is like this what we do after 10 years the tree is now big yeah then what we do is we want this tree to grow thick and high then in between the 95 trees which survived we can cut maybe 20 to 30 percent of the trees we cut it down because the other trees must grow thicker and bigger yeah yes this area which you can see in uh like orangeish color no what is the brownish color this area is all special plantation area so this area there were farmers here that they used to burn the woods and do farming but the korean government made a law saying there can be nobody living inside the mountain so the government moved all the houses inside this area and this area was a bare land there was no uh it was the deforested land so and then afterwards we made a plan to reforestate here starting from 76 until to 86 for 11 for 10 and 11 years it took us uh first first uh re re reforestation plan it is 618 hectares in total and then we have 311 hectare was uh man planted which is uh especially we planted in this area and then the other other places were natural forest the first year when we started the reforestation in this area at the 1975 we had failed because we did not prepare for the wind but next year at the 1976 we started planting in this area with special care so wind breaking system and supporting trees then we had succeeded when you look at the end of the when you look at here you get look at this we call this installation protective net so this kind of net there is the tree inside here and then around we make a protection so here not only we give them fertilizers every year but we also have to cut the plantations like the grasses here or so and then we do mowing and it is all written on inside your page okay supplement planting and tending the young trees tending the young trees and removing uh creepers and heening or so we do this kind of uh projects inside here look at look at this here this is the peak of that mountain these are the trees that we had planted in this area now we go there and then this is 2011 how the trees grew and now it's this big
