Haqqi Daulay's story about Research Forestry In Kang-Won Province South Korea and How to Simply Inventory of the Forest (Hutan Penelitian di Provinsi Kang- Won, Korea Selatan dan Bagaimana Cara Sederhana Menginventarisasi Hutan)

Forest Inventory on June, 29 2012 @ Research Forest Hong-Cheon. College of Forest and Environmental Sciences, Kang-Won Province, South Korea By: Haqqi Annazili

Today, we start our activity as usual, at 09.00 a.m. The lecturer today is Prof. Jung Kee CHOI. He met us at Cafetaria near the gate of Kangwon National University. As usual, He look like so cheerful, so kindly and very friendly although he is a big leader in this campuss. He asked us to entered the school bus that brought us to research forest of KNU in Hong-Cheon. I enjoyed the travel and asked my friend beside me about this place. I guess about 40 minutes we arrived at the site. We entered the 3th stage of the room meeting and got the explainations from Prof. Jung Kee CHOI. Mr. Jung Kee CHOI was very spirit that morning. He told about thus forest research, location, area, characteristics, forest equipment, forest measurements, and forest inventory in 80 years Korean White Pine Plantation ( Pinus koraenensis).

This research forest of KNU is very sustainable. I am very fortunate to entered the oldest forest Pinus Koraenensis in South Korea. At this time, this Pinus Koraenensis stands was eighty years old. This stand is a stand that was built before the independence of South Korea. South Korean society is very concerned about the forest. After gaining independence and after the Korean war, they planted many vacant lands, especially in the hills. Although the majority of the land here is not as green as the soil in tropical zones, but their spirit has resulted. At first glance, when viewed from the canopy, the majority of forests in South Korea is almost as green as the forest in tropical forest. Expanse of forest in each hill adorned South Korea, especially in Kang-Won Province.

Hong-Cheon research forest serves as a research site, area businesses, places of education, a model of sustainable forest management, and others. Total forest area is 3.146 ha of this study is divided into 33 compartments. Therefore, forest management here is divided into several compartments and sub-compartments.

White pine (Pinus Koraenensis) are native / locally species in South Korea. Region where the growth is temperate deciduous forest in the central zone. With soil conditions Granite, Granite gneiss / loam, loam Sand. In this educational forest, there are 177,4 hectares of stands of Pinus Koraennsis 80-year-old. Growing stock per hectare in this area is about 160 m3/ha. Besides Pinus Koraenensis, in this forest there are also Leplolepis larix, Pinus densiflora, Abies holophyta, and others. As I mentioned earlier, I think this educational forest really is so ideal, because of timber harvesting activities conducted in this area is also performing well. Harvesting in this area carried out with the help of forwarder, winch, and yader.

In forest measurements we found dbh, total height, basal area, and volume. The high breast height of every people are different, so in Korea we used 120 cm, but in the other country like in Indonesia and China are 130 cm. To measure the height, could use a clinometer, walking stick, and Suunto clinometers / Suunto tandem. On this project we use a Suunto clinometer. In Indonesia, I was used to conduct activities in forest inventory, but if a foreign person, this is my first experience, so many languages ​​are heard in the 20m x 20 m plot that we make. South Korean language most often I hear, that’s very beautiful, and the most word I like is the “hamsa hammida”. How to measure tree height using a suunto clinometers is, ensure your eyes are right into the hole suunto clinometers and left eye to see the top of the tree canopy and base. When measuring the maximum height, I am directing this tool to the top of the tree canopy and at the height measuring at least I pointed it at the base of the tree. Once it is inserted into the formula,

high tree = [(maximum height) - (minimum height)] x Distance holder suunto to a tree
                                                                        100
It will get the tree height in meters.

To measure the area (basal area), we use the formula for the cone shape because of the tree is not cylindrical. To measure the volume, we use the formula area of ​​the base multiplied by height, then converted into units of cubic meters per hectare. The price of a cubic meter of wood Pinus koraenensis in South Korea is $ 100, -. We get very accurate results with measurements taken several professors in South Korea is one acre generates about $ 30,000, -. So all of  Pinus Koraenensis in this region will result in (177 ha x $ 30,000, -) = $ 5,310,000, - . It is equivalent of IDR 47,79 billion or KRW 5, 49 billion.

The equipment to be possessed by a forester when go to forest such as helmet, orange vest, tally sheet, calculator, volume table, etc., because the forest is full of risks, so victory loves preparation.

Although physical activity these days are very tiring, which was climb the mountain with an average elevation of 45 degrees for about an hour and take inventory of the forest, but this activity was very memorable, because we also sing the song “Cikulele Hawaian Forester”, thank you very much for my Professor Jung Kee CHOI, my friend Gloria Kang, Yeon - wook, Nami Yun, Jeremy Azurin, and many more my very kind friends.
