Do not cut the original forest, the development of Acacia wood industry is the best choice! The mountain forests of the whole island look for excellent mother trees and cultivate elite Acacia soldiers.

Although some people in the forest industry have interpreted the material characteristics of Acacia trees brilliantly, the impression that people think that Acacia trees are "crooked" is not valuable remains to be changed. In 2015, when Zhang Sen, a forestry professor at Louisiana State University, returned home for several explorations and advocated using acacia trees to dominate Taiwan's forestry, he scared a group of forestry experts. They thought to themselves, as far as they can see, the original Acacia tree grows crooked, how is it possible to do great things?

Zhang Sen specializes in forestry economics, and when the Forestry Bureau of the Council of Agriculture invited him to teach a course on seed collection and breeding of Acacia trees, he even announced in class that if he could find a "straight and perfect" Acacia tree, he would give him 500 yuan. This proposal is supported by the Forestry Bureau. through the plan, the Forest examination Institute will search the mountains all over Taiwan and gradually identify more than 200 handsome and straight Acacia trees as mother trees, so as to breed Taiwan's new forestry with global competitiveness.

Even if it is easy to collapse, it is not difficult to be independent and affectionate, only for those who set their minds to it.

Although it is the dry season in winter, the Zhuoshui Creek under the Sun Hai Bridge in Dandalin Road still makes a loud sound of water. During the rest and recuperation of the cages originally used to cross the bridge, the official car of the forest test station can only drive through the bridge body which is not much wider than the body of the car. I saw that the driver moved forward carefully and bumpy, and the conversation on the car was silent, and it was not until Enron Bridge that the discussion began again. Toil along the rugged mountain road, just to catch a glimpse of the high-quality acacia mother trees.

Getting off next to the Dandalin class, which is more than 700 meters above sea level, Zhang Bin, director of the forest test, and you Hanming, the leader of the forest cultivation group, followed in the footsteps of Chen Mingquan, a breeder, on a steep slope with a bare surface. In this bare and collapsed land, 15 Acacia trees with a height of 6.5 meters under the branches and straight trunks were found by the Forest Bureau Rangers, which were designated as mother trees, and then seed and ear harvesting were commissioned by the Forest Test Institute.

During the Japanese occupation, Japanese acacia trees were unique and easy to use, while the Acacia trees originally distributed in Hengchun Peninsula were planted all over the island and used as firewood and charcoal in the daily life of ordinary people. But how capable is Acacia Mu? The collapse-prone land of Danda may be the answer. We marched through this steep, exposed woodland, and the soft soil slid from time to time, climbing with our hands and feet, so as not to slip with the earth and rock. However, in such an environment, Acacia can hold on to the land and inhabit it without being shaken.

All 15 mother trees have long been numbered, and everyone followed Chen Mingquan's steps, looking for traces, and every time they found one, they could not help admiring the tall, straight tree. The mother tree No. 7 is an example. The visual height of the tree is more than 20 meters. It is not only 7 meters high under the branches, but also has a diameter of much more than 30 centimeters at breast height. The tree is strong and meets the requirements of "straight and perfect" in the forestry population. There is a fallen acacia tree beside it, the profile shows that it is all solid, and the color and grain are satisfactory, which is exactly the characteristic that the researchers are looking forward to.

"Acacia trees are the first low-altitude afforestation species. Although they seem to be everywhere, we need to look for straight trees as mother trees. Only by raising seedlings for afforestation can we be competitive in timber production and utilization in the future." Zhang Bin said.

Subvert the Acacia tree "twist" the image of the tall mother tree is invisible in the vast mountain forest.

Since 2015, with the support of the plan of the Forestry Bureau, the Forest Test Institute has launched a draft of Acacia mother trees to select Acacia trees that are straight and perfect in shape, with a breast height of more than 35 centimeters and a height of more than 15 meters. Acacia trees with no diseases, insect pests, distortions or decay on their trunk appearance will be designated as mother trees, and then seeds will be collected from them and seedlings will be raised, hoping to open a day of Acacia wood.

The attentive rangers of the forest management offices of the Forestry Bureau look for the mother trees that meet the standards during the mountain patrol, assemble the visual data and coordinates to the afforestation production team of the Forestry Bureau, and then provide the acacia research team of the Forestry Experimental Institute. On-site to identify, calibrate and record the basic data of excellent mother trees, including longitude and latitude, slope, altitude, orientation, stand status, and so on.
