Annual Report 2018 Council of Agriculture, Executive Yuan In order to limit the damage from Typhoon Soudelor, the COA used ladder-type groundsill works to strengthen the existing submerged dam foundations of the #2 and #3 dams on the Xiongkong River, in order to reduce the height of the high dams, and also keep the transverse eco-corridor unimpeded. F. Mountain management and disaster prevention in watersheds in national forest Taking the watershed as the unit of management, and based on the results of risk surveys and evaluations of landslides and watersheds in national forest, and aiming at the same time to deal with disasters caused by typhoons, in 2018 the COA appropriated NT$505 million to complete 112 construction projects (i) to handle landslides in upstream sections of national forest; (ii) to build sedimentation- prevention infrastructure; and (iii) to conduct maintenance and emergency response measures. We handled a total of 91.56 hectares of landslides, did maintenance work on forest roads and slope management over 117.63 kilometers, and stabilized about 3,127,400 cubic meters of soil from shifting downward. These steps will allow restoration of forest Stacked stone construction was adopted to stabilize the slope of the Beizaitong Forest Road, and the wall was integrated into the surrounding natural scenery to make a beautiful natural environment. land as quickly as possible and ensure safety in national forest. In addition, starting in 2018, all management construction projects under the Forestry Bureau have included an ecological impact mechanism, with the ecology taken into account throughout the life cycle of the project. G. Monitoring and management of slopeland Categorizing and defining slopeland by the limitations on its permissible use, and setting norms for agricultural activities on slopeland, in 2018 the COA completed inspection and definition of 10,144 hectares. We have also demarcated “designated soil and water conservation areas,” for which we devise long-term soil and water conservation plans. In 2018 the COA conducted an across-the-board review of the plan for one such area, and eliminated two other areas. 43
