Abstract

Abstract: From November 30 th to December 1 st, 2017 has occurred extreme weather events in the Cibodas Botanic Gardens (CBG) and its surroundings. At that short moment, it has destructed many plant collections and tended to become an ecological disaster on a microscale. It has highly suspected that this happened due to the heavy rainfall and strong wind. This study aimed to analyze the volume of rain rate and wind speed conditions at pre-, on-, and post- those periods, compared to the circumstances from 2017 to June 2018, those impacts on the lost number of trees and shrubs, and to describe the CBG operator emergency response procedures. The rain rate and wind speed were inventoried monthly, but on those two days, they were inventoried hourly. The number of plant losses assessed by census analysis and the response procedures has been adjusted based on CBG ISO 9001:2015. A regression test was conducted to examine the correlation between the number of losses, rain rate, and wind speed. Results showed a maximum rain rate of 58.8 mm hour -1 and the highest wind speed up to 83.7 km hour -1 in those periods, which caused losses of 48 trees and five shrubs. The maximum wind speed was the main factor in the plant loss occurrence, where the correlation was strongly positive. However, the operator only required less than three days to manage the impacts by reporting, documentation, and inventorying the damages, cutting the collapsed trees, and cleaning and reorganizing the environment. This study has expected to provide an overview of how's CBG capability in addressing extreme weather impacts.
