Step across Xitun Road and you reach the museum's botanical garden. It sits on land that was once reserved as Park Number Fifty-Four. In 1999 the Taichung City Government asked the museum to plan and build it, drawing on the museum's expertise and educational approach. The garden opened on July 23 of that year. It covers about four and a half hectares and focuses on the lowland ecology and tropical rainforest of Taiwan. Eight zones show representative landscapes: an uplifted coral reef area, an Orchid Island area, a coastal forest, a Taitung cycad area, northern, central and southern lowland areas, and a monsoon rainforest. Counting the greenhouses, the garden holds more than 800 kinds of plants, including native trees, shrubs, herbs and ferns. The museum's work also reaches beyond the city. The 921 Earthquake Museum of Taiwan in Wufeng, the Fenghuang Valley Bird and Ecology Park in Nantou County, and the Chelungpu Fault Preservation Park in Zhushan Township are all run as the museum's branch centers. The Wufeng site was set up after the great earthquake of September 21, 1999, on the grounds of a school the quake had damaged. The bird park covers 30 hectares.
