<![CDATA[The Invasive Aliens Species (IAS) has become an ecologically distinctive threat to the conservation area which is a biodiversity sanctuary, the Baturraden Botanical Garden (KRB). This research aims to know the IAS that can affect the biodiversity of vegetation in KRB. The KRB is divided into 10 plots, and then observes the existing IAS vegetation along with environmental factors such as temperature, humidity, soil pH and canopy cover. Introductory process information and conservation strategic recommendations are obtained through literature studies and interviews with resource persons. The data then analyzed using the Importance Value Index (INP), the Shannon-Winner Diversity Index, the individual spatial distribution pattern of a species at each growth rate is calculated based on the Morishita Index. The results showed that the IAS introduction process began in 1952 through the utilization of Protected Forest (HL) and Limited Production Forest (HPT) in KRB; The vegetation community structure in the KRB is dominated by spikes (saplings), seedlings, trees and poles. There were 13 IAS species consisting of 9 families; Seedling and saplings Calliandra houstoniana var. calothyrsus (Meissner) Barneby and Agathis dammara (Lamb). Rich. while at Agathis dammara (Lamb) tree level. Rich. and Schima wallichii Choisy. potential as a special IAS in the KRB; Controlling can be done through mitigation, periodic maintenance and eradication. In situ and ex situ conservation strategy plans in KRB are the creation of forest pharmacy conservation villages.]]>
