Efforts of ex-situ conservation need to be carried out to prevent threat of extinction in plant species of Annonaceae family, and one of them is collected at Purwodadi Botanic Garden (PBG). The collections of Annonaceae in PBG have experienced dynamics over the past of 12 years. These dynamics affect diversity and conservation efforts. This study aims to determine the dynamics or development of Annonaceae plant collections in PBG for the past of 12 years and how their conservation efforts. The methods used primary and secondary data collections, measurement of stem diameter, plant height and branch-free stem height (BFS) to determine the condition of Annonaceae plant collections related to their adaptation in PBG and measurement of microclimatic data. Data were analyzed descriptively and analyzed by Principal Component Analysis (PCA) using the statistical program PAST 4.0. The Annonaceae plant collections in PBG have fluctuated in the number, genera, species, specimens and genera that have not been identified. Dominant originated from East Kalimantan, East Java and South Kalimantan with plant addition of 28 numbers, 10 genera, 6 species, 58 specimens, 7 genera that have not been identified to the species level and 81 times of species identity changes. Annonaceae plant collections in PBG was able to well adapt and develop based on the average of stem diameter, where collections was planted in 1980s have larger stem diameter than the 1990s and 2000s. Humidity and light intensity are the most influential environmental factors for plant growth, especially for branch development (stem diameter and BFS). The management of Annonaceae plant collections in PBG was the maintenance activities such as pruning, watering, fertilizing, pulping, data collecting, monitoring of flowering and fruiting for selected collection plants and adding of plant collections through exploration activities) and several studies to explore aspects of species usefulness to support of conservation.
