Abstract
ABSTRACT Large old native trees are outstanding physical and ecological features in habitat remnants and landscapes in urban areas. Being able to estimate the age of these trees is important to our understanding of the potential impacts of environmental changes and their persistence in urban ecosystems. Here, we report on the ages of several native trees in forest fragments and within the urban landscapes in Singapore, estimated using radiocarbon dating. A Rubroshorea macroptera tree removed due to poor health and safety risk was estimated to be 215–511 years old. A Rubroshorea curtisii tree that had naturally fallen was estimated to be 211–372 years old. Climax forest tree species of Southeast Asia consistently appear to have lifespans of a few hundred years, even in forest fragments and urban landscapes in a city.
