Located in a shaded valley west of Alto de Coloane, the Coloane Arboretum is an ecological park that primarily caters for conducting scientific research and implementing science popularisation programmes, complemented with sightseeing tourism development. Started constructing in 1986, the Arboretum covers an area of 6,500 square metres planted with 39 families and 88 species. It is Macao’s only gene bank for tree species, in which the species from the islands’ reforestation are maintained and new species are also introduced. It is a theme park for understanding and appreciating trees.
