Botanical gardens have long contributed to plant science and have played a leading role in
ex situ conservation, namely of threatened tree species. Focusing on the three botanical gardens of
Lisbon (i.e., Botanical Garden of Ajuda—JBA, Lisbon Botanical Garden—JBL, and Tropical Botanical
Garden—JBT), this study aims to reveal their natural heritage and to understand the historical
motivations for their creation. Our results showed that these gardens contain a total of 2551 tree
specimens, corresponding to 462 taxa, within 80 plant families. Of these, 85 taxa are found in the
three gardens, and more than half of the taxa are hosted in JBL (334 taxa), whereas 230 and 201 taxa
were recorded in JBT and JBA, respectively. The motivations for the creation of each garden are
reflected in the different geographic origins of the trees they host in their living collections. The
Palearctic species are dominant in JBA and JBL, and Tropical trees prevail in JBT. With more than
250 years of history, these gardens hold an invaluable natural and historical heritage, with their
living collections providing valuable sources of information for the conservation of threatened plant
species, at local and global scales
