Passignano on the northern shoreline Isola Minore is largely covered by
holm oak woodland and
stone pine stands and is known for supporting a substantial colony of
cormorants. Research published in 2024 estimates that Isola Minore hosts a wintering population of approximately 6,000
great cormorants, which migrate seasonally from the
Baltic Sea and the
North Sea. The same source notes that this migratory pattern appears to have altered in recent years, possibly in response to rising average temperatures. According to early 20th-century accounts, the island's terrain consisted of wooded areas and cultivated olive groves, which were noted at the time for producing high-quality olive oil. == Religion ==
