Early last century, the island's vegetation was composed, almost entirely, by gorse and scrub as can be seen today in the Estelas islands, two small islands at the entrance to the bay of Baiona. The island was originally a small rocky island with a small beach facing south-east and almost no vegetation can be seen in a relatively recent photograph taken in 1970, the bridge that links the mainland and built and planted with trees in the second decade of last century by D. Martin Echegaray.
The first trees were planted by D. Martin Echegaray Olañeta after buying the island to Enrique Lameiro Sarachaga in 1910. From this plantation are still preserved some specimens, almost ancient.
Due to lack of care and maintenance, practically in a state of neglect, was subjected to the island for over 35 years, from 1939-1975 and as a result of the storms of winter, a large part of that tree lost.
It was from the urbanization of the island in 1975 when owners decided Communities allocate part in their annual budgets for the recovery of green areas and restocking them with new trees.
Currently the island has magnificent examples of pine trees (wild and pinion), eucalyptus, cupresos, Araucaria, Metrosideros, Lagunari, bay, chestnut, cherry, poplar, elm, olive trees, cedars, firs and also, bush varieties as tamarind, melaleuca, ebonibus, privet, myrtle, pittosporum and etc..
In the months of autumn are born in very small amounts variety of edible mushrooms, such as trichome equestrian, the boletus edulis or revellón, the chanterelle or Lactarius deliciosus and sangifluus, several kinds of mushrooms, etc. There is also poisonous mushrooms such as amanita, muscaria in their varieties and phalloides.
