It has been in Italy for the last sixty years returned to nature about 200 endangered plants or that he was already with one foot in the grave. The first, in 1958, was Bosnian pine, which later became the symbol of Pollino in Calabria. Then it was his turnfir from Madonie in Sicily, the rarest Christmas tree in the world. Migrations have proven successful and these species, with time, recover. But in many other cases it did not end so well and for many plants there is only a one-way ticket to the herb. It depends on what? The factors are different and were discussed at the first international conference on the subject organized in the capital by the universities of Roma Tre and Pavia.
The oldest extinct apple in Italy comes back to life
by Fabio Marzano
His practice all over the world folding Restoring endangered organisms to nature has never had predictable results. For Trochetiopsis erythroxylon, a species of ebony endemic to the remote island of Agia Eleni, there was nothing to do. The re-imports did not work and the plant did not even survive ex-situ, ie in a controlled crop. It has now been declared extinct as well Cyanea Superbaa palm-like tree endemic to the island of Oahu in the Hawaiian archipelago that appears to be able to reproduce in captivity.
An important part of this first topic lecture Plant displacement was also dedicated to the Mediterranean islands which, despite its sparse surface, host 7% of the world’s plant biodiversity. Between Sicily And Sardinia In recent years, re-introduction work has been carried out in nature for almost twenty plants thanks to the European project Care Mediflora, in which the University of Catania and the Cagliari Botanical Garden participated. In the list there are plants adapted to extreme environments such asSicilian starfishwhich tolerates saline environments, orGennaris’ anklewhich survives only in the limestone soils of Monte Albo in the province of Nuoro.
Also in Sardinia for the protection of its oldest specimensalty with peach leaves (Rhamnus persicifolia), an endemic shrub of the central hinterland of the island, botanists in 2018 built a kind of artificial embankment. But a torrential flood later swept it away. Today they made a new one.
