Round
Island is the remnant of an extinct, eroded and now partly submerged volcanic
cone situated about 15 miles north of the large island of Mauritius in
the southwest Indian Ocean, east of Madagascar. Mauritius itself, formerly
the home of the now extinct Dodo bird, has been devastated by human induced
environmental disasters of many kinds. Its flora and fauna now rank amongst
the world’s most threatened. Round Island is sufficiently isolated that
not only is it the final refuge for many Mascarine endemics, but over the
eons, a number of unique animals and plants have evolved there, but like
Mauritius, it has suffered degradation. In the early 19th century goats
and rabbits were introduced to Round Island. Their browsing was largely
responsible for the total loss of the island’s natural hardwood scrub-forest,
the severe degradation of the last example of a unique palm association,
as well as the loss through erosion of around 90% of the island’s soil.
So severe was the destruction that this photo shows the only remaining
individual of the Round Island Hurricane Palm on the island. Goats were
removed in 1979 and in 1986 Don Merton and team eradicated the rabbits,
thus saving this unique plant species along with ~15 other Red Data
Book plants & animals in their native home.
