Ecological Role and The Re-wilding of Rodrigues
It has subsequently been discovered that the browsing herds of tortoises filled an essential role in the island's ecosystem and the regeneration of its forests. Among other roles, the tortoises ensured the dispersal and germination of the trees' seeds, as well as "terraforming" by maintaining forest-clearings and pools.
In recognition of this fact, measures have been undertaken to introduce replacements, in the form of similar species of tortoise from other parts of the world, to assist in the rebuilding of Rodrigues's devastated environment. The replacement species for the Saddle-backed Rodrigues tortoise was chosen to be the Aldabra giant tortoise (Aldabrachelys gigantia) of the Seychelles, which is roughly similar in size, though very different in body-form.

Famous quotes containing the words ecological and/or role:
“It seems to me that there must be an ecological limit to the number of paper pushers the earth can sustain, and that human civilization will collapse when the number of, say, tax lawyers exceeds the worlds total population of farmers, weavers, fisherpersons, and pediatric nurses.”
—Barbara Ehrenreich (b. 1941)
“A few [women] warrant our attention not because they have the answer but because they have rejected the mentality that insists there must be one answer. What makes them role models is not how much or how little they work, how many or how few hats they wear, but rather how well they understand, and accept, that for all rewards there will be commensurate sacrifice; for all gains, some loss; for any pleasure, some pain.”
—Melinda M. Marshall (20th century)
