  • The Galápagos are famous for their reptiles and birds

  • but much of the islands' flora is equally interesting

  • and it's just as vulnerable to the impact of humans.

  • Over the last centuries, almost 500 species of plant

  • have been imported into the Galápagos,

  • some for agriculture, some for gardens

  • and some by accident.

  • Like the wild goats who compete with indigenous tortoises for food,

  • so these newcomers compete with local plants

  • for sunlight, soil and water.

  • Santa Cruz, for example, is home to a unique species of plant

  • called miconia, which is only found on one other island.

  • Today, it is under threat from the red quinine tree.

  • First brought onto the island in the late 1940s,

  • the red quinine tree is very hardy

  • and it reproduces so rapidly that there were worries

  • that it might wipe out the whole of the miconia zone.

  • Today, the National Park Service are actively engaged in a programme

  • to eradicate red quinine...

  • ...injecting any seed-bearing trees

  • with cartridges filled with herbicide.

  • It's expensive, time-consuming work and there are many trees to kill

  • but scientists are optimistic that they may eventually eradicate

  • the most damaging newcomers.
