Why+They+Are+Endangered



=When the early Europeans came thousands of years ago, they brought in rats, cats and other pests that ate every single Black Robin living, except the ones on Mangere Island. About 20-30 Black Robins managed to survive for the past 90 years on a few shrubs, on top of a 200m high mountain on Mangere Island, because the grasslands were drying out due to a shortage of rain. = =Since the Black Robins all share the same DNA, a single disease could kill all of the Black Robins in the world. = =The forests and trees area on Mangere Island were cleared for a helicopter landing site years ago, and we humans are still doing those same foolish and useless things. = =But we are not the only ones causing harm to these wonderful creatures, the sea salt winds on Mangere Island, are damaging the forests and trees, which is home to the Black Robins. = =﻿=
