    My textbook says 'On Northern Isabella Island, the goat has also transformed forest into grassland, leading to soil erosion.' How did the introduction of goats to the Galapagos Islands cause forests to turn into grassland? I don't understand this part of the passage.

    I highly doubt that the goats on the island would equip themselves with chainsaws and cut down the trees building their homes

    I believe it means that because goats have been introduced to a foreign island, they've been able to breed and create a large population. When the trees are cut down, the presence of the goats prevents them from growing back, and the goats make the forest their habitat.

    lol but why does the goats presence stop trees growing? I still don't understand

    EDIT: could it be something to do with altering the food chain, which might stop trees being able to reproduce (insects that pollinate them reduced in numbers/ died out)? :dontknow:

    Goats graze and will eat anything, including shoots and saplings. This stops big trees growing. They'll also eat nuts and big seeds and things. Small plants like grasses are OK because they grow and reproduce quickly, but trees which require a good few years before they're even big enough not to be eaten won't grow back.

    Pretty much this, we have a couple of goats in our garden and they completely demolish any grass on the field, very useful and cute animals
