Introduction

Goats were brought to Australia on the First Fleet as a source of meat and milk. They were taken wherever early settlers went, and many were released into the wild. Feral Goats are currently not a problem in mainland Northern Territory, with their spread being kept in check by Dingos. However, they are found on a few offshore islands, including North Goulburn Island, Truant Island, off Nhulunbuy, and Vanderlin and West Islands in the Sir Edward Pellew group.

Introduction
A wetland is any non-marine environment that is, to some extent, water-dominated. Wetlands can be comprised of standing water, such as in a lake; of flowing water, as in a stream or estuary; or merely of water that saturates the soil for significant periods. They may be fresh or saline, and fed by tidal waters, stream flow or groundwater.
Wetlands may be permanent, or last only a few weeks each year, or a few months every decade or so. Wetlands include the riparian zone and floodplains along creeks and rivers and the vegetation growing in them.
