While the science of restoration has generated many successes, some habitats are very difficult to restore, making certain decisions effectively irreversible. For example, Acacia nilotica was introduced into Indonesia in the 1850s for gum arabic, with planting expanded for fire breaks in the 1960s. This tree became invasive and has already replaced >50% of the savanna habitat in the Baluran National Park, with complete replacement expected in the near future. This shift from savanna to acacia forest is causing large declines in native species, including the charismatic wild banteng, Bos javanicus, and the wild dog  . Multiple approaches to controlling the spread of this acacia have been ineffective, highlighting the difficulty of reversing the decision to plant this tree . Another example is the difficulties in restoring the tropical peat forests of SEA .
