AnswerOther countries than the native plants.

other areas to the area in which they are growing, for example Acacia saligna is native to Western Australia, but it is an invasive weed on the east coast of Australian. It gets even more locallised than that. Acacia elata is endemic tothe Blue Mountains about 100km from Sydney but it is an invasive weed on the coast. And more interestingly Acacia prominens GOSFORD WATTLE is an endangered species in it natural range due to its natural range being places people like to build their homes. But in the Duffy's Forest ecological community it is an invasive weed because it spreads rapidly and competes with plants that are even more endangered than itself. this is within an 100km area. Native and Endemic are mean very different things in large countries. Your local plants are provenant.

The seeds of these plants are often transported by birds, birds eat the fruits of plants and trees they digest the fleshy bit and then excrete out the seed.

Invasive plants are called invasive because they are "invading" our yard. Plants like blackberries can choke our plants to death. English Ivy can do that too. That is why we need to get rid of them.

Alien plants aren't native to the area in which they're growing. Some of the non-natives may end up perfectly naturalizing. In other words, they find spaces in which to grow without chasing out or harming other life forms in the area. Other non-natives take over the area in which they find themselves, and keep spreading. Such aliens are called invasive. For they're invaders of their new environment, to their benefit and to the detriment of other plants and life forms.
