More or less yes.

Eucalyptus can survive forest fires and at the same time supports the spread, which can also trigger fires several kilometers away.

And all this to destroy all the other plants in the area.

Hello,

Yes, of course! Out in the forest, merciless struggles run, but so slowly that we do not perceive it.

Now in the spring you can see germs of trees at many places, the maple and beech seeds have already evolved. Sometimes hundreds of them stand on a single square meter. Each one of them tries to grow faster than the others, to spread over the others, to get even more light and to grow even faster. Sometimes everything is over again after a summer: at many places the old trees only leave so little light that the little ones can not grow further when the reserve materials are used up in the seeds, they would have to do enough photosynthesis themselves, but that is not enough. If they can continue to grow: at a height of one meter, from the originally several hundred on the square meter, perhaps there is room for not more than ten pieces of them. And from really large trees, each individual claims a space of about 100 square meters for himself. All the others who had risen once on the ninety-nine square meters around, he then successfully displaced.

And there are even tree species such as walnuts that are able to prevent others from germinating in their surroundings:

Yeah, they can. They can communicate and kill each other. Weaker trees are removed. By removing water and nutrients. But not only trees,but also certain shrubs like the slums can make many square meters in the surrounding other shrubs and also smaller trees difficult to grow and spread.

Yes, they can. Zb slowly kills the worms their host tree by slowly strangling him, as the name suggests, to death, light, water and nutrients. Their seeds germinate zb in stilts and form air roots that grow to the ground. As soon as they reach the ground, the little fig grows quite fast and kills her host tree. It remains in its interior a cavity where before the stem of the host tree was

There is also a fight for light and nutrients in trees.

If one grows faster than the other and gets too little light.
