Often. They are, after all, going to drop seeds in one form or another. And the conditions are good there for that tree, so others will live there also.

And the tree serves as a focal point for so many other things. Squirrels and birds will bring food, (seeds) to the vicinity.

Wind tends to swirl around a tree, dropping airborne seeds in the area.

Some trees can promulgate through runners, creating off spring near by.

That's all the botany you'll need, But you've got to consider the human factor. Thousands of years ago forests were everywhere, and trees weren't in clumps - you just had a few places where trees wouldn't grow. Then the human population expanded and we cut down the trees to make way for crops, houses, roads, as firewood, etc. We left trees in places where we couldn't grow crops, or at field boundaries, by lakes, or in small areas where we wanted to grow wood as a crop.

So now the main reason for seeing clumps of trees is the fact that human's have left a clump of tress standing for one or more reasons.

becuase all the seed fall from the tree and may only be heavy enough to drift a small distance away, then you get more trees, and more, and then you end up with a clump of trees!!!

several reasons actually

- seed disperal of trees isn't a very efficient system without the use of animals to carry the seeds away, after eating the fruit and depositing the seeds in fecal matter. even then, the animals that eat the seed wswith the fruit, tend to stay close to their food source.

- some trees reproduce by cloning themselves by branching off a parent's root system.

-some seeds are dispersed by water and multiple seeds are carried to their final destination as runoff carries them down a hill or slope

-wind dispersal works similar to water in that the seeds dispersed by wind are blon in the same direction, and seeds that have approximately the same mass will be carried the same direction and distance.

-but the main reason, is that seeds usually fall from trees in fruit as they ripen and drop to the ground.

Sometimes they are planted that way or birds or squirrels have dropped seeds, other times the seeds have taken root around the tree where they fell.

cuz the seeds don't fall 2 far from the tree

because these trees come from the seeds of a nearby tree.

ha ha! your all wrong! its water source, otherwise the tree's would have evolved other ways to dispense their seed, where one tree can grow another can,

it would seem the logical result of seeds,nuts, fruit from the original tree falling and germinating there where they fell.

Because thats the way they were planted, so that the gardner didn't have to far to crawl.
