Create random mangrove trees

Hi,

I am currently working on the implementation of 30 apartments on a riverside. I wish that these dwellings mimic a mangrove. The height between the riverside and the water is 8 meters, and the dwellings would come 1 meter above the water.

The shape would follow a fractal model, which means that the n+1 branch starting from the side of the n branch would be thinner. The first branch would start from the riverside, and progressively all the branches would cling to the river bottom.

Kindly,
