This is an invasive weed, a plague.
Pinus elliotis was extensively used here to make cellulose paste to obtain paper.
What a disaster! It went wild!
Look here it is growing literally on the rock.
It used a termite next to germinate and  notice what else is there but not for too long...
All the other pine trees here seen are invaders. They were not man planted.
Pinus elliottis is a North American  resident and here it is a nonsense.

This is close to Arroio dos Ratos in Rio Grande do sul.
Dyckia hebdingii
