Yes definitely there are three sloths there and lots of birdlife too.
It suprised me when I was told about the sloths because I just would have never have imagined it either.
That said it was historically very biodiverse and believe it or not there were black lion tamarins recorded in parks and green areas of Avenida Paulista a little more than a century ago.
When you say marginalized do you mean because it is a bit of a rough area after dark ?
Gosh, many of the brazilian megalopolis are inserted in really biodiverse areas. It's great to imagine tamarins living in São Paulo.
About the marginalization, I'm mostly talking about the high index of prostitution in those areas. Not being prejudice about it, but areas where this kind of "business" predominates, are left abandoned by general public and many times by the government... Saying this from cases I've heard in places around BH metropolitan area, but I don't know anything about how Trianon park is nowadays. I didn't have the chance to visit the place in any of the times I was in SP city.
