Why is black plastic tubing coming out of the ground next to trees in my street?

A number of trees in my street have black tubing coming 10-20 cm out of the ground next to them.

What are these for? They are very wide and get filled up with junk.

I've wondered about these too. I'm not sure what they're for but have seen similar pipes around many new tree plantings. I guess I've always assumed they're a way of delivering fertilizer/ventilation/water to a tree's deep roots as it establishes itself after transplanting.

I think what you're seeing is probably part of a aeration system somtimes built around trees to protect them during some types of construction.
