Located between patio slabs at a house in Southern California. Am looking to possibly replace it during the cosmetic repairs planned for the area. Even if I don't replace it, am wondering what this stuff is called and what it's supposed to do.

Looks like landscape edging, maybe used as a form. You could just pull it out and not replace it, but you might fill it with sand or dirt to keep other things from piling in or prevent mosquito water.
