For standing to sue? Yes

Why would a special interest group be able to sue to protect frogs, but another wouldn't be able to sue to protect unborn babies?

They're going to have some issues bringing frogs in as a party to a lawsuit (those little green bastards can't even sign the appropriate paperwork... lack of opposable thumbs) but there's nothing legally noteworthy about a non-profit group obtaining standing to sue the government about an environmental or ecological issue that is covered under statute, or under the executive branch/EPA's enforcement jurisdiction.

>that is covered under statute,

And this Texas law gives statutory standing.
