Yup, small conservations efforts can make a real difference.

Leaving sections of our yard a little more wild, and bird and insect population went up, this includes lightning bugs, which we continue to get in abundance (we're in a reasonably urban area).

I've planted milkweed, it took a few years, but now we get monarchs every year too.

Jonathan Franzen wrote a great article on this that went viral (considering the topic) a few years ago https://www.newyorker.com/magazine/2015/04/06/carbon-capture . He basically argues that the cataclysmic worries about climate change should not paralyze us to make changes that promote local conservation, which have real tangible benefits for biodiversity on a small scale.
