There have been a ton of wonderful books published recently on native plants and pollinators.
Here are some from which I've learned quite a bit.
From the Xerces Society, many publications on bugs! https://xerces.org/publications A few of my favorites are their books Attracting Native Pollinators and Gardening for Butterflies.
I also really like this book, Climate Change Gardening for the South by Barbara Sullivan.
There is a whole series of native plant "primers" published by Timber Press. Doug Tallamy's books have also been published by Timber. His first book Bringing Nature Home got a lot of attention, with good reason, providing a push that really helped the "plant native plants!" movement get going.
Pollinators of Native Plants by Heather Holm is also a fun book, published by Pollinator Press. (A whole publishing company for pollinators?! Maybe we have a chance to save the world after all!)
Tracks and Sign of Insects and other Invertebrates is a really fun book to flip through.
