Some evidence is showing the abundance of grasses and sedges is super important for native bee conservation!
Why? They have fine roots and they begin to build up the organic matter back to pre-settlement levels. This organic matter is necessary for the ground to absorb and hold water. What does that have to do with native bees? The water regulates the soil temperature. Many native bees are ground nesting and they need that heavy organic matter to nest in and a well regulated soil temperature to thrive. We lost this organic matter through oxidation over centuries of tilling agricultural practices. Plant the grasses too! It takes a long time, so let's get going!
