Nice article and very true! To help native pollinators you can plant native flowers, and also very important: leave the dead plants in your garden at the end of the season. The pollinators use the stems of dead plants for their overwintering. Please don't place a ton of insect hotels either, solitary bees aren't supposed to nest together and you will get mites and other pathogens that infest the baby bees (this happened in my garden and all my neighbors gardens...). If you do want an insect hotel for mason bees, clean it out every year and replace the tubes where the bees lay their eggs. Also store the tubes in an appropriate place in the winter, but be sure to put the tubes with eggs outside when it's time to hatch :)
