We witnessed, first hand, how important "weeds" are to the ecosystem. The city stopped treating the grass in the park behind our building with herbicide this year. In the spring we had one of the largest dandelion blooms I've seen since my childhood. As we've been feeding the squirrels this summer we've noticed the honeybees are coming back in numbers I haven't seen since we've moved to this part of town (2018). I guess the hives rely on that early pollen from the dandelions to strengthen their population after the long winter and when we treat our lawns it starves them of that early food supply. It's amazing how resilient nature is if we just give it a chance. We've gone from seeing 1 or 2 bees all summer to seeing an entire field of them buzzing around.
