The most intersting part to me is thinking about why those seedlings (other than the weeds) never appeared when there was grass present. Were they there and I missed them? Did they get mowed down to the point that they didn't survive? Or did the seeds filter down through the grass and wait until the more competitive grass was no longer there so they could germinate? 

 Hmmmm.....
Perhaps the grasses secrete allelopathic compounds that inhibit germination. California sages do this. I've often wondered if Witchgrass (Panicum capillare) also does this.
