... play a critical role in nearly every ecosystem. They are key in recycling dead vegetation and making the nutrients available for the next generation of plant life. They provide a source of evolutionary pressure as plant pathogens, and help keep rampant monoculture plant populations in check.
I probably already knew that, but it served as a reminder that in a healthy ecosystem past and present are intrinsically linked, a concept perhaps best symbolized by the nursing logs:
