Indeed. If you would care to check out the early events of
The Beauty of the Garden, you will see the events that transpired.
There were many things that seemed to have unusually electronic and technological properties not expected of the life of this realm. Mechanical contrivances appeared without warning on livestock. We then found these fungi, each bearing a transmitter. I was engulfed by one such thing, and found that the insight was illuminated by a great many crystal diodes, lighting up in strange patterns. I have, to the best of my ability, recorded many of these patterns. By now, there are books and books about them in my studiolo. The synthetic contraptions added to the plants were utilized by them in an elegant manner, but were not vital to the survival of the organism.
Another matter of some use: there was a transmitter that the spawn of Earnaness brought us to. It was masked by trilobites, and it summoned the sslugs and the Citadel to us. There may well be some similar thing summoning the next heralds.
