(I tried the link, but it didn’t work.) In any case, the way this is worded, it sounds like the plant purposefully makes itself bitter. I’d like to know what mechanism causes the plant to become bitter when the hare population is high. Also, it seems to me that the hares (at a normal population level) might give the plants some benefit; otherwise, why wouldn’t all the plants be bitter all the time? As one of these individual plants, wouldn’t your chance of survival be much greater if you were always bitter- unless being bitter caused some hardship (i.e. using too many precious resources)? Are some of the plants bitter all of the time, and only the bitter ones survive because they’re not eaten?

Nature also produces beings which have the ability to echolocate. So, I wouldn’t be quick to dismiss something that produces echolocating beings as non-echolocating.
I think sentience is overrated by humans. Sentience happens to be our one trick in our bag that allows us to reproduce and prosper. For us, it’s our ticket to survival. Sentience wouldn’t give bats an advantage; they’re pretty well suited to what they do, and larger brain size would hurt rather than help them.
We tend to view “Nature” (with a capital N) as sentient, because we are sentient. From the bat point of view (if they had a point of view) echolocation would be the epitomy of evolutionary progress.
It’s just difficult for us to comprehend non-sentience, especially when non-sentient organisms show what seems to us to be a good plan. Too many hares? The plants become bitter. Too many people? Disease will decimate the population. These things happen, but sentience isn’t necessary for them to happen.
