Well I've read different articles over the years, or saw videos that showed how plants have kind of 'nervous system', where radiative particles were put into a plant, and causing distress to a leave on side, sends information across it's 'system' that lets the entire plant 'know' what and where distress is happening.
I've read an article where tree groves are interconnected, especially via it's root system, where touching root systems underground create a connection and 'awareness' of other plants/trees in it's system. Trees that are ailing due to some disease will be sustained by trees around it. Sometimes a tree is cut down, but the remaining stump has an intact root system, and even without foilage can be kept alive for decades by the trees around it - keeping the stump alive.
Now this suggests trees in distress emit sounds...
Apparently the botanical systems of trees are so complex, in some ways possess features that are handled with different systems for animals, but have similar utilization in ways we are only beginning to understand. Perhaps, just as animals, once we figure out how to do it, there are probably more effective means of communication and interactions with plantlife...
