Thank you for the interesting article regarding the whistling Frogs. As a research scientist, I have found that many people do not realize how nature thrives and functions based on sound (frequencies). The health of a forest is directly related to the number and variety of frequencies produced in a 24 hour period. Insects, animals, water ways and humans all play a part in the over all health of a forest. A forest will become ill and can eventually die if sound producing species begin to reduce in numbers or end up missing in general. Indigenous Flora needs the sound of insects, animals, water ways etc to grow and ward of disease. If the natural habitat is disturbed too much and the orchestrated sounds are reduced, the Flora will show signs of distress with disease to follow. Studies have shown that daily interaction with humans and their plants can result in healthier Flora. Believe it or not, trees love it when children climb trees, build tree houses and laugh and play next to them. The energy exchange between playful/positive humans and healthy Flora are just now beginning to be understood by science. Yes, indeed, kind words, whistling or singing in the presence of Flora can go a long way.
