The Social Life of Forests - The New York Times (nytimes.com)
If you listen to podcasts the NYT article “The Social Life of Forests” is also a NYT podcast titled " The Sunday Read: ‘The Social Life of Forests’" in the NYT “The Daily” podcast. I found it very interesting and adding to my understanding of horticulture.
