See AnswerQ: Could protecting forests that once burned with regular frequency, due to
Could protecting forests that once burned with regular frequency, due to lightning strikes, lead to reduced plant diversity within a mountain forest landscape of 25 km2 (~10 mi2)?
See AnswerQ: If disturbance can foster higher species diversity, why is human disturbance
If disturbance can foster higher species diversity, why is human disturbance often (though not always) associated with reduced species diversity?
