(in terms of HB research): Acid rain has caused the leaching of calcium, a natural component of HBEF soils very important to plant growth, from forest soils over the past several decades. In 1999 an experiment started in which calcium was added to an entire watershed in an effort to restore soil calcium pools to pre-acid rain levels and study the corresponding ecosystem response.
