LONDON -- Mourners who scatter the ashes of their loved ones on the mountaintops of Scotland are being warned that they are playing havoc with the environment. The problem, it seems, is that cremated human remains make a dandy fertilizer.

Critics say the practice is upsetting the foliage by causing plants to grow too fast and too thick.

"The instant you put [human ashes] down on the ground," says one professor, "you are getting luxuriant growth" of vegetation.

The Mountaineering Council of Scotland says nature lovers and other admirers of Scotland's picturesque mountains have taken to requesting in their wills that they want their ashes dumped on the summit of their favorite peak when they die.

The result, the council says, is that a number of the more popular mountaintops are all too frequently being dusted by cremated remains, and the practice is having an unwanted chemical effect on the ecology of the surrounding area.

What happens is that plant growth is being stimulated by phosphate enrichment and changes in the acidity and alkalinity of the soil, marring the bleakness that many find so attractive in Scotland's mountain ranges.

The key is in the types of soil found on the mountaintops, Des Thompson, principal uplands adviser to the environmental group Scottish Natural Heritage, told the British Broadcasting Corp.

"They are acidic, they are impoverished," he said. "They have very small amounts of minerals such as calcium. They are very wet.

"And in an environment such as that," the professor said, "the ash is providing a bean feast for the plants. The key nutrients are nitrogen and phosphorus and potassium, [and] ash is full of phosphorus and calcium and other nutrients.

"The instant you put that down on the ground," he said, "you are getting luxuriant growth of vegetation."
