Forest protection invites trouble for trees

Keeping the loggers out of forests doesn't seem to displace deforestation, but the people protection attracts can be damaging in other ways

DOES protecting forests simply displace deforestation elsewhere? One study published this week suggests not, while another warns that it attracts people seeking work, threatening forest and wildlife.

Both studies focus on 鈥渘eighbourhood leakage鈥 鈥 the idea that banning logging in some areas pushes it elsewhere.

at the University of Kent in Canterbury, UK, found that between 1990 and 2000, deforestation in Sumatra was lower both in protected areas and within 10 kilometres of these zones than in more distant unprotected forests, suggesting that neighbourhood leakage was not occurring (Journal of Biogeography, ).

A second study of 306 protected areas in 45 countries by George Wittemyer of the University of California, Berkeley, found that rural settlements near protected zones grew at twice the rate of those elsewhere (Science, ).
