Farming shrinks butterfly gene pool
Farming shrinks butterfly gene pool Healthy populations of butterflies can lose some
of their genetic diversity as a result of intensive agriculture. A
population of rare butterflies in North Wales was re-introduced to
the area in 1963. The population is apparently thriving, but
researchers have found that the butterflies have lost some of their
original genes. James Mallet of University College London, has
found that some of the rarer varieties have disappeared.
Butterflies have adapted to habitats shaped by farming and forestry
practices, but are now threatened by intensive farming. Mallet
believes that, where possible, we need a return to traditional
farming methods to conserve the native flora and fauna. 21 SEPTEMBER 1996, P. 15
