Beeb Reports on Butterfly Highway

A BBC report on closing a Taiwan highway to protect migrating butterflies is getting play on blogs all over the world:

The purple milkweed butterfly, which winters in the south of the island, passes over some 600m of motorway to reach its breeding ground in the north.

Many of the 11,500 butterflies that attempt the journey each hour do not reach safety, experts say.

Protective nets and ultra-violet lights will also be used to aid the insects.

Taiwanese officials conceded that the decision to close one lane of the road would cause some traffic congestion, but said it was a price worth paying.

"Human beings need to coexist with the other species, even if they are tiny butterflies," Lee Thay-ming, of the National Freeway Bureau, told the AFP news agency.

Each year thousands of butterflies die when turbulence generated by fast-moving cars drags them into the traffic or under the wheels of oncoming vehicles.

Ecologists hope the triple-action effort of lane closure, protective nets and ultra-violet lighting will dramatically increase the milkweed's chances of reaching the breeding ground.

Good work, Taiwan.
