Jakarta – Twenty percent of District III of Kerinci Seblat National Park in Bengkulu and South Sumatra has been destroyed by farming and the local administration's construction projects, an official says.

"The destruction of Kerinci Seblat National Park District III is predicted to reach 20 percent of the total 600,000-hectare area," district management division head Donal Hutasoit said on Tuesday in Rejanglebong, Bengkulu, as quoted by Antara news agency.

He cited construction of a road in Bengkulu's Bermani Ulu Raya district, which was currently under police investigation, as one of the causes of the destruction.

Donal added that the destroyed parts of the conservation area mostly bordered with forests available for exploitation.
