Huarango Woodland Restoration Project

Posted on 14 September 2016

The ancient Nasca people drove themselves to near-extinction by replacing woodlands of the huarango tree (Prosopis pallida) with intensive farming practices.  Without huarango trees to release moisture to the atmosphere, the local climate became progressively drought-prone, thus dooming the agriculture in this very arid part of southern Peru.

Royal Botanic Gardens, Kew is working with local people, government and industry to re-establish hyperarid woodlands in southern Peru. For more than five years, school children and their parents have learned about the importance of the native huarango tree to their own economic well-being, and have become major partners in re-establishing the woodlands and conserving remnant stands of native vegetation.

They have propagated tens of thousands of native trees, shrubs and herbs and the new woodland is over one kilometre long.
