The chromosol soils of the Duri district range from highly to moderately degraded. The poorer condition results in high overland flow, reduced plant available water, and can lead to greater recharging of lower lying vertosol soils, which have a greater salt store and as a consequence of recharge...

Nature reserve planning models to maximize species protection are typically formulated for a single period using certain data. In practice, however, parcels must be acquired over time. The status of a parcel may change due to conversion to alternate land use. Populations of species to be...
