Winter

Its winter and rice harvesting season is over at the Red River Delta. Amongst a backdrop of limestone hills, cattle grazed. Vietnam is highly agricultural and I was rather dismayed to see many of the karst limestone, especially at lower elevation, contaminated by exotic flora, prickly pear cactus, Hyalocereus (bearer of Dragon fruits), Euphorbia heterophylla, Rheo discolor, Aloes and whats not - the indigenous plants are not so easily sighted, although they are no doubt present.
