 The absence of any form of paving between the <unk> rows contributes to the simplicity of the cemetery designs . Lawn paths add to the garden <unk> , and are irrigated during the dry season in countries where there is insufficient rain . Where irrigation is inappropriate or impractical , dry <unk> is an ecological alternative favoured by the Commission 's <unk> , as is the case in Iraq . <unk> areas require a different approach not only for <unk> , but also to plants and styles of planting . Similarly , there are separate <unk> <unk> in tropical climates . When many <unk> are concentrated within a limited area , like along the Western Front or Gallipoli peninsula , mobile teams of <unk> operate from a local base . Elsewhere , larger <unk> have their own dedicated staff while small <unk> are usually tended by a single <unk> working part @-@ time .
