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