It is considered good industry practice to remove from an exploration area every-
thing that has been brought in

Consumed, eventually leading to sanitary waste
consequent slipping and slumping. Therefore, where practical, clearing of vegetation should
be kept to a minimum. Removing of rootstock or vegetation on ridges or steep slopes, or
where soil development is minimal, should be avoided. Where areas are to be cleared of large
timber, timber not used for construction should be stored for use at other sites where timber
availability may be limited. 'Trash' vegetation (leaf litter, bark, twigs, timber off-cuts, or saw-
dust) can be used as a surface cover to reduce potential erosion. Vegetation declared as a 'pro-
ductive plant' but which is to be disturbed or removed during exploration, needs to be tagged
and numbered. Records should be kept identifying species type and diameter at breast height
(DBH), and tree height. Good pre-planning will require all tagged trees to be registered on
a database, with compensation to landowners to be calculated on a regular basis, as admin-
istered by the Government. Appropriate measure should be taken to minimize disturbance
of rare or endangered l ora and fauna. Fauna breeding or nesting areas should be avoided.
Exploration drill rigs and other vehicles/machines should be thoroughly washed when mov-
ing between separate exploration areas to reduce the spread of vegetation diseases and weeds.
FIRE PREVENTION
Fire prevention is always of concern when working in remote areas. Fire extinguishers
are standard items on all contractor machinery and drilling equipment. Field crew mem-
bers who smoke must ensure that cigarettes and matches are extinguished after use. Local
i re regulations should be observed. All i eld crews should be familiar with i re prevention
procedures, particularly around drill sites and in i eld camps.
