What temporal and spatial data may be included? | Pest distribution and intensity of infestation |
Which management units may be included? | Measures of potential or actual impact on biological values, agricultural values, environmental values, recreational and social values and public health values. |
From where may data be obtained? | Direct observation, historical records, GIS, satellite information and air-flown MSS. |
