The paper sets the scene with historical and professional organizational perspectives briefly describing the activities and publications of groups concerned with statistical ecology and environmental statistics. Then follow the scientific perspectives with examples illustrating certain basic issues and features arising in ecological and environmental work. The observational studies, visibility bias, and inferential recovery constitute a critical problem area. It is discussed at some length with examples and data sets. Extrapolation issues constitute another critical problem area. Different kinds of extrapolation are briefly discussed with examples of low-dose extrapolation and calculated virtually safe dose levels. An example of recruitment distributions and inferences about long-term yields is also given. The issue of single versus several models is touched upon. The present day status of the subject of quantitative risk analysis is briefly described. A need for a focal cooperative program in statistical ecology and environmental statistics is identified.
