The field of spatial analysis is a rapidly developing applied science. One area where this scientific approach can contribute to the analysis and interpretation of field sampling is in the study and distribution of pollen and spores. Pollen grains and spores have distinct spatial distributions that can be identified, analyzed, and modeled in association with significant environmental changes that have influence on resource appraisal and management. In this work the pollen is perceived as a regionalized variable and modeling procedures are used to reproduce spatial distribution patterns, and the continuity of pollen and spore data. As an example, we examine the spatial analysis of surface pollen rain from a desert environment in the Big Bend National Park region located in west Texas (Text-Figure 11).
