Author' note: This article is based on remarks made in February 1998 at the annual meeting of the Weed Science Society of America in Chicago. Those remarks were in turn based on an article, to be published in Spanish, titled “Es Antinatural la Manipulación Genética de los Animales?” The Spanish version will appear in the Proceedings of the Segundo Congreso Caribeno de Bioetica, University of Puerto Rico, Mayaguez, March 1998. It addresses the question of the engineering of animals; the focus here is the engineering of plants. Whether one considers flora or fauna, the unnaturalness objection raises the same cluster of concerns. Consequently, an assessment of those concerns need not vary significantly in turning from animals to plants.

In simple terms, a phytosociological survey is a group of ecological evaluation methods whose aim is to provide a comprehensive overview of both the composition and distribution of plant species in a given plant community. To understand the applicability of phytosociological surveys for weed science, as well as their validity, their ecological basis should be understood and the most suitable ones need to be chosen, because cultivated fields present a relatively distinct group of selecting factors when compared to natural plant communities. For weed science, the following sequence of steps is proposed as the most suitable: (1) overall infestation; (2) phytosociological tables/graphs; (3) intra-characterization by diversity; (4) inter-characterization and grouping by cluster analysis. A summary of methods is established in order to assist Weed Science researchers through their steps into the realm of phytosociology.
