This paper reports a study of 384 13-14-year olds' written responses to open-ended questions about their understanding of and relationship with "nature." Using constant comparative method the responses were coded, categorised and themed. Most students held scientific conceptions of nature (excluding humans) and a utilitarian relationship with nature, a predominantly anthroprocentric worldview. A small number held aesthetic conceptualisations and an intrinsic value relationship: an ecocentric worldview. A substantial number of students however were neither anthroprocentric or ecocentric but rather expressed a conception of and relationship with nature which reflected aspects of Bonnett's "human-related" relationship (Bonnett, M. 2004. "Retrieving Nature: Education for a Post-humanist Age." Oxford: Blackwell). The findings from this study challenge a simple binary approach in which students' environmental worldviews would be analysed as either predominantly anthroprocentric or ecocentric. Bonnett's "human-related" relationship to nature reflects a more complex view of the world. Analysis revealed interesting differences, however, between students according to their urban/rural location, gender and school type.
