More Pages, More Problems? Tracing the Rising Complexity of Conservation through Game Ranch Management

Conservation in southern Africa has become increasingly complex, requiring practitioners to operate across ecological, legal, economic, and sociopolitical domains. Through a longitudinal analysis of Game Ranch Management, a foundational textbook in wildlife conservation, this article traces how the field's knowledge base and professional expectations have expanded over time. Since its first edition in 1989, the textbook has grown from a 672-page technical manual to a 1012-page interdisciplinary reference, mirroring the profession's shift from land-based management to multidimensional governance. Drawing on systems theory, governance scholarship, and the sociology of professions, this study treats the textbook as an institutional artefact that encodes changing norms, values, and competencies. The results show progressive content expansion, disciplinary broadening, and the incorporation of governance, economic, and ethical frameworks, reflecting conservation practitioners' increasing cognitive and administrative load. The findings highlight how conservation's increasing complexity reshapes training curricula, institutional design, and practitioner identity in resource-constrained contexts, offering a novel, text-based approach for understanding professional and epistemic change in applied environmental fields.
