About this mock
This mock examines advanced forensic botanical competencies centred on the identification of controlled and scheduled plant species, the integration of multi-disciplinary botanical evidence in scene reconstruction, expert witness obligations, and the quality-assurance frameworks that govern forensic botanical laboratories. Questions draw on plant anatomy at the cellular and tissue level, chemotaxonomy, microscopic identification criteria for Cannabis, opium poppy, coca leaf, psilocybin fungi, and khat, as well as the Daubert and Frye admissibility standards that govern expert botanical opinions in criminal and civil proceedings. The ISO 17025 accreditation framework, UNODC technical guidelines, the role of herbarium and pollen reference collections, and the requirements of proficiency testing schemes are tested alongside the forensic botanist's duties as an independent expert.
This mock is designed for students, MSc and BSc learners, and practitioners of forensic Forensic Botany and Palynology who need to demonstrate precision across integrative casework scenarios. The questions are calibrated at hard difficulty, meaning distractors differ from the correct answer on one precise anatomical feature, one numerical threshold, one statutory provision, or one procedural step. A solid command of the primary literature, UNODC guidelines, and established forensic botanical textbooks is expected.
Topics covered:
- Cannabis anatomy and THC threshold distinctions for hemp vs drug-type plants
- Microscopic identification of opium poppy, coca leaf, and khat alkaloids
- Psilocybin mushroom identification by spore morphology and colour tests
- Multi-discipline casework integration: palynology, wood anatomy, plant DNA
- Evidence flow and exhibit continuity in botanical casework reconstruction
- Expert report structure and uncertainty expression under Daubert and Frye
- ISO 17025 accreditation and verification requirements for botanical laboratories
- Pollen reference collection standards, proficiency testing, and z-score criteria
Allow 30 minutes.
