What happened to the holly leaf-miner?
Summary of the investigation
Holly trees are common in city squares and urban parks. In this investigation, students collect evidence of the food chain of the holly leaf-miner, studying energy flows through population numbers.
Animals are usually so transitory in feeding that it is impossible to assess the ecological impact of each species on its food source. However, the holly leaf-miner food chain provides an opportunity to study living organisms in the field and gain experience of ecological interactions in greater detail.
Full support is given for pre-visit work at school, data collection in the field, and post-visit work at school to put the fieldwork in its wider context. Extensive teacher guidance, with PowerPoint presentations, a full sample risk assessment and detailed plan of a sequence of lessons, are also available for download.
