On September 23rd, Year 12 students took part in a Biodiversity Day at Epping Forest Field Studies Centre. In the morning, armed with pond nets, magnification pots and an identification key, students worked collaboratively to plan and complete an investigation to compare the biodiversity of two ponds, ensuring standardised techniques that represented the habitat. In the afternoon students investigated how the species of tree affected the biodiversity of invertebrates in a terrestrial habitat. The maintenance of biodiversity and the human impact of species diversity continues to be a worldwide issue, so it is essential to study this element of Biology for the A level course.
