Ecology Fieldtrip
The ecology trip took place on 8th June, where at 10.00am we were introduced to the aim of our investigation: “The investigation of a named environmental factor, on the abundance of a species”. Within the Tillingbourne River, near Dorking, we investigated a series of organisms such as non-biting midge larvae, crane fly larvae and swimming midge larvae (just to name a few). We had been given a wide range of equipment at our disposal for investigating a variety of factors such as temperature, pH and velocity of the river. Equipped with our waterproofs and wellies, we trekked into the shallow river and began our pilot study.
Once we established that there was in fact the species we were looking for, everyone split into smaller groups and investigated the environmental factor which they believed to be the most significant. Our group was investigating the impact velocity a river had on the abundance of non-biting midge larvae.
Despite, sun-burn and a lost phone being the bane of our existence (it turned up), we prevailed in the end and had a lovely day out that enabled us to develop a greater understanding of what we had learnt within class over the previous two months and the practical application it can have in the real world!
