“Harriet has always been interested in working with animals. Through her studies of Biology at the University of Sheffield, she sparked her interest in the ecology sector when she planned and conducted a reptile survey for her degree at one of the Surrey Wildlife Trust sites. She joined the Ecology Services team in 2018, and is now an Assistant Ecologist who is confident in carrying out and assisting with surveys of protected species such as bats, badgers, birds, reptiles and great crested newts. She also has experience working on highways infrastructure projects as an Ecological Clerk of Works and an accredited agent under dormouse and great crested newt mitigation licences, in addition to writing reports on our suite of ecological surveys.
In her spare time, she can be most often be found walking around the Surrey landscapes with a camera or binoculars, looking for wildlife”

“Jenny has always loved wildlife she she can remember, however she has joined the Ecology Services team through a slightly unconventional route. First completing her Masters in Chemistry at Durham in 2014, her passion for all things wild (particularly invertebrates) brought her to Imperial College, where she graduated her MSc in Ecology, Evolution and Conservation with Distinction.
With a background covering multiple disciplines, Jenny has experience across a wide range of roles. Although at the start of her ecological career, she is skilled in Bat, Great Crested Newt and Reptile surveys, and has gained skills in Ecological Clerk of Works as well as Badger surveying and sett closures. Jenny is currently expanding her invertebrate knowledge (particularly butterflies and spiders) and is aiming to gain a class licence for Great Crested Newt in the near future. Outside of work, she likes arts and crafts, and is inspired by the wildlife around her.”
