Biodiversity plays an important role at the University. Our Colchester Campus is set in a former deer park on the banks of the Colne River. The grounds of the campus retain relict acidic grassland, a scarce habitat type. Together with taller grassland, scrub and lakes, these form a complex mosaic of habitats with an extremely rich invertebrate fauna.
The campus also contains rare coastal grazing marsh and many notable specimen trees, including oaks, redwoods and black poplars. There are 18 major habitats on the Colchester Campus.

Hedgehog numbers in the UK have declined by up to half since the year 2000. It is now estimated that there are fewer than 1 million left. By undertaking the actions listed below, the University of Essex has become a safe space for hedgehogs to thrive.
We will be completing a set of actions to make our Colchester campus a safe space. This includes:
Hedgehogs are nocturnal mammals and, if seen out during daylight hours, may be in trouble. If you see a hedgehog out during the day, contact the British Hedgehog Preservation Society on
01584 890801 for advice and (if required) details of your nearest hedgehog rescue.
