Expedition 1 – biodiversity research in the Krka valley and diving in the Adriatic

Start date expedition 1: Thursday 14th June        
Length expedition 1: 2 weeks

This project has a waiting list

The first week of this two week expedition is spent in the valley of the Krka National Park. At this site you will complete a series of lectures about Balkans wildlife and conservation, whilst during the day you will work alongside a series of research teams. The projects include mist netting for birds and recording morphometrics, plumage and moult. Mammal surveys using Distance sampling and sand trapping. The valley houses some extremely rare and important species of snake such as the venomous nose horned viper, Vipera ammodytes, and the leopard rat snake, Zamenis situla, and these are surveyed using opportunistic searches along transect lines and from traps. Surveys are also completed for both native and invasive fish, using traps and electrofishing. Biodiversity surveys of some of the larger cave systems which are also home to the blind cave salamander, Proteus anguinus, are carried out by one of the teams.

In the second week, you will move to the oldest marine national park in Croatia on Mljet Island. During this week if you are not dive trained you will complete a PADI Open Water dive training course. If you are already dive trained or would prefer to snorkel this week you can complete the Mediterranean ecology and survey techniques course, with two lectures and two practicals each day (either by diving or snorkelling). Alongside these training courses students can assist with some of the research projects, such as estimating and monitoring fish populations and seagrass surveys.
