Abstract
|
Aquatic landscapes have changed dramatically due to threats posed by anthropogenic activity, and most systems are in decline. Combating this necessitates the use of aquatic restoration and conservation techniques. In order to understand system decline and establish baseline conditions, palaeoecology is an often-used technique as past species assemblages can be used to infer past environment and ecosystem conditions. Traditionally palaeoecology has set conservation goals based on records from a single lake or river, whereas modern conservation focusses on the catchment scale; therefore, in order to bring palaeoecology in line with current conservation trends research should be performed at the catchment scale. This can be achieved by taking multiple samples from palaeochannels, lakes and ponds across a catchment, analysing indicators such as macrofossils and diatoms to build a holistic spatial and temporal picture of ecosystem change over time. This approach allows a range of unique questions to be asked and would better inform conservation and management decisions. The study site used to test the approach will be the River Glaven catchment, north Norfolk, where which has a wealth of contemporary species distribution information and a complex network of streams, ponds and lakes that provide many potential investigation sites. |
