Nitrogen Deposition and Heathlands
The main aim of this resource is for students to understand the impacts of anthropogenic nitrogen pollution on heathland plant communities. The resource provides practical, scientific investigations without the need to organise a field trip.
The resource is divided into three separate activities:
* Investigating the effect of nitrogen deposition on heather growth (dry mass).
* Investigating the effect of nitrogen deposition on the percentage cover of bracken and heather in lowland heathlands.
* Investigating whether nitrogen deposition affects the abundance of heather and bracken in heathlands.
* Investigating the effect of nitrogen deposition on heathland plant diversity and species composition.
The activities consider all aspects of scientific investigations from data collection techniques to statistical/graphical analyses. All activities utilise data from, or are based upon, genuine research that has taken place at the University of Nottingham.
This resource was written by Dr Lauren Gough and Dr Amy Rogers (Open Air Laboratories East Midlands, University of Nottingham).
