Exploring the influence of the Ellenberg Nitrogen Index on oak growth across latitudinal gradients in Sweden

This project seeks to understand how soil nutrient levels, specifically nitrogen as indicated by the Ellenberg Nitrogen Index, affect the growth rates of oak species across Sweden. We use dendrochronological methods to elucidate the relationship between nitrogen availability and the growth of Quercus robur and Quercus petraea along a north-south gradient. This investigation highlights the significance of nitrogen in tree growth. It provides insights into how environmental factors such as latitude may influence oak development, crucial for forestry and conservation planning under changing climatic conditions.
