Research MSc: Influence of the forest environment upon forest biodiversity (Task 5.3 of Resilient Forests Project)

Supervisors: Jon Yearsley (UCD)

Resilient Forest Project task lead: Niall Farrelly (Teagasc)

Research MSc. Project description

An ecosystem's biodiversity has been shown to promote the resilience of the services that ecosystem provides (e.g. Isbell et al., 2015; Grange et al., 2021). This graduate research MSc. will use existing data from Teagasc field surveys and data from the National Forest Inventory to quantify forest plant biodiversity in Sitka spruce plantations (from canopy to the forest floor). Using these datasets, we aim to develop a predictive model of Sitka spruce plantation biodiversity.

The research student will:

• be trained to work with biodiversity data and their analysis. Forest biodiversity will be quantified from several viewpoints (e.g. using species richness to accentuate the effect of rare species and Simpson’s index to focus on common species).
• combine the forest biodiversity data with environmental covariates, such as Met Éireann climatic data (1km resolution), landscape features (e.g. aspect and altitude), and soil properties. Spatial models that account for spatial autocorrelation will be used with the compiled database to find environmental conditions that are correlated with the highest forest biodiversity.
• estimate the effect of tree species identity and the interaction between tree species upon forest biodiversity. The impact of the tree diversity upon the broader forest diversity will be modelled using a diversity-interaction framework (Kirwan et al. 2009)
