Sara Ruas

Post-doctoral Researcher

Research Interests

Agro-ecology, agro-biodiversity, plant ecology, spatial analysis and spatial statistics, landscape ecology, ecosystem services.

Current Projects

I am currently working as post-doctoral researcher on the HNV FarmForBio project under Dr. John Finn and Dr. Daire Ó hUallacháin supervision. My main tasks include:
a) developing a framework to identify HNV forests in Ireland
b) developing a repeatable, transparent and objective GIS methodology to estimate the national distribution of HNV forestry
c) identifying HNV forest Typologies
d) assess the potential for future improvements for estimating the national distribution of HNV farmland
