Biography

I work with landscape monitoring, including research on the development and use of indicators of landscape spatial structure, biological diversity, cultural heritage and public accessibility and landscape preferences. My main research interests are linked to analysis of how human use of natural resources affects landscapes and influences different qualities in the landscape, including ecosystem services. I work with GIS and spatial analyses, recording in the field (habitats, plants, bumblebees, butterflies, cultural heritage and landscape characteristics), and combine different types of data to monitor developments in landscapes and their qualities.

Abstract

In modern agricultural landscapes, «the green in between» plays a crucial role in supporting the survival of many plant and animal species. These areas include field margins, grassy banks between fields, mid-field islands of uncultivated vegetation, rocky outcrops, fallow land, and other patches of unused ground. We surveyed vascular plant species in these green spaces and compared the results with a similar survey conducted 18 years earlier. Our findings reveal a general decline in species richness, including many plants important for pollinators. Nevertheless, numerous green patches remain species-rich and continue to provide valuable resources for pollinators. Among these, road verges stood out as the most diverse. This suggests that active management of the green in between—such as removing invasive species and implementing regular mowing to maintain flower-rich patches—could significantly enhance its value for wildlife and biodiversity conservation.

Abstract

This paper outlines the rationale for, and the current state of, mapping habitat diversity. It provides an overview of progress in assessing and monitoring farmland habitat biodiversity at the national level, in line with the proposed OECD Farmland Habitat Biodiversity Indicator (FHBI). The paper describes pilot studies by eight countries, summarising the approaches to mapping habitats, assessing habitat quality, and implementing the FHBI at the national level. Drawing from the experience of the FHBI pilot countries, this paper offers general guidelines for defining habitats and assigning biodiversity values of habitats for calculation of the FHBI. It provides guidance on selecting the appropriate tier level for data acquisition, processing, and reporting, and summarises strengths, weaknesses and opportunities of the current FHBI structure used in the pilot studies.
