Predicting the impact of environmental change on floral resources for pollinators at the national scale (FLOMAP)

Most flowering plant species need to be pollinated by animals to achieve optimal seed and/or fruit production. Pollination services provided by wild and managed pollinators are estimated to contribute €153 billion to the global economy and €54 million per year to the Irish economy (€3.9 million for oil-seed rape alone). However, many pollinator species are in severe decline and land-use change resulting in the loss of habitat and floral resources is a major contributory factor. Little is known about the current state of floral resource availability for pollinators across Europe and basic methods to describe and compare floral resources across landscapes are almost completely lacking. Thus, there is no system in place to predict the impacts of land-use change on pollinators. We propose to assess the quality of the dominant land-uses at the Irish national scale for pollinators using floral abundance and diversity as a proxy. We will use expert and citizen science surveys of flower abundance and diversity in selected grid squares as well as existing floral datasets. We will then create a floral resource heat-map (combining floral data with land-cover data, nectar and pollen quality data and known pollinator preferences for plant species) by modelling forage resource availability and suitability for pollinators and using Geographical Information Systems to map it across the country. This will elucidate which areas can provide adequate nutrition for pollinators and thus, for example, the potential to provide sufficient pollination services for nearby insect-pollinated crops. It will also help identify pollinator hotspots and areas that are in need of conservation efforts to improve pollination services, thereby making a significant contribution to pollinator conservation and agricultural sustainability. This project will provide a modelling framework that can be used across all European countries to assess areas of conservation priority for pollinators.

PhD research: The impacts of management and landscape context on plants and pollinators in intensive agricultural grasslands

I’ve recently set up an online citizen science project called Count Flowers for Bees. You can now help Irish bee populations by following these 3 easy steps: (1) Click on this link<>  (2) look at photos of flowery grasslands from across Ireland (3) count the flowers and then categorize them into simple groups.It’s easy, fun, possibly addictive and you don’t need any knowledge of flowers or to get off the couch. You can do as many photos as you like. Help me count flowers for bees!
