New Research – Ask a Farmer

Pollinators are an important part of the world’s biodiversity, responsible for pollinating crops and wild plants, providing a valuable ecosystem service (Potts, 2010). Despite its importance, it is evident the global decline of the wild and domesticated species of pollinators (Potts, 2010). In Ireland, 30% of pollinator species are classified as threatened with extinction (Fitzpatrick et al., 2007), which jeopardises the country’s food production since the decline of pollinators means the decline of pollinator-dependent plant species (Potts, 2010).

78% of Europe’s flowering plants benefit from animal pollination, as do 71% of the crops that supply 90% of the world’s food.  However, modern agriculture contributes to the decline of pollinator species through the application of agrochemicals and the conversion to highly productive monocultures (Russo et al., 2022). In a country like Ireland, where nearly 70% of land is managed for agriculture, and the agri-food sector is one of the country’s biggest industries, contributing in 2020 with 7% of the country’s gross income, plus 10% of exports (Government of Ireland, 2021), this is a pertinent issue.

Figure 1: Hedgerow managed for pollinators in an arable farm in Kildare.

The decline of bees not only impacts human life with agriculture and food security, but also the entire ecosystem, as without their action, there is a decline in ecosystem services. It means that, for example, wildlife does not have access to fruits and seeds, which interferes with nutrient cycling, seed dispersal and adaptation to climate change (All-Ireland Pollinator Plan, 2021). Furthermore, pollinator conservation has beneficial effects on pest control, soil erosion and microclimate regulation, which helps to mitigate the effects of the climate crisis and biodiversity loss (All-Ireland Pollinator Plan, 2021).

According to Russo et al. (2022), it is extremely important to take conservation actions that protect the remaining high-quality habitats and improve the quality of degraded systems by identifying central organisms in the plant-pollinator network that can support the pair’s diversity and abundance.

A key challenge facing biodiversity conservation is human behaviour and the factors that govern its change (Marselle et al., 2020; Schultz, 2011; Knapp et al., 2020). However, Knapp et al. (2020) identified that when developing conservation strategies, natural scientists often disregard social factors affecting the human decision-making process to favour ecological evidence. This is particularly interesting because the implementation of conservation practices is majorly voluntary (Witzling et al., 2021) and, therefore, relies on a human decision.

Ignoring the social aspect of the conservation problem creates a gap between the ecological solutions and the implementation of these solutions by individuals, communities and society in general. This gap demands interdisciplinary approaches combining the understanding of the social pressures and norms that shape behaviour, the psychological reasons behind such behaviours, and the ecological solutions that can improve conservation behaviours.

Farms cover 67.6% of the Ireland’s area (EPA, 2022); therefore, taking into consideration farmers’ experience and knowledge of the land to adapt the already in place actions to a more comprehensive and user-friendly action plan is extremely important for a real impact in not only conserving the pollinators but also reversing the trend and restore pollinators in the country.

Ask a Farmer is a PhD research project that will contribute to closing the gap between farmers’ actions and the ecological solutions to reverse pollinator decline using the All-Ireland Pollinator Plan (AIPP) as a case study, expanding the traditional, evidence-based conservation research and increasing the uptake and perpetuation of the AIPP. Adopting a holistic perspective that acknowledges the diverse and plural values individuals and societies attribute to nature (IPBES, 2022), and understanding the wide range of social factors (beyond finance). These social factors shape farmer motivation, capabilities and opportunities, influencing their behaviour around pollinator interventions and policies.

This will be possible by first developing a socio-psychological model to identify and quantify the social factors, including historical context, well-being, finance, social norms and identity, influencing the behaviour of the farmers. Then, the social effectiveness of the pollinator-friendly actions proposed by the AIPP (figure 4) will be tested by evaluating what is being done in real-life farms, integrating the recommendations and the experience of a lifetime in the field. Finally, developing a strategy that integrates social and ecological perspectives to increase the number of farmers adopters of the AIPP, ensuring a continuation of the program and enhancing pollinator conservation in Ireland and beyond.

A very ‘beezy’ summer ahead!

Bees in the Trees

by Kate Harrington, PhD student, FOREST project, Trinity College Dublin

The pollinator community of young woodland sites, planted in farmlands under the Native Woodland Scheme (DAFM, 2024), was explored in the summer of 2023. We used pan trap and transect surveys to record and capture bees and hoverflies , looking at both the edges and centres of the woodlands, and we also looked at pollinator activity and floral resources. 

Pollinators, as might be expected,  forage mainly on the edges of the woodlands. The Native Woodland Scheme prescribes the planting of flowering species around the edges which support our native pollinator species, and seem to be particularly important for solitary bees in the spring.  The grassy edges, released from agriculture pressure, and unmanaged hedgerows, also contribute to the floral resources available for pollinators.

With a range of sites of different ages, we were able to look at how the pollinator fauna changed across the development of a woodland from an open habitat to one with a closed-tree canopy.

It has been suggested that functional groups such as pollinators may be particularly useful as ecological indicators.  With the rush to plant native trees as a solution to the biodiversity and climate crises, monitoring the success of these restoration initiatives is crucial, and we may need to look beyond simple habitat metrics (Marshall, 2024).  Our findings suggest that if we were to use pollinators as a monitoring metric for woodland sites, that bees may be a better indicator than hoverflies, as the latter respond more to landscape-level changes, while bees may better reflect any site-level changes.

RestPoll: Restoring pollinator habitats across European agricultural landscapes

Dr Sarah Larragy, post-doctoral researcher working on RestPoll, TCD.

We are making strides on our work as part of the Horizon Europe funded project called “RestPoll” (https://www.restpoll.eu). The name of our project, RestPoll, stands for “Restoring Pollinator habitats across European agricultural landscapes”. Among its 31 partners are both natural and social scientists from research institutions across Europe, alongside professionals from ministries, NGOs and businesses. Our partners represent 14 countries in Europe.

What is the goal of this project?

The mission of this project is to restore and increase connectivity between habitats for pollinators to help reverse the decline of these essential insects and the important pollinating services they provide. It also hopes to investigate co-benefits of pollinator restoration to various sectors of society as well as incentives and barriers (e.g. in policy) to pollinator restoration. In doing this, RestPoll will help fill the necessary knowledge gaps that will help to enable and support members of society to reverse pollinator decline.

How will we do it?

A core part of this project is to establish, in each participating partner country, case study areas that contain ‘living lab’ sites. With this network of living labs established, RestPoll will assess how actions taken to help restore pollinator habitats impact both pollinators and people alike.

What is a living lab? A living lab is a setting where “experiments, research, and innovation take place in real-life contexts, often involving end-users or stakeholders directly”.

Aligning with other Irish research:

RestPoll is aligned with, and part of, the Research Ireland-funded BiOrbic Bioeconomy Centre (https://biorbic.com/), specifically the Healthy Ecosystems Challenge. Healthy, functioning, biodiverse ecosystems underpin the bioeconomy, particularly in agricultural landscapes.

In addition, RestPoll is working with the FarmBioNet project https://farmbionet.eu/, which is a Farmer-focused Biodiversity and Agricultural Knowledge Network, which brings together stakeholders for researching, implementing and supporting Biodiversity Friendly Farming practices.

RestPoll Updates so far:

Establishing Irish Case Study Area:

Last summer, I began reaching out to farmers to see about monitoring pollinators on their farms. Many of the farmers had previously been involved in an EIP project called ‘Protecting Farmland Pollinators’ (NBDC, Project Manager Dr Saorla Kavanagh), and so were already taking actions to restore habitats for pollinators on their farms, including reduced hedgerow cutting, reduced pesticide use and having pollinator friendly trees, to name a few.

The summer involved many farm walks and chats over cups of tea with farmers to tell them more about the RestPoll project and, most importantly, to learn more about their perspectives on biodiversity conservation in agriculture. With the help of Research Assistant, Claire Kearney, and Erasmus+ student, Anna-Sonia Anastasiadou, a trial round of pollinator surveys was also carried out.

First Irish RestPoll Living Lab workshop:

In Sept 2024, we ran our first Living Lab workshop on a participating farm site in Athy. Among attendees were farmers, researchers and a representative from DAFM. Attendees received an overview of the RestPoll project and our plans and heard the reflections on the key successes of the Protecting Farmland Pollinators project from Dr Saorla Kavanagh, before delving into discussions around biodiversity conservation in agriculture. A farm walk also took place, led by our host Andrew Bergin, tillage farmer and Farming For Nature Ambassador. For a more detailed summary of this workshop and the discussions that took place, follow this link.

Watch this space…

This year, we will be conducting three rounds of pollinator and floral surveys on participating farms in the Co. Kildare region. Also on our pollinator monitoring team are PhD student Fernanda Azevedo and Moya Owens, research assistant working on the “Antenna” project. Over the summer, we also hope to trial out a rapid assessment tool with some farmers to help RestPoll develop an easy-to-use tool to quickly monitor pollinators. A second living lab workshop is also due to take place this Autumn, where we can update our Living Lab network on our progress.

Hiring researcher/project manager for pollinator monitoring project

THIS POSITION HAS NOW BEEN FILLED!

A highly motivated individual is sought to join the multidisciplinary team of ANTENNA “Making technology work for monitoring pollinators”, a European Biodiversa consortium nationally funded by the Environmental Protection Agency. The successful applicant will be based in the School of Natural Sciences at Trinity College Dublin, with Professor Jane Stout, collaborating with partners across Europe.

About the project

Due to pollinators’ decline and their importance in food security and ecosystems, the EU Pollinators Initiative has prioritised the establishment of a comprehensive monitoring system (EU PoMS). Modern technologies like robotics and computer vision can improve pollinator monitoring coverage, speed, and accuracy. However, more research is needed to advance and adapt these technologies to determine the best, most cost-effective ways to use them for pollinator monitoring.

ANTENNA will assess stakeholder needs regarding usability, design, current limitations, and opportunities for improvement to enhance new monitoring methods. Based on this, we will improve methodologies whilst testing their effectiveness and complementarity alongside traditional sampling across various regions within and outside the EU. Additionally, we will create a roadmap for improving pollinator monitoring across Europe using these frameworks, data standards, and integration pipelines.
