A Landmark Report: The State of Nature 2024 for Guernsey Bailiwick Unveiled

In a significant step toward understanding and protecting the natural environment, the Guernsey Nature Commission has released its first-ever State of Nature Report for the islands of Guernsey, Herm, Sark and Lihou. Like many jurisdictions who do this, the report provides a detailed look at the current state of biodiversity across our islands, offering a critical benchmark for future conservation efforts. We’ve read the report and summarised it but you can read the full report here. 

As Lieutenant General Richard Cripwell CB, CBE, patron of the Nature Commission, stated in the report: “We are reaching a crucial point in the struggle to conserve our wildlife and wild spaces, and our actions now will define the state of nature for years to come.”

A New Chapter for Nature Conservation

The report highlights the vulnerability of Guernsey’s wildlife. It is the product of extensive research and collaboration among scientists including our own Dr Miranda Bane; passionate conservationists like CI county butterfly recorder Andy Smith, and local organizations like ourselves. The report sheds light on the poor condition of various habitats and species, and calls for greater input into providing data that will guide the future environmental policies and initiatives needed to safeguard nature here. The Nature Commission has said it hopes that this report will serve as a foundation for positive environmental change across the islands as nature plays a pivotal role in our own prosperity and wellbeing, making its conservation essential.

Why This Report Matters

Islands like Guernsey are known for their rich biodiversity, but we also face unique challenges. With our small amount of land available to nature and fragile ecosystems, islands are particularly vulnerable to the global biodiversity crisis. The State of Nature 2024 report highlights these challenges, noting alarming declines in biodiversity worldwide and emphasizing the urgent need for more local action to protect species and habitats.

Key Findings from the Report

– Habitat Loss and Degradation: The report reveals that natural habitats, such as coastal grasslands, marshy grasslands, and woodlands, are under threat, with significant losses recorded over recent decades, specifically natural terrestrial habitats in Guernsey have declined by 63% since 1999, which are a major concern for biodiversity.
– Species at Risk: Certain species, terrestrial mammals, amphibians, reptiles, birds, and marine life, are facing pressures from habitat loss, climate change, and invasive species like Asian Hornets. We would add bees and butterflies to this list too – as we have seen their decline and would not want these vital pollinating insects go the way the 80-plus species of plants and animals thought to have become extinct in Guernsey in the last century.
– Climate Change and Human Impact: Rising temperatures, pollution, and unsustainable land use practices are identified as major drivers of change. We agree with and applaud the report’s calls for more robust action to mitigate these impacts.
– Invasive Species: The arrival and introduction of non-native species, such as the brown rat, Asian Hornet and sour fig, is highlighted as a key threat to native wildlife.

Next Steps: What Can Be Done?
The State of Nature 2024 report doesn’t just outline the challenges; it also offers a roadmap for positive change. By identifying key gaps in knowledge and providing evidence-based recommendations, the report is a call to action for both policymakers and the general public.

1. Habitat Restoration and Protection – Many of our natural habitats, such as grasslands, woodlands, and coastal areas, are in decline. Protecting and restoring these ecosystems is critical to preserving biodiversity.

– Enhancing Land Management: The introduction of sustainable land management practices is crucial. This includes better grazing strategies to prevent overgrazing or undergrazing, both of which can harm biodiversity. For example, the Guernsey Conservation Herd has been working to manage local grasslands through controlled grazing, helping maintain healthy ecosystems.
– Reforestation and Tree Planting: Increasing woodland cover is another key strategy. With only 8% woodland cover (lower than the UK average), there’s significant potential for expanding and enhancing woodlands here. Initiatives such as Guernsey Trees for Life, which has planted over 1,400 native trees and hedging plants, demonstrate how local efforts can make a tangible impact. Expanding such programs will help restore habitat for wildlife, sequester carbon, and combat soil erosion.
– Coastal habitats are some of the most biodiverse areas, and they provide essential protection from storm surges and erosion. Restoring coastal grasslands, heathlands, and dunes can protect against climate change impacts and provide habitats for endangered species. For instance, controlling invasive plants like Sour Fig is crucial for the recovery of these habitats.

2. Tackling Invasive Species, one of the most significant threats to native biodiversity on islands. Some critical steps include:

– Early Detection and Rapid Response: Establishing monitoring programs to quickly identify and control new invasive species before they become widespread.
– Eradication Programs: Building on successful global examples, we can implement more ambitious eradication efforts.
– Public Awareness and Involvement: Community involvement is essential for preventing the spread of invasive species. You can help by reporting sightings of invasive species or participating in volunteer removal programs.

3. Climate Action.
Climate change is a significant driver of biodiversity loss, and its impacts are already being felt here.

– Reduce Greenhouse Gas Emissions: Although we live on a small island, we can contribute to global climate efforts by reducing carbon emissions. Installing renewable energy, improving energy efficiency in buildings, and reducing reliance on fossil fuels are all part of a holistic approach.
– Nature-Based Solutions: Using natural habitats to mitigate climate change impacts is a key recommendation. Coastal habitats such as salt marshes and eelgrass beds act as carbon sinks, absorbing large amounts of carbon dioxide. Protecting and expanding these habitats helps combat climate change while also supporting biodiversity.

4. Sustainable Land use.
Development and land-use changes are placing immense pressure on habitats. The State of Nature 2024 report calls for better planning and policies to ensure that development is sustainable and minimizes harm to biodiversity
– Strengthening Environmental Regulations: Ensuring that developments undergo better environmental impact assessments to prevent habitat destruction. The report emphasizes the need to enforce policies that protect Areas of Biodiversity Importance (ABI) and Sites of Special Significance (SSS), especially in marine areas that currently have minimal protection.
– Sustainable Agriculture: Agricultural practices need to balance food production with biodiversity conservation. The use of pesticides and fertilizers should be minimized to reduce pollution and maintain healthy ecosystems. The introduction of more sustainable farming techniques, such as crop rotation and organic farming, will protect soil quality and biodiversity.

5. Expanding Citizen Science and Education
Empowering locals to engage with nature is one of the most effective ways to foster long-term conservation. Citizen science like our app Bumblr and our schools education programs involve people of all ages in biodiversity monitoring and protection efforts.
– The Guernsey BioBlitz, where local residents help survey wildlife, can be expanded. This helps build a large database of local biodiversity while engaging the public in meaningful conservation activities.
– Environmental Education in Schools: Integrating biodiversity and climate education into school curriculums is essential for building a generation that values nature. Local schools can include lessons on Guernsey’s unique ecosystems, the threats they face, and ways to protect them.
– Community Outreach and Events: Hosting more nature-related events, workshops, and guided tours can raise awareness. Watch this space.

6. Supporting Conservation Organizations
Conservation efforts – by people like us (who all volunteers) need funding, expertise, and manpower. By supporting local conservation organizations—whether through volunteering, donations, or advocacy—you can help ensure that vital efforts continue and expand. Every year we spend five figures on providing art sheets to schools, ID leaflets, seeds to anyone who wants them, plus normal running costs like web and email hosting and insurance so are hugely appreciate of corporate sponsorship, most recently from Mourant – and private donations. If you’d like to donate, we have a Giving.gg page.   

7. Filling Knowledge Gaps
Finally, the report emphasizes the need for more research and data collection. Many species and habitats in Guernsey and Herm are still not well understood, and there are significant knowledge gaps regarding how best to protect them. More consistent data collection will allow for better decision-making and more targeted conservation efforts. Check out our science programme here.

– Long-Term Monitoring Programs: Establishing monitoring schemes to track changes in species populations and habitat conditions over time is essential. This allows for timely interventions and helps measure the success of conservation efforts.
– Collaborating with Universities and Research Institutions: Partnerships with academic institutions can lead to more in-depth research on local biodiversity, particularly in areas where data is currently lacking, such as marine ecosystems and understudied insect species.

Together We Can Make a Difference

The State of Nature 2024 report makes it clear: we all have a role to play in protecting the natural environment of Guernsey and Herm. Whether through getting involved in local conservation projects, or advocating for stronger environmental policies, everyone can contribute to preserving the islands’ unique ecosystems for future generations. By coming together as a community, it’s possible to reverse some of the damage and ensure a thriving natural world for years to come.
