Biodiversity Targets and Successes

We have set a target to achieve Biodiversity Net Gain by 2032 against a 2018 baseline. Calculating that baseline developed our understanding of our estate and enabled the setting of targets around species and habitats.

Our ambitious Strategy has already delivered results, including attracting breeding barn owls, trialling different approaches to wildflower meadow creation, re-introducing Black Poplar, the rarest tree in the UK, and achieving ‘Platinum’ accreditation from Hedgehog Friendly Campus.

We are delighted that our Biodiversity work is being recognised and proud of recent awards we have won, including the Green Gown Awards (GGA) for the Nature Positive category – both a Finalist in the UK and Ireland Awards and Highly commended for the International awards.

We were also pleased to become one of founding members of the Nature Positive Universities Alliance which was established at the UN Biodiversity Conference (CBP-COP15) in Montreal, Canada. Read more about the Nature Positive Universities Network and the opportunities it brings to collaborate with universities global on nature restoration and preservation.

Recent Progress on our Biodiversity Strategy

Following the development of our biodiversity baseline looking at land categories and identifying species, University departments, including Estates and Facilities LINK and the Biosciences Department, have worked jointly to develop our Biodiversity Strategy and action plan.

The University has a series of environmental sustainability goals and performance indicators around our biodiversity goals, including:

1. Net gain of biodiverse habitats.
2. Enhancement of biodiversity through habitat creation schemes.
3. Engagement with biodiversity conservation.
4. To maintain or enhance the Estate’s current species richness.
5. To maintain or enhance population levels of priority species.

In the last year, we have recruited a dedicated Biodiversity Manager and worked hard to embed the Biodiversity Strategy’s delivery and continued to engage our staff, student and wider community.

Practical Actions

As an organisation, we have long undertaken much work to maintain and extend existing ecosystems and the biodiversity of both plants and animals, especially those under threat. 

Recently we have:

• identified all International Union for Conservation (IUCN) red-listed species, locally important and vulnerable species on site and have individual action plans for them all on maintaining or increasing priority species’ populations.
• undertaken improvement works to our lake at Van Mildert College. This project has seen our Grounds & Gardens Team remove over-grown vegetation, to allow the reintroduction of lower growing marsh species, rare in this part of County Durham.
• created a Wildflower Meadow Trial at the Botanic Garden. Working with Durham Wildlife Trust, this has seen the lawn transformed into a meadow, with different approaches to re-wilding trialled side-by-side, to judge their effectiveness. The trials have also been expanded to include trials at a number of our college grounds.

• Achieved Hedgehog Friendly Campus Platinum status as a result of work to implement improvements such as improved signage and regular litter picks. 

• Re-introduced Black Poplar (Populus nigra) the most endangered native tree in Britain. We nursed cuttings in our Botanic Garden, with planting out locations along the banks of the River Wear, and have kept some cuttings within the Botanic Garden so that they may be coppiced to harvest further cuttings for future conservation efforts. 

• converted 9 hectares of lawns to annually mown meadows, with substantial increases in plant richness, including creating new sites for Common Spotted, Bee, Marsh and Fragrant Orchids.
• altered land management and attracted Buzzards to breed in Durham City for the first time in at least 200 years.
• Enriched 4.3 hectares for our Botanic Garden with yellow rattle seed.
• planted out thousands of self-grown native wildflower plants, including introducing two locally-extinct wetland species, Skullcap and Water-Horehound.
• developed a spin-out company to grow locally-provenanced plant species to enhance university biodiversity and to revegetate local quarries and woodlands, working with Durham County Council and the National Landscape Partnership.
• integrated Nature Positive approaches into our core operations, for example our Botanic Garden took part in No Mow May, and our Grounds & Gardens Team have left fallen deadwood in situ to create habitats.
• completed a full Biodiversity Net Gain account of 1000 land parcels across our Estate, feeding into future estate and conservation planning,
• produced draft strategies for altered land management for net gain across 6 hectares.

Planning

Sustainability is a University transversal strategy and threaded through all that we do. We now include biodiversity within our own planning and development on the University’s Estate. Our Energy and Sustainability team and Biodiversity Delivery Group work with the Estates and Facilities Directorate Projects and Infrastructure Team to ensure we include local biodiversity into any planning and development process.

One example can be seen in our recently refurbished college residence, James Barber House where we used British native wildflower meadow seed mix for clay which will produce a naturally beautiful wildflower species and seven meadow grasses and our Mathematical Sciences and Computer Science development where we laid a dual purpose mix and wild bird wildflower seed which also included a good mixture of half a dozen grass species, providing annual flowers in the first year and perennials thereafter.

We are ensuring that any developments we make on our Estate uplift Biodiversity to ensure Biodiversity Net Gain.

Partnerships

We are working in several partnerships with local and regional organisations including Durham Wildlife Trust, the Wear River’s Trust and the Woodland Trust. We also participate in national and international networks to share good practice on our Nature and Biodiversity activities for the benefit of Durham and the wider world.

Education

As well as taking practical action, biodiversity study is incorporated into our taught modules, for example including how ecosystem services affect economics, the colonial legacy of many invasive species and the cultural importance of medicinal plants. It is also creating and supporting opportunities for biodiversity research from students and professors alike. Details of some of these courses can be seen at ESR - Durham University.

Additional modules include L1 Organisms and Environment; L2 Ecology module; L3 Conservation Biology module and L3 Field course modules: including modules on Tropical, Subtropical, Temperate and Marine ecosystems. Further details can be found in the Programme and Module Handbook: Undergraduate Programme and Module Handbook 2024-2025 - programmes for Biosciences

In addition, self-guided opportunities are also available and promote to our university community such as Mammalweb: Learn about Animals (mammalweb.org) and we deliver School Science Events, such as Celebrate Science event (Activities for 2024 - Durham University).  

Community Outreach

We also deliver community outreach and events on sustainable use and management of land, on biodiversity and priority conservation species, on conservation and restoration of land, as well as supporting land and aquatic ecosystems through education.

Our baseline audit and Biodiversity Strategy development has highlighted the species richness of our estate, with 983 different plants, birds, mammals and insects identified. We have shared key findings on the iNaturalist platform and delivered talks to key stakeholders and schools across County Durham.

We make available self-guided walking and biodiversity routes for staff and students such as Walking routes Oct 2024 - Durham University on social media and Want to explore your new campus? sharepoint pages.

We continue to take part in outreach with local school and communities, as well as with our own staff and students. Outreach highlights include hedgehog outreach sessions in local primary schools, purpose-built biodiversity games consoles at Science Festival, and leading staff/student biodiversity walks.

Research

Many colleagues are undertaking research involving local and national communities on sustainable management of land.

Colleagues within our Department of Biosciences, are working with small holder farmers in Zimbabwe to try and address issues of soil degradation that is impacting on crop yields.

Drought persistently confronts smallholder farmers and singly impoverishes millions of people in southern Africa. Severe soil degradation makes plants more vulnerable to water deficits, exposing crops to drought stress even when there is low rainfall. While the cause for this phenomenon had been attributed entirely to low water-holding capacity of degraded soils, breakthrough research by the Durham Centre for Crop Improvement Technologies (Chivasa Group) has shown that the soil microbiome plays a decisive role - they blocked drought stress damage in cowpea plants grown in a degraded Zimbabwean soil by replenishing it with a thriving microbiome. Soil fertility analysis of samples from degraded farms in Zimbabwe revealed critical deficiency of soil organic carbon, which is the key fuel required for growth of soil microbes.

We have been funded by Innovate UK, STFC, the Royal Society and private philanthropists to exploit this research by developing strategies to drought-proof smallholder farming. We are screening crop varieties for their responsiveness to the soil microbiome and exploring low-cost measures to boost soil biodiversity in agriculture.

Detailed Progress Updates

For detailed information on some of this education, outreach and collaboration, see examples below:

Our leading Professor for Biodiversity from our Biosciences Department, gave a talk to the Derwent Valley Environment Conference (Join the First Derwent Valley Environment Conference in Consett - Consett Magazine - Positive Local News for Consett, County Durham) and has given similar talks to industry.

We work collaboratively with Durham County Council, most recently  on the Local nature recovery strategy (Local Nature Recovery Strategy - Durham County Council).

Our Assistant Professor, Rebecca Senior, along with their PhD student did a podcast interview about rewilding and its potential to buffer species from climate change. 

Our newly appointed Biodiversity Manager has led guided walks through our mature woodlands promoting our conservation across our Estate.

We have also worked in partnership to run a Bioblitz event with the North East Fungus Study Group.
