Caring for Horndean’s Wildlife by Sustaining Biodiversity

What is Biodiversity?

Biological Diversity, commonly shortened to Biodiversity, refers to the variety within and between all species of plants, animals and micro-organisms and the multitude of different ecosystems within which they live and interact.

Why is it Important?

All species, including us, depend on other species and so maintaining biodiversity is fundamental to their survival. We rely on the interaction between the different organisms that maintain the global ecosystem for fresh water, food, fertile soil and clean air, as well as natural resources such as wood, rubber and products derived from animals.

Biodiversity also helps regulate the growth cycles of plants, the mating seasons of animals, and even weather systems.

The Horndean Biodiversity Group

The Group was set up by local volunteers to observe and record our wildlife and to raise awareness of its diversity and importance.

It also encourages community involvement in the maintenance and development of wildlife habitats in including gardens, parkland, allotments, trees, the urban environment and Conservation Areas.

To achieve these aims we work closely with Horndean Parish Council and local people to Robin DH

  • Identify and record the natural resources and history of our local area;
  • Survey and identify local habitats and species;
  • Encourage and support community involvement in habitat and species recording and monitoring;
  • Raise local awareness and involvement in biodiversity conservation;
  • Study historical documents and past surveys in order to detect changes in the local landscape, habitats for wildlife and species;
  • Produce reports of surveys and activities of the group and record species on a database.

    We review and update the Group's plans and objectives regularly to ensure that we focus on the current most important issues.

    If you belong to a local Group who would be interested in seeing a presentation about our activities please contact us at this email address.

    Biodiversity Action Plan

    In 2014 the Group issued a ('BAP') for Horndean Parish which it had drawn up with the assistance of the organisations and individuals listed at the end of the publication.

    The BAP explains what biodiversity is and why it is important to preserve it for the future of all living things.

    Lovedean Field DH It also contains details of the many different species of animal and plant life that can be found within the Parish and the habitats in which they can be found, including several sites designated for nature conservation.

    Most importantly, the BAP sets out what we need to do to conserve, manage and improve our local wildlife habitats, including those in our own gardens, to support the many rare and important species that depend on them.

    It also includes cross-references and links to further information and other publications.

    The BAP can be viewed or downloaded as a PDF file by clicking on Horndean BAP.

    Activities and Events

    The 2016 AGM was held in Napier Hall on Tuesday 12th April at 7:00pm. Everyone who is interested in our activities was invited to the meeting which included presentations about some of our recent projects. Details of what the meeting covered are set out in the attached agenda and minutes.

    The previous year's AGM was followed by a talk from Adrian Bicker about Living Record which is a website that provides users with their own records system and gives access to a selection of distribution maps. Details of the wildlife found in a particular area are entered in the section of the website covering that location. These records are reviewed and passed on to local record centres and organisations working for conservation who use them to Blue Tit DH understand species distribution and population trends, identify key sites and habitats, and develop conservation plans. An alternative to Living Record which is used by the Parish Council Countryside Team for managing and sharing wildlife records is iRecord which enables survey results to be recorded on a computer tablet and loaded directly onto the website.

    A meeting looking at local wildlife caught on camera in 2017 will be held at St Wilfrids Church in Cowplain on 18 April 2018. Local naturalists, recorders and photographers will show pictures of amazing plants and animals seen locally, many at the Bioblitz on Catherington Down in July. The agenda for the meeting will be posted here and on our Facebook page as soon as it has been finalised.


    The 2017 organised by Horndean Parish Council's Countryside Team supported by the Horndean Biodiversity Group ran from 1pm on Friday 7th July to 3pm on Saturday 8th. This year's event was held on to record and explore the diverse wildlife currently living on this site. There was a great turn out of people both young and old who came along to get involved, and numerous species including over 200 moths were seen and recorded.

    The activites carried out over the course of the event are shown below.

    Friday Start Saturday Start
    Butterfly walk 1:00pm Bird watching 8:00am
    Bug/mini beast hunt 2:30pm Moth count & Trail camera results 11:00am
    Tree trail 4:00pm Bug/mini beast hunt 11:30am
    Trail camera set up 6:30pm Wildflower meadow survey 12:00pm
    Moth trapping 7:00pm Butterfly walk 1:30pm
    Bat walk 8:00pm

    A review of the day and a list of the species that were identified are shown in the attached Bioblitz Report.

    This year's BioBlitz follows last years event held on for which many members of the public joined us to see and record over 160 wildlife species including adders, slow worms, grass snakes, newts, bats, and an assortment of butterflies. Small groups walking the Common during the day also spotted a variety of wild flowers and native trees, and many species that live in water were found by the people doing pond dipping. During the night, a party equipped with bat detectors lead by Nick Knight from the Hampshire Bat Group identified many pipistrelle bats near the pond, and later on the moth traps attracted a good number of these nocturnal insects.

    Horndean's Trees

    The large number and variety of young and established trees that we have in Horndean contribute greatly to the landscape; however, trees provide us with a great deal more than just a pleasant environment.

    Trees are the biggest plants on the planet and are vital to the wellbeing of numerous if not all species. They produce oxygen and absorb carbon dioxide as they grow and the carbon that they store in their wood helps slow the rate of global warming.

    Young trees provide habitation and food for many communities of birds, insects, lichen and fungi while the trunks of ancient trees provide the hollow cover needed by species such as bats, wood boring-beetles, tawny owls and woodpeckers. One mature oak can be home to as many as 500 different species. Merchistoun Oak

    The canopies of trees trap dust and absorb pollutants and their roots help prevent flooding by absorbing thousands of litres of storm water as well as combating soil erosion. Accordingly, every tree you plant or preserve can make a real contribution to our biodiversity as well as the landscape.

    Information about the history of our trees and ancient woodlands can be found on John Vigay's website.


    In July 2016 we carried out a pond survey on Hazelton Common with the Horndean Parish Council Countryside Team. Details of this event are described on the attached page.

    Lists of moths seen in Horndean during surveys carried out in the last two years can be viewed or downloaded as a PDF file by clicking on Moth Species Survey.

    Details of protected and notable species that have been found on Catherington Down, Catherington Lith and Parsonage Field are contained in the datasets maintained by ('HBIC') which can be viewed or downloaded as a PDF file by clicking on Local Species Records.

    Supporting Wildlife in Our Own Gardens

    Some of the things we all can do to attract and support wildlife in our own gardens for our mutual benefit are set out on the My Garden page.
