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
Horndean is a rural English village and civil parish in Hampshire located half way between Petersfield and Portsmouth.
To achieve these aims we work closely with Horndean Parish Council and local people to
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Study historical documents and past surveys in order to detect changes in the local landscape, habitats for wildlife and species;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.

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.
Biodiversity Action Plan
A Biodiversity Action Plan is an internationally recognized program addressing threatened species and habitats and is designed to protect and restore biological systems.
The BAP explains what biodiversity is and why it is important to preserve it for the future of all living things.
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

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
The previous year's AGM was followed by a talk from Adrian Bicker about
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
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
which enables survey results to be recorded on a computer tablet and loaded directly onto the website.
organised by Horndean Parish Council's Countryside Team supported by the Horndean Biodiversity Group is being held on
A BioBlitz is an intense biological survey over a continuous time period, usually 24 hours, by groups of scientists, naturalists and volunteers to try and identify and record all the species living in a designated area.
over 24 hours on Friday 7th and Saturday 8th July to identify the wildlife currently living on this site.
Full details of what the event involves are set out
in the attached Flyer.
Everyone will be welcome to come along at any time during the event and get involved or to see what we are doing.
Catherington Down is a Site of Special Scientific Interest covering 32 acres of chalk grassland with remnants of ancient semi-natural woodland.
It has a high concentration of rare wild flowers such as Round-Headed Rampion, Pyramidal Orchid and Wild Thyme.
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.
Hazleton Common Local Nature Reserve is located between the A3(M) and Hazleton housing estate. It follows the motorway south from the Horndean junction to Waterlooville Golf Course and the boundary with Havant Borough.

Hampshire Biodiversity Information Centre
The Hampshire Biodiversity Information Centre (‘HBIC’) is an initiative hosted by Hampshire County Council to bring together and collate and manage information about Hampshire’s wildlife and natural environment and disseminate it to those who need it.
Supporting Wildlife in Our Own Gardens
