• About GiGL

    We work with service level agreement holders, customers and the public to meet a range of data needs. Our ongoing development has been shaped by our users since 1996.

  • Our Data Holdings

    Data is the core of everything we do. It is our life blood and our reason for being. Find out more about the data we hold, what you can do with it and how you can contribute to it.

  • Submit Records

    We encourage everyone to submit records knowing that not only will they be securely managed, but also that they will help inform decisions in London.

  • Access our Data

    Our data is available to all - whether you want to know what wildlife is in your back yard, need comprehensive data for a single site or you need to know everything about everything.

  • Planning

    Many of the datasets GiGL manage inform the planning process. Protected and notable species observations and designated sites information provide baseline data to consult as part of local decision making. These and other datasets can also feed into strategic planning at the landscape level.

  • Surveying & Recording

    GiGL's work would not be possible without the many recorders in London. These pages explain what happens to your records at GiGL and include some practical recording guidance.
