Gaia Guide: Field guide

Find field guides


Gaia Guide is a non-profit initiative, putting field guides in the hands of anyone carrying a smart phone or tablet. Access to the information on this website is and will remain free. Likewise, all field guides based upon this website are free.

Our goal

The goal is to make it easier for people to recognise the great variety of life around them and, through recognition, start to build an understanding of that life, its needs, its beauty, and its value.

Get started

If you are planning a trip to a region covered by a field guide on this website, download a suitable ready-made field guide or create your own custom field guide by downloading the Gaia Guide app and then selecting the set of field guides that you want to take with you into the field. Extensive information is available to help you create your custom field guide today.
There are gaps in species coverage, especially among the less charismatic and less common species. If you encounter a species that is not described on this site please consider using one of the mobile applications to record the details of your encounter. Use the app to upload those details to this site and to include any photos or audio recordings that you capture so that others with similar encounters can be assisted in future.
If you are doing a biodiversity survey in a particular region, also consider using Gaia Guide. Should the area or species of interest not already be covered by existing data, we can work with you to efficiently assemble suitable field guide data to support biodiversity survey work. All records gathered using our mobile applications are uploaded to this website. They can then be filtered, edited and reviewed online and are available for download by researchers in a variety of formats. If this interests you, please get in touch.
