This section of AlgaeBase contains information on the distribution of the species. It is being updated at present and is growing every day.

Click here to view a graphical representation of the progress to date. If you pass your cursor over each country you will get a species-record count for that country.


To get a list of distributional records, select "Region" (e.g., Europe, North America, etc.) or select Geography (such as Canary Islands, Azores), OR a country (such as, France, Spain). The data can be downloaded in a number of formats (e.g., Excel, text file). You can also select the Habitat and restrict the download to a particular class (e.g. Phaeophyceae) from drop-downs that will appear. If you use this information, please treat us fairly and cite the source. It helps when we seek funding. About 200,000 records have been entered, but the task is still very incomplete, particularly for non-marine algae.
