I have been publishing this blog since 2005. And I’ve written many posts on nature journal prompts. I’ve collected links to all the prompts posts below.
These nature journal writing prompts can be used as ideas for a few pages, a section or a whole notebook. These ideas can be used for a day, a month or many years. The topics can be used to inspire projects, essays, poems, drawings or taking photographs.
