He started his journal on October 22, 1837, just a few days after his graduation from Harvard. He wrote in it nearly every day until November 3, 1861, seven months before his death on May 6, 1862.
Henry David Thoreau stopped writing specifically for publication around 1852 and focused on creating his journal which grew to 14 volumes. His essays such as “Walking”, “Autumnal Tints” and “Wild Apples”, were drawn from these journals. They published these essays in the book Excursions.
In speaking about a poet, he said: ” Is there any other work for him but a good journal?” (Journal, vol. X, October 21, 1857, #115)
Reading his journals provides inspiration for our own nature journal writing. Free ebooks of some of Thoreau’s are available on Project Gutenberg.

Thoreau’s Style of Keeping a Nature Journal
After 1850, going on long nature walks and recording his observations became the central task of his life. He grew into an expert naturalist and it filled his life with learning and living well in the land where he lived.
He took walks in the afternoon and wrote notes in a field notebook.
Each morning or at the end of several days, he would enter his entries into his journal. Some entries he would rewrite or polish into essays or lectures.
He recorded, as he said, everyday phenomena so people could see how wonderful their world was.
He used his journal to record his observations of the life cycle of plants, the sequence of plant blooming (phenology), animal behavior, the weather, and other happenings.
He made very simple sketches and maps to illustrate an observation or an event.
Henry David Thoreau’s journal is filled with simple nature essays, character sketches, news events, stories, quotations and snatches of conversations, along with his social commentary on human society.
He used all this raw information to write essays and lectures. He had learned from experience that lacking well-detailed notes made recalling information and writing an essay later a headache.

What He Said About Nature Journal Keeping
“My journal should be a record of the things that I love” and then “I love nature, I love the landscape because it is so sincere. It never cheats me. It never jests. It is cheerfully, musically earnest. I lie and relie [sic] on the earth.” (Journal, vol. 2, November 16, 1850)
“The forcible writer stands bodily behind his words with his experience. He does not make books out of books, but be has been there in person” (Journal, vol.3, February 3, 1852)
