Publications

Dahl's inventories of flora around Skara and Saleby, and some of the papers he wrote during as a student at Skara and Uppsala are in the Olof Knös Collection in the county library of Skara. The collection includes the minutes of "The Swedish Topographic Society in Skara" which contains some papers written by Dahl. Inspired by Linnaeus, Dahl wrote a Horologium Florae, a "flower-clock" of Skara, which was posthumously published in Ny Journal uti Hushållningen, in May–June of 1790. Olof Knös was the keeper of the minute-book and most probably published the article. Johan Abraham Gyllenhaal's collections in the university library at Uppsala also contain some papers written by Dahl.

On January 3, 1777, an excerpt from an anonymous letter was published in Inrikes Tidningar. The writer had, during a journey from Stockholm to Gothenburg in July 1776, visited "Himmels-Källan" in Varnhem. The letter describes the quality of the spring and 58 species from the swamp around it are. It is presumed that since Dahl often visited Varnhem and his friend Jonas Odhner that the letter came from him.

Dahl's only publication during his time in Gothenburg was a result of what was probably one of the first environmental-impact studies. Waste from the manufacturing of herring oil was a major problem, causing polluted water and sea bed organism death. Dahl was one of three members of a commission who studied the issue and wrote regulations regarding waste products from the try houses. This document was the first historical step towards a restriction of industrial waste in Sweden. Dahl's diary on the draggings in the archipelago of Bohuslän was published in Stockholm's Trangrum-Acten in 1784.

During his short time at Turku Dahl published his most important work: Observationes botanicae circa systema vegetabilium divi a Linne Gottingae 1784 editum, quibus accedit justae in manes Linneanos pietatis specimen (Kopenhagen, 1787).
