about the validity of the mark among Internet users who asserted there were senior uses of the mark in a more general context such as Mors Kochanski as early as 1981, however no formal opposition was ever filed, nor any assertion of continuous use in commerce as the mark related to Internet forums. As of 2021, Bushcraft USA has not publicly enforced its mark against other Internet forums using the term. Promoters The Irish-born Australian writer Richard Graves titled his outdoor manuals "The 10 bushcraft books". Canadian wilderness instructor Mors Kochanski published the "Northern Bushcraft" book in 1981 and an expanded edition of the book in 1988. He has stated on numerous occasions that book title was an explicit reference to Graves' work. The term has enjoyed a recent popularity largely thanks to Ray Mears, Cody Lundin, Les Hiddins, Les Stroud, Dave Canterbury and Mors Kochanski and their television programs.
