I work in educational and academic publishing, and in many contracts, the copyright belongs to the publisher, and not the author.
You are quite right. Some years ago I wrote all the copy for a children's guide to walking in the Lake District, Rocky Rambler's Wild Walks published by LDNPA. My contract with the publishers clearly stated that copyright on the words would be theirs whilst the illustrator, Colin Chapman who had created the eponymous cartoon character retained copyright on all illustration. Cicerone Press later published an updated reprint, and presumably have also acquired or share with LDNPA the text copyright.
As regards rock climbing, there is only a finite choice of accurate ways to describe a traverse or a corner, so I guess that plagiarism, or, to put it more kindly, quoting the original author's words should be seen as a compliment rather than a breach of copyright. Whole sections of my 1988 CC guide to N Devon & Cornwall were 'lifted', by David Hope, Brian Wilkinson and the editorial team for the 1998 edition: I was delighted!
Of course when rival publishers produce guides to the same areas care is needed to avoid plagiarism, but if you look at all the modern guides you will notice not only huge improvements in production values but many close similarities, and (though I may well be blackballed by the CC for saying so!) the kick up the arse that Alan and Rockfax gave the traditional publishers benefited the climbing community as a whole and that's what anyone involved in providing information for climbers should be concentrating on, not petty squables over the ownership of content.
To the OP: I can safely say from bitter experience, that no guidebook writer should take any FA description as gospel! That is exactly why there are so many teams of dedicated volunteers out there who check every new (and old) route description and re-write them whenever necessary. You might think your words for your new route are the bees' knees, but if you really want to keep them unchanged then write the whole guide and the best of British!
