Jenkins did colour photography for his wife's non-fiction work ''Trees of Southern Africa'' (1972).<ref name="Generations" /> The couple travelled over 100,000 miles to research this three volume work.<ref name="Veldtrust (1972)">{{cite journal|last=Robertson|first=T.C.|title=Karoo Girl from Plains of Camdeboo Writes — A Tree Book to Wonder At|journal=Veldtrust|publisher=National Veld Trust|year=1972|page=16 (54)}}</ref> They subsequently collaborated on the 1978 travel book ''The Companion Guide to South Africa''. Helene Moore of the [[Knight Ridder]] syndicate believed that it was "impossible to cram everything pertinent into one guidebook and do a thorough job of it," but felt that the authors have chosen "the right solution." Moore claimed that the over four-hundred page book gave the authors sufficient space "for single-minded reporting on what to see at the bottom of this exotic continent - plus plentry of space for history, legend and all the personal commentary that enriches any travel book. Good reading even if you're not headed that way."<ref>{{cite news|last=Moore|first=Helene|title=Trips Should Be Fun: Guidebooks Can Get You In Right Frame of Mind|newspaper=[[Evening Independent]]|location=St. Petersburg, Florida|date=22 April 1980|page=11A|url=https://news.google.com/newspapers?id=kGFQAAAAIBAJ&pg=6303,1836053&dq=companion-guide-to-south-africa&hl=en}}</ref>
