Articles in JEM inform readers about innovative approaches to sustain- able ecosystem management. Aimed at decision makers in the policy, management, and operational realms, as well as practitioners, professionals, researchers, and natural re- source users, JEM extends research results, management applications, socio-economic analyses, scholarly opinions, and operational and Indigenous knowledge. JEM Perspectives are reviewed by one extension specialist; Extension Notes, Discussion Papers, and Re- search Reports are reviewed by one extension specialist and two external peer reviewers from the natural resource community. Articles first appear in the online “Issue-in- Progress”; when online issues are full, articles are compiled into print issues (available by subscription). Submission Guidelines for authors are included at the back of this issue. To obtain subscription information and to view current and archived issues of JEM, see our website at http://jem.forrex.org . About the Publisher Forrex is a charitable organization focussed on promoting, supporting, and facilitating co-operative extension, technology development, and research ventures to support inno- vative and adaptive approaches to sustainable natural resource management.

JEM Vol 13, No 3 JOURNAL OF Ecosystems & Management Editor-in-Chief’s Report Editor-in- Chief’s Report Don Gayton ne of the great challenges of writing—and editing—a scientific paper is finding the right balance between methods and results. These two elements are the inter- Otwined Yin and Yang of communicating science. Each depends on the other. An overly brief and sketchy methods section throws doubt on the validity of the results. At the other extreme, too much technical detail and discipline-specific jargon in the methods section will drive readers away before they get to the results. Certainly other parts of an article are important, but methods and results stand at the very core of the document. They must each be carefully weighted with reference to each other, so the article finds the sweet spot between detail and readability. I wish there was a magic formula for achieving this balance, but the world of science and science writing is far too complex for a cookbook formula to be of any use. The other key element of a scientific paper is its figures—graphs, tables, maps, and photos. With the advent of digital publishing, photos, and maps have suddenly come alive, with full colour photos, slick overlays and high-resolution satellite imagery. But for me, the essence of a scientific paper is the graph. One good graph is worth a thousand words. In fact, the human brain seems to embrace visual information much more firmly than the same information conveyed verbally. I am a great fan of Edward Tufte, who has been described as “the Galileo of scientific graph- ics.” In his book The Visual Display of Quantitative Information (www.edwardtufte.com) he urges us to look closely at how we present our graphs and to get rid of extraneous and dis- tracting “chartjunk.” Tufte’s books are full of examples of truly excellent (and truly terrible) graphs, reaching back into history and forward to the present day. Tufte is surely the poet of the graph. The writer of the scientific journal article has an enormous challenge. He or she must synthesize months, years, or even decades worth of work into a comprehensive, well-ref- erenced, and highly condensed article and then submit to the often humiliating rigors of peer review. If the paper is co-authored, and most are nowadays, then the complexity in- creases yet again. Often in the protracted process of getting an article published, the ul- timate target of that paper—the reader—gets ignored. So this is your Editor’s plea for great writing and great graphs, along with great science. 4 JEM Editor-in-Chief’s Report Vol 13, No 3 Journal of Ecosystems and Management 13(3):4. Published by FORREX Forum for Research and Extention in Natural Resources. JOURNAL OF Ecosystems & http://jem.forrex.org/index.php/jem/article/view/567/482 Management Managing Editor’s Report Managing Editor’s Report Marilyn Bittman olume 13.3 of the Journal of Ecosystems and Management offers readers an eclectic collection of articles from invasive weed species to the information needs of silvi- Vculture practitioners and researchers, to the effects of tree spacing over time, to a literature review on the juglone, as well as the protection of ancient western redcedar stands. JEM also offers readers a collection of “News” articles: Tongli Wang looks at the distribution of ecosystem climate niches in British Columbia, Glen Okrainetz and Al Neal bring to our attention prescribed fire treatment, and finally, Suzan Lapp describes how teams were first brought together in Saskatchewan in a tournament to address drought issues. The tournament has become a popular event and has since been held in Alberta and British Columbia, with plans well underway for 2013. The first article is a research report by Don Gayton and Val Miller, “Impact of Biolog- ical Control on Two Knapweed Species in British Columbia.” The authors examine two types of knapweed species – diffuse and spotted – on numerous rangeland sites and how biological control has been used to successfully control this invasive species. They also offer explanations as to why certain biocontrol agents have been successful. Al Wiensczyk’s “2010 Silviculture Techniques Information Needs Survey” provides valuable information to BC natural resource management professionals on silvicultural systems and stand management techniques. The purpose of this FORREX generated elec- tronic survey was to help pinpoint the main knowledge gaps within silviculture. Survey respondents identified numerous knowledge gaps and also identified
