Peterson and Bruce McCune, Oregon State University, Corvallis.</p> <p class="AbstractText">Biodiversity patterns of young, managed stands is of concern to forest managers. Quick and convenient methods for assessing lichen biodiversity in stands is becoming a necessity. We assessed the diversity of epiphytic macrolichen communities with large plots (1 acre) in second growth stands without thinning, second growth with thinning, old-growth control stands, and nearby diversity hot spots in the Oregon Coast Range. Preliminary analysis of 36 stands has shown that alectorioid lichens are generally indicators of old growth, cyanolichens are generally indicators of hardwood trees or shrubs (Lobaria oregana acts more like the alectorioids), and a few parmelioid lichens are indicators of various conditions. Indicators were determined by two-way indicator species analysis, discriminant analysis, and a new method by Dufrene and Legendre. A summary and critique of the methods will be given.</p> <p class="AbstractMeeting">Presented at the 1996 meeting of the <a href="http://www.vetmed.wsu.edu/org_NWS/NWSci_Home.htm">Northwest Science Association</a></p> <br /> <font size="-1"><a href="http://www.landscapeecology.com">HOME</a> : <a href="http://www.landscapeecology.com/Info/">Info</a></font> <br /> <br /> </td> </tr> </table> <hr width="97%" /> <font="-1"><a href="http://www.landscapeecology.com">LandscapeEcology.com</a> - contact the webmaster, Eric Peterson, <a href="http://non-parametric.com/contact.php?return=http://www.landscapeecology.com">here</a>. </body> </html>
