Peterson, Oregon State University, Corvallis.</p> <p class="AbstractText">Caliciales (pin-lichens) are a group of crustose lichens in which most species require old-growth forest structures. For lack of information on Caliciales in the Pacific Northwest, 16 species were listed in the Northwest Forest Plan under survey strategy 4, "conduct general regional surveys." Given the experience required to accurately survey and identify Caliciales, it is likely that the surveys will actually be minimal. Keys appropriate for identifying species in most of North America are not yet available. We are still learning which species occur in North America and the PNW. Complicating this, many Caliciales are difficult to see in the field. Fortunately most species are found in certain identifiable substrate and habitat types. Most old-growth associated species grow on bark and wood where they will be sheltered from rain water. Some are specific to certain habitats on trunks and logs (e.g. <i>Chaenotheca furfuracea</i> is limited to very sheltered sites often found under the bole of a tree). Many members of the Mycocaliciaceae are not associated with old-growth, but are restricted to twigs of a narrow range of phorophytes. Understanding which substrates and habitats are used by various species of Caliciales greatly increases success with surveying species that occur in stands.</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>
