Peterson and Bruce McCune. Oregon State University, Corvallis.</p> <p class="AbstractText">The Pacific Northwest forest plan requires surveys for 17 species of pin-lichens (Caliciales s.l.), but the experience required to accurately survey and identify pin-lichens complicates their inclusion in forest management decisions. For this reason, we are developing a method to model species occurrence at sites or in stands. Models of species occurrence are useful in many ways. Decisions on management options under modern forest plans often require models of species patterns across a landscape. Management of rare species often relies on similar models. Species surveys can be easier if a list of expected species is available. Our method models the occurrence of species in target stands according to climatic and stand characters. The model uses a database of stands with known environmental characters and species compositions. Species presence is modeled by the proportion of its occurrence in similar sites. Software in development can now be run to model species composition in individual forest stands and soon will use GIS layers to model species occurrence across a landscape. Although the modeling concept originated for pin-lichens, the concept and software should be broadly applicable to a variety of organisms.</p> <p class="AbstractMeeting">Presented at the 1999 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>
