<sup>[[:bug_reporting|Report a bug, broken link, or incorrect content]]</sup>[[http://methods.landscapetoolbox.org|{{ field_methods:methodsguide3.png?220x120|}}]] ====== Vegetation Structure - Cover Pole Method ====== [[http://www.landscapetoolbox.org/about/get_involved|{{:abstract_in_dev.gif|}}]]\\ written by Karen Colson and Jason Karl ===== Method Type ===== Vegetation Structure/Obstruction - Quantitative ===== Other Names ===== None known, but names of structure/obstruction methods are not standard. ===== Description and Uses ===== The Cover Pole Method is used to evaluate vertical cover and vegetation structure. Instead of a cover board, it uses a 1.5m high pole marked every 10cm in alternating colors. The number of segments of the pole that are obstructed by vegetation when viewed from a specified distance away are recorded and converted to vertical cover measurements. ===== Advantages and Limitations ===== ===== Similar Approaches ===== Other vertical structure/obstruction methods include the [[Cover Board Method]], Line-point Intercept with Height, and the [[Visual Obstruction Method]]. ===== Manuals/Instructions ===== *[[http://jornada.nmsu.edu/sites/jornada.nmsu.edu/files/Volume_II.pdf|Monitoring Manual for Grasslands, Shrublands, and Savanna Ecosystems (Herrick et al. 2009)]]. === Video Instructions/Demonstration === <flashplayer width=600 Height=400>file=http://jornada.nmsu.edu/files/Videos/CovPole/CoverPole.flv</flashplayer> \\ <sub>**Video from the [[http://jornada.nmsu.edu|USDA-ARS Jornada Experimental Range]]**</sub> \\ \\ **Alternate method for the cover pole method** \\ <flashplayer width=600 Height=400>file=http://jornada.nmsu.edu/sites/jornada.nmsu.edu/files/Videos/AltCover/AlternateCoverPole.flv</flashplayer> \\ <sub>**Video from the [[http://jornada.nmsu.edu|USDA-ARS Jornada Experimental Range]]**</sub> ===== Technical and Application References ===== ===== Data Forms ===== === Printable data forms for the cover pole method can be downloaded from === * [[http://jornada.nmsu.edu/sites/jornada.nmsu.edu/files/veg_structure_dataform.pdf|Jornada Experimental Range Monitoring and Assessment Site]] === Electronic data forms can be found at the following sites === * Vegetation Structure data using the cover pole method can be recorded directly into the [[databases:Rangeland Database]] in the field. * An Excel version of the cover pole method data form that automatically calculates cover percentages can be found at the [[http://jornada.nmsu.edu/sites/jornada.nmsu.edu/files/Vegetation_Structure_automated_calc.xls|Jornada Experimental Range Monitoring and Assessment Site]]. * An version of the cover pole Excel form that is compatible with electronic PDAs can also be downloaded from the [[http://jornada.nmsu.edu/sites/jornada.nmsu.edu/files/Vegetation_Structure_automated_calc_unprot.xls|Jornada Experimental Range Monitoring and Assessment Site]]. ===== Web Search Results ===== <html> <script src="http://www.google.com/jsapi"></script> <script language="Javascript" type="text/javascript">//<![CDATA[ google.load('search', '1.0'); function OnLoad() { var searchString = '"vegetation structure cover pole"'; // create a tabbed mode search control var searchControl = new google.search.SearchControl(); options = new google.search.SearcherOptions(); options.setExpandMode(google.search.SearchControl.EXPAND_MODE_OPEN); options.setRoot(document.getElementById("web_results")); searchControl.addSearcher(new google.search.WebSearch(), options); var drawOptions = new google.search.DrawOptions(); options2 = new google.search.SearcherOptions(); options2.setExpandMode(google.search.SearchControl.EXPAND_MODE_OPEN); searchControl.addSearcher(new google.search.BookSearch(), options2); searchControl.draw(document.getElementById("book_results"), drawOptions); // execute searches searchControl.execute(searchString); } google.setOnLoadCallback(OnLoad, true); //]]> </script> <table border="0"> <tr><td width="50%"> <div class="search-control" id="book_results">Loading...</div> </td> <td width="50%"> <div class="search-control" id="web_results">Loading...</div> </td> </tr> </table> </html> ===== Discussion/Comments ===== <sub>**You must have an account and be logged in to post or reply to the discussion topics below.
