Data from: Release and establishment of the weevil Mecinus janthiniformis for biological control of Dalmatian toadflax in southern California
<p>We monitored populations of the stem weevil, <em>Mecinus janthiniformis</em>, the invasive alien weed Dalmatian toadflax (<em>Linaria dalmatica</em>) and other vegetation to document the impact of using <em>M. janthiniformis</em> as a biological control agent of <em>L. dalmatica</em>. Weevils were released in 2008 and again in 2014 after a wild fire. The results document increases and spread of weevil populations, decrease in Dalmatian toadflax and changes in cover of some vegetation classes. </p><div><br>Resources in this dataset:</div><br><ul><li><p>Resource Title: Consolidated data dictionary.</p> <p>File Name: consolidated_HV_meta.csv</p><p>Resource Description: Description of variables in Condensed_HV data file</p><p>Resource Software Recommended: Microsoft Excel,url: <a href="http://www.microsoft.com">http://www.microsoft.com</a> </p></li><br><li><p>Resource Title: Consolidated data.</p> <p>File Name: consolidated_HV.csv</p><p>Resource Description: Condensed data for each site by year for plant size, weevil density, vegetation cover and meteorological data, 2008-2019.</p><p>Resource Software Recommended: Microsoft Excel,url: <a href="http://www.microsoft.com">http://www.microsoft.com</a> </p></li><br><li><p>Resource Title: Cover_2008 data dictionary.</p> <p>File Name: cover_2008_HV_meta.csv</p><p>Resource Description: description of variables in the file cover_2008_HV</p><p>Resource Software Recommended: Microsoft Excel,url: <a href="http://www.microsoft.com">http://www.microsoft.com</a> </p></li><br><li><p>Resource Title: vegetation cover 2008.</p> <p>File Name: cover_2008_HV.csv</p><p>Resource Description: vegetation cover 2008-2011</p><p>Resource Software Recommended: Microsoft Excel,url: <a href="http://www.microsoft.com">http://www.microsoft.com</a> </p></li><br><li><p>Resource Title: vegetation cover 2013 data dictionary.</p> <p>File Name: cover_2013_HV_meta.csv</p><p>Resource Description: description of variables in the file cover_2013_HV, which contains vegetation cover 2013-2019</p></li><br><li><p>Resource Title: vegetation cover 2013.</p> <p>File Name: cover_2013_HV.csv</p><p>Resource Description: vegetation cover 2013-2019</p><p>Resource Software Recommended: Microsoft Excel,url: <a href="http://www.microsoft.com">http://www.microsoft.com</a> </p></li><br><li><p>Resource Title: dissections 2009 data dictionary.</p> <p>File Name: dissections_2009_HV_meta.csv</p><p>Resource Description: Description of variables in the file dissections_2009_HV, containing dissections of toadflax stems 2009-2011</p><p>Resource Software Recommended: Microsoft Excel,url: <a href="http://www.microsoft.com">http://www.microsoft.com</a> </p></li><br><li><p>Resource Title: dissections 2009-2011.</p> <p>File Name: dissections_2009_HV.csv</p><p>Resource Description: Data from dissection of toadflax stems 2009-2011</p><p>Resource Software Recommended: Microsoft Excel,url: <a href="http://www.microsoft.com">http://www.microsoft.com</a> </p></li><br><li><p>Resource Title: dissections 2012 data dictionary.</p> <p>File Name: dissections_2012_HV_meta.csv</p><p>Resource Description: description of variables in the file dissections_2012_HV, containing data from dissections of toadflax stems 2012-2019</p></li><br><li><p>Resource Title: dissections 2012-2019.</p> <p>File Name: dissections_2012_HV.csv</p><p>Resource Description: data from dissection of toadflax stems 2012-2019</p><p>Resource Software Recommended: Microsoft Excel,url: <a href="http://www.microsoft.com">http://www.microsoft.com</a> </p></li><br><li><p>Resource Title: stem_counts data dictionary.</p> <p>File Name: stem_counts_HV_meta.csv</p><p>Resource Description: description of variables in the file stem_counts_HV, which contains data on number of toadflax stems in 25 x 50 cm quadrats, 2008-2013</p><p>Resource Software Recommended: Microsoft Excel,url: <a href="http://www.microsoft.com">http://www.microsoft.com</a> </p></li><br><li><p>Resource Title: stem_counts.</p> <p>File Name: stem_counts_HV.csv</p><p>Resource Description: Number of toadflax stems in 25 x 50 cm quadrats, 2008-2013</p><p>Resource Software Recommended: Microsoft Excel,url: <a href="http://www.microsoft.com">http://www.microsoft.com</a> </p></li><br><li><p>Resource Title: stem_height data dictionary.</p> <p>File Name: stem_height_HV_meta.csv</p><p>Resource Description: description of variables in the file stem_height_HV.csv, which contains data on height of live Linaria dalmatica stems, 2008-2019</p><p>Resource Software Recommended: Microsoft Excel,url: <a href="http://www.microsoft.com">http://www.microsoft.com</a> </p></li><br><li><p>Resource Title: stem_height.</p> <p>File Name: stem_height_HV.csv</p><p>Resource Description: height of live stems of Linaria dalmatica, 2008-2019</p><p>Resource Software Recommended: Microsoft Excel,url: <a href="http://www.microsoft.com">http://www.microsoft.com</a> </p></li></ul><p></p>
