AmeriFlux US-Mpj Mountainair Pinyon-Juniper Woodland

This is the AmeriFlux version of the carbon flux data for the site US-Mpj Mountainair Pinyon-Juniper Woodland. Site Description - This site is located in central New Mexico on an extensive mesa approximately 25 km south of Mountainair, NM, owned by the Heritage Land Conservancy. The dominant tree species, Pinus edulis and Juniperus monosperma make up >95% of the area’s tree cover.  Total tree is cover is ~60%. The dominant herbaceous plant at the site is the C4 perennial grass Bouteloua gracilis. In July 2013, we observed pinon mortality at the site, which continued through 2015. We have used a variety of techniques to document the rate of mortality. The mortality was triggered by a combination of drought (2011-2013) and Pinon ips bark beetle outbreak. Juniper was not affected.

本数据集为美国通量网（AmeriFlux）针对站点US-Mpj 迈泰尔矮松-杜松林地所发布的碳通量数据版本。站点概况——该站点位于新墨西哥州中部一处广袤台地，距新墨西哥州迈泰尔以南约25公里，土地归属遗产土地保护协会（Heritage Land Conservancy）。区域内优势树木为矮松（Pinus edulis）与单籽杜松（Juniperus monosperma），二者占该区域树木总覆盖面积的95%以上，整体树木覆盖率约为60%。站点优势草本植物为C4型多年生牧草格兰马草（Bouteloua gracilis）。2013年7月，研究团队在该站点观测到矮松死亡现象，该现象持续至2015年。团队采用多种技术手段记录树木死亡速率，此次死亡事件由2011-2013年的持续干旱以及矮松IPS小蠹虫（Pinon ips bark beetle）爆发共同引发，杜松未受此次事件影响。
