Out of a total of 1,200 leaves (from low-density plots), measurements of pigments and nitrogen (using the Dualex device), as well as traits such as specific leaf area (SLA), and observations of damage caused by herbivorous insects (see photo) were conducted. The goal is to assess the combined effect of water stress risk and herbivory (including chewers, sap feeders, gall makers, skeletonizers, and the presence of stink bugs) depending on the stand composition.<\/p>\n<p>This protocol\u2014excluding Dualex measurements\u2014is also being implemented in two other networks: ORPHEE (led by Herv\u00e9 Jactel) and GMAP (led by Xavier Morin), focusing on other oak-based mixtures. These measurements will be repeated over a period of four years. The individuals being monitored are marked with tape (see photo).<\/p>\n<p><a href=\"https:\/\/optmix.efno.fr\/wp-content\/uploads\/2025\/09\/20250716_125120_small.jpg\"><img decoding=\"async\" loading=\"lazy\" class=\"alignnone size-medium wp-image-3364\" src=\"https:\/\/optmix.efno.fr\/wp-content\/uploads\/2025\/09\/20250716_125120_small-300x142.jpg\" alt=\"\" width=\"300\" height=\"142\" srcset=\"https:\/\/optmix.efno.fr\/wp-content\/uploads\/2025\/09\/20250716_125120_small-300x142.jpg 300w, https:\/\/optmix.efno.fr\/wp-content\/uploads\/2025\/09\/20250716_125120_small-1024x485.jpg 1024w, https:\/\/optmix.efno.fr\/wp-content\/uploads\/2025\/09\/20250716_125120_small-768x364.jpg 768w, https:\/\/optmix.efno.fr\/wp-content\/uploads\/2025\/09\/20250716_125120_small-750x355.jpg 750w, https:\/\/optmix.efno.fr\/wp-content\/uploads\/2025\/09\/20250716_125120_small.jpg 1266w\" sizes=\"(max-width: 300px) 100vw, 300px\" \/><\/a><\/p>\n<p><a href=\"https:\/\/optmix.efno.fr\/wp-content\/uploads\/2025\/09\/20250915_165915_small.jpg\"><img decoding=\"async\" loading=\"lazy\" class=\"alignnone size-medium wp-image-3363\" src=\"https:\/\/optmix.efno.fr\/wp-content\/uploads\/2025\/09\/20250915_165915_small-142x300.jpg\" alt=\"\" width=\"142\" height=\"300\" srcset=\"https:\/\/optmix.efno.fr\/wp-content\/uploads\/2025\/09\/20250915_165915_small-142x300.jpg 142w, https:\/\/optmix.efno.fr\/wp-content\/uploads\/2025\/09\/20250915_165915_small-485x1024.jpg 485w, https:\/\/optmix.efno.fr\/wp-content\/uploads\/2025\/09\/20250915_165915_small.jpg 600w\" sizes=\"(max-width: 142px) 100vw, 142px\" \/><\/a><\/p>\n","protected":false},"excerpt":{"rendered":"<p>As part of the PEPR FORESTT X-Risks project, oak leaf samples were collected from resprouts in early September.
