Carbon flux and nutrients cycle (Isy-BIOC project): end of the sampling twigs campaign

Scots pine twigs were collected from May 31 to June 10, 2021 on OPTMix plots. These samples correspond to the end of the campaign carried out in 2020 as part of the Isy-BIOC project wich aimed at studying carbon fluxes and nutrient cycling in the forest ecosystem

Monitoring forest regeneration on OPTMix plots: a new protocol to estimate annual increments

As part of Juliette Brunaud’s Master 2 internship, a new protocol for monitoring the regeneration of sessile oak and Scots pine was developed. The objective of this new protocol was to estimate diameter and height annual increments for individuals between 30 and 60 cm in height. The first campaign was carried out in spring 2021.

Dead wood inventory in the experimental plots (ISY-BIOC project)

As part of the ISY-BIOC project and Marine Fernandez’s post-doctorate, a dead wood inventory was carried out in the experimental plots in spring 2021. The objectives of this inventory were: – to quantify the dead wood on the forest ground; – to calculate the wood biomass on the ground and therefore the corresponding carbon stock. …
