Forest Ecosystems
Forest ecosystems are essential when dealing with climate change mitigation goals. Carbon stock of forest stand can hold substantial amounts of carbon as well products made from wood provide substitution effect, reducing reliance on fossil fuels. Silvicultural practices, such as drainage, have proven to be highly efficient of enhancing tree volume, aligning with climate change mitigation goals. As forest drainage disruption for rewetting of drained areas gains momentum with appealing goals such as enhancing biological diversity and restoring natural ecosystems, it becomes imperative to account for the consequential trade-offs. While these efforts hold promise for achieving ecological objectives, it is crucial to recognize that carbon sequestration dynamics within these areas may undergo significant alterations. Notably, the years required to offset carbon losses resulting from deadwood formation may no longer align with climate change mitigation targets, necessitating a comprehensive understanding of the interplay between drainage disruption, carbon dynamics, and climate goals. Aim of the study was to quantify carbon dynamics in tree carbon pool 15 years after drainage disruption. Our central research question revolves around understanding when newly established forest can offset carbon losses resulting from deadwood formation and decay in their predecessors. Our findings suggest that, on average, the new forest stand is poised to offset these losses in approximately 12-15 years. These insights are critical for forest management strategies aimed at maximizing carbon sequestration and mitigating climate change impacts.
