“…Also in the framework of nutrient conservation and recycling, the decay of dead wood may play an important, and for scarce (often base) elements, be essential for the ecosystem. The results by Dhiedt et al (2019) in the strict reserves of Sonian Forest and Wijnendale forest, confirm important and gradual release of chemical elements, especially basic cations like Calcium from the decaying wood to the forest soil.…”

Woord Vooraf'Allez, het is er dan toch nog van gekomen!' hoor ik sommigen zeggen. Inderdaad, dit proefschrift was een werk van (zeer) lange adem, 10 jaar om precies te zijn. Met horten en stoten ging het dan weer even vooruit, om daarna voor een half jaar of langer stil te liggen. Mijn ambitie was om het vóór mijn 50ste verjaardag af te werken, maar dat is net niet gelukt. Ik wil dan ook beginnen met mijn promotor Professor Kris Verheyen te bedanken, niet alleen voor zijn deskundige en motiverende coaching, maar in de eerste plaats voor zijn engelengeduld, zeker wanneer ik weer eens een deadline die ik mezelf had opgelegd, schromelijk had overschreden. Omgekeerd moest ik echter nooit lang wachten op feedback: binnen de kortste keren was het manuscript nagelezen, en voorzien van motiverende suggesties, correcties en commentaren die er altijd 'boenk' op waren. Een betere promotor had ik me dus niet kunnen inbeelden. Merci, Kris! Vervolgens wens ik ook het management van het INBO te bedanken, in het bijzonder onze administrateur-generaal Prof. Maurice Hoffmann, die mij de mogelijkheid heeft geboden om een deel van mijn werktijd aan dit doctoraat te spenderen. Iin het bijzonder de zes maanden 'sabbatical' waar ik kon van gebruik maken om het proefschrift af te werken waren welgekomen en eigenlijk onontbeerlijk. Tegelijk ook dank aan mijn huidige en vroegere teamleiders Gerald Louette en Geert Deblust, voor hun steun en aanmoedigingen. Geen doctoraat zonder data, geen data zonder veldwerk, geen veldwerk zonder veldwerkteam. Dank aan Peter Van de Kerckhove, Marc Esprit, Stefaan Goessens en Bart Christiaens; altijd secuur en volledig, zelfkritisch en gedreven. Dank voor de vele uren in de lentezon, maar ook in de ijzige vrieskou, of bakkend in de auto in de file. Jullie werk wordt ongelooflijk geapprecieerd. Ook het team dat de eerste opmetingen deed in Zoniën: Koen, Peter, Paul, Bart, Danny, Seppe, dank dat we jullie dataset mochten adopteren en valoriseren. Merci ook aan het INBO-labo voor de uitgevoerde bodemanalyses. 'Du point de vue scientifique le but primordial des réserves est de permettre l'étude de l'évolution des associations, cette grandiose evolution de nos forêts, quelles qu'en soient les modalités, constituerait une donnée fondamentale pour le biologiste comme pour le forestier. (…) Il serait grand temps d'entreprendre chez nous les études de biosociologie, études très longues qui exigent la coordination et la continuation des travaux de plusieurs générations de chercheurs. Or, seules les réserves intangibles peuvent assurer la realization d'un tel oeuvre. Dans ces sortes de parcelles d'expérience, des diverses disciplines biologiques pourraient collaborer à une mission de fierté et d'intérêt national.(…) Tôt ou tard, de telles études s'imposeront chez nous avec le progrès des scéances.

“…The pattern of stocks for large and medium elements in this study can be better predicted using a negative exponential model, which may be attributed to the fast turnover of material in the subtropical region [25]. However, the release migration process of trace elements from the stump-root systems is influenced by numerous factors, and small changes in any of these factors can significantly impact the release [25,40,[54][55][56][57][58][59][60]. Therefore, further research is needed to gain a deeper understanding of the pattern of trace element release.…”

Stump–root systems consist of aboveground stumps and underground coarse roots after timber harvesting. Stump–root systems are the primary source of coarse woody debris (CWD) in plantations, and they play a crucial role in the material cycle, energy flow, and biodiversity of Eucalyptus plantation ecosystems. However, there is limited knowledge about the changes in elemental stock within this CWD type during decomposition. To address this gap, we conducted a study on Eucalyptus urophylla × E. grandis stump–root systems at various times (0, 1, 2, 3, 4, 5, and 6 years) after clearcutting. Our aim was to investigate the stock changes in eight elements (K, Ca, Mg, S, Fe, Mn, Cu, and Zn) within the stumps and coarse roots over time and their decay levels, and we analyzed the relationship between elemental stocks and the physical, chemical, and structural components of stump–root systems. Our findings revealed the following: (1) The majority of each element’s stock within the stump–root system was found in the coarse roots. The elemental stocks in both stumps and coarse roots decreased as time passed after clearcutting and as decay progressed. (2) Notably, the elemental stocks in stumps and coarse roots were significantly higher than in other treatments during the initial 0–2 years after clearcutting and at decay classes I and II. In terms of elemental stocks, stumps from all clearcutting times or decay classes had the highest K stock, followed by Ca and Fe. Mg, Mn, and S stocks were lower than the first three, while Zn and Cu stocks were very low. The ordering of elemental stocks from high to low in the stump–root systems generally aligned with that of the coarse roots. (3) The residual rates of K, Mg, and Mn stocks in the stump–root systems fit the negative exponential model well. It took approximately 1 to 3.5 years for a 50% loss of the initial stocks of these elements and 5 to 10 years for a 95% loss. (4) The large amount of biomass in the stump–root system is the long-term nutrient reservoir of plantations, and any factor related to biomass loss affects the magnitude and duration of the nutrient reservoir, such as N, P, stoichiometric ratios, density, water-holding capacity, and hemicellulose. These findings contribute to a better understanding of the nutrient elemental dynamics and ecological functions of stump–root systems in Eucalyptus plantations.

“…The lack of ameliorating effects near hornbeam in hornbeam-pine mixtures (both for pH and BC) is surprising. Other factors that we did not account for may be at play at this small scale, including spatial variations in herbivory or woody debris (Bardgett and Wardle 2003;Ehrenfeld et al 2005;Dhiedt et al 2019).…”
