“…Post-hoc tests showed little evidence for genus diversity effects at a plot level; genus diversity was only important for two metrics (crown surface area and crown depth) for two species; Q. faginea and P. nigra. Our results for both pine species are in agreement with other studies which found the same species to be primarily sensitive to total competition over mixing effects (Condés et al, 2020). The consistent negative effects of congenerics on Q. faginea highlight that, for this species, competition is most intense among neighbourhoods containing the same genus, in agreement with findings at the species level (Kunstler et al, 2016) and suggesting resource partitioning (Gómez-Aparicio et al, 2011;Tilman, 1982;Uriarte et al, 2004).…”

“…Also, it seems that there will be a trend towards a longer dry season in the Mediterranean. One way to mitigate its effects is by reducing density through thinning in maritime pine stands and/or with mixed stands [39,40] of maritime pine with other conifer or broadleaved species (Section 3.1).…”

Maritime pine (Pinus pinaster Aiton) is a forest tree species with a high representation in southwestern European countries, in particular Portugal, Spain, and France. The species traits and their flexibility and plasticity are of importance both for timber and to the sustainability of the forest systems. Extensive research has been made on the maritime pine systems and productions. The aim of this study is to review the state-of-the art on the knowledge of the species, their forest systems, and their productions, to identify vulnerabilities and to summarize tools to help its management. The specific objectives of this review are: i) characterizing maritime pine, its distribution, genetic material and provenances, the biotic and abiotic disturbances, the diversity and sustainability of its forest systems; (ii) its management, encompassing the silvicultural systems and practices; (iii) to list existing growth models, simulators and decision support systems; and (iv) present information on wood technology, including sylvotechnology, wood properties, and their use.

“…However, for instance resistance and relative resilience to drought in mixed stands might depend on depending on species identity, functional diversity in the mixture, site conditions and the developmental stage of the stands [43]. At the same time, in some recent studies, climate variables such as mean annual temperature and precipitation have been found to have a significant effect on tree allometry [44,45]. Hence, H-D models usually designed to be climate-independent will fail to evaluate future scenarios linked to climate change.…”

Estimating tree height is essential for modelling and managing both pure and mixed forest stands. Although height–diameter (H–D) relationships have been traditionally fitted for pure stands, attention must be paid when analyzing this relationship behavior in stands composed of more than one species. The present context of global change makes also necessary to analyze how this relationship is influenced by climate conditions. This study tends to cope these gaps, by fitting new H–D models for 13 different Mediterranean species in mixed forest stands under different mixing proportions along an aridity gradient in Spain. Using Spanish National Forest Inventory data, a total of 14 height–diameter equations were initially fitted in order to select the best base models for each pair species-mixture. Then, the best models were expanded including species proportion by area (mi) and the De Martonne Aridity Index (M). A general trend was found for coniferous species, with taller trees for the same diameter size in pure than in mixed stands, being this trend inverse for broadleaved species. Regarding aridity influence on H–D relationships, humid conditions seem to beneficiate tree height for almost all the analyzed species and species mixtures. These results may have a relevant importance for Mediterranean coppice stands, suggesting that introducing conifers in broadleaves forests could enhance height for coppice species. However, this practice only should be carried out in places with a low probability of drought. Models presented in our study can be used to predict height both in different pure and mixed forests at different spatio-temporal scales to take better sustainable management decisions under future climate change scenarios.
