Understory species typical of the native Pyrenean oak forests in the Iberian Peninsula contribute to maintaining high understory richness in such mixed pine forests. Context: The influence of stands characteristics on the understory in mixtures that combine coniferous tree species of the same genus deserves more study since they are frequent in Spain. Aims: To assess the effect of mixed versus monospecific stands of Pinus sylvestris L. and Pinus pinaster Ait. on the main tree species regeneration and understory species composition. Methods: Tree regeneration and understory species composition were inventoried in eighteen forest plots (6 triplets) in North-Central Spain. Each triplet consisted of two plots dominated either by Scots pine or Maritime pine and one mixed plot that contained both species. Results: The basal area (%) of both Pinus species was the only characteristic of the stands that significantly influenced the understory composition and tree regeneration. Characteristic species of humid and temperate zones, including P. sylvestris regeneration, dominated in Scots pine stands, and typical species of well-drained Mediterranean areas, including P. pinaster regeneration, dominated in Maritime pine stands. In mixed stands, the highest regeneration of the native Pyrenean oak with respect to monospecific stands was accompanied by understory species typical of native oak forests that share the same regeneration niche. Conclusion: Mixed pine forests allow the development of understory species better than monospecific forests.

Distribution patterns of forest species along an Atlantic-Mediterranean environmental gradient: an approach from forest inventory data / A. Olthoff in Forestry, an international journal of forest research, vol 89 n° 1 (January 2016)

Simultaneously, we would like to identify the relative contribution of spatial and environmental variation to the species compositional patterns. Spatially structured environmental and fine-scale spatial variables explained more tree compositional distribution than broad-scale spatial variables, suggesting that niche partitioning is the main process influencing forest species abundances along this gradient. However, vegetation compositional changes were mainly determined by the north–south topographic-climatic differences (primary coenocline), although steepness was also related to the particular location of some plant communities. Unimodal response curves dominate along the gradients, with tree species optima at different points, providing evidence of a sufficient amount of compositional turnover. Niche location of trait-related tree species is closely located. Tree species occupying environments with sharp contrast or transitional environments have broadest niches, whereas those species occupying localized habitats showed the narrowest niches. The methodology used provides an objective assessment of the shape of species' responses along complex ecological gradients, as well as of the spatial and environmental factors implicated in their distribution patterns using datasets from national forest inventories. The description of the main factors determining the gradients and the species distributions and niche characteristics will improve our ability to discuss potential conservation management goals or threats due to land uses changes and future climate change.
