The pine processionary moth (Thaumetopoea pityocampa) is a lepidopter species of significant social and forestry interest, with its distribution potentially expanding in recent decades. However, the climatic and ecological drivers behind its expansion remain unclear. Cambium Group undertakes research to investigate the causes and patterns of pine p...

La procesionaria del pino es el insecto defoliador más abundante en los pinares mediterráneos. Esta especie es muy sensible al aumento de las temperaturas porque desarrolla su fase larvaria durante los meses de inverno. La procesionaria podría estar expandiéndose en latitud y altitud, mientras que las poblaciones más meridionales podrían reducirse...

The integral role of wild fungi in ecosystems, including provisioning, regulating, cultural, and supporting services, is well recognized. However, quantifying and predicting wild mushroom yields is challenging due to spatial and temporal variability. In Mediterranean forests, climate-change-induced droughts further impact mushroom production. Funga...

In the Mediterranean region, inner rural and mountain areas suffered abandonment and land marginalization. Extensive conifer afforestations were established in these areas, which are particularly vulnerable to climate change and its associated risks. To identify critical areas where climate change could negatively impact forest vitality, we need to...

Pine species are a key social and economic component in Mediterranean ecosystems, where insect defoliations can have far-reaching consequences.

Impacts of climate warming on forests vigour are forecasted to increase in magnitude. Yet it remains unclear how stand characteristics and competition modulate the relationship between tree growth and gross primary production with drought. Here, we studied how the spatial variation in stand density, basal area and height modulates tree growth (Basa...

Remote sensing is increasingly used in forest inventories. However, its application to assess genetic variation in forest trees is still rare, particularly in conifers.

Urban tree inventories usually involve the collection of field data on the location, genus, species, crown sh...

The installation of research or permanent plots is a very common task in growth and forest yield research. At young ages, tree height is the most commonly measured variable, so the location of individuals is necessary when repeated measures are taken and if spatial analysis is required. Identifying the coordinates of individual trees and re-measuri...

The diameter distributions of trees in 50 temporary sample plots (TSPs) established in Pinus halepensis Mill. stands were recovered from LiDAR metrics by using six probability density functions (PDFs): the Weibull (2P and 3P), Johnson's SB, beta, generalized beta and gamma-2P functions. The parameters were recovered from the first and the second mo...

Controlling vegetation fuels around human settlements is a crucial strategy for reducing fire severity in forests, buildings and infrastructure, as well as protecting human lives. Each country has its own regulations in this respect, but they all have in common that by reducing fuel load, we in turn reduce the intensity and severity of the fire. Th...

Mushrooms play a provisioning ecosystem service as wild food. The abundance of this resource shows high annual and interannual variability, particularly in Mediterranean ecosystems. Climate conditions have been considered the main factor promoting mushroom production variability, but several evidences suggest that forest composition, age and growth...

Soria is a forested province in Northern Spain. The utilization level of the forests in Soria is low at present, but it is predicted to rise in the future. Because of the high altitude, heating is also needed. These form a good basis for increasing the use of wood chips in energy production. In this study, a procedure to estimate the potential of w...

Whole-stand models normally require data on initial stand basal area and dominant height. Dominant height measurements are time-consuming and often imprecise, compromising subsequent predictions. Poplar plantations provide a special case where basal area correlates with site index; a whole-stand model could thus be based on stand basal area. We rep...
