Modeling fire size of wildfires

The extent of fires, their periodicity and their impact on terrestrial communities is always a concern. Wildfires play an important role in shaping landscapes and as a source of CO2 and particulate matter. Modeling the spatial variability of wildfire extent is an important subject in order to understand and to predict future trends on their effect in landscape changes.

Spraying forests does not get anything

Insect pests are a major threat to many forests worldwide, from boreal to tropical forest ecosystems. Some pests exhibit periodical outbreaks, after which their populations often crash as a result of natural biological control. In this study, authors assessed the performance of aerial spraying of insecticides on pine woodland stands to control pine processionary moth Thaumetopoea pityocampa (PPM) outbreaks in southern Spain.

Protected areas in the world’s ecoregions: How well connected are they?

Protected areas (PAs) are the main instrument for biodiversity conservation, which has triggered the development of numerous indicators and assessments on their coverage, performance and efficiency. The connectivity of the PA networks at a global scale has however been much less explored; previous studies have either focused on particular regions of the world or have only considered some types of PAs.

Almond shell vs. Wood pellet

Since many years, there were tries to value a subproduct of almond industry, which constitutes 75% of total almond biomass volume. Crashed and filtered almond shells, that we talk in this post about, surprisingly have similar characteristics to wood pellets. However, the biggest advantage of this energy carrier is undoubtedly its price, which is much more attractive, than its derived from wood competitor.

Low prices for wood

The European Sawlog Price Index reached its lowest level in six years in the 3Q/16 because of lower lumber demand and reduced prices in both domestic and export markets, reports the Wood Resource Quarterly Declining demand and prices for softwood lumber, together with reduced log trade have resulted in lower sawlog prices in Europe over the past two years with the ESPI sawlog prices index reaching its lowest point since 2010, according to the Wood Resource Quarterly.

Evolution for Forest Engineering in Spain

Forest engineering in Spain has a long tradition and active presence in the engineering field. It is also one of the first educational institutions that shaped the Spanish technological panorama in the mid nineteenth century. The actual situation of the forest systems in Spain is the result of 166 years of observation, research, education and the application of specific techniques and principles that forest engineers acquired with the successive study plans that were implanted in educational institutions.
