Charcoal production in Portugal is mostly based on the valorization of woody residues from cork oak and holm oak, the latter being considered a reference feedstock in the market. Nevertheless, since wildfire prevention became a priority in Portugal, after the recent dramatic wildfires, urgent actions are being conducted to reduce the fuel load in the forests, which is increasing the amount of biomass that is available for valorization. Additionally, biomass residues from agriculture, forest management, control of invasive species, partially burnt wood from post-fire recovery actions, and waste wood from storm devastated forests need also to be considered within the national biomass valorization policies. This has motivated the present work on whether the carbonization process can be used to valorize alternative woody biomasses not currently used on a large scale. For this purpose, slow pyrolysis experiments were carried out with ten types of wood, using a fixed bed reactor allowing the controlled heating of large fuel particles at 0.1 to 5 °C/min and final temperatures within 300–450 °C. Apart from an evaluation of the mass balance of the process, emphasis was given to the properties of the resulting charcoals considering its major market in Portugal—barbecue charcoal for both recreational and professional purposes.

On sinking the cellars for a large house at the upper part of Church-street in this town, now building by Daniel Wilson, esq. on the site of which stood some very old houses (formerly called the Judge's lodgings), was discovered, at about six feet below the present surface of the street, a supposed Roman burying-place; as burnt wood, bones, and ashes, broken paterae, urns, Roman brick, gutter tiles, coins, horns of animals, &c. were found; also, two fragments of thick walls, at about five yards distant from each other, in a direction from front to back, and seeming to continue under Church-street, be-twixt which were several large stones, some of which were hewn. By this it may be conjectured, to have been a vault to deposit the ashes of the dead, and fallen-in, or pulled down, at some time, as there were found, within the walls, several pieces of urns, an earthen sepulchral lamp entire (the end of the spout where the wick came out was burnt black), broken paterae, burnt bones, ashes, a large human skull, Roman coins, &c. also, at the North-end a well, filled with hewn stones, but not meddled with.

Disregarded for centuries, Mediterranean pine forests in Spain have been severely affected by human activities including fires and livestock grazing. As a consequence, reforestation programs were started by the late 1800s, albeit the origin of the seeds was not considered until the late 1960s. In July 2005, a large Pinus pinaster Ait. forest, located in Guadalajara (central Spain), burned down. In this area, we studied fire-related fitness traits in natural stands (zone N) and compared them to those of trees sown with seeds from foreign sources (zone S). Cone production per hectare in zone N doubled that found in zone S. In addition, zone N resulted in more saplings per hectare as well as more small trees bearing cones than zone S. In zone S, trees showed thicker crowns and less fructification resulting in open formations with low intraspecific competition. Whereas in the natural stands the average percentage of serotiny per tree was 32%, in the sown stands only one serotinous cone was found in seven unburned harvested trees. Compared with zone S, the presence of seedlings after springtime was almost nine times higher in zone N in spite of the damaging effects of logging and removal of burnt wood.

Artificial food patches were used to examine whether red bellied-pademelons (Thylogale billiardierii) and Bennett’s wallabies (Macropus rufogriseus rufogriseus) altered their foraging behaviour in an open habitat (a young plantation) in response to distance from cover, used as a surrogate for predation risk. Analyses using the full dataset showed no significant relationship between the amount of food eaten at a station and any of the cover variables. In contrast, regression analyses of the upper bounds dataset indicated that both increased distance from windrow (2.5-m-high stacks of burnt wood) and from nearest cover (windrow or forest at plantation edge) significantly reduced the amount of food consumed at a station. This indicates that distance from cover acts as a constraint on the amount of food eaten. When the feeding-station data were overlayed onto a map of scat densities across the study site, the amount of food eaten was positively related to the density of scats of both red-bellied pademelons and Bennett’s wallabies. Our results demonstrate that these macropods trade-off increased foraging benefits in order to forage closer to protective cover. Furthermore, they represent the first time that artificial food patches, with progressively decreasing reward per search effort, have been used to assess foraging behaviour in macropods. This opens up a wide range of research opportunities aimed at examining macropod foraging, with both ecological and practical applications.
