Prescribed fire is a globally relevant fuel treatment for surface fuel management and wildfire hazard reduction. However, Mediterranean ecosystems are adapted to low and moderate fires; hence, the useful life of prescribed fires is limited. Useful life is defined as the effective rotation length of prescribed fires to mitigate fire spread based on critical surface intensity for crown combustion. In this sense, the useful life of a prescribed fire focuses on surface fuel dynamics and its potential fire behavior. In Pinus pinaster stands, the useful life can be established between 0 and 4 years. Canopy base height, time elapsed from the burning, postfire precipitation, and fine fuel moisture content during the burning were identified as the most important variables in postburn fuel dynamics. Other stand characteristics and postfire precipitation can improve the fine fuel and live fuel dynamics models. Our findings support prescribed fires as an effective fuel treatment in the medium term for forest fire prevention, according to stand characteristics and burning implementation conditions. In this sense, forest managers can use the proposed decision tree to identify the useful life of each prescribed fire based on fine fuel moisture content during burning implementation.

The percentage of victimization of Dutch Jewry during the Shoah is the highest of Western, Central and Southern Europe (except, perhaps of Greece), and close to the Polish one: 75%, more than 104.000 souls. The question of disproportion between the apparent favorable status of the Jews in society – they had acquired emancipation in 1796 - and the disastrous outcome of the Nazi occupation as compared to other countries in general and Western European in particular has haunted Dutch historiography of the Shoah. Who should be blamed for that outcome: the perpetrators, i.e. the Germans, the bystanders, i.e. the Dutch or the victims, i.e. the Dutch Jews? The article first surveys the answers given to this question since the beginnings of Dutch Holocaust historiography in the immediate post-war period until the debates of today and the factors that influenced the shaping of some basic perceptions on “Dutch society and the Jews”. It then proceeds to detailing several facts from the Holocaust period that are essential for an evaluation of gentile attitudes. The article concludes with the observation that – in spite of ongoing debates – the overall picture which has accumulated after decades of research will not essentially being altered. Although the Holocaust was initiated, planned and carried out from Berlin, and although a considerable number of Dutchmen helped and hid Jews and the majority definitely despised the Germans, considerable parts of Dutch society contributed to the disastrous outcome of the Jewish lot in the Netherlands – through a high amount of servility towards the German authorities, through indifference when Jewish fellow-citizens were persecuted, through economically benefiting from the persecution and from the disappearance of Jewish neighbors, and through actual collaboration (stemming from a variety of reasons). Consequently, the picture of the Holocaust in the Netherlands is multi-dimensional, but altogether puzzling and not favorable.
