Istoria românilor, România însăşi, este o poveste ce continuă să fascineze cu trecutul său, să țină trează atenția cu prezentul și cu perspectivele viitorului. Preşedintele Academiei Române, istoricul Ioan Aurel Pop, este clujean, iar în Bucureşti locuieşte într-un apartament cochet – ce aduce aminte de perioada boierimii bune, la primul cat al Casei Oamenilor de Ştiinţă. O clădire tulburător de frumoasă, sprijinind la vest piaţa Lahovary, dar care azi are un aer uşor decrepit. La mansardă, e ca-n Nichita, când plouă e infernal. În 2001 – la 46 de ani, Ioan Aurel Pop devenea cel mai tânăr membru corespondent al Academiei Române din întreaga existenţă de 153 de ani a instituţiei, iar pe 5 aprilie 2019 urmează a sărbători un an de când conduce destinele celui mai înalt for ştiinţific şi cultural al României. Revista „Bucovina Forestieră” a beneficiat de un dialog cu preşedintele Ioan-Aurel Pop, nu doar din perspectiva împlinirii primului său an de mandat, ci mai ales din dorinţa de a afla părerea istoricului despre patimile trecute, prezente şi – probabil - viitoare ale pădurii românești.

Bucovina Forestieră journal continues to present, through the voice of some personalities who know the reality of Romania’s forests, moments of reference from their recent past, a prerequisite for working on better future of forests. Because it is part of our recent history, this issue will address the restitution subject - especially those carried out in the national forestry fund - which reality must be brought to light. The views belong to some personalities involved in the presentation of historical truth, especially in Transylvania, the place which, unfortunately, suffered the most due to restitutions process: the lawyer Ioan Sabau Pop and the historian Mihai-Dorin Drecin. Mr. Ioan Sabau Pop is Professor, Doctor in Law and Representative of Romania at the International Court of Commercial Arbitration. Mr. Mihai-Dorin Drecin is also a Professor, specialist in the modern history of Romania. Corresponding member of the Academy of Romanian Scientists, historian Mihai Drecin is like Mr. Ioan Sabău Pop, a Transylvanian personality who strives to stop the abuses and injustice caused by illegal restitutions.

The paper analyzes the effect of the bearing capacity of the foundation ground on the volume and cost of some dams. Using a theoretical model, were analyzed 125 dams, as resulted from the combination of five categories of useful heights, with five categories of loads in the spillway, and five foundation ground categories with known bearing capacity. In our simulation, we choosed often-used dams that have an upside-down foundation and are made of beton. When deciding the spill area, we took into account the most unfavorable load scheme and the safety factors imposed by norms and basic, plus special loads. In order to achieve an economical optimum, it is necessary to minimize the cost of each work, which, translates into a function that aims to minimize the volume of the dam, and also to minimize the area of its section. The external and internal stability conditions became mandatory criteria for the objective function. The 125 dams were dimensioned using a Microsoft Excel spreadsheet prepared accordingly, while the minimization of the section was done using the Solver tool. It has been pointed that the section area and, implicitly, the volume of a 1 m wide dam stripe increases, as the load capacity the foundation ground. These volumes increase with the useful height of the work and the task of the spillway. The obtained results show that the specific investment indicator (determined as the ratio between the cost of the proposed works and the consolidated area) is also influenced by the nature of the foundation ground, and its use for comparing projects located at different conditions, at least in the case of dams, is not recommended. | În lucrare se analizează influența capacității portante a terenului de fundare asupra volumului unor baraje. În cadrul unui model teoretic se analizează 125 de baraje rezultate prin combinarea a cinci categorii de înălțimi utile cu cinci categorii de sarcini in deversor și amplasate pe cinci categorii de terenuri de fundație la care se cunoaște capacitatea portantă S-a optat pentru barajele des utilizate în practică care au fundație evazată spre amonte și sunt executate din beton. La dimensionarea zonei deversate s-a luat în calcul schema de sarcini cea mai defavorabilă și coeficienții de siguranță impuși prin normative pentru clasa IV de importanță și sarcini de bază + speciale. Pentru realizarea unui optim economic este necesar să se minimizeze costul fiecărei lucrări ceea se transpune într-o funcție obiectiv care urmărește minimizarea volumului barajului implicit la minimizarea ariei secțiunii sale.  Condițiile de stabilitate exterioare și interioare au devenit în cadrul dimensionării criterii obligatorii la realizarea funcției obiectiv. Cele 125 baraje s-au dimensionat cu ajutorul unui tabel de calcul construit in utilitarul Microsoft Excel iar minimizarea secțiunii s-a realizat cu ajutorul instrumentului Solver  S-a demonstrat că aria secțiunii și implicit volumul unei fâșii de baraj cu lățime de 1 m crește pe măsură ce capacitatea portantă terenului de fundare. Aceste volume cresc odată cu înălţimea utilă a lucrării și sarcina deversorului. Rezultatele obținute demonstrează că indicatorul investiție specifică (determinat ca raport între costul lucrărilor propuse și lungimea consolidată)  este influențat și de natura terenului de fundare, iar utilizarea lui pentru compararea unor proiecte - amplasate în condiții diferite,  cel puțin în cazul barajelor, nu este recomandată.

The study on the craniometry of golden jackal (Canis aureus, Linnaeus 1758) is justified in the context of the latest rapid growth of this predator effectives in Romania. The growth is the effect of the return to the initial area, but the current demographic increase also leads to an expansion of the area. The study highlights the results of biometric measurements and analyzes of the variability of the craniometric characteristics of the golden jackal. The statistical investigations show a low variability of all the measured cranial features thus proving the homogeneity of the sample extracted from the population. Between most of the elements analyzed there are very significant correlations, indicating a symmetrical, well proportioned architecture of the skull. Furthermore, the comparison of the means of two sets of craniometric measurements, by sex, showed no significant statistical differences between the dimensional features of the golden jackal skulls from Southeastern Romania and those in Bulgaria. | În curând

The paper presents the problems related to the forestry domanin in the first decade after the Great Union. It contains an introductory part, including general considerations on the concepts of forest policy and law, and the main part, which is a study of forest policy based on the existing forest laws. The main conclusion of the paper is related to the involvment of foresters in contributing with their knowledge to shaping measures of forest policy, law and administration in the benefit of forests.

All countries, including Romania, are increasingly affected by biological invasions. As a result, the need to study this phenomenon has become increasingly apparent. The aim of the present paper is to report the presence of five new forest insect species recently found in the northeastern part of Romania and data on their distribution in the region. The detection of the insect presence was done using identification sheets based on their morphological aspect and the characteristics of the attack, following a protocol that would make investigating work more efficient. Of the alien species found, five are new to the area of Moldova and are discussed in the present paper. They are: Dasineura gleditchiae (Osten Sacken, 1866), Appendiseta robiniae (Gillette, 1907), Prociphilus fraxinifolii (Riley, 1879), Corythucha arcuata (Say, 1832) and Nematus (Pteronidea) tibialis Newman, 1837. The first three are also new species for Romania’s fauna. For each species, data are presented concerning the systematic classification and the host species, where and when it was found, the type of crop and the age of the infested trees, the frequency and severity of the attack, the region from which it originated, where it was reported for the first time in Europe and in the neighboring countries of Romania, and to what extent it is a potentially harmful pest. All species presented in the work come from North America and four of them have been found on host species from their native area (black locust, honey locust and green ash), while the fifth is mainly found on native species of the genus Quercus. Except for C. arcuata, all of them have been present in Romania, including the studied region, for at least a decade or even longer, but have gone unnoticed in the absence of research like those presented in this paper. Currently they are present almost everywhere where their host species are grown. Apart from N. tibialis, the insect species reported have the potential to become important pests of their hosts. As a result, it is necessary to study their biology and ecology in the ecosystems in which they entered in Romania.

This editorial tackles a very intriguing issue: should the foresters be involved in policy? Such a question really makes sense because in the last almost three decades, Romanian foresters have been complaining about forestry politicizing in the sense that forest resources and forestry staff have been used by ruling parties as electoral means, without any concern for forest sustainability. It has happened so because the forest policy must be contextualized in a broader perspective of conceiving and keeping consistent quite a long array of public policies, where the environmental protection public policy actually engulfs the forest policy. The argument that some professional groups shall keep away from making policy is logically dismantled by the fact that conceiving public policies implies a lot of technicalities that cannot be grasp without having a deeper understanding of what is going in different sectoral economies. Keeping some professionals, like physicians, foresters and militaries out of the political parties is not good at all for these domains (supposedly public policies) because all technical provisions will have been produced or amended by non-processionals. Especially the parties based on the neo-liberal doctrine shall be heavily packed with foresters for the simple reason that liberal politicians, in general, are prone to disregard the positive externalities produced by forests. In general, any political party shall have more technical lenses for domains where its own political doctrine tends to be sightless.

This year the national student conference in forestry took place between 25 and 26 of May and was hosted by Faculty of Silviculture and Forest Engineering from Transilvania University of Brașov. Thirty papers were presented by students, master and PhD students of profile faculties in the country: Faculty of Silviculture and Forest Engineering from Brașov, Forestry Faculty from Suceava, Faculty of Agriculture Bucharest, Faculty of Horticulture Cluj-Napoca and Faculty of Environmental Protection in Oradea. Entomology, silviculture, botany, wood study, forest harvesting, dendrometry and forest inventories, hunting, genetics, GIS were the main topics of presentations. Through this the the participants had the opportunity to share their knowledge and work, to learn new things and to crystallize their perspective on forestry and the environment.

The mission of writing an obituary for Professor Ioan Milescu (1928-2018) hides in itself a strong emotional, affective, moral charge and challenges anyone who would like to illustrate, in a cosmic fraction, what meant for us a Man whose Book of Life is full of lessons and models for every mortal. Under the unspoken but responsible oath, generated by personal trust by handing the evidence by which my illustrious master has become a remarkable personality, I intend to show that the virtues that defined the personality and life of Professor Ioan Milescu - honor, respect, professionalism, morality, style and elegance - have been cultivated for a long time, making it a symbol of our time. Endowed with the Grace of the Master, his reign has always conveyed the origin and qualities of a true high-profile intellectual: verticality, competence, ethics, openness to the new. The undeniable proof is that the theory of well-done work has perfectly applied it: it has published over 190 scientific papers, out of which 20 are textbooks, monographs and synthesis works, recognized for a solid scientific foundation, some of them being awarded with high academic distinctions.
