Abstract. Rached-Kanouni M, Hani I, Bousba R, Beldjazia A, Khammar H. 2020. Structural variability of Aleppo pine stands in two forests in northeastern Algeria. Biodiversitas 21: 2848-2853. The layout of the stand can be described as the width of the trees, their reciprocal locations, diametric distinction and height. The goal of this study is to recognize changes in the Pinus halepensis spatial and demographic systems in two Beni Oudjana and Chettaba Forests, located in northeast Algeria. An inventory of trees in these forest formations with P. halepensis dominance was carried out based on dendrometric parameters such as total height, tree diameter at dbh ≥ 5 cm, basal area, total volume, etc., as well as the number of trees in the forest. Tree diameter and height measurements were made on 12 rectangular plots (20 m × 20 m), located in both forests. The results obtained show that the mean stand density, mean diameter, basal area and total volume are higher in Chettaba Forest, the values attributed to these parameters are respectively (422 trees/ha, 27.07 cm, 26, 86 m2, 251.63 m3); while the total height and regeneration rate show significantly higher values in Beni Oudjana Forest (18.97 m, 607 individuals/ha). The structure in diameter and height of the species is bell-shaped to asymmetrically positive with a predominance of small diameter individuals in the Chettaba forest. On the other hand, in the Beni Oudjana Forest, the structure is ‘L’ shaped, showing a predominance of very small diameter individuals. These results indicate that the low regeneration rate of P. halepensis in the Chettaba Forest is due to anthropogenic pressures that favor the degradation of this forest.

In September 2017, 96 egg batches of Thaumetopoea pityocampa were collected from Aleppo pine (Pinus halepensis) trees at four sites of Thasos Island in Greece. In the different localities, the average number of eggs in batches varied from 196.5 to 223.9 (212.4 for the Thasos Island). The length of P. halepensis needles with egg batches differed in size - between 84 to 210 mm. Approximately 75% of batches were laid close to the middle of needles, between 121 and 180 mm. The egg masses were formed mainly on two needles (84.4%) and the rest - on one, three or four needles (13.6%) or on fine shoots (2%). In most cases (88.3%), the female moths started to lay eggs from the tip of the needle. The distance from the base of the needle to the beginning of the egg batches was established between 0 and 180 mm, as most of them (62.7%) were clustered around the average value (87.3 mm) in the diapason of 60-120 mm. The average rate of T. pityocampa survival in egg stage was 48%. The parasitized eggs were 43.8%, and the rest included unhatched eggs, predominately undeveloped eggs with dried-up yolk. No correlation was found between the percentage of parasitized eggs and the distance of the egg batches from the base of needles.

Natural Stand

Two prescribed burnings (downhill and uphill fires) were conducted in two stands of Aleppo pine (Pinus halepensis Mill.): a natural stand and a managed stand that was subject to thinning, pruning, and shrub removal. The concentrations of nitrogen (N) and phosphorus (P) in the pine needles and regrowth of the main shrub species, Quercus coccifera L., and the quantities of N and P in the needle fall and in the forest floor were measured during the 6 months following the fires. The concentrations of N and P in the pine needles and leaves of Q. coccifera increased compared with the unburned control after both fires in the natural stand, where there was only a slight reduction in fuel during prescribed burnings and where there was an abundant fall of scorched needles. In contrast, the chemical composition of the foliage was unchanged after the fires in the managed stand, where there was a greater reduction in fuel, and where only small quantities of scorched needles fell. This study showed that first opening prescribed burnings (natural stand) were less severe in terms of nutrient balance than maintenance prescribed burnings (managed stand) and that the forest floor reduction was a good indicator of fire severity.

Alepski bor (Pinus halepensis Mill.) se koristio u pošumljavanju krša šibenske regije od sredine 19. stoljeća, te se zbog toga ova vrsta često javlja u ranije zasnovanim parkovima. Upravo zbog poznatih dekorativnih karakteristika, te kulturološke vrijednosti, cilj rada je izvršiti inventarizaciju i predočiti estetsku ocjenu zelenih površina s alepskim borom. U tu svrhu provedena je taksonomska analiza vrsta na zelenim površinama s alepskim borom. Florističko i anketno istraživanje je provedeno tijekom 2013. godine na području grada Šibenika. S obzirom na tip habitusa po Erhardtu i sur., 2002. dominiraju grmolike forme i alohtone dendrološke svojte. Temeljem rezultata istraživanja vizualnog dojma „geštalta”, putem anketnog ispitivanja, zaključak je da ispitanici ugodno doživljavaju parkovne prostore s alepskim borom.

At the end of the 19th century and along the first half of the 20th century, public policies in Mediterranean countries and elsewhere in Europe strongly promoted pine afforestation for land reclamation and wood production. In many cases, the transition to native forests, more resilient and more diverse, was also foreseen. This study aims to find the overstory characteristics that are best related to the understory of Aleppo pine (Pinus halepensis) plantations, to assist ecosystem restoration goals. We installed 33 circular plots in mature Aleppo pine plantations located in the southeastern Salento peninsula, Apulia, Italy. We measured overstory characteristics and the corresponding understory on these plots. We assessed the effects of overstory variables on understory development (plant density, plant height, and the Magini regeneration index) and diversity (species richness and the Shannon–Wiener index) using linear mixed models (LMM). Understory development and diversity were positively correlated with the Hart–Becking spacing index and negatively correlated with basal area and canopy cover, the three overstory variables that best explained variance. We used polynomial fitting and the subsequent derivation of these functions to determine the values of the Hart–Becking index and of the canopy cover that corresponded to the maximum development (33.7% and 84.6%, respectively) and diversity (32.6% and 86.5%, respectively) of the understory. Redundancy analysis (RDA) showed that late-successional species, including Quercus coccifera, were associated with higher levels of understory development and stand spacing. These results may assist in the restoration of native ecosystems in Aleppo pine plantations installed in similar ecological conditions.
