Three Eurasian Pygmy-Owl broods were discovered in the Jura Mountains, at relatively close distances from each other at 425 and 470 meters respectively. Nesting took place at an average altitude of 1200 meters, in Spruce Picea abies with a diameter of about 50 centimeters. Two of them were woodpecker cavities in dead trees, while the third was a natural cavity in a healthy tree. The breeding season of 2021 was favoured by an abundance of forest-dwelling small mammals, which led to a high breeding success and to early laying dates. [ABSTRACT FROM AUTHOR]

This study aims to assess the current state of health of the cork oak (Quercus suber) and its evolution in the forest of Zouagha (Mila). For this, eight plots were chosen at random. The dendrometric parameters measured are the diameter at 1.3 m above the ground and the total height of the trees, thus morphological observations were made on the aerial part of the same samples and analyzed by the tree architecture method (ARCHI). The average density of cork oak in this forest is 157±24 individual/ha with an average basal area of 27.09 ± 8.53 m²/ha. The diagnostic results show that the majority of trees in these plots are currently in classes of the ARCHI R type with a rate of 51.1%; comes in second position the ARCHI Healthy type with a percentage of 39.2; and the ARCHI S type records a low rate (7.3%). The ARCHI D and ARCHI I types are almost absent. The sanitary condition of these plots is quite good, despite the negligible presence of standing dead trees. [ABSTRACT FROM AUTHOR]
