Abstract:The Lower Siret Meadow forest habitats have been altered from natural structure because of commercial forestry operations, activities that are defining the forest management from previous decades. Afforestation programs aimed to test the introduction of exotic tree species in order to increase wood production and to reduce harvest time intervals. These commercial influences reflect in the decrease of natural forest areas, aspect that could influence the birds presence. Studies on the ecological impact of plantations on birds are scarce, and no studies were found regarding this aspect in the region. Using six different sample areas both in native and non-native tree plantations, we investigated how bird presence is influenced by the support capacity offered by both natural or non-native plantations and which vegetation variables are related to our results. We compared the data from the surveyed areas to relate birds presence and dependence on certain characteristics of the habitats. Our results pointed out that species diversity is higher in natural forests with local tree species and vegetation characteristics like forest canopy density, shrub coverage, and herbaceous layer.
The ecosystems from the Special Protection Area ROSPA0071 „Lower Siret Meadow” (36492 ha, between Adjud city, Vrancea County and Şendreni village, Galaţi County) in the analysed sector (sixteen sample surfaces) present a scientific interest because of the geographical, ecological and biological characteristics. The paper treats details such as the number of individuals, the spatial distribution, availability of suitable habitats and threats, necessary data for the evaluation of the conservation status. We present the data obtained in the period 2010–2014 from 64 field visits in the Special Protection Area ROSPA0071 „Lower Siret Meadow”, all made in the hiemal season. The observations were made as an activity of monitoring the protected bird species distribution and habitat selection of wintering populations. Five important sites were identified as being used by wintering birds here. During the monitoring actions, eighty–one bird species were identified. The paper brings new data about the way birds use their range and existing habitats for wintering.
