“…Openness in forest canopy might affect the number of invertebrates present in a forest stand. In studies of oak stands of central Europe, Horak et al, (2014) found a higher abundance and diversity of invertebrate taxa in open and semi-open habitats than in forests with higher degrees of canopy closure. On the other hand, Pereira et al, (2014) showed that insectivorous warblers were more abundant in dense oak stands with a more extensive cover of understory vegetation.…”

The Mediterranean basin exhibits a multitude of forest habitats affected by former and current exploitation and management. Recent afforestation programs have resulted in an increase in the proportion of coniferous trees, while oak stands, formerly utilized for coppicing and grazing, are abandoned or converted into coniferous plantations. The loss of oak stands might negatively affect birds dependent upon broadleaved forests. Studies confirming or rejecting that statement are scarce, particularly in the eastern part of the region. Using a study area in southwestern Turkey we applied a guild-based approach to investigate how pine and oak stands across a chronosequence differ in their capacity to support forest bird assemblages. Variables describing the vegetation were sampled to characterize the stands and relate bird assemblages to stand structure. Bird abundance and species richness was positively associated with age for both stand types. Richness and diversity was highest in oak stands, while there were no differences in bird abundance between the two forest types. Pine stands supported a different bird species composition compared to oak stands of the same age. Stand age and structure, rather than forest type, held the highest explanatory powers for bird assembly structure. Primary cavity-nesters and ground-nesters were more abundant in oak stands, possibly reflecting differences in stand structure and resource distribution. To support these birds with suitable habitats, oaks stands need conservation. Management practices in pine stands should strive for increasing the amount of old trees and retain vegetation in the understory to benefit breeding birds.

“…The positive effect that big oak trees have on biodiversity has previously been described on many sites (Ranius et al 2009;Lassauce et al 2012;Bouget et al 2014). Some studies consider sun-exposed dead branches more important for biodiversity of saproxylic beetles than the remaining dead branches (Vodka et al 2009;Horak et al 2014). However, all types of dead branches are more important for this group of organisms than live branches.…”

“…The crown shapes of the standards depend on their competitors, and their development and shape can be influenced by management targeting the competing tree species. Such management decisions affecting crown development may have implications for stand biodiversity, as certain groups of organisms associated with the presence of big veteran trees prefer different strata of the crowns (Horak et al 2014).…”

“…The presence of dead wood in crowns is also important, although to a lesser extent, for biodiversity of oak-feeding xylophagous beetles (Vodka et al 2009). At the same time, some studies stress that open forests, open landscape and semi-open woodland pastures enhance the biodiversity of organisms dependent on dead wood (Franc, Götmark 2008;Horak et al 2014). Due to the importance of oak for biodiversity, the other tree species forming standards have been neglected.…”

AbstractŠálek L., Machar I., Sivacioğlu A., Zahradník D., Simon J., Jeřábková L. (2017): Crowns of "forgotten" standards in hardwood floodplain forests. J. For. Sci., 63: 538-548.Floodplain forests have traditionally been managed using the coppice-with-standards silvicultural system for centuries. After abandoning this silvicultural system approximately in the 1950s the crown of standards (mature-aged trees) developed gradually under the growing influence of their tree competitors. This study examines the crowns of remnant oak and ash standards in a hardwood floodplain forest along the Morava River in the Czech Republic. 100 oak (Quercus robur Linnaeus) standards and 100 ash (Fraxinus excelsior Linnaeus) standards were randomly selected and the basic mensuration data as well as some ecological data, such as number of large dead branches, cavities, and height of the lowest large dead and green branches, were measured. The four nearest neighbour competitors were identified for each standard, and their height, distance and azimuth were measured. The DBH of the analysed oak standards ranged between 71 and 148 cm, and the projected oak crown area ranged between 125 and 533 m 2 . The ash DBH ranged between 71 and 127 cm, and projected ash crowns between 194 and 620 m 2 . To assess competitive pressure, we calculated an index as a ratio of the tangents of angles of regular and compressed crowns. Distance of competing trees was more important than their height in the ash data set, but not in the oak data set.

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.
