In den 1970er Jahren wurden dann auch zunehmend die Sekundärstandorte auf Feuchtwiesen aufgegeben, so dass derzeit fast 90 % der Bruten auf Ackerflächen (Tertiärstandort) stattfinden.
günstigeren Bedingungen) RL D Rote Liste Deutschlands (Bauer et al. Because of the clear interactions between bird abundance, type of field crop, and vegetation height and coverage, it follows that both habitat suitability assessments of arable fields and the definition of favorable vegetation structures for farmland birds should be crop species‐specific. Regionen in Höhen von mehr als 150 m ü. NN sind mittlerweile fast vollständig vom Kiebitz geräumt worden. The clarification of distribution and sizes of possibly surviving populations are crucial to inaugurate conservation measures. Three databases are used: abundance data of a typical farmland bird (Eurasian skylark), Corine land cover, and statistical land-use data from the German Agricultural Structure Survey. Urbanization is a global phenomenon that is encroaching on natural habitats and decreasing biodiversity, although it is creating new habitats for some species. We developed an empirical method to relate crop growth and farmland bird abundance, applicable on the landscape scale. We present a critical, quantitative review of 98 mainly peer-reviewed papers selected from 801 studies in temperate climate zones published over the period 1990–2017. Breeding population of Common Sandpiper Actitis hypoleucos remained at a rather similar low level (The globally threatened Aquatic Warbler Acrocephalus paludicola is an umbrella species for fen mires and is at risk of extinction in its westernmost breeding population due to severe habitat loss. Models were validated using data from similar Aquatic Warbler habitats in Lithuania. To support evidence-based conservation strategies, we have analyzed habitat preferences, breeding success, and population development in selected study sites within the Westerwald mountain range, representing a major stronghold of Whinchats in Germany. But detailed knowledge of demography is lacking for many species, especially in the tropics.

Radolfzell) wurden zwischen Ende Juni und Ende August 2015 vier Begehungen des Geländes durchgeführt. woodcock Scolopax rusticola). A 'read' is counted each time someone views a publication summary (such as the title, abstract, and list of authors), clicks on a figure, or views or downloads the full-text.

In Bavaria, sedentary Greylag geese (Anser anser) are monitored during the winter by two different citizen-based monitoring schemes: the International Waterbird Census [IWC] and hunting bag statistics. Durch die Wahl eines einheitlichen Stichtages für die heranzuziehenden Daten (31.12.2014) ist gesichert, dass auch bei später fertiggestellten Teilen der Betrachtungszeitraum identisch sein wird. als Lebensraum.

When combining the SDMs, models of urban bird species richness can be derived. There is an extensive literature on counting birds, but no consensus on the most appropriate units in which to record the results. 12.000 Paare umfasst. Here we examine fluctuations in populations during the non-breeding season (autumn to spring) of seven waterbird species, which co-occur on 122 neighbouring water bodies in south-west Germany. We quantified differences in the species richness and abundance of selected flora and fauna groups. The abundance of most species was positively related to temperature, especially in winter. droppings, moulted feathers or footprints) is frequently confused with those of other bird species, too.

We measured these two parameters in the study area, dominated by winter wheat, winter rapeseed, maize, and fallow fields, and adapted the moving window approach to a new method of “moving window growth” to describe the dynamic development of height and coverage of the crops over time. Here, we quantify the potential impact of an increase in maize fields on the diversity of farmland birds by means of high resolution (25 × 25 m) land-use scenarios. Ces conclusions ont été confirmées par les agences environnementales des différents états fédéraux allemands concernés par la conservation de cette sous-espèce de Gelinotte.The increasing use of biomass for energy production is reshaping landscapes into energy landscapes. Our study shows that the strength of population parameters and environmental forces can be decomposed into monthly and yearly effects. ent, delimitation of protected areas and efficiency of conservation measures. Hierbei ist die Landwirtschaft gefordert, sich verstärkt am Gelegeschutz zu beteiligen und Produktionsweisen zu entwickeln, die auch bei intensiver Landbewirtschaftung eine erfolgreiche Kükenaufzucht bei Feldvögeln ermöglichen.

As a consequence, the biodiversity associated with open woodland is declining. Based on an extensive literature review, supposed distribution and population estimates are described for T. b. rhenana in Germany. We conclude that even in recently established sites, canopy opening in connection with grazing is a very effective tool in nature conservation, especially in order to promote species that favour open, structurally diverse forest habitats.Zur Rettung des Westlichen Haselhuhns versammelte sich am 2.12.17-3.12.17 eine Gruppe von 35 Fachleuten in Sachen Ha-selhuhnschutz, Züchter von Arten der Hühnervögel, in Projektplanung erfahrene Artenschützer und Ver-treter der Naturschutzbehörden am PFALZMUSEUM FÜR NATURKUNDE in Bad Dürkheim.
