“…In the case of habitats that are dependent on management, especially under eutrophic conditions e.g. in floodplains, delayed land use is often unattractive to farmers because of a probable low-quality hay harvest late in the season (Corbett and Hudson 2010). As a consequence, farmers may abandon meadow management and habitat conditions for Corncrakes deteriorate.…”

“…Late cut areas or uncut refuges were also found to host increased densities and species richness of arthropods in the subsequent year (Schmidt et al 2008, Buri et al 2013). While refuge strips in eutrophic floodplains should be mown or grazed late in the season to maintain habitat conditions, uncut patches form an important spring habitat for Corncrakes at breeding sites where vegetation growth starts late (Corbett and Hudson 2010).…”

SummaryCorncrakes Crex crex mainly breed in grassland, where they are threatened by mowing. Conservation requires delayed mowing or modified mowing methods. In large fields, it has been suggested that leaving strips of uncut grass may reduce mortality, especially of unfledged chicks. We attended mowing operations (2012–2015) in the Lower Oder Valley National Park in north-eastern Germany, where 10-m refuge strips were introduced. We documented the escape behaviour of adults and chicks and their use of refuge strips by observations and radio-telemetry. Flightless chicks crossed significantly shorter distances of mown area (< 20 m) than adults. When mowing from the outside inwards, chicks were not able to successfully escape to the field edge at > 31 m, adults at > 60 m distance to the edge and returned to the unmown block. Twenty-three percent of adults, 30% of families and 49% of independent chicks survived in 10 m-wide strips until such strips were either mown or left as refuges. Whereas adults departed the strips the next day, independent chicks stayed for up to 22 days after mowing in 15–30 m wide refuges. We recommend refuge strips for breeding sites where more effective measures cannot be applied. Farmers face less additional effort and lower financial losses compared with delayed mowing. A width of 10 m should be considered as the absolute minimum, because most birds left the cover already > 10 m for the first time and only wider refuges served as temporary habitat for young.

“…Some species of butterflies were even observed to deposit their eggs in arable land, while grassland and uncultivated land were used for nectaring ( J. Loos, personal observation). Thus, uncropped arable land, and arable land with low inputs of artificial fertilizers and pesticides, in combination with field margins or ditches, seemed to provide resources similar to grasslands (Corbett and Hudson 2010, Budka and Osiejuk 2013, Josefsson et al 2013, Loos et al 2014b. These examples illustrate that it is not only the main land-cover types by themselves that drive Transylvania's high biodiversity, but also their spatial juxtaposition.…”

Traditional farming landscapes have evolved as tightly coupled socioecological systems that support high biodiversity. However, land-use change severely threatens the high biodiversity of these landscapes. Navigating nature conservation in such landscapes requires a thorough understanding of the key drivers underpinning biodiversity. Through empirical research on mammals, birds, butterflies, and plants in a traditional cultural landscape in Romania, we revealed seven hypothesized drivers facilitating biodiversity conservation. Similar proportions of three main land-use types support the landscape species pool, most likely through habitat connectivity and frequent spillover between land-use types. Landscape complementation and supplementation provide additional habitat for species outside their core habitats. Gradients of woody vegetation cover and gradients in land-cover heterogeneity provide mosaic landscapes with wide ranges of resources. Traditional land-use practices underpin landscape heterogeneity, traditional land-use elements such as wood pastures, and human-carnivore coexistence. Top-down predator control may limit herbivore populations. Lastly, cultural ties between humans and nature have a central influence on people's values and sustainable use of natural resources. Conservation approaches should aim to maintain or restore these socioecological drivers by targeting the heterogeneous character of the forest-farmland mosaic at large scales through ''broad and shallow'' conservation measures. These large-scale measures should be complemented with ''deep and narrow'' conservation measures addressing specific land-use types, threats, or species. In both cases, conservation measures should integrate the entire socioecological system, by recognizing and strengthening important links between people and the environment.

“…Although the fundamentals of Corncrakeʼs ecology were laid down long time ago (reviewed by Schäffer & Koffijberg 2004, Koffijberg & Schäffer 2006, several interesting findings have emerged in the last decade. A study in Scotland documented that Corncrakes were attracted in highest numbers by so-called cover areas that were specifically managed to provide vegetation tall enough throughout the breeding season (Corbett & Hudson 2010). Fewer Corncrakes could be found in silage and hay fields and none in long-term set-a sides without any management.…”

Szép 2016. Preserving an obscure bird: achievements and future challenges of Corncrake (Crex crex Linnaeus, 1758) conservation in Hungary. -Ornis Hungarica 24(2): 1-17.Abstract The Corncrake is a strictly protected species in Hungary and a qualifying species of many natura 2000 sites. Despite its Least concern global conservation status, it receives much attention and was elected as "Bird of the Year" by MME BirdLife Hungary in 2016. In this paper, we estimate its population trends and analyse the suitability of the protected area system and agri-environment schemes for the species. We compiled information on major threatening factors and conservation measures applied for the species. We reviewed international publications on the ecology and conservation management of the species to extract information for practical conservation. We estimated that 500-2000 pairs of Corncrakes breed in Hungary. Although their breeding sites are well covered by protected areas, natura 2000 sites (42%) and High Nature Value Areas (67%), their population has declined by 55% over the last 20 years. We found that most of the major threatening factors are addressed by conservation management, and appropriate measures are applied in most cases. Recent research findings and recommendations by the BirdLife International Corncrake Conservation Team suggest that mowing of grasslands around nesting places should be delayed until 1-15 August either in the entire field or at least on 2 hectares around nests. Prescriptions of agri-environment schemes should also be adjusted to the above requirements and more farmers should be encouraged to enrol in Corncrake conservation programmes. We strongly suggest that more emphasis should be devoted to combat important threats for the most important breeding sites such as aridification and flooding.Összefoglalás A haris fokozottan védett faj, és jelölőfaja számos natura 2000 területnek Magyarországon. Annak ellenére, hogy globálisan nem veszélyeztetett, hazánkban mégis jelentős figyelmet kap, és a Magyar Madártani és Természetvédelmi Egyesület programjában is elnyerte a 2016-os "év madara" címet. Jelen tanulmányban megbecsültük jelenlegi állománynagyságát, és elemeztük annak változásait, valamint vizsgáltuk, hogy mennyire megfelelő a védett és natura 2000 területek, valamint a Magas Természeti Értékű Területek (MTÉT) elhelyezkedése a haris számára. Összegyűjtöttük a faj számára legjelentősebb veszélyeztető tényezőket, és az érdekében alkalmazott természetvédelmi intézkedéseket. Felkutattuk a nemzetközi szakirodalmat, és kigyűjtöttük azokat az ökológiai és természetvédelmi biológiai információkat, melyek segíthetik a faj gyakorlati védelmét. Eredményeink szerint hazánkban 500-2000 pár haris költ évente. Bár a védett, natura 2000 (42%) és MTÉT (67%) területek nagy arányban fedik le a haris költőhelyeit, állománya mégis 55%-kal csökkent az elmúlt 20 év során. A természetvédelmi intéz-kedések reagálnak a faj legfőbb veszélyeztető tényezőire, és az alkalmazott kezelések többsége is megfelelő. A legfrissebb kuta...
