In the context of increasing grassland abandonment we observed wild herbivore impact on the vegetation in order to understand their influence. To quantify semi-natural grassland usage by wild herbivores, we determined grazing intake in semi-natural hay-meadows surrounded by forest vegetation. Grazing exclusion cages were placed at three locations in the Valea Mare village area situated in Bistriţa-Năsăud County, Romania, from 1 April 2014 – 5 October 2014. Sampling took place at two times during this period, first shortly before the hay meadows were mowed and second at the end of the vegetatio

Seminatural meadows are characterized by a rich botanical composition, which determines their specific type. The content of macro- and micro minerals in sward seems important for ruminant farmers. The aim of the study was to determine the content of macro- and micro minerals in the sward of selected meadow types. The study was carried out in SE Poland from May to July in the years 2010–2017. The relationship between the content of each of the studied elements (N, P, K, Mg, Fe, Mn, Cu, Zn) in soil and plants was investigated, as well as whether there were differences between the average content

This investigation examines the influence of fertilization with organic and mineral fertilizers on the biodiversity of grasslands containing Festuca rubra, Agrostis capillaris and Nardus stricta. Permanent meadows were studied in terms of production of food, and of biodiversity. The current strategy of using organic fertilizers has raised concerns about resource conservation and environmental protection. The increase in the number of species is due to the fertilizers that have been applied leading to changes in the soil fertility status. This change in soil fertility has allowed other mesotrop

Churra Tensina is a coarse-wooled hardy breed usually managed in semi-extensive systems in Spanish Pyrenees. Grazing natural meadows in spring together with lambing season could be involved in the alternatives of its production system. The aim of this experiment was to study the effect of dietary supplementation of lambs on grazing behaviour of Churra Tensina ewes and their lambs during lactation in natural meadows.

Semi-natural grasslands have been severely affected by agricultural land-use change. However, the isostatic land adjustment following deglaciation in the Northern Hemisphere means that new land is continually being created in coastal areas. We modelled isostatic adjustment during the last 4000 years in a region of the Baltic coast to estimate the emergence of potential grassland habitat. We also compared the α and β diversity of existing managed and abandoned coastal meadows, and assessed their contribution to biodiversity at landscape scales. We estimated that half the 7866 km 2 of emerging l

SUMMARYSemi-natural hay meadows are among the most biodiversity-rich terrestrial ecosystems, and are managed for conservation purposes in most of Europe, including Sweden. Romania has some of Europe's largest areas of grasslands still managed with traditional methods. Through interviews and field studies, current management practices were investigated in two Romanian villages, and compared with CAP-generated grassland management in Swedish hay meadows and historical Swedish management of grasslands. The study evaluated the effect of the eligibility criteria within both countries’ National Rura

Abstract The area of traditionally managed semi-natural meadows is declining throughout Europe. Knowledge of how to restore their species richness is urgently needed. Community manipulations by means of grazing and mowing and, on the other hand, knowledge of species-level responses as well as the responses of functional plant groups to management may help in planning appropriate restoration tools. The restoration of species richness was studied in two community-level experiments: in a sheep grazing experiment and in a mowing experiment. Three species-level studies were conducted to test the co

Die Kulturlandschaft und ihre Bewirtschaftung haben sich seit dem Beginn der großräumigen Intensivierungsprozesse (z.B. Meliorationen, synthetischer Düngung und Herbizidgebrauch) in den 1950/60er Jahren in Mitteleuropa dramatisch geändert. Viele der ehemaligen artenreichen Grünlandflächen wurden in den letzten Jahrzehnten beseitigt (z.B. durch Umbruch zu Acker). Dies führte zu einem allgemeinen Grünlandrückgang in Deutschland. Heute werden die meisten Ackerflächen und die restlichen Grünlandflächen sehr intensiv bewirtschaftet. Die gegenläufige Entwicklung, die Umwandlung von Äckern zu Grünlan

Vegetation inventory and mapping is a process to document the composition, distribution and abundance of vegetation types across the landscape. The National Park Service’s (NPS) Inventory and Monitoring (I&M) program has determined vegetation inventory and mapping to be an important resource for parks; it is one of 12 baseline inventories of natural resources to be completed for all 270 national parks within the NPS I&M program. The Mojave Desert Network Inventory & Monitoring (MOJN I&M) began its process of vegetation inventory in 2009 for four park units as follows: Lake Mead
