Over time, studies of the vegetation of natural grasslands have evolved from simple observations to rigorous research. Feed obtained from natural meadows without major technological imputations is mediocre in quality, and pastures in a rather advanced state of degradation. The main purpose of this paper is the ecological and fodder evaluation of the Festuca rubra type of grasslands in the Apuseni Mountains based on the floristic composition and the productivity of these grasslands. The experience was carried out in Ghetari village, Apuseni Mountains, which was located in 2001, following the method of randomized blocks with 4 experimental variants in 4 rehearsals. Each variant were fertilized with organic inputs using the same quantities each year. In the paper we use the results obtained after 15 years of experience. The application of organic fertilizers caused significant changes in the canopy causing changes in the dominance of the type of grassland. The livestock manure applied on the studied grassland has increases significant yield production at all variants of fertilization.In this paper it was shown on which species the productivity of the grassland increased from the control variant to the fertilized variant with the maximum dose. Regarding the analysis of the phytodiversity, this tells us if the number of species is reduced in all the treatments, 10 t/ha of manure leads to an increase in phytocoenosis equivalence and implicitly to the Shannon index.

Organic fertilizers have an influence on the floristic composition of grasslands. Fertilizing with manure favours the phytodiversity of grasslands. The objective of the study was to follow the influence of mulching and organic fertilizing in small quantities and at various time intervals upon dry matter yield and phytodiversity of Agrostis capillaris L. - Festuca rubra L. grassland type in the Apuseni Mountains. Seven treatments  ( control  ( mowed 1/year ) ; mulch 1/year; mulch 1/year + 5 t/ha manure /year; mulch 1/year + 5 t/ha manure/2 years; mulch 1/year + 10 t/ha manure/2 years; mulch 1/year + 10 t/ha manure/3 years; abandonment )  were evaluated experimentally. Organic fertilizing in low quantities could be a way to maintain the floristic diversity of oligotrophic grasslands in Apuseni Mountains.

Yield and quality of forage mainly depend on the floristic composition, ie the share of higher quality grasses and legumes, soil fertility, amount and distribution of precipitation and light. Natural meadows and pastures are the most important resource in the forage production in the hilly and mountainous area of Republic of Serbia. Despite the large areas, the forage production on natural grasslands is relatively low. Limited application of a small number of agrotechnical measures is the main reason for low and unstable yields and poor forage quality. Only by appropriate fertilization of meadows and pastures with mineral and organic fertilizers, their rational exploitation, it is possible to achieve an increase in hay yield by several times and improvement in forage quality, simultaneously.

Researchers current concerns are to maintain the high floristic biodiversity, enabling sustainable development of natural grasslands in mountain areas. Large surfaces of the Apuseni Mountains are fertilized with organic fertilization (these is the only way of fertilization used by grasslands owners), fact which causes probably the high phytodiversity specific for these area. Grassland management is the one who creates and maintains a high phytodiversity, being able also to reduce it drastically in a short time. This involves research at various levels of intensification in order to determine how productivity and phytodiversity of grassland evolves over time. The first studies conducted in the Apuseni Mountains were aimed to increase production and fodder quality through various technological methods (fertilization with organic fertilizers, amendment, overseeding etc.), without taking into account the specific biodiversity of phytocenosis. Currently the problem is changing radically and in all research actions undertaken is not overlooked the environmental dimension. Through this experience we plan to examine how different doses of organic fertilizers influencing productivity and fitodiversitatea of mountain meadows.

The organic fertilizers’ application and the traditional use for long periods of time have influenced the rich plant diversity in Apuseni Mountains, Romania. The objective of this study was to identify the effect of manure’s application upon the plant diversity and productivity of Festuca rubra L. –Agrostis capillaris L. grasslands. The experimental field evaluated four variants (V1: control, V2: 10 t ha-1 manure, V3: 20 t ha-1 manure, V4: 30 t ha-1 manure). After ten years, important changes at the sward level were observed. The control’s phytocenosis is naturally represented by Festuca rubra L. - Agrostis capillaris L. grassland type. Then, following the application of organic fertilizers, Trisetum flavescens L. - Agrostis capillaris L. appeared. The large quantities of organic fertilizers produced a considerable limitation on plant diversity. The applied treatments do not produce any important improvement of the grassland types’ agronomic value. Taking account the influence of organic fertilizers upon the DM yield, plant diversity and agronomic value, it is considered that the treatment with 10 t ha -1 manure annually applied produces optimum changes and might be taken into consideration for the low-input systems in Apuseni Mountains

Abstract. Wadi Yalamlam is known as one of the significant wadis in the west of Saudi Arabia. It is a very important water source for the western region of the country. Thus, it supplies the holy places in Mecca and the surrounding areas with drinking water. The floristic composition of Wadi Yalamlam has not been comprehensively studied. For that reason, this work aimed to assess the wadi vegetation cover, life-form presence, chorotype, diversity, and community structure using temporal remote sensing data. Temporal datasets spanning 4 years were acquired from the Landsat 8 sensor in 2013 as an early acquisition and in 2017 as a late acquisition to estimate normalized difference vegetation index (NDVI) changes. The wadi was divided into seven stands. Stands 7, 1, and 3 were the richest with the highest Shannon index values of 2.98, 2.69, and 2.64, respectively. On the other hand, stand 6 has the least plant biodiversity with a Shannon index of 1.8. The study also revealed the presence of 48 different plant species belonging to 24 families. Fabaceae (17 %) and Poaceae (13 %) were the main families that form most of the vegetation in the study area, while many families were represented by only 2 % of the vegetation of the wadi. NDVI analysis showed that the wadi suffers from various types of degradation of the vegetation cover along with the wadi main stream.

The maintenance of semi-natural grasslands within the mountainous landscape is deeply influenced by fertilization. Application of fertilizer will cause changes in the chemical composition of the plant and will increase the palatability, decreasing the denials. One should apply fertilizers taking into account the way of exploitation of the grassland. If the grasslands are grazed, much of the nutrients return into the meadow by manure, fattening being more important than on mowed lawns where all the nutrients taken from plants are exported. The aim of this paper was to assess the influence of organic and mineral fertilizers upon semi-natural grassland’s plant diversity on different soil types. The research was carried out in Apuseni Mountains, in an experimental field with one experience with organic fertilizers  ( T1 control, T2 10 t ha-1manure, T3 20 t ha-1 manure, T4 30 t ha-1 manure ) . Mineral fertilizers complex NPK 20:10:10 ratio was applied in three quantities: 50N 25P 25 K, 100N 50P 50K, and 150N 75P 75 K. The results showed that the largest quantities of mineral fertilizers generated a considerable decrease of plant diversity. For future management actions that are meant to maintain plant diversity in Apuseni Mountains, the organic fertilization with 10 t ha-1 manure quantities administrated annually or once on two years. In conclusion is justified to make organic treatments on Preluvosol Rodic soil type and mineral treatments on Eutricambosol Rendzinic soil type.

An important part of efficient livestock production is ensuring the sufficient grass for hay and pasture. However, low soil nutrient levels often limit forage production. With good fertilizer management and soil fertility, the productivity of many hay and pasture fields can be greatly improved. Through good fertilizer management, the productivity of many hay and pasture fields can be significantly improved by Ross H. McKenzie (2005). The aim of this paper was the effect of fertilization with liquid fertilizer (UAN) the harvest of dry and floristic composition changing on natural grassland. The experiment whose results we present was placed in 2014 in the place in Baisoara Mountain village, Cluj County. Experience has been placed on the Festuca rubra and Agrostis capillaries - of grassland type. The natural grassland of Festuca rubra with Agrostis capillaries responded very well to mineral fertilizers with liquid fertilizer UAN. The floristic composition of natural grassland fertilized with liquid fertilizers based on nitrogen, it can be seen an increase the Gramineae families and an evidence downward trend from Fabaceae families.

<p>The Atlantic Forest, which has a vast epiphytic richness, is a priority area for preservation, listed as one of the five most important world hotspots. Vascular epiphyte richness, composition and community structure were studied in two fragments, one of the ombrophilous (29º43'42"S and 50º22'00"W) and the other of the seasonal (29º40'54"S and 51º06'56"W) forest, both belonging to the Atlantic Forest biome in the Sinos River basin, Rio Grande do Sul, Brazil. In each fragment, 40 trees, divided into four ecological zones, were analyzed. In each zone, the occurrence of the species was recorded, and the importance value of each species was calculated according to the frequency of phorophytes and intervals, and cover scores. The Shannon index was calculated for the two communities. In the fragment of the ombrophilous forest (F1), 30 epiphytic species were recorded, and in the seasonal forest (F2), 25. The highest importance value was found for <italic>Microgramma squamulosa</italic> (Kaulf.) de la Sota in both fragments. The diversity indexes for F1 (H'=2.72) and F2 (H'=2.55) were similar and reflected the subtropical location of the areas. The decrease in mean richness in both fragments in zone 3 (internal crown) to zone 4 (external crown) may be associated with time and space availability for epiphyte occupation and microclimate variations. Exclusive species were found in the areas, which suggest that a greater number of preserved fragments may result in a greater number of preserved epiphytic species in the Sinos River basin.</p>

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 mesotrophic and eutrophic species to become established in fertilized meadows. In Romania, meadows belonging to this category occupy an area of approximately 1,600,000 hectares and have relatively low production rates. The experiment was located at Pojorata, Suceava County (Romania), in two different natural grasslands that had different floristic compositions. Manure improved the growth of a number of species, especially in the "plants from other botanical families" category, because of the pool of seeds that it contains. Using a management system based on fertilization with small amounts of organic and mineral fertilizers can help preserve the biodiversity of these meadows. The results of this study, in an area considered representative for large parts of the mountainous areas of Romania, indicated that fertilization treatments were able to maintain a high species diversity.
