“…Measuring landscape diversity is useful not only for land use change evaluation, but also for the prediction of potential impact on the structure and function of alternative land uses. In the Mediterranean basin, diversity is proven to be intrinsically associated with landscape heterogeneity and man-induced land use changes [88][89][90].…”

Landscape Pattern Changes in Response to Transhumance Abandonment on Mountain Vermio (North Greece)

et al. 2015

Transhumance, the seasonal movement of herds between highlands and lowlands following precise, repeated routes, is a common practice in many Mediterranean regions. This livestock movement exploits natural vegetation in both winter and summer pastures. In Greece transhumant herders, drawn by relatively abundant vegetation, usually relocate to mountainous areas between April and October. Mount Vermio was an ideal summer pasture for the nomadic, ethnic group Sarakatsanoi of Thessaly, who used to own big herds. Socio-economic conditions of the 20th century led to the gradual decline of transhumance, resulting in reduction in grazing pressure and changes in vegetation dynamics. The purpose of this study was to monitor changes in landscape patterns in response to transhumance abandonment. Landscape metrics were employed to estimate land use/cover in two altitudinal zones. Results reveal that due to the abandonment of transhumance in the highlands landscape fragmentation increased. Meanwhile, in the lowlands, due to the uninterrupted presence of animals, landscape structure is more stable and diversified. Grasslands and agroforestry systems became smaller and more isolated. In OPEN ACCESSSustainability 2015, 7 15653 conclusion, the abandonment of transhumance led to the overall deterioration of the rural landscape in the highlands.

“…The majority of diversity studies have been characterized by a lack of replication in sampling communities, and by subjective placement of quadrats, most notably in the work of Whittaker (Naveh & Whittaker 1979) and those who have followed his methods (e.g., Rice & Westoby 1983a, 1983b. In such studies, the results may reflect the preconceptions of the authors.…”

Fifteen plant communities were sampled, each by five randomly-placed quadrats. Bryophyte and vascular plant species were recorded.There were considerable differences between communities in species diversity. These agree with some theories, and conflict with others.Types of community that are young, in evolutionary time, did not seem deficient in species.Human disturbance, and the consequent invasion of exotic species, had very little effect on species diversity, but this seemed to be because of a balance between opposing trends, difficult to relate to niche limitation. Correlation gave no evidence that exotic species displaced natives from a fixed number of niches.Within-community variance in species richness is significantly greater than that predicted from a null model, providing no evidence for the niche limitation theory.

“…Communities sensitively respond to the specific grazing pressure similarly to vintage effects (Aiken, 1990 (Sala, 1988), species composition Moog et al, 2002) and species diversity (Virágh and Bartha, 1996;Pykälä, 2003;Pykälä et al, 2005). Grazing manners are indicated in vegetation and types of grazing appear in production (Naveh and Whittaker, 1979;Milchunas et al, 1988).…”

(phone: +36-28-410-200; fax: +36-28-410-804) Abstract. Investigations were carried out in wet and dry pasture. Coenological recordings were taken in three zones. The first zone ("A") located 0-50 m near the stable, second zone ("B") located 50-150 m from the stable, while the third zone ("C") located farther than 150 m. We have carried out analyses of ecological and environmental factors and life form types. Based on our results for both dry and wet grasslands, quadrates of "A" zone were well isolated from the rest of the zones. Overgrazing, which involves considerable trampling, vanishes differences among vegetations, thereby promotes weed and disturbance tolerant rich vegetation. The lowest species number and diversity could be found here. Due to the nitrogen enrichment due to the constant presence of livestock, drier and less heat demanding habitat developed in the "A" zones, according to the environmental indicators. Because of the change in management, conservation and diversity values of "C" zone increased, however, according to nature protection values it underperformed compared to "B" zone. According to the sample area, wet grasslands from the sandy areas of Kiskunság, preserve nature protection values and grass composition better moving away from stables, due to less grazing pressure. Drier backgrounds tolerate stronger grazing pressure.
