Mangroves are ecologically important ecosystems and globally protected. The purpose of this study was to evaluate the effectiveness of mangrove conservation efforts in two adjacent protected areas in China that were under the management policies of the Ramsar Convention (Mai Po Marshes Nature Reserve (MPMNR), Hong Kong) and China's National Nature Reserve System (Futian Mangrove National Nature Reserve (FMNNR), Shenzhen). To achieve this goal, eleven Landsat images were chosen and classified, areal extent and landscape metrics were then calculated. The results showed that: from 1973-2015, the areal extent of mangroves in both reserves increased, but the net change for the MPMNR (281.43 hm 2 ) was much higher than those of the FMNNR (101.97 hm 2 ). In general, the area-weighted centroid of the mangroves in FMNNR moved seaward by approximately 120 m, whereas in the MPMNR, the centroid moved seaward even farther (410 m). Although both reserves saw increased integrality and connectivity of the mangrove patches, the patches in the MPMNR always had higher integrality than those in the FMNNR. We concluded that the mangroves in the MPMNR were more effectively protected than those in the FMNNR. This study may provide assistance to the formulation of generally accepted criteria for remote sensing-based evaluation of conservation effectiveness, and may facilitate the development of appropriate mangrove forest conservation and management strategies in other counties.

“…General circulation models predict temperature increases of 3.11-3.67 °C and precipitation increases of 2-14% over the southern Great Lakes region (Illinois, Indiana and Ohio) (Ehman et al, 2002), whereas for northern Wisconsin, even larger temperature changes (up to 5.8 °C) are projected (Scheller & Mladenoff, 2005). Global climate change is expected to affect the growth, distribution and species composition of forests at several spatial and temporal scales (Graham et 2002) examined the possible responses of tree species to a twofold CO 2 -changed climate scenario, and found an overall decrease in total basal area for northern conifers and northern deciduous species.…”

“…Table 9 shows how population centroids of different species groups are expected to shift under baseline as well as changed climate conditions by 2060. Ehman et al (2002) also predicted how population centroids of regionally dominant species will shift after 80 years (Table 10). Hufnagel According to the simulations, a significant change will be the loss of northern conifers and northern deciduous species from the study region.…”

Abstract. After giving an overview of climate change induced vegetation shifts in the Palearctic region in our previous paper, in this article we review literature available in Web of Science on North and South America. We study different geographical regions such as Canada, Alaska, California, Southwestern, Eastern and Southeastern USA, the Great Lakes region, the Great Plains, intermontane basins and plateaus, Rocky Mountains and the Cascades as well as Central and South America. We summarize main results of relevant field studies, experiments and model simulations. Predicted environmental changes include temperature increases, altering precipitation patterns, droughts, permafrost thaw and ground subsidence in arctic regions, enhanced El Niño Southern Oscillation, sea level rise, increasing salinity of the vadose zone, snowpack declines and various disturbances. All vegetation types are affected by these changes, to the most important phenomena belong e.g. reduction of arctic and alpine communities, decreasing area of taiga, shrub encroachment in tundra areas, northward expansion of the tree line, reduction in wetland areas, invasion, altering forest regeneration patterns, decrease in dominance of conifer species, increased cover of salt-tolerant plant species in tidal marshes, expansion of grassland, compositional and structural changes of grasslands and forests, drying up of bogs, landward migration of mangroves, savannification of forests, expansion of chaparral as well as upward migration of species in the mountains.

“…Recently, the benefits of carbon sequestration by forests have been highlighted and carbon sequestration has been measured throughout the world: in the United States (Sakata 2005;Calish et al 1978;Foley et al 2009;Ehman et al 2002;Im et al 2007), Europe (Backèus et al 2005;Liski et al 2001;Matala et al 2009;Pohjola and Valsta 2007;Sivrikaya et al 2007;Kaipainen et al 2004;Seidl et al 2007), Canada (Hennigar et al 2008;Thompson et al 2009), Oceania (Campbell and Jennings 2004) and Asia (Ravendranath 1995;Han and Youn 2009). Forests not only have economic value through the production of commercial timber, but they also have other values to society including acting as carbon sinks, supporting biodiversity, and providing water protection (Pukkala 2002).…”
