Grasslands, especially those under ecological management (i.e. mowing, and grazing without fertilizers and chemicals), have significant importance for many arthropods, including ground beetles. We studied the abundance and species diversity of Carabidae of four uphill grasslands (West Sudety Mountains, Poland) under different management intensity: cattle grazing (one or four times per year), mowing, and alternatively managed (grazing/mowing). Beetles were collected using pitfall traps during three whole grazing seasons, i.e. from April to October in 2007–2009. The most frequent species of beetles, on each of the plots, were predators Poecilus cupreus, Calathus fuscipes and Nebria brevicollis. Sixtyfour ground beetle species were found altogether. Species richness ranged from 42 to 47, with the mean number of individuals per trap day-1 from 0.006 to 0.018. In the years of the study the number of ground beetles and their species diversity were higher on meadows mown once per year and alternatively managed grasslands as compared with grazed sites. Therefore, the simplified, organic way of agricultural production with reduced mowing or moving combined with grazing can be considered as appropriate in preserving the biodiversity of the grasslands in mountainous regions.
Mangrove forests are one of the most productive and bio-diverse wetland environments on earth. Yet these unique coastal tropical forest environments are among the most threatened habitats in the world. Some key progress points in mangrove conservation, restoration, and research in Malaysia are highlighted. Based on an intensive literature review, the ecology and ecological management, distribution and areas of existing mangroves in the world and Malaysia, issues associated with mangrove conservation and restoration are discussed. Growing in the intertidal areas and estuary mouths between land and sea, mangroves provide critical habitat for diverse marine and terrestrial flora and fauna. Important for the flora and fauna is the opportunity to continue living in a sustainable environment and in suitable conditions. A potential stand is the place that obtains the possibility of germination and establishment of a plant species according to their physical, chemical, and biological demands. In many cases it is seen that because of unsuitable selection of site and species, afforestation and reforestation projects are forced to fail after spending time, cost, and labor. The population boom and rapid economic developments have greatly reduced mangrove areas in Malaysia despite the Malaysian government launching a series of programs to protect mangroves in the 1980s and establishing mangrove ecosystems as high-priority areas for improving environmental and living resource management. The issues, threats, and significant values of mangroves also were highlighted. A more systematic protection strategy using ecological engineering management-based, active restoration and rehabilitation measurements still are urgently needed in order to preserve these valuable resources in Malaysia.
