“…NDVI is a key vegetation cover index because it is tightly linked with successful ecological restoration (Li et al, 2006;Zhang et al, 2007;Wang et al, 2010Wang et al, , 2013Cao et al, 2011). Our results (Tables 1 and 2) demonstrate that degradation of the vegetation cover is caused by both natural and socioeconomic factors, which agrees with previous research (Olukoye and Kinyamario, 2009;Schwilch et al, 2009).…”

“…This is probably because the strategy has not been tailored to local environmental conditions, leading to the use of inappropriate species and an overemphasis on tree and shrub planting, thereby compromising the ability to achieve the goals of this restoration policy . This result has also been documented based on monitoring data from areas where afforestation has been practiced Wang et al, 2013;Qu et al, 2013).…”

“…To understand how these factors have affected vegetation cover, we analyzed specific driving factors that our literature review suggested would be primary factors responsible for vegetation cover change (Li et al, 2006;Cao et al, 2009Cao et al, , 2011Zhang et al, 2007;Wang et al, 2008Wang et al, , 2010Wang et al, , 2013Dai, 2010): the rural population, grain yield, rural net income, livestock population, area of farmland, area of forest in which agriculture and grazing were forbidden, reforestation area, mean annual temperature, total annual precipitation, and infrastructure (roads, railways, and mining). We hypothesized that these factors would differ in their effects on vegetation cover, that certain key factors would explain most of the overall effect, that the key factors and magnitude of their effects would differ among the regions of a country as large as China, and that identifying these differences would provide empirical evidence to support improved policy development.…”

Information on the ecological functions of forests is important for sustainable forest management. In this study, we introduced the national monitoring program which has been used in China to evaluate the overall health status and ecological functions of forests. We also compared it to similar monitoring programs operating in Europe and the United States of America. We revealed the strength and drawbacks of China's monitoring program by analyzing the initial evaluation results. Our analysis showed that among the three programs, the European program gives the most detailed measurements of conditions of forests while the U.S. program generates the most detailed information on individual trees. In comparison, China's monitoring program has a higher spatial resolution but is narrowly focused on trees and uses coarse classifications of indicators. The health status of forests in China suggested that more resources should be invested to improve the health of existing forests, especially plantations. The limitations in China's monitoring program need to be addressed to improve the accuracy of future assessments.

Understanding the drivers ofSoutheastAsian biodiversity loss

Abstract. Southeast Asia (SE Asia) is a known global hotspot of biodiversity and endemism, yet the region is also one of the most biotically threatened. Ecosystems across the region are threatened by an array of drivers, each of which increases the probability of extinction of species in a variety of ecosystems. These issues are symptomatic of the issues that face the global tropics; however, with around 4 billion people in the wider region and the associated pressures on biodiversity, this region may be under some of the greatest levels of biotic threat. Deforestation rates in SE Asia are some of the highest globally, additionally it has the highest rate of mining in the tropics, around the greatest number of hydropower dams under construction, and a consumption of species for traditional medicines which is a threat to biodiversity globally. In this review, the greatest threats to regional biodiversity in the SE Asian region are discussed. Tree-plantations and deforestation represent one of the most imminent threats, and some countries have already lost over half their original forest cover (i.e., the Philippines, parts of Indonesia), with projections of as much as 98% loss for some regions in the coming decade. Hunting and trade represent a significant threat as demand stems not only for food, but also for medicine, for ornamentation, and as a status symbol. Mining represents a frequently overlooked threat, as the Asian region is one of the greatest exporters of limestone and various minerals globally, and the cost of this to biodiversity is not only through the direct loss of areas for mines, but also through the development of roads that further fragment the landscape, the leakage of heavy metals, and the destruction of limestone karsts, which represent global endemicity hotspots. Reservoir construction, wetland drainage, fires, pollution, invasive species, disease, and finally climate change are also considered. Once each issue has been discussed, the overall prognosis of regional biodiversity and priority actions to protect SE Asian biodiversity in the future is discussed.
