“…On the other hand, the unobvious spatial overlap and congruence between biodiversity and phosphorus retention, indicated that biodiversity do not correlated to the service of phosphorus retention. The areas with higher correlation between biodiversity and ecosystem services were found in the high altitude region filled with natural forested in the east mountain with less human disturbance (Liu et al, 2008;Liu et al, 2014). It is known that the carbon sequestration by the upper-elevation forests can mitigate to the global warming changes.…”

Abstract:The significance of biodiversity and ecosystem services are gradually recognized by human as an approach towards sustainability, so it is important to understand relationships and congruence between them to support conservation planning, especially in the hotspot areas with a prominent role in conservation. However, the management of most conservation hotspots mainly focused on biodiversity, and rarely concerned with ecosystem services. With the aim of proposing criteria for conservation strategies that contribute to the optimization of biodiversity and ecosystem services, in this study, a Geographic Information System (GIS)-based approach was designed to estimate and map the biodiversity and ecosystem services in Chongqing Municipality of China. Furthermore, the distributions of hotspot areas for biodiversity and ecosystem services were mapped based on the relationship between cumulative ecosystem services and areas. Finally the statistical analysis was processed focused on specific conservation objectives. The results showed that hotspot areas can conserve the most biodiversity but with the least ecosystem services under the conservation plans target to biodiversity conservation. In contrast, depending on the ecosystem services of interest, hotspot areas can conserve the largest ecosystem services but with the least biodiversity. By integrating biodiversity and ecosystem services into conservation plan, we found that the conservation and regeneration of these small areas, would contribute to a conservation of 44% of the biodiversity hotspot and 14%-42% of the ecosystem services hotspot. Moreover, the current nature reserve selection was not maximize the biodiversity and ecosystem services compared to integration strategy, indicating that hotspot areas conservation and selection is vital for optimization protection of biodiversity and ecosystem services, and has practical significance for natural resources and ecosystem management.

“…FRAGSTATS software measures (McGarigal et al 2012) are widely adopted for fragmentation, estimated using Landsat (Tang et al 2012;Wang et al 2011;Liu et al 2014;Virtanen and Ek 2014;García-Gigorro and Saura 2005), IKONOS-2, GeoEye-1 (Newman et al 2014), QuickBird, ASTER (Virtanen and Ek 2014), or Wide Field Sensor (WiFS) (García-Gigorro and Saura 2005) imagery. Variogram analysis is also employed to assess forest heterogeneity (Cho et al 2012).…”

Remote sensing for biodiversity monitoring: a review of methods for biodiversity indicator extraction and assessment of progress towards international targets

2015

Recognizing the imperative need for biodiversity protection, the Convention on Biological Diversity (CBD) has recently established new targets towards 2020, the so-called Aichi targets, and updated proposed sets of indicators to quantitatively monitor the progress towards these targets. Remote sensing has been increasingly contributing to timely, accurate, and cost-effective assessment of biodiversity-related characteristics and functions during the last years. However, most relevant studies constitute individual research efforts, rarely related with the extraction of widely adopted CBD biodiversity indicators. Furthermore, systematic operational use of remote sensing data by managing authorities has still been limited. In this study, the Aichi targets and the related CBD indicators whose monitoring can be facilitated by remote sensing are identified. For each headline indicator a number of recent remote sensing approaches able for the extraction of related properties are reviewed. Methods cover a wide range of fields, including: habitat extent and condition monitoring; species distribution; pressures from unsustainable management, pollution and climate change; ecosystem service monitoring; and conservation status assessment of protected areas. The advantages and limitations of different remote sensing data and algorithms are discussed. Sorting of the methods based on their reported accuracies is attempted, when possible. The extensive literature survey aims at reviewing highly performing methods that can be used for large-area, effective, and timely biodiversity assessment, to encourage the more systematic use of remote sensing solutions in monitoring progress towards the Aichi targets, and to decrease the gaps between the remote sensing and management communities.

“…Correlation between FLF index with biophysical and antrophogenic factor Human disturbance factors influence on decreasing connectivity of forests as natural habitats (Liu et al 2014), as well as the slope and elevation factors (Simone et al 2010). Ongoing anthropogenic factor can influence structure and composition of forest landscape which borders other uses (Hardt et al 2013).…”
