LAND COVER and LAND USE CHANGES UNDER FOREST PROTECTION and RESTORATION in TIANTANGZHAI TOWNSHIP, ANHUI, CHINA Qi Zhang a Thesis LAND COVER AND LAND USE CHANGES UNDER FOREST PROTECTION AND RESTORATION IN TIANTANGZHAI TOWNSHIP, ANHUI, CHINA Qi Zhang A thesis submitted to the faculty of the University of North Carolina at Chapel Hill in partial fulfillment of the requirements for the degree of Master of Arts in the Department of Geography. Chapel Hill 2014 Approved by: Conghe Song Xiaodong Chen Lawrence Band © 2014 Qi Zhang ALL RIGHTS RESERVED ii ABSTRACT QI ZHANG: Land Cover and Land Use Changes under Forest Protection and Restoration in Tiantangzhai Township, Anhui, China (Under the direction of Conghe Song) Deforestation and forest regeneration are two key changes in the forest ecosystem that have profound impacts of the goods and services in terrestrial ecosystem. In late 1990s, China implemented Sloping Land Conversion Program (SLCP) and Natural Forest Protection Program (NFPP) aimed at forest protection and restoration. Using archived historical images, this study compared the land-cover/land-use (LCLU) changes before and after the programs and developed remote sensing indices to characterize the growth trajectory of “Grain-For- Green” (GFG) and natural forests. The results indicate substantial increase of natural forest cover during 2002-2013, compared with that during 1992-2002. The proposed indices revealed aggradation for both NFPP and GFG forests since the implementation of these policies. Further analysis found spatial variation of forest development depends on the topographic factors. This study reveals that SLCP and NFPP have been improving forest growth and development in the study area since the implementation of these policies. iii ACKNOWLEDGEMENTS I take this opportunity to express my profound gratitude and deep regards to my advisor, Dr. Conghe Song, for his exemplary guidance, monitoring and constant encouragement throughout the course of this thesis. I offer my sincere appreciation for the learning opportunities provided by Dr. Lawrence Band and Dr. Xiaodong Chen for their advices throughout the research. My completion of this project could not have been accomplished without the support my research group members: Matthew Dannenberg, Yulong Zhang, Chris Hakkenberg and Chong Liu. The discussions with them provides me with great thoughts in processing remote sensing data and interpretation of results. Thanks also to the support of Matthew J. Burbank summer research fellowship from graduate school of UNC, which provided me the opportunity for data collection during summer 2013. I am also deeply grateful to my parents for their help and guidance for my life.

This taxon is distinguished from its closest relatives by unbranched paraphyses and asci with truncate or subtruncate apices. The type specimen is deposited in the Reference Collection of Forest Fungi of Anhui Agricultural University, China (AAUF). Key words —taxonomy, Ascomycota, morphology, vine plant Introduction The genusTerriera B. Erikss. was established by Eriksson (1970) for T. clado- phila (Lév.) B. Erikss., belonging to Rhytismataceae (Kirk et al. 2008). Minter (1996) provided a detailed description of the type species. Over the years, however, some species which should belong to Terriera have been mistakenly placed in Clithris (Fr.) Bonord., Dermascia Tehon, Hypoderma De Not., and (particularly) Lophodermium Chevall. (Johnston 2001). Johnston (2001), who divided Lophodermium on monocotyledonous plants into groups A, B, C, and D, regarded Group B species as closer to the type species of Terriera based on their special ascomatal structure. He therefore transferred 11 species and 1 variety of Lophodermium Group B to Terriera as new combinations and published three new species. The author also invalidly published a fourth species, in that work, which he later validly published as T.

It is characterized by elongated ellipsoidal to cylindrical conidia, solitary conidiogenous cells that are cylindrical or with slightly swollen bases, white to pale pink colony in culture, and small mycelial pellets consisting of curved hyphae. Phylogenetic analyses of translation elongation factor-1 alpha (TEF), RNA polymerase II largest subunit (RPB1), and RNA polymerase II second largest subunit (RPB2) sequence data support it as a unique species and sister to B. sungii. It does not, however, form a monophyletic group with other elongated ellipsoidal to cylindrical conidia- producing species in Beauveria. Type isolates and holotype are deposited in the Research Center for Entomogenous Fungi of Anhui Agricultural University (RCEF). Key words —Ascomycetes, taxonomy, entomopathogenic fungi Introduction Beauveria Vuill. is a globally distributed genus of soil-borne and entomopathogenic hyphomycetes. It is of particular interest as a model system for the study of entomopathogenesis and the biocontrol of pest insects (Rehner & Buckley 2005).

  • White-Eared Night Heron Gorsachius Magnificus in China
    Bird Conservation International (2007) 17:93–101. ß BirdLife International 2007 doi: 10.1017/S0959270906000566 Printed in the United Kingdom An update on the distribution of the ‘Endangered’ White-eared Night Heron Gorsachius magnificus in China HE FEN-QI, JOHN R. FELLOWES, BOSCO P. L. CHAN, MICHAEL W. N. LAU, LIN JIAN-SHENG and LEE KWOK SHING Summary The literature on the past distribution and status of the White-eared Night Heron in China is reviewed, and updated based on recent field investigations and reports from Hubei, Jiangxi, Guangxi, Guangdong and Hainan. Recent records reveal the species to be more widespread than previously thought, but there remain many uncertainties about the area of occupancy and connectivity between known populations. The rate of discovery of new sites suggests the species may be under-recorded, but a number of recent sites have been lost, and no truly secure populations are known. There thus remains an urgent need for better information from throughout the species’ range, especially from historical sites, as well as increased protection. Introduction Since its discovery at Wuzhishan, Hainan Island, in 1899, the White-eared Night Heron Gorsachius magnificus has been recorded from eight provinces in southern China, together with two records from north-eastern Vietnam (BirdLife International 2001, 2004; He and Lin 2004). Until the end of the twentieth century, the recorded distribution of White-eared Night Heron in mainland China formed a horseshoe shape, with an empty core in the provinces of Jiangxi and Hunan (Figure 1). Available records suggest the species has a highly fragmented distribution and is extremely rare.

ZooKeys 321: 89–96. doi: 10.3897/zookeys.321.5752 Abstract The female of Sinopoda serrata (Wang, 1990) is described for the first time from Tiantangzhai National Forest Park, Hubei province, China. This species has been recorded from the region of Central China. Morphological descriptions and illustrations of this species are given. Keywords Taxonomy, biodiversity, systematics, huntsman spiders Introduction The spider genus Sinopoda Jäger, 1999 is distributed in East Asia and northern parts of South East Asia with 49 species described so far, 32 of which are known from China (Jäger 2012, Platnick 2013). The species Sinopoda serrata (Wang, 1990) was first described in Heteropoda La- treille, 1804, based on male specimens only from Mt. Lushan (Jiangxi Province, Chi- na) and Mt. Huangshan (Anhui Province, China) (Wang 1990). Jäger (1999) trans- ferred this species to the genus Sinopoda. Recently, the authors examined specimens collected from Hubei Province and found that 2 females and 7 males seemed to be this species based on comparison with the type specimens.

ABSTRACT Although myxomycetes are ubiquitous in terrestrial ecosystems, studies on their distribution and diversity in subtropical humid forests are still lacking. Field collections and moist chamber cultures were conducted from May to October within a two-year period in the Tiantangzhai National Forest Park of China. A total of 1,492 records representing 73 species belonging to 26 genera were obtained, of which 243 records/37 species were from field collections, and 1,249 records/52 species were from moist chamber cultures. Among the specimens obtained by culturing, 896 records/38 species and 353 records/37 species were obtained from living bark and ground litter, respectively. ANOVA showed that the sampling months had significant impacts on collection of myxomycetes from field and those that inhabit litter. An LEfSe analysis indicated that Arcyria was significantly abundant in August, while Stemonitis and Physarum were more abundant in July when collected from field.

Chapel Hill 2017 Approved by: Conghe Song Richard Bilsborrow Xiaodong Chen Pamela Jagger Stephen Walsh ©2017 Qi Zhang ALL RIGHTS RESERVED ii ABSTRACT QI ZHANG: Social-ecological impacts of China’s Payments for Ecosystem Services Programs on land use, migration and livelihoods (Under the direction of Conghe Song) Payments for ecosystem services (PES) has emerged as an innovative approach to address the problems in the human-environment nexus. Understanding the ecological and socio-economic impacts of PES programs is essential to the sustainability of environmental goods and services conserved by these programs. The Conversion of Cropland to Forest Program (CCFP) and the Ecological Welfare Forest Program (EWFP) were among the major PES programs initiated in China in the late 1990s. This dissertation draws on data collected from household surveys to investigate human adaptation to the socio-economic and environmental changes in Tiantangzhai Township, Anhui, China, where both CCFP and EWFP were implemented. I found that the PES programs, together with other factors, both directly and indirectly affected cropland abandonment, individual out-migration and rural livelihoods. Proximity of land parcels to the nearest CCFP and EWFP forests increases the likelihood of cropland abandonment.

Received: 7 December 2019; Accepted: 8 January 2020; Published: 12 January 2020 Abstract: Tourism and agriculture can contribute to destination sustainability by increasing tourist-stakeholder satisfaction. Grown agriculture is an important component of a rural destination attraction. Nonetheless, tourists’ satisfaction with locally grown agricultural food has been unexplored when it comes to linking tourism with agriculture. The purpose of this study is to develop an understanding of the links between demand for locally grown agricultural products at the destination and the levels of satisfaction among visitors. Theoretical views concerning tourist consumption of local agricultural products and its effects were reviewed. Unstructured in-depth interviews were conducted onsite in Tiantangzhai to investigate the relationship between tourism and agriculture with visitor satisfaction. The sample of respondents consisted of 71 participants who shared their views on the relationship between agriculture and tourism at the destination. Findings were presented in a two-level analysis including the industry focus and a soft-laddering technique that revealed deeper insights.

Here, we developed a spatially explicit agent- based model based on spatial and socioeconomic data to simulate households’ land and labor allocation de- cisions and investigated the impacts of two forest restoration and conservation programs and one agricultural subsidy program in rural China. Simulation outputs revealed that the forest restoration program accelerates labor out-migration and cropland shrink, while the forest conservation program promotes livelihood diversi- fication via increasing non-farm employment.

  • A Survey of the Birds of the Dabie Shan Range, Central China
    FORKTAIL 24 (2008): 80–91 A survey of the birds of the Dabie Shan range, central China YANG LIU, ZHENG-WANG ZHANG, JIAN-QIANG LI, YU ZHANG, SHAN LU and XIANG-FENG RUAN The Dabie Shan (Dabie Mountains) range, straddling Henan, Hubei and Anhui provinces in central China, harbours a rich bird diversity, representing a transition between Palaearctic and Oriental realms. Although historical information is available on the avifauna of this region, no recent comprehensive bird survey has been carried out. In this paper we present a bird inventory study for the Dabie Shan range based on ornithological surveys conducted between 2004 and 2006. We recorded 238 bird species during these surveys. Species of conservation significance include Falcated Duck Anas falcata, Reeves’s Pheasant Syrmaticus reevesii, Baer’s Pochard Aythya baeri, Fairy Pitta Pitta nympha, and Brown-chested Jungle Flycatcher Rhinomyias brunneata. Ten species are new records for the Dabie Shan range. This region is notable as a transition zone, in that most winter visitors and migrants are Palaearctic and a large proportion of summer breeders are Oriental species. It is also the northernmost part of the range of a number of subtropical breeders in China. The avifauna is threatened by extensive habitat loss outside the protected areas of the range, and we discuss conservation recommendations for the whole region. INTRODUCTION information on species of conservation concern to inform reserve managers at the regional level, and to improve our The Dabie Shan (Dabie Mountains) range (30°02′– knowledge about the distribution of these species. The 32°20′N 114°30′–117°05′E) lies in a transition zone third purpose of our investigation was to document the between the Palaearctic and Oriental regions in China, avifauna of a few places which had received little or no and so is crucial to our understanding of biogeography of prior ornithological attention.
