This paper examines how a biodiversity monitoring system based on data collected by protected area staff and local communities
was established and maintained in Xe Pian national protected area, Laos. Monitoring activities commenced with project support
in 1998. Protected area staff, district forestry staff and villagers continued the monitoring work after 2001 when the external
advisers left. More than 2500 records of wildlife, natural resource use and threats to the protected area were collected by
villagers and protected area staff, mainly through use of patrols, village discussions and village logbooks. The management
interventions that followed the monitoring activities were a reaction to immediate threats or perceived trends in biodiversity
rather than to trends revealed by analyses of the collected data. Patrols and village discussions came to a virtual standstill
when external funding ceased, probably because of lack of supporting national policies. The annual running cost of the monitoring
system was only about US$ 4000 or 0.02 per ha of forest habitat. 相似文献

The need for effective global monitoring of biodiversity is clearer than ever, but our measurements remain patchy and inadequate.
In the biodiversity-rich tropics, a central problem is the sustainability of monitoring schemes. Locally-based, participatory
approaches show promise in overcoming this problem, but may not contribute effectively to monitoring at larger scales. BirdLife
International’s framework for monitoring Important Bird Areas (IBAs) in Africa is designed to be simple, robust and locally-grounded,
but to produce scaleable results that can be compiled into national or regional indices. Focusing on key sites for bird conservation,
identified according to standard criteria, the framework institutionalises monitoring in site management authorities and Site
Support Groups (community-based organisations of local people working for conservation and sustainable development). A small,
central monitoring unit co-ordinates the programme nationally, compiles, analyses and manages data, and provides feedback.
‘Basic’ monitoring (taking place at all sites) involves scoring of state, pressure and response trends using site information
submitted on simple forms. ‘Detailed’ monitoring (taking place at a selected sub-set of sites) involves more intensive measurement
of particular variables that relate to site management targets. IBA monitoring is now underway in at least 10 African countries,
with implementation of the framework most advanced (thanks to a pilot project) in Kenya. The 2004 IBA monitoring report for
Kenya provides extensive information on individual IBAs, plus indices for national trends in state, pressure and response,
based on data from 49 out of 60 sites. The experience in Kenya shows that institutionalisation is vital, but takes considerable
time and effort; that adequate co-ordination (including timely feedback) is key; and that participatory monitoring has many
valuable benefits beyond the data collected. Further work is being undertaken to refine the process, improve its scientific
underpinning, and strengthen the feedback loop from data and analysis to action on the ground. 相似文献

A community-based monitoring system that focuses on natural resource use and forest quality in montane evergreen forest and
miombo woodland areas was developed and implemented in 23 villages in 2002 as part of a participatory forest management regime
in Iringa District, Tanzania. The scheme was developed to suit the needs and capacities of locally-elected natural resource
committees managing and monitoring natural forests. Rather than measuring biodiversity, the monitoring is focused on resource
extraction and disturbance. High levels of commitment to the monitoring were displayed by village level managers, and the
preliminary feed-back indicates that the monitoring scheme provides them with the relevant information needed to suggest appropriate
management interventions. While external support has been essential to cover development costs, natural resource revenue generated
at village level can provide most of the running costs. Once developed, the scheme can, however, be transferred to similar
areas at significantly lower costs that can be met by Tanzanian District budgets. Natural resource revenue generated from
montane forests is generally much lower than in woodland areas due to restrictions on resource extraction imposed as a consequence
of national and international interests. Opportunities to provide economic incentives for montane forest managers through
direct utilisation of the resource are limited and it remains to be seen whether other non-economic incentives can sustain
long term commitment in these biodiversity rich areas. Findings indicate that the key elements of this local resource utilisation
monitoring scheme are simplicity, incentive mechanisms, transparency and accountability, and autonomy for local managers.
However, the methods may not provide sufficient data on changes in biodiversity values in the high value forests and may need
to be augmented by conventional monitoring by scientists funded by national or international institutions. Elements of the
scheme are now being institutionalised within the forestry sector in Tanzania. 相似文献

A phosphatized bilaterally symmetrical, spirally coiled conch from the Lower Cambrian phosphates of the Meishucunian Stage of eastern Yunnan, China, is composed of two well-preserved layers. The outer one is built of longitudinal mineralized fibres not strictly parallel to each other, but may anastomose or branch. The fibres form comarginal ribs with transversal grooves between them, corresponding to growth stages. In the ribs, the fibres are arranged closely and are steeply inclined towards the apex, while in the grooves the fibres are subparallel to the conch surface and more loosely packed. Small elliptic and triangular holes are situated within and between the fibres of the outer layer. The inner layer consists of transversal fibres running around the conch. They are almost parallel to each other but partly separated by narrow discontinuous slits. Despite overall morphological similarity of the conch to shells of some early Cambrian molluscs, the observed orthogonal configuration of longitudinally oriented fibrous structures of the outer layer and transversal fibres of the inner layer is found in orthothecid hyoliths, phosphatized microstuctures of which have been described from the Lower Cambrian of the Siberian Platform. The new material from the Yangtze Platform supports a conclusion of a distinctive type of microstructure available in hyoliths different from molluscan microstructures available from the Lower Cambrian. 相似文献

An investigation of gamasid mites on the body surface of small mammals was carried out in Yunnan Province of China from 1990 to 2004. The small mammal hosts were captured from 25 counties which represent five geographical subregions, namely Middle Subregion of Hengduan Mountains, Southern Subregion of Hengduan Mountains, Eastern Plateau Subregion of Yunnan, Western Plateau Subregion of Yunnan and Southern Moun- tainous Subregion of Yunnan. The captured 10 803 small mammal hosts belong to nine families, 29 genera and 52 species in four orders (Rodentia, Insectivora, Scandentia and Lagomorpha). A total of 68 571 gamasid mites were collected from the body surface of the captured small mammal hosts and all the gamasid mites were identified to 10 families, 33 genera and 112 species. This paper lists all the mite species, together with their taxonomic position (genera and families) and their corresponding hosts. Much more mite species were found in the Middle Subregion of Hengduan Mountains than in other geographical subregions. The total individuals of mites and small mammals in the Middle Subregion of Hengduan Mountains are also the most plentiful in the five geographical subregions. Three dominant mite species and three dominant small mammal hosts were determined as the dominant species in the investigated areas of Yunnan Province. The dominant hosts are Rattus flavipectus (which accounts for 34.85% of the total individuals), Apodemus chevrieri (13.43%) and Rattus norvegicus (10.40%) while the dominant gamasid mite species are Laelaps nuttalli (Hirst, 1915) (27.84%), Laelaps echidninus (Berlese, 1887) (18.38%) and Laelaps guizhouensis (Gu et Wang, 1981) (14.79%). The results showed the high species diversity of gamasid mites in Yunnan Province and the uneven distribution feature in different subregions. 相似文献

This paper reports the main findings of a study on the factors threatening biodiversity in northwest Yunnan, a global biodiversity hotspot in China and home to over five million people. The research was based on eight site-level case studies. The main driving forces of biodiversity loss are livelihood activities, including agricultural production, livestock grazing and the collection of fuel wood, construction timber and NTFPs. Behind these specific drivers are underlying factors including changes in demography, market conditions, resource tenure policies and development policies and projects. Some change in land cover has been due to specific trigger events, the most significant of which reflect national policy changes. At the site level, a range of biophysical and socio-cultural factors influence the specific outcomes that any particular factor may have. The paper suggests some specific redressive measures and general implications for research and policy. 相似文献
