WORKING GROUP
THIRD ANNUAL REPORT TO CCICED

Importance of China's biodiversity
Definition: Biodiversity is taken to include the entire genetic content and all ecological functions processes and structures of the fauna and flora of China.
Overview: China's biodiversity is the third richest in the world, and richer than any other Asian or¡¡ temperate country. This wealth of species and populations is explained by very large size, extreme in the world. Major ecosystems include 1) forests, that range from temperate to tropical (10%), 2)climatic and geographic variation, long continental stability and the most extensive subtropical zone extensive high altitude grasslands and alpine systems (60%), 3) extensive steppe grasslands and deserts (15%), 4) important rivers, lakes and wetland systems, 5) rich marine and coastal areas and 6) agricultural land (11% of total area).
However, China has the world's largest human population, including both some of the world's most densely populated and intensively cultivated areas and also some of the most desolate and unpolluted regions of the planet. The dependence of the human population on direct and indirect benefits and services derived from biodiversity is enormous. The reason China has been able to sustain this high population is directly related to its reliance on its biological resources over 1500 years of ecosystem management. A first attempt to list and evaluate the major benefits are given below.
It is the conclusion of the Biodiversity Working Group that the full range and importance of these benefits and services are not currently appreciated by policy-makers and planners in the national and provincial governments, nor by technical planners in sectoral ministries and certainly not by the general public. As a result (1) major policy errors are being made - totally inadequate attention is being paid to protection of biodiversity and thereby the benefits derived from it; (2) inadequate investment is being made in research and manpower development; (3) inappropriate decisions are being made with regard to land-use; (4) inappropriate technology is being applied in areas of forest restoration and range management; (5) inadequate measures are being taken to control over-use and depletion of natural resources, pollution controls, wasteful use practices, and (6) inadequate compensation charges are levied on the damages of natural ecosystems.
This report lists the main benefits being derived from various ecosystems in China, the main threats and problems jeapordising the sustained flow of such benefits and specific recommendations for containing these threats. The two over-riding recommendation, however, remains the same as this group made to the council two years ago, namely that China is not taking the destruction of its biodiversity seriously enough and that public awareness is the most important need to raise the levels of attention and investment.
I. Benefit and Services derived from Biodiversity
The working group has tried to clarify exactly what these various short and long-term benefit deriving from biodiversity are. The two tables below indicate firstly what kinds of benefit are derived from each major ecosystem type and secondly what these benefits might be worth in economic terms to the Chinese and global economies. The evaluations are of necessity crude and are given wide estimate ranges. Many of these values will grow as the standard of living grows. Others are only a small fraction of their ultimate potential.

Notes
explaining the logic and calculation of these values are given in annexe 1.
of this report.
Tables 1 and 2 illustrate
the of enormous economic benefit of biodiversity to China. Three points are
worth highlighting. (1) The value of environmental services of natural vegetation
are much higher than the actual harvested resource values. (2) Wildlife's chief
value is in its keystone role of maintaining floral communities in balance.
(3) The value of forest is usually many times greater than the value of its
timber.
A proportion of the
agricultural and animal husbandry production in China must be credited as a
major biodiversity service since all the germplasm used is derived from biodiversity,
all improvements, new domestications and technological improvements to agricultural
crops and stocks will depend on the continued preservation of China's biodiversity.
This is like the payment of copyright or insurance in other branches of the
economy.
The world has wider
benefits deriving from China's biodiversity in the form of germplasm of rice,
wheat, barley, kiwifruit, tea and domestic animals. Equally, China benefits
from many externally derived sources of biodiversity such as potatoes, maize,
sugar, rubber, oil-palm, eucalyptus etc.
It is quite clear
that unless actively protected all forests and natural landscapes would be destroyed
through overuse in the next few decades. The cost of protecting the natural
systems that provide such benefits is easily justified. However, at present
there is an unwillingness to pay these costs perhaps because of an underappreciation
of these services. The various ecological systems of the country face different
threats and these need a variety of solutions. The following section lists these
problems and the groups specific recommendations for remedial actions.
II. Forests Ecosystems
Forests cover
10% of China's land surface. At present they are managed almost entirely on
the basis of timber production. However, with appropriate ecosystem management
they provide a much wider and more valuable range of economic and social benefits.
The Biodiversity Working Group (BWG) has identified major threats to the productivity
of forest systems and lists remedial actions necessary to solve these problems.
Many of these actions are already being tackled and have already been identified
in such reviews as the China Biodiversity Conservation Action Plan (1994). We
add some more detailed recommendations of the most important of these.
THREATS
III.
Grassland Ecosystems
China's grasslands and alpine systems cover about two thirds of the entire country including the very extensive Xizang-Qinghai plateau and northern steppes. Their primary productivity creates food for grazing mammals (domestic and native). But the natural small burrowing mammals (pikas/zokors) - are just as important in recycling of nutrients, aeration of soil, increased plant species richness which in turn increases ecosystem stability; reduces erosion; hydrological stability. These areas have important potential for ecotourism. Zokor bones can be used as a substitute for tiger bones and therefore have the added benefit of reducing exploitation of another endangered species. There are other aesthetic, scientific, ethical (religious) values dependent on the maintenance of these ecosystems.
THREATS
REMEDIAL ACTIONS NEEDED
RECOMMENDATIONS
Lakes and rivers are of great importance to humans in China. In good health and with regulated hydrology they provide living places, modes of cheap transport, water, irrigation systems and fish, and are enjoyed for recreation and tourism. Unregulated they are dangerous, destroy agriculture and property, silt up expensive hydropower and irrigation developments, etc. The health and regulation of these systems depends on proper watershed and ecosystem management.
THREATS
REMEDIAL ACTIONS NEEDED
V.
The Marine Environment
China has a very
large marine area that has been important for fisheries, coral reefs and other
products (shells, turtles, seaweeds etc.). The coastline and marine areas also
have enormous recreational and touristic potential. Coastal ecosystems such
as corals and mangroves serve an important function in protecting the coastline
from sea erosion and preservation of highly productive fishing areas and prawn
spawning areas. However, it is clear that marine fisheries are crashing in Chinese
seas and pollution is causing loss of corals and other communities.
THREATS:
REMEDIAL ACTIONS NEEDED:
The Working Group has not yet conducted any specific studies on the marine ecosystem so have not yet formulated any specific recommendations to the Council.
VI.
Agricultural Systems
A total of 11% of the land area of China is used for agriculture. This area feeds over one billion people. On these lands are maintained the most valuable items of biodiversity harnessed from nature. Protecting the full range of domesticated varieties is important for the future of agricultural development and technological improvement. There is a dangerous tendency to abandon "inferior" varieties in favour of new more productive strains. However, many local varieties contain important genes and adaptations to specific local conditions or resistance to disease which are of enormous value for future crop improvement work.
THREATS
REMEDIAL ACTIONS NEEDED
RECOMMENDATIONS
Pay more attention to indigenous knowledge which is very valuable to biodiversity management. There are many minority nationalities in China, each with its own traditional knowledge of plants, agriculture and forests which is quite valuable to biodiversity management and sustainable development. In recent years, international funding agencies and scientists have paid special attention to the study and application of indigenous knowledge on biodiversity, but the government and foundations of China still pay little attention to this issue.
Other Technical Issues Relevant to Biodiversity Conservation
VII. Biodiversity Information Management
Ecological
systems are extremely complex. In order to make informed decisions about the
management of ecosystems, watersheds, and landscapes, one needs biodiversity
databases built on reliable and accurate data of species distributions, geographical
information, and regulatory controls. This is done by building databases of
information on geography, species, vegetation, management, etc. and using these
data to predict outcomes of management proposals or climatic change. The establishment
and maintenance of biodiversity databases is critical to make informed, economically
viable decisions.
Biodiversity databases are important because they are:
1. The basis of knowledge,
attitudes and decisions.
2. Important for estimates on socio-economic values, threats, and strategies.
3. Basis for biodiversity prospecting (discovering of new medicines).
4. Good Environmental health indicators
5. Good predictors of climatic change
6. The basis for ecosystem management
7. The sole record of China's rich natural heritage
RECOMMENDATIONS
1. Maintenance and Preservation
of Biodiversity Collections
Over the last
decade, much progress has been made in development of biodiversity databases.
However, in most cases, little or no attention has been paid to the source of
the original data for the information management - the specimens in zoological
and botanical collections. The taxonomies used are inconsistent, there is little
or no funding for the preservation and maintenance of the collections, and many
collections are deteriorating rapidly. These collections need to be reviewed,
in many cases brought up to professional standards, and supplied with adequate
funding to keep the only record of China rich natural heritage and biological
wealth.
We propose:
2. Increased Emphasis
on Systematics and Taxonomy
A lack of trained
systemists and taxonomists in China is a major constraint in China's ability
to monitor its biodiversity and limiting its capacity to absorb international
systems and cooperation in biodiversity management. Incentives must be found
to make these areas more attractive to young scientists.
We recommend:
3. Expansion of Biological Inventories and Monitoring Programs.
Because of the lack of adequate numbers of trained systematists and taxonomists, the basic data collected from inventories is often inadequate, out of date, and in some cases improperly collected. This will promote poor management decisions, discourage international sources of help, and in some cases lead to the detriment of the very species one is trying to protect.
We recommend:
VIII. Ex-Situ Conservation Needs
The working group is concerned that Chinese authorities are placing too much emphasis on ex-situ methods of conserving wildlife. There have been a few successes such as rescue of doomed populations of crested ibis, Yangtze alligator and reintroduction of captive bred Pere David's deer. But there have been expensive failures such as the breeding programme for giant pandas and Yangtze river dolphin (baiji). Ex-situ conservation is very expensive, often not successful and globally very few successful reintroductions have been achieved. Most plans to construct new breeding centres for rare pheasants, deer, primates and carnivores in China appear to be motivated by commercial rather than conservation motives. Most zoo examples of ex-situ conservation in China are mainly for exhibition and commercial hopes and are completely negative for conservation. The standards of most Chinese zoos are so poor that these constitute a national embarrassment and a constant source of international protests.
By far the best and cheapest way to save species en masse is by in-situ conservation of their entire ecosystem. Ex-situ conservation should be seen only as an insurance to maintain a captive genepool in the event a species becomes extinct in the wild. The primary function of zoos should be for public awareness and education. At present, there is little or no emphasis on this in China's zoos. Some zoos have reduced their education work because it does not add revenue. Cruel display of animals solely for public amusement gives out the totally wrong public awareness message and should be halted.
Ex-situ conservation of plants is more feasible. Plants need less space and are cheaper to maintain than animals. Reintroduction to the wild is much easier. Standards of botanic gardens in China are much higher than of zoos. About 120 botanical Gardens (arboreta) have been set up in China, currently cultivating about 18,000 species of China's flora accounting for 65% of the total species listed in the first batch of protected plants. This is a significant contribution to the ex situ conservation of plant diversity in China.
RECOMMENDATIONS
1. Programs are
needed to set up some new botanical gardens as well as emphatically support
the botanical gardens which have better foundations in order to achieve the
goal of ex situ conservation on rare and endangered plants as proposed in the
"China Biodiversity Conservation Action Plan". A coordinating authority
should be set up to supervise this programme on the basis of a national botanic
garden strategy.
2. The China Zoo Association is urged to draw up a national strategy
for zoos in China on the basis of the global zoo strategy of IUCN. Emphasis
should be placed on improving standards of care to reach self sustained captive
populations. Primary objectives of the strategy should be public education and
awareness, not ex-situ conservation. Standards should be defined. Those
zoos unable to meet the standards should be closed down and refused further
permits to acquire new animals. Zoos should be free to raise gate prices to
pay for the improvements needed.
3. Ex-situ conservation strategies for endangered species should
only be developed in the context of overall species survival plans for the species
in the wild.
IX. Wildlife Trade Issues
While China has been famous for its trade in wildlife for food and medicine for thousands of years, the time has come when these revered traditions are no longer sustainable by nature. There is no longer enough biodiversity remaining in China - and perhaps the world - for all of China's 1.3 billion people to enjoy the unmitigated use of plants and animals as food, medicine and other consumer products in a sustainable manner. If wildlife trade in China is not more strictly controlled soon, it will be the cause of major losses of what biodiversity remains in China and perhaps extinctions of entire species.
In order to ensure that wildlife trade in China is sustainable and does not destroy the biodiversity of China or her neighbours, the following measures must be taken urgently:
1. A biological
inventory of China's wild animals and plant populations. Without inventories
conducted by strict scientific standards, sustainable use levels cannot be accurately
determined.
2. A review of the entire Chinese pharmacopoeia to establish which wild
plants and animals are essential to public health in China and which are being
used in high volumes with serious impact on the wild population. This review
should be used to predict which wild animals and plants are in need of immediate
conservation attention and regulation to avoid endangerment due to high volumes
of trade for medicinal purposes and promote sustainability.
3. A review of government-held trade statistics to document rates of
consumption of any and all wildlife products used in commercial trade. Until
now, with a couple of exceptions, these statistics either have not been made
available or have not been examined.
4. Strict regulation for the marking and selling of wildlife products
from farming or captive breeding operations to ensure that wild-collected animal
and plant products are not "laundered" as captive bred.
5. An accurate and detailed analysis of wildlife farming and propagation
as a conservation tool. Does wildlife farming really take pressure off of
wild populations or does it simply stimulate demand and open opportunities to
launder wild-collected specimens?
6. More undercover investigations by government authorities to stop
black marketing of protected species. These investigations should be investigated
with the same methods used for interdiction of narcotics trade.
7. Training of border officials for identification and interdiction of wildlife
in trade. A number of foreign organizations and agencies are keen to assist
with training workshops and identification materials. This should be conducted
at the local or provincial level, rather than from the central government down,
because regional needs are both immediate and, in some cases, quite different
from those of other regions.
8. More stringent inspection procedures at all border points, especially
those known as entry or exit points for wildlife, such as the borders with Hong
Kong, Mongolia, Russia and Vietnam.
9. Government trade quotas for non-protected species to ensure
sustainability of commercial trade, especially of those identified as key species
for medicine, food and other popular commercial uses.
10. Financial and political incentives for research and production of acceptable
substitutions for wildlife derivatives, especially traditional Chinese medicine.
11. A government campaign to inform traditional medicine specialists and
consumers of their role in saving China's and the world's biodiversity.
This would entail a positive message to tell them their help is essential to
the effort to save some of their country's most valuable assets for reasons
of not just beauty, but economic stability and to make China a responsible citizen
of the world. In other words, what they buy does make a difference to China
and to the world.
12. Host a wildlife trade symposium with neighbouring countries to develop
better trade controls. A total wildlife trade ban is recommended between China
and Vietnam. The customs authority should cooperate more closely with forestry
authorities to control wild-life trade.
13. Establish regulations to avoid invasion of exotic species.
Regulations are needed to regulate the confiscation of illegally traded species
and releasing them into nature to prevent the release of unwanted exotics and
to regulate the breeding of exotic species to avoid their escape to the wild.
X. Public Awareness
Attitudes towards nature are currently focused on selfish utilization over the short term only. Members of the public, nature reserve staff, local governments and state policy makers are not yet convinced of the long-term values of biodiversity. Public awareness will lead to stronger support for the establishment of policies and respect for the policies once established.
REMEDIAL ACTIONS NEEDED
1. Persuade state
to change school curricula.
2. Provide data, information, etc. to improve understandings and attitudes.
3. Promote reflection on China's long past for an improved long view
of the future in all work on biodiversity values and recommendations.
4. 'Expect The Best' - of China, its state council, its government staff
and the people.
5. Ask for the assignment of P.A. tasks to selected groups, agencies,
persons.
6. Translate existing
wildlife films, books, etc. into Chinese.
7. Use Chinese zoos and Botanical Gardens to better educational effect.
Note: There are about 120 botanical gardens (aboreta) and about 170 Zoos established in China which receive about 120,000,000 visitors per year. These must be primary candidates for development of public education on biodiversity and its sustainable development. The botanical gardens and Zoos in China, however, mostly lack facilities for education. In order to improve educational conditions the governmental agencies should give special funds for public education programs.
MAJOR CONCLUSIONS OF THE BIODIVERSITY WORKING GROUP
1. It is clear that
the real scale of values and benefits derived from biodiversity to the Chinese
economy and society are unrecognized and under-appreciated by both the general
public and government. The threats to those benefits are also not fully appreciated.
This lack of understanding is leading to major policy errors that will cost
the nation billions of dollars in the future. This is not merely a question
of preferring short-term benefits to long-term benefits. The benefits from biodiversity
are being gained on the short-term on an enormous scale (crudely estimated at
between 200-450 billion US$ per year.
2. A serious policy error consists of viewing forest as primarily for
timber production and therefore planning reforestation (in a massive and expensive
manner) in terms of future timber yields instead of the more valuable restoration
of ecological function (which can be achieved cheaper and faster). Indirect
benefits to agriculture are more important that timber (we can find alternate
materials for construction and furniture but we cannot find alternates to food).
Provincial regreening and reforestation programmes should be supervised by a
committee with representation from all concerned bureaus not determined solely
by Bureau of Forestry.
3. A second major policy error is the mistaken belief that productivity
of grassland systems can be increased by simply boosting livestock levels and
by conversion to agriculture. These systems are fragile and have a limited sustainable
production. They can be pushed over their natural capacity only for short periods
after which they degrade fast and take centuries to rebuild their original soil
fertility. China should learn from the errors made in Central Asia, India and
parts of Africa where overgrazing has already led to massive desertification.
Thousands of years of Chinese pastoralism by local people have determined "safe"
production levels for these lands. As with forests, the greatest values of these
lands are their ecological services not their harvested resources. Only minor
improvements can be achieved sustainably.
4. Other policy errors concern the lack of consideration to damage to
wetland, freshwater and marine systems by land developments and industry.
5. Such policy errors are caused by lack of awareness and will continue
to be made as long as the true values of biodiversity services remains unappreciated.
The solution to the problem is a massive national awareness campaign through
the formal education system, mass media, local interest groups and non-government
organizations and special courses for government officials.
6. Underappreciation of the benefits derived from biodiversity and the
serious levels of threat faced by biodiversity continue to result in totally
inadequate investment in biodiversity protection. Major increases in national
budgets for development of nature reserves are largely wasted as a result of
a poor understanding of protection needs. Large sums of money have been spent
on unnecessary buildings often far from the reserves and manned by unnecessary
management staff. Almost no funds have been invested in improving the effectiveness
of the guardforce. The training given to reserve managers is also deficient.
7. China faces a growing problem in the lack of new taxonomists. This
discipline is clearly not seen as attractive to young scientists but it is crucial
to China's ability to monitor and regulate biodiversity in the future. Some
way to create more incentive for entering this discipline must be found. Too
much emphasis is placed on developing fancy and expensive GIS and database systems
and not enough emphasis on actual data collection, quality and maintenance of
collections.
8. China could improve its performance in international arenas of biodiversity
conservation by being more active and participatory in programmes. More technical
expertise rather than foreign relations skills should be included in representative
teams. In return China could get far more out of these programmes through a
fuller participation. Many funding opportunities are being lost through a stand-back
approach.
