Tasting the peat Tasting five thousand year old peat? Unless you have not eaten for five thousand years, peat is not a tasty food item. But this is exactly the stuff ECBPâ€™s Carsten Germer, Shi Jianbin and Lu Hefen were asked to taste by Mr. Chen Kelin - Director of Wetland International in China, during their recent monitoring trip to the Rouergai Marshes in the Qinghai-Tibetan Plateau. The trio attended the annual meeting of the Wetland International project in Luqu County, Gansu province Aug.7-14, 2009.

taken by Wetland International (with a second field site in the Altai Mountains in Xinjiang Province). After a year of building dams, blocking canals and controlling desertification, restoration of the peat and marshland is showing impressive initial results: water on parts of the marshes is trapped and water level raised. Thus grassland has recovered and water storage capacity improved. Although peat can never make it on the list of anyoneâ€™s favorite food items and is itself 90% water, the odorless, tasteless, brownish-black, organic matter provides key habitat for some endangered wildlife species, forms a vital reservoir as the catchment for streams and rivers (including both the Yellow River and the Yangtze), and maintains grassland for local livelihoods and biodiversity. It also provides important

for thousands of years tended yaks and sheep on this vast piece of highland. But their life style is changing due to natural and man-made reasons. Large areas of peatlands were drained in the 1960s and 1970s to expand potential access to grazing animals. As a result the water storage capacity of the peatlands has been severely impacted leading to significant reduction in local groundwater tables, deterioration of pasture quality on adjacent dry-lands and to reduced dry season water availability. This has led to increased pressure on the remaining peatlands and many of them are now severely impacted through heavy grazing pressure. Many people have become semi-nomadic and the numbers of their herds have had to be reduced.
The moist grasslands support a wealth of alpine flowers but autumn frosts are just around the corner.

Nevertheless it is still not too late. There are still carpets of edelweiss, and in summer the meadows are a mass of colours of alpine flowers â€“ blue gentians and delphiniums, yellow Potentilla and louseworts. Frogs and dragonflies enjoy the wetlands. Falcons and eagles prey on the many pikas and marmots that live in large colonies among the grasslands and wolves still find a living in this large wilderness. This is the main breeding area in Edelweiss (Leontopodium) China for
the endangered Black-necked cranes. Many other wetland species live here such as Ruddy shelduck, spotted redshank, plovers and wild geese. Preserving the wetlands makes a lot of sense both locally and in terms of protecting valuable national and global resources. The ECBP project mobilizes local govern-
Summer bounty on the plateau ment and local communities to understand the benefits and take the measures needed to prevent the drainage and degradation of these fragile lands. Benefits include improved pasture, opportunities for eco-tourism, biodiversity conservation, improved water conservation and storage of a huge amount of carbon in the efforts to limit climate change.

But the wetlands are huge and span parts of three provinces, so it was a long and sometimes arduous trek in jeeps from one county another and a heavy toll of meetings to discuss progress, funds spent, plans of action and inspection of works in the field. Meetings were punctuated with feasts of animal meat washed down by bowls of 5-grain liquor in typical Tibetan hospitality. Maybe in retrospect eating the peat was the least of our worries.
We got off the plateau before the bite of autumn closed down and enjoyed a final day admiring the beauties of Huanglongshan whilst waiting for our flights back to Chengdu and thence Beijing.
Carbon stored in peatlands in China is more than that stored in all its forests. But peat will burn or rot if allowed to dry out.

The major attraction of the 60,000ha Huanglong (Yellow Dragon) Mountain reserve and World Heritage Site is the 3.6 km-long travertine formations. These consist of over 3,000 brightly colored pools cascading over travertine terraces, rapids and waterfalls. Caves also extend beneath the valley. The intense colours of the pools which vary between blue, green, yellow and milky are caused by the high calcium bicarbonate content of the water.
