6-Day River & Wetland Environmental Service: Hangzhou & Chengdu

Morning - arrival
Your guide meets you at the airport or the railway station and takes you to a hotel in the city. Hangzhou sits at the head of the Qiantang estuary, and water is the organising fact of the place: the Grand Canal ends here, West Lake is maintained by hand, and the Xixi wetland on the western edge of the city is one of the largest urban wetlands in China. The morning is free.

Afternoon - orientation: what you will and will not do
The placement is arranged with the park authority or a local environmental organisation through the programme's partner in China, and the site, dates and tasks are confirmed with the group leader before departure. The orientation is practical. The work on this programme is monitoring, surveying and clean-up of a defined kind, and the briefing sets the boundaries: volunteers do not handle wildlife, do not carry out any treatment of injured animals, do not operate boats, pumps or machinery, and do not enter the water. Anything found that looks significant - an unusual bird, a dead fish, a discharge pipe, a tagged animal - is photographed, located and reported to staff, not dealt with. The safety component covers the specific risks of the site: soft banks that collapse, mud, insects, summer heat and humidity, thunderstorm weather in the afternoons, and the boats and anglers who share the water. Life jackets are worn where the site requires them, nobody works alone, and anyone who cannot swim stays on the boardwalk.

Late afternoon - methods and data discipline
The rest of the afternoon is training on the instruments and the record sheets, because the value of citizen monitoring depends entirely on doing it consistently. Volunteers learn the fixed sampling points, the depth at which a sample is taken, how to rinse a bottle, how to read a test kit for dissolved oxygen, pH, turbidity and ammonia nitrogen, and how to log a GPS point and a time. The rule that matters is that a measurement you are unsure of is recorded as uncertain rather than guessed, and that missing data is left missing. Everything recorded goes into the partner's spreadsheet at the end of the day, not into a private notebook.

Evening - dinner and a first look at the lake
Dinner in the city, then a walk on the West Lake shore. It is worth seeing the contrast between the two waters you will be working with - the managed, landscaped lake in the centre, where every island and causeway was placed by somebody, and the reed beds and channels of the wetland on the edge of the city - because the comparison is part of what the monitoring shows. Your guide will point out where the lake is fed and where it drains, and how much of the shoreline is now hard-edged; the answers explain why the wetland on the western edge is protected rather than built on, and why the readings you take tomorrow at fixed points are compared against a record rather than interpreted one at a time. The evening ends early, and the group is asked to bring closed shoes, long trousers, a hat and a rain jacket for the wetland day regardless of the forecast.

Cultural Insight - why the wetland is protected
China's Wetland Protection Law, in force since 2022, gives legal protection to wetland areas and requires a register of the most important sites; Xixi was among the first national wetland parks and its channels, ponds and mulberry banks are a surviving piece of the low-lying water landscape that once surrounded Hangzhou. Urban wetlands of this kind do four things that are hard to price: they store floodwater, they strip nutrients out of water that would otherwise reach the lake, they support a bird population on the East Asian-Australasian Flyway, and they cool the city around them. The monitoring brief on this programme is designed around that list.

Morning - sampling at the fixed points
You enter the park before the visitor crowds arrive, with park staff, and work the same sample points they use. The routine is unglamorous and that is the point: the same point, the same depth, the same kit, the same record sheet, each time the group comes. Over a morning the group can cover a set of points across the main channels, and the staff will show the group's numbers against the park's own recent records, which makes the exercise real - a dissolved-oxygen reading at the end of a hot night with no wind looks very different from one after rain. Photographs of the sample point and the water colour are taken every time, because they are the cheapest way to explain an odd number later.

Late morning - vegetation and birds
The second task is a survey along the boardwalk, counting and mapping rather than collecting. The park staff will identify the target species and, more importantly, the problem species: water hyacinth, alligator weed and several others are invasive in these waters, and their spread is monitored and managed. Volunteers record presence, extent and location on a simple map and, where the park asks for it and supervises it, remove by hand what can safely be pulled from the bank and piled for collection. Anything beyond the reach of a rake is left alone and reported.

Afternoon - a supervised clean-up and the tally
After lunch the group runs a litter survey on one section of bank or boardwalk, using a fixed route and counting by category rather than simply bagging everything: drink containers, plastic bags, fishing line, packaging, cigarette ends. Recording what is found, and where, is more useful to the park than the volume removed, because it points to where a bin, a sign or an enforcement patrol is needed. Gloves are worn throughout, glass and sharp metal are picked up with tongs and never by hand, and the bagged material is handed to the park's own collection point. Wetland clean-ups are not the place for heroics; two hours of systematic work beats a whole day of scrambling.

Evening - data entry and reflection
Back in the city, the group enters the day's readings and observations into the partner's spreadsheet and compares them with the previous day. The reflection session is short and technical: what was measured, what was uncertain, what needs repeating. The point of reviewing it on the same evening is that a number nobody can explain is worse than no number at all - if the oxygen reading at one point looks wrong, the group decides whether to re-sample it in the morning or to record it as an outlier with a note. Any damage to kit, any litter that could not be collected, any incident on site and any wildlife seen in distress is reported to the coordinator the same day, with the location, and the partner decides what to do about it. Photographs from the day are labelled with the sample point and the time before anyone goes to bed, because that is the record the park actually uses.

Cultural Insight - what citizen monitoring is for
Environmental agencies cannot sample everywhere as often as they would like, and a consistent, well-documented set of readings from the same points has genuine value: it fills in gaps between official surveys and it establishes what is normal for a stretch of water. Its limits matter too, and the training is explicit about them - hand-held kits are indicative rather than laboratory-grade, a week of readings proves nothing, and the point of the exercise is the method and the record, not a conclusion. That is why the data goes to the partner and is used, or not, by them.

Morning — West Lake Cruise
Begin with a boat cruise on West Lake, a UNESCO World Heritage Site and Hangzhou's crown jewel. Glide past Leifeng Pagoda and the tree-lined Su Causeway, framed by willows and lotus, while your guide shares the legend of the White Snake. The lake has inspired Chinese poets and painters for a millennium.

Afternoon — Lingyin Temple
Visit Lingyin Temple (“Temple of the Soul's Retreat”), one of China's oldest Buddhist monasteries, founded in the 4th century at the foot of Feilai Peak. Marvel at its grand halls and the 1,700-year-old laughing Buddha, then explore the Feilai Feng Grottoes with their intricate rock-carved Buddhist sculptures.

Evening — West Lake Music Fountain
End the day at the West Lake Music Fountain near Hubin Park, a free choreographed display of water, light, and music. Arrive early for a front-row view of this blend of tradition and modernity.

Morning - south-west to the Chengdu plain
The flight from Hangzhou to Chengdu takes about two and a half hours and crosses the whole width of southern China, from the flat delta to the Sichuan basin, which is a bowl of fertile land ringed by mountains and permanently damp. Chengdu's river is the Jinjiang, formed in the city by the junction of the Fu'nan and Nan rivers, and both are part of an irrigation system that has been running since the third century BC. That matters for the monitoring: the water in the city is not a wild river but the tail of a managed system, and its temperature, flow and chemistry reflect what happens on the plain upstream.

Late morning - the working stretch
The placement is arranged with a local environmental or community organisation, and the stretch of river you work is agreed with them in advance - usually a public reach with a promenade, used for walking, fishing and, in summer, by people sitting on the bank. The morning is the standard routine: sampling at fixed points, readings logged, water and bank photographed, notable observations recorded. Urban rivers carry specific signals - foam below a weir, grey plumes after rain, sewage smell in still water in summer - and the coordinator will explain what the partner is watching for and what should be reported rather than tested by volunteers.

Afternoon - clean-up and outreach
After lunch the group works the bank: a fixed route, litter counted by category, bagged and taken to the city's own bins or handed to the partner's collection point. Gloves and tongs throughout, no wading, no reaching into the water, and no moving anything heavy without help. The outreach part is the more useful half. Chengdu has run household waste-sorting campaigns for years, and a short session with residents - what goes in which bin, what happens to a plastic bottle after it is collected, why fishing line on the bank is a hazard to birds - is welcomed more often than volunteers expect. A board or a printed card in Chinese, prepared the night before with the partner's help, is more effective than a conversation in English.

Evening - data and reflection
The day's numbers are entered into the partner's sheet, with the sample points, the times and the weather noted alongside them, and any point that looked odd is flagged for a repeat rather than adjusted. The first two days of readings now exist as a usable set, and the group is asked what it can and cannot say from them: not that the river is clean or dirty, but that these points read like this, on these two days, in these conditions, which is the honest version. Anything the group saw but could not measure - a smell, a discharge, an unusual number of dead fish, a stretch with no bank vegetation - is written up as an observation with a location and a photograph and passed to the partner, because observations of that kind are often what an organisation can act on. The reflection closes with the two-city comparison: a landscaped urban wetland and a working river are managed for different purposes, and the monitoring reflects that. Dinner is Sichuan, and the group should expect it to be genuinely spicy.

Cultural Insight - the oldest irrigation system still in use
The Jinjiang sits at the end of the Dujiangyan system, built around 256 BC by the Qin governor Li Bing and his son, which divides the Min river without a dam, using a levee, a spillway and a channel cut through rock to deliver water to the Chengdu plain while letting floodwater and silt pass. It still irrigates the plain and it was inscribed by UNESCO in 2000 as a cultural property. Chinese river management has a second, very current layer: the river-chief system introduced nationwide in 2016, in which a named official is responsible for a named stretch of water, with a phone number on a sign at the bank. Your sampling points sit inside that system, and the partner organisation will tell you who the local river chief is and how a report reaches them.

Morning - two sites, one river
The final working morning applies the week's method to a comparison. Depending on what the partner has agreed, the group samples at two or three points that sit in different conditions - above and below a weir or a treated discharge, inside a park wetland and on the open channel, or at the inlet and outlet of a constructed wetland that the city uses to polish stormwater. The reading of the results is the work: temperature, oxygen, turbidity and nutrient readings plotted against each other, alongside the time, the weather and the photographs. Volunteers are asked to state what the numbers do not show as clearly as what they do, and the partner's staff check every claimed conclusion before it is presented.

Late morning - compiling the record
Then the group builds the deliverable the partner actually wants, which is usually short and simple: a spreadsheet of all readings with the sample-point metadata, a folder of labelled photographs, a one-page summary in English and Chinese of what was observed at each site, and a list of anything that should be re-checked by staff. Nothing is published anywhere, on any platform, without the partner organisation's written agreement, and unpublished observations - a location of a bird nest, say, or a bank that is eroding - are treated as confidential in the same way the partner treats them.

Afternoon - presentation and handover
The group presents the week to the partner organisation: what was sampled, what the readings looked like, what was uncertain, what failed, and what the partner would need if they wanted a group to do the same again. The staff are asked directly what was not useful. This is also the point at which volunteers hear, usually for the first time, how a single week of visitor data fits into an organisation's year - and it is rarely by producing a finding, but by providing a small amount of labour the staff would otherwise have had to do themselves, and by leaving a record that can be continued.

Evening - closing seminar
The final session is a discussion rather than a summary, and it is built around three questions: what the week measured, what it did not measure, and what a group of eight visitors can and cannot claim about a river they have known for four days. Participants are asked to consider the alternative uses of the same money - funding a local monitoring programme, for example - and to say honestly whether the placement was worth the carbon and the cost. The record of participation, where the partner issues one, is handed over here.

Morning — Dujiangyan Irrigation System
Discover the Dujiangyan Irrigation System, a 2,200-year-old UNESCO World Heritage Site built to tame the Min River. Its ingenious channels, embankments, and spillways, made with nothing more than bamboo, stones, and skilled labor, still control flooding and water the fields of the Sichuan plain. Walk across the Anlan Cable Bridge to appreciate the scale of this enduring engineering marvel.

Afternoon — Qingcheng Mountain
Hike Qingcheng Mountain, a Taoist sanctuary shrouded in misty forests and long revered as a birthplace of Taoism. Visit the Tianshi Cave, associated with the origins of the Taoist tradition, and savor Taoist vegetarian dishes at a hillside temple. The serene paths and forested slopes make an ideal setting for quiet reflection.
