Birds in ChinaNatural reserves and forests in China have suffered from widespread logging and degradation, as well as a great hunting pressure, but many areas are still immensely rich in vegetation and wildlife.In recent decades, the Chinese government has protected hundreds of new areas and established bans on logging; as a result it provided a great opportunity to ensure the long term survival of the unique biodiversity of the country.

Asia, birds paradiseThanks to the diversity of habitats, Asia is home to more than a quarter of the worlds species.It has 2,700 bird species, a quarter of which are protected species and an eighth are globally threatened species.In Asia there is a total of 2,293 IBAs (important bird area) in 28 countries, covering a total of 2,331,560 km2 , equivalent to 7.6 % of the worlds land .

Importance of birds to other speciesBirds are known to be good indicators of the biodiversity of an area. Studies have shown its effectiveness in supporting other species.Analysis by IBA networks show that birds protection would be an important contribution to other plants and animals, especially in areas where there is not a large biodiversity. Thesis proposalThe initial research of the area shows clearly the importance of birds in the area. Xixi wetland is also called the bird paradise and is considered an important place in the migratory routes of birds.The placement of the intervention is located in the area with most biodiversity determined by the Ramsar treaty. In the north of this zone three areas of research surrounding the selected space are delimited.

The main followed strategies are: - Integration of the environment surroundings in the intervention: orientation of volumes to different interesting areas for research, optimizing this strategy - Usage of local materials such as bamboo - Inclusion of Water into the project - Positioning adapted to the climate, creating a natural air flow caused by pressure, helping to eliminate moisture - Absolute respect for the wetland, creating a floating project that requires minimal foundations - Isolated intervention but well communicated through existing land routes or routes through the channels

Construction strategies:The intervention is designed in such a way that the construction is fast, the system used aims the visitors and workers to relate with the environment through the building, using a bamboo structure that will be visible at all moments. Enclosure walling is separated from the bamboo structure, forming boxes of rapid assembly due to its dry joints; By separating the structure from the enclosure walling a natural air circulation is achieved. There will be 3 typologies, the first two have the roof in common, which is designed creating different topographies mimicking the bird wings creating a natural ventilation that will help to eliminate the humidity of the environment. On the third one an aviary is introduced inside the building adapting it to the enclosure walling of the lower level and creating a spaces where the researchers can breed endangered birds or take care of hurt ones until they can be freed. In such to create spaces for the tourists or researches to relax while watching how the birds interact. The communication between volumes is through gateways with articulated joints that absorb the differential movement between platforms. The staircase will be placed on the service platforms becoming an important element, growing over the water to create a greater connection with the environment.

Plan distribution:After a thorough investigation on the needs that these centers may have, 4 areas were created; always ensuring sustainable intervention. Each area will include 2 or 3 volumes of served spaces and another one focused on serving spaces and circulations. The 4 areas are: - Veterinarian area_ where the staff will take care of injured animals that may be found - Laboratory area_ where research is conducted and samples of birds and of vegetation will be analyzed in order to obtain the necessary data without needing to be dependent of another centre - Housing area_ this area will be used by the center researchers and external investigators that are performing a temporary study. Thus the workers will be wrapped by the environment - Tourist area_ this is an alternative source of income for the projects, and it contributes to create an economically sustainable complex. From here there will be a tour to see how the center works and to promote the ornithological tourism

StructureThe pile caps are of a reduced size in order to create the least impact on the surroundings. The intervention starts in the period of time when the water level decreases by 2 meters. Sheet piles are placed limiting the area in order to dry it to create the working space. These foundations are joined to steel pillars that will be responsible for guiding the building accompanying the change in water level , then the wetland is allowed to recover their land and the buoyant platforms are made from the shore with the patent: Coastal Engineering - Amphibious housing.The next step is to assembly the bamboo structure; given that the joints are screwed, it is a rapid and efficient process.

MEPAs sustainable strategies for the facilities it can be highlighted the use of temperature of the wetland water for cooling/heating and the storage of rain water through the Chinese rain chains. The rain water will be stored in deposits which connection will assume 2 m of water level change. There will also be a treatment area for used water using macrophytes plants before returning to the wetland.The roof will help to create privacy or areas for birdwatching thanks to the inclination, creating a structure that resembles the wings of birds with different topographies and densities of materials so that space between different buildings is covered creating shade areas whilst favouring the air circulation to prevent moisture.

ConclusionThe result is a community of small architectures without a main faade, where unexpected elements are combined. It is a structure that mingles with nature in a respectful way, altering as little as possible the existing area and adapting to the natural changes. A place to protect nature and encourage the study of birds behaviour.
