Acacia, False Aacacia and Platanus Acerifolia were three main kinds of street trees planted in Qingdao before the WWII. All of these three kinds of trees were imported to Qingdao from Germany by the German governors since 1898. By doing this, the street landscape in Berlin was reproduced in its colony Qingdao. It turned out that rather than planting trees of their own countries, Acacia, False Aacacia and Platanus Acerifolia were continuously planted in the new areas of Qingdao by Japan and the Republic of China government later. The reason why the continuity of street landscape was well kept is probably because that the street trees were considered as quite important links between the new and old town. However, due to the political reasons, there were no street trees planted in the area where Chinese lived. This problem had not been solved until Qingdao was recovered by the Republic of China government. Nowadays, Cedar is increasingly planted in Qingdao's street and a new feature of street landscape is being created in the city.
