In this study, a questionnaire survey in Kyoto City revealed the awareness and tolerance of local residents as the value consciousness of Spodiopsar cineraceus colonies formed on street trees. As a result, many people realized that they could not tolerate the colony. As a point they can't stand, they were concerned about hygiene caused by excrement. Colony perception was also thought to be influenced by the presence or absence of actual harm. On the other hand, it was thought that few people would like to take measures to eliminate the colony. Those who admitted to being able to put up with the colonies and those who didn't want to be driven away by countermeasures thought that the pruning of street trees should not be rigorous. Therefore, it was thought that existing measures and pruning of street trees were not necessarily the consensus of local residents. This is supported by the fact that many people called for coexistence with starlings. Then, from the covariance structure analysis, it was shown that the resistance of the colony is increased by increasing the value consciousness of animals and plants and the value consciousness of street trees. Therefore, in order to create a city with a view to coexisting with Spodiopsar cineraceus, it is necessary to foster a value consciousness for animals and plants and a sense of value for street trees.
