Giergiczny and Kronenberg (2014) present a choice experiment to value street trees in the city center of Lodz,
Poland, and the broader context of how valuation results helped one to improve the governance of UES in this city.
Based on a simplified inventory of trees in the very center of the city, the authors prepared a set of hypothetical
programs, assuming changes in the length of three different categories of streets. Different programs put varying
emphasis on different ways to increase the numbers of trees, along with different levels of a hypothetical tax that
would have to be paid by respondents to implement a given program. The study indicated that the 400 surveyed Lodz
residents were willing to pay the highest price for greening those streets where currently there are few or no trees. In
general, people were willing to pay for planting trees in the city center. This is an important argument in the public
debate not only on the new development strategy for the city but also for the broader context of governing UES in
Poland.
