It has been widely recognised that the participation of different groups of people is crucial to urban forest management. This paper aimed to focus on the motivating factors and conditions that foster participation in urban forest management. Also, the main constraints which limit participation were explored. Therefore, a survey using a researcher-designed questionnaire was used to gain information from forest visitors. Exploratory factor analysis was used to categorise all the effective factors and constraints into summarised factors. Using a principal component analysis, it was found that the most important factors encouraging participation in urban forestry were health and environment improvement and involvement spirit. These two factors explained about 60% of citizens' participation variance. The constraints also were categorized into four categories namely "lack of legal support", "lack of cooperation spirit", "lack of motivation" and "lack of time and awareness". The stepwise regression model with socio-economic features and factors affecting citizens' participation in forest management also showed that five variables, namely health and environment improvement, having a child, involvement spirit, lack of motivation and income were predicting 45.1% of the effective factors on citizens' participation. The results suggest that to enable more participation of citizens, the legislative structure should change and institutional support increase. In addition, motivation, particularly economic and increasing awareness are necessary for attracting citizens to participate in forest management plans.
