Is there a relationship between socioeconomic level, vegetation cover, free-roaming cats and dogs, and the diversity of native birds? A study in a Latin American capital city
Abstract
Understanding how social and environmental factors influence biodiversity can contribute to sustainable development and promote environmental justice in cities. This knowledge is especially important in developing countries with strong social and environmental inequalities. This study investigates native bird diversity in relation to the socioeconomic level of neighborhoods, their plant cover, and the abundance of free-roaming cats and dogs in a Latin American city. Two causal hypotheses were tested: 1) socioeconomic level (defined by education and income) influence native bird diversity indirectly, as an effect mediated by plant cover, as well as directly; 2) in addition, socioeconomic conditions also influence free-roaming cats and dogs which could affect native bird diversity. To test these hypotheses, data were collected at 120 sites located in neighborhoods of different socioeconomic levels across the city of Santiago de Chile and fit to Structural Equation Models. Evidence supported the second hypothesis: in wealthier neighborhoods there was greater plant cover that, in turn, positively influenced native bird diversity; in addition, fewer free-roaming cats and dogs were found in these neighborhoods but they had no effect on native bird diversity. Results suggest that increasing plant cover, especially in more socioeconomically vulnerable neighborhoods, would contribute to urban environmental justice and more equitable opportunities to access native bird diversity.
