Learning about restoration of urban ecosystems: a case study integrating public participation, stormwater management, and ecological research

Abstract

Restoration of ecosystem functions in urban environments is made challenging by 1) a public that often lacks understanding of ecological principles, 2) inadequate evidence of the effectiveness of restoration practices, and 3) difficulty integrating social and biophysical factors in studies of urban ecosystems. This paper describes a case study in which potential solutions to these challenges were explored. We facilitated collaborative learning through public participation in the design and implementation of an urban riparian buffer along a headwater stream in a neighborhood park, a process that was informed by ecological research. Learning outcomes were evaluated using surveys and qualitative assessment of discussion. Results indicated that participants' knowledge about water quality problems associated with urbanization, stormwater, and nonpoint-source pollution increased, familiarity with stormwater management practices increased, and perceptions about the importance of stream ecosystem functions changed. In-stream monitoring of sediment delivery, as well as direct measurements of buffer infiltration capacity, provided early evidence of buffer effectiveness in prevention of sediment inputs to the stream and absorption of runoff from surrounding surfaces. This study provides a useful model for integration of collaborative learning through participation, ecological restoration, and ecological research in an urban setting. Elements deemed essential to success of this model included an opportunity for dialog focused on a specific natural feature, sustained interaction between participants and researchers, opportunities for hands-on participation by urban residents, and flexibility in restoration practice installation.

Characterisation of Nature-Based Solutions for the Built Environment

“…Communities have been focal points since early attempts to address urban issues using nature-based solutions [21,22,24]. Over the past decade there has been a rapid increase in the number of Citizen Science initiatives which offers an attractive solution for on-going monitoring [134][135][136], and the engagement and empowerment of communities to lead urban green actions. A participatory planning process is critical in identifying and mainstreaming nature-based solutions in towns and cities.…”

Fish assemblage and habitat factors associated with the distribution of Topeka shiner (Notropis topeka) in Kansas streams

“…urban land and impoundments) are linked to the absence of Topeka shiners, conservation and rehabilitation efforts may help minimize the anthropogenic impact on Topeka shiners and other native fishes in these streams. For example, establishing riparian buffers around streams may reduce the impact of urbanization and agricultural practices on these streams (Wang et al 2001;Herringshaw et al 2010). By identifying factors associated with the presence and absence of Topeka shiner populations this study may help managers conserve current Topeka shiner populations and identify sites for future reclamation and conservation efforts.…”

Engaging the Private Homeowner: Linking Climate Change and Green Stormwater Infrastructure

“…Further motivation for this project comes from the finding that coastal risk management policies should promote private adaptation initiative by integrating it into public adaptation strategies and efforts [27]. In addition to the climate adaptation literature, examples of projects can be found that provide evidence of engaged private citizens active in public stormwater efforts [34][35][36]. Previous studies in the MLSCA identified residents of a Duluth, Minnesota neighborhood that understood the connection between excess stormwater and Lake Superior water quality [37].…”
