Abstract
Bioretention systems are widely used in green stormwater infrastructures due to their cost-effectiveness and ability to reduce surface runoff and pollutants. Vegetation plays a crucial role in these systems, and many stormwater guidelines worldwide highlight the benefits of vegetation in their design. However, it remains unclear whether the guidelines adequately consider the plant selection process and whether this process reflects the current state-of-the-art knowledge of vegetation-related impacts on system performance. This study reviewed 47 stormwater guidelines globally, with most from North America (64 %) and Australia-New Zealand (23 %), and fewer from Europe (4 %), Asia (6 %) and Africa (2 %). The key findings reveal that the highest percentage of guidelines reviewed from North America and Australia-New Zealand suggested using native species in bioretention systems (55 % and 36 %, respectively). However, these guidelines often fail to address plant functional traits and planting strategies adequately. While some guidelines include vegetation lists, these are often optional and do not prioritize functional diversity, which is critical for optimizing system functions. The study concludes that plant origin is a primary consideration in bioretention system design, despite literature not necessarily supporting its significance in influencing performance. To improve bioretention systems efficiency, guidelines must emphasize plant functional traits, diversity and effective planting strategies. Future research should evaluate species based on these criteria to enhance system outcomes.
期刊介绍:
Ecological engineering has been defined as the design of ecosystems for the mutual benefit of humans and nature. The journal is meant for ecologists who, because of their research interests or occupation, are involved in designing, monitoring, or restoring ecosystems, and can serve as a bridge between ecologists and engineers.
Specific topics covered in the journal include: habitat reconstruction; ecotechnology; synthetic ecology; bioengineering; restoration ecology; ecology conservation; ecosystem rehabilitation; stream and river restoration; reclamation ecology; non-renewable resource conservation. Descriptions of specific applications of ecological engineering are acceptable only when situated within context of adding novelty to current research and emphasizing ecosystem restoration. We do not accept purely descriptive reports on ecosystem structures (such as vegetation surveys), purely physical assessment of materials that can be used for ecological restoration, small-model studies carried out in the laboratory or greenhouse with artificial (waste)water or crop studies, or case studies on conventional wastewater treatment and eutrophication that do not offer an ecosystem restoration approach within the paper.
