Social-ecological filters influence plant and invertebrate diversity in educational gardens in a South American metropolis

Urban Farm DB summary

A study analyzed plant and invertebrate species richness and influencing social-ecological filters in 33 vegetable gardens in municipal schools within the Metropolitan Area of Santiago (MAS), Chile. A total of 362 plant species and 127 invertebrate morphospecies were recorded. The most influential social-ecological filters for plant richness were garden area, percentage of cultivated ground cover, and summer irrigation. For invertebrate richness, the most influential factors were plant species richness, bare ground cover (with a negative effect), and to a lesser extent, tree cover in the garden's buffer zone and summer irrigation.
