How do urban gardens contribute toward maintaining biodiversity? A group of Portland State University and Oregon State University researchers, teachers and neighbors in different Portland communities have been collecting data in yards and community gardens in Portland. Among our findings are that the tree canopy has a big influence on the arthropods available for birds to eat, and on the diversity of birds. Also, there is a large diversity of native bees in Portland gardens.
By collecting data on the bees and other pollinators, birds, arthropods (insects, spiders and other invertebrates) that birds eat and the vegetation in gardens, we can understand how we might better support urban biodiversity.
