A pollinator-friendly and ecologically sustainable garden is both beautiful and able to attract and sustain beneficial insects, reducing the need for pesticides. This publication is based on new research in habitat management for purposes of planting insect-attracting plant species in order to intentionally draw insects to garden areas and urban landscapes. This is done by providing a refuge for the insects during winter and nectar and pollen resources. Plant selection directly affects beneficial insect populations, those insects that can provide ecological benefits such as biodiversity and natural pest control. This concept of “habitat management” can lead to potential increases in pollinating and other beneficial insect populations. An increase in these populations in landscapes will contribute to improved pollination of plants and biological pest control and reduce the need for pesticides.
