It is very important in sustainable agriculture to keep and create natural refuges and buffers that can act as insectaries for not only a wide range of bees, butterflies, parasitic wasps and predatory insects but also for a whole host of other native mammals, birds, reptiles and amphibians.
If within the Southern Interior of B.C. protect and encourage growth of native plants such as sagebrush, rabbitbrush, various buckwheats, wild rose, snowberry, sumac and goldenrod.
