Quick Tips for Choosing Plants:

Planting a variety of native trees, shrubs, perennials and vines increases biodiversity and gives wildlife a source for food, cover and nesting
Choose a mixture of deciduous and evergreen trees so birds and other wildlife will always be able to find shelter
Plant trees and large shrubs where they will block winter winds from the house and shade it in summer, that will save energy and lower your carbon footprint
Try your best to buy plants that were grown locally, your independent garden center will be your best bet
Think about ultimate height and width of the plant you choose, make sure it will fit the space you have for it when it's reached maturity
Plant nectar plants in groups, to attract butterflies and other beneficial insects more easily
Ask for help if you need it. Most garden centers either have a landscape designer on staff or they can give you a reference of a designer that is adept at native plant wildlife gardening. There will be upfront costs but they are small when compared to having to redo a landscape that wasn't what you really wanted
