These are preferred by most wildlife because they are higher in fat than the other categories. Fat provides twice the energy compared to sugar. Examples of these fruits are dogwood, magnolia, sassafras and black gum. Different from the fall high quality fruits, fall low quality fruits still have about 70 percent of their fruits remaining until January 1. These fruits are low in sugar and low in fat, so they're not as popular.
Examples are sumac, poison ivy, bayberry and juniper.
Indeed they have. Every year locals get confused by trees changing leaf color long before fall foliage season. Poison ivy, sumac and dogwood, as well as other species, exhibit early leaf change. If you're looking to bring more wildlife into your yard, give them fruit. You don't have to plant, though.
