Agroforestry
Agroforestry is the combination of shrubs and trees with field crops or pasture for their mutual benefit in order to create a land use system that is more diverse, sustainable and more productive.

Forage/fodder
Plants that are suitable for feeding pasture animals.

Quick canopy
Fast growing trees that are usually pioneer species and often short-lived that can be planted to form a closed canopy after only a few years to afford protection to plants that are slower to establish and more tender when young.

Green manure
Plants that can be planted as a cover crop and tilled under to improve soil fertility, before their seeds get ripe.

Nitrogen fixing
Many legumes (Fabaceae) grow root nodules that are inhabited by bacteria which can fix nitrogen directly from the air. Nitrogen is an essential nutrient required for plant growth and the bacteria enable the plants to grow on poor soils. Some of the nitrogen is not used up by the plant itself and benefits other plants that grow close by.

Forestry
Large or at least medium-sized trees that are usually fast growing, produce a good quality wood, and are adaptable to forestry planting and processing techniques.

Windbreak
Wind resistant and mostly fast growing shrubs or trees that are ideally suited for planting windbreaks.

Erosion control
Trees, shrubs or perennials with a dense network of roots that are ideally suited to fight erosion problems in loose soils.

Fire resistant
Plants that are adapted to surviving occasional fires, either by being able to resprout from underground organs or by possessing a bark or fibrous covering structure of the trunk that protects the growth organs of the plant from overheating.
