A light tree species or light wood species is a name for tree species which, contrary to the shade tree species, require a certain minimum of light to grow and usually show very rapid initial growth . In the context of management and forest care, light tree species must rather be exempted. In addition to light, water and the type of soil are other limiting factors. The light trees include the types of oak , alder , larch , poplar , pine , willow and birch .

Individual species with a special need for light are silver birch ( Betula pendula ), downy birch ( Betula pubescens ), European larch ( Larix decidua ), mountain pine ( Pinus mugo ), black pine ( Pinus nigra ), Scots pine ( Pinus sylvestris ), white poplar ( Populus alba ), black poplar ( Populus nigra ), aspen ( Populus tremula ), downy oak ( Quercus pubescens ), English oak ( Quercus robur ), willow ( Salix alba ), sal willow ( Salix caprea ), broken willow ( Salix fragilis ), as well as crab apple and juniper .

The so-called minimum light enjoyment is 1/5 to 1/10 of the outside light and is necessary in order to be able to thrive. The European larch and the silver birch have the greatest need for light among forest trees .
