The major types of seed tree systems can be differentiated based on
the arrangement of the seed trees.
In uniform seed tree systems, individual trees are more or less uniformly distributed throughout the block. This system is the most common seed tree system in BC. Often more trees are left than the number required to meet regeneration requirements. This provides an economic opportunity for a removal cut or can satisfy other resource objectives, such as wildlife habitat. |

|
In a grouped seed tree system, seed trees are left in the block in small patches. These patches may be arranged in irregular groups or in strips. Generally, seedfall distance is a major consideration for determining distances between patches or groups of seed trees, although non-timber objectives may also play a part. |

The size of the seed group has of course great influence in determining its windfirmness. |
