"Maple Leaf's primary mission is to provide top quality nursery seedlings and services for reforestation, which will help to correct the environmental concern of "desertification" in China. Maple Leaf has a 75% interest in a joint venture contract with the County of Liang Chang, Inner Mongolia, China (which holds the remaining 25% interest) to ultimately deliver 500 million seedlings per year for 50 years".
Two and a half acres is a little over 10,000 square meters of warehouse space. The contract, if expressed over this space only, would require a seedling yield of approximately 50,000/m2/year. From this, and as indicated in the release, it is plain that more greenhouses will be needed.
Considering that a full grown tree will cover, by spread of crown and roots, roughly 25 square meters of land surface (a guess), by the conract numbers cited, each year of this greenhouse's operation should allow reforestation of 1.25 X 10*10 square meters of land. That's roughly 5,000 square miles per year of reforestation, assuming zero seedling mortality. Inner Mongolia is nearly half-million square miles, and formerly held Chiina's second largest area of forest land. Now we can see why a 50 year contract and additional greenhouses are needed. TreeHuggers will wonder what kind of trees we're talking about here. Not all the same kind hopefully.
