Two trees of the same species and size, bought from two different nurseries, are often very different. The differences are likely to affect the health of the tree and the benefits that tree provides to the community. Getting the best trees will improve the health of the urban forest and reduce the cost of the maintenance program. Unfortunately, communities are still making poor choices. The low bidder offers the best deal only when he supplies a product of the same quality as that of the higher bidder.
Most communities request trees based on species and size only.
Although these are important specifications, they are no more important than other factors that need to be outlined in the bidding prospectus. Scientists are working with nurseries to research and develop genetically superior trees, and each year more improved trees become available. Communities need to keep track of these improved cultivars and add them to their lists of trees for purchase. Genetically improved trees are one of many elements to consider when selecting a quality tree. Your next consideration should be how the nurseries plant, cultivate and maintain their trees.
