  • Publication number: 20080098647
    Abstract: A method of operating equipment around trees. The method includes the steps of: providing a plurality of modules; joining the plurality of modules to each other in an operative state at a site wherein the plurality of modules are placed against a ground surface over roots of at least one adjacent tree so that water can be directed at least one of (a) through at least one of the joined modules and (b) between the joined modules to be directed against, and evaporated from, the ground surface; moving equipment against the plurality of joined modules so that weight forces for the equipment are distributed through the plurality of modules over a substantial area of the ground surface to avoid application of concentrated forces that may inflict damage to the tree roots; and removing the plurality of modules from the site after moving the equipment against the plurality of joined modules.
