A reforestation and nourishing practice by the use of a lighter-than-air airship system, for dispersing and planting tree saplings, primarily in remote regions which may have been devastated by fire, where access to such regions by personnel and ground equipment is difficult. The airship system comprises an aerodynamically configured structure having a semi-rigid keel or skeleton, where lift is provided by helium, with the keel mounting a liquid management mechanism consisting of a reservoir open to the outside for resupply of liquid or water, a conduit leading to a holding tank, and a piping distribution and nozzle assembly below the airship system to spray or dispense the liquid or water over selected areas to water or nourish the newly planted trees. The mechanism for temporarily storing and eventually dispensing the tree saplings is a rack mounting at least one cylindrical canister containing plural compartments. The cylindrical canister includes a sliding cover that is operable to open and close one compartment to allow stowage and release of the tree saplings.

1. A lighter-than-air airship system for distributing and planting tree saplings while in a flight mode over defined ground areas, where lift for said airship system is achieved by means of helium confined therewithin, said airship system comprising: a.) a semi rigid, light-weight frame encased within a flexible skin and aerodynamically configured for flying and hovering over selected ground areas; b.) means for flying said airship system, where said means include a plurality of engines and attitude stabilizing mechanisms to provide 3-axis stability and control; c.) an undercarriage frame suspended from said airship system, said undercarriage frame mounting at least one horizontally disposed canister, said canister including i.) an intermittantly rotating axle, ii.) plural axial vanes extending from said axle to define plural compartments for receiving said tree saplings, iii.) a fixed peripheral, circular cover about said compartments having two axially extending slots, iv.) a discontinuous, generally circular sliding cover about said vanes and movable between said said slots, and v.) a means to rotate said axle relative to said sliding cover to open selective said compartments to store and release the tree saplings contained therewithin; and d.) a liquid control and dispensing mechanism in proximity to said undercarriage frame to supply liquid to the defined ground areas. 2. The lighter-than-air airship system according to claim 1, wherein said liquid control and dispensing mechanism comprises: a.) a liquid holding tank positioned along the center of gravity of said airship system, b.) a manifold in liquid communication with said holding tank, where said manifold includes means for controlling the quantity of liquid passing therethrough, and c.) a liquid distribution, piping and nozzle assembly in liquid communication with said manifold. 3. The lighter-than-air airship system according to claim 2, wherein said liquid control and dispensing mechanism further includes a reservoir, open to the exterior of said airship system, for receiving in-flight replenishing of liquid, to feed liquid to said holding tank. 4. The lighter-than-air airship system according to claim 3, including a liquid passing conduit extending between said reservoir and said holding tank, and said conduit includes a series of baffle elements to minimize turbulence in the liquid passing therethrough. 5. The lighter-than-air airship system according to claim 4, including a first debris collecting filtering screen within said reservoir, a second filtering screen between said reservoir and said liquid passing conduit, and a third filtering screen between said holding tank and said manifold. 6. The lighter-than-air airship system according to claim 3, wherein said reservoir is defined by an opening and a predetermined depth, and said opening includes a criss-cross grating member. 7. The lighter-than-air airship system according to claim 1, wherein said means for flying includes a pilot's cabin of a size to receive operating personnel. 8. The lighter-than-air airship system according to claim 1, wherein said canister is essentially cylindrical in shape, and further includes a pair of end walls having bearing assemblies axially extending therefrom. 9. The lighter-than-air airship system according to claim 8, wherein said compartments further are divided by plural transverse partitions. 10. The lighter-than-air airship system according to claim 1, wherein the combined radial extent of said fixed peripheral cover and said sliding cover are less than 360°.
