Stinger technology fundamentally affects the economics of re-vegetation. It can alter either or both the cost and revenue sides of the core business. Stinger-assisted planters will offer to the contractor markets greater value than their competitors can, enabling these planters to increase their market share.

This technology is faster and more efficient than substitutes, minimizing time on site. Further, by increasing the survival rate of plant starts, planters can decrease their investment in nursery stock (i.e., their need for working capital). Alternatively, their same investment in nursery stock can service more planting sites. On the revenue side, increasing the range of terrain that can be planted (including riprap, cobble and steep road cuts) the planter can bid on more work and accomplish plantings more quickly and safely than hand-planting competitors.

If contractors are interested in survivability of planting, speed, minimizing damage to the habitat, safety and cost effectiveness, our stinger technology is a standout with each of these criteria.

When planted by the stinger, a plant's roots are protected in a plastic (biodegradable) sheath, surrounded by a precise nutritional and microbial mix. They are planted deep, closer to groundwater, yielding survival rates higher than plants inserted by other means. The rotary stinger can plant at the hourly production rate of four experienced hand-planters planting 10 cubic inch containers on most terrain. However, the stinger can plant 180 cubic inch plant containers (with correspondingly higher survival rates). If the planting rates of the stinger and hand planters are compared for the 180 cubic inch containers, the rotary stinger plants at the hourly production rate of 8-10 experienced planters.

A) On the outplanting site, a long tube seedling or non-rooted cutting is inserted into the beak. The expandable stinger is then maneuvered to the planting spot, where the beak is inserted into the soil.

B) The beak is opened allowing the seedling to drop to the bottom of the
created hole.

C) While the beak is open, the stinger is lifted from the soil leaving the seedling in place.
