Is netleaf hackberry a viable rehabilitation species for Idaho rangelands?

Netleaf hackberry's (Celtis reticulata) fragmented distribution in Idaho appears to be controlled by a variety of factors. Hackberry is generally restricted to semi-arid portions of the state where temperatures are least severe during the winter months, such as in moderated river canyons and at elevations below 1,500 m. Hackberry occurs in a variety of habitats, however, it is most abundant on sites with a southeast to southwesterly aspect and a rockey surface cover. Although seeds have low germination rates and individuals are often slow-growing, the variable site conditions which hackberry tolerates, in addition to its other positive attributes (i.e. landscape structure, wildlife food and cover, resprouting potential), are favorable qualities for rehabilitation species. While experimental study plots are needed to test the species' ultimate suitability for rangeland rehabilitation in Idaho, some general planting recommendations can be made based on the results of this research combined with field observations.
