Population [top]


This species is abundant. It has become an “invader” in Texas grasslands and efforts to eradicate it from pasture seem to be unsuccessful (R. P. Adams pers. comm. March 2012).

Current Population Trend:Increasing
Additional data:
Continuing decline of mature individuals:No
Population severely fragmented:No

Habitat and Ecology [top]

Habitat and Ecology:This species occurs in open grassland and shrubland, sometimes associated with Juniperus pinchotii, Pinus remota, and Quercus spp.; in sandy or rocky soil on plains, on bluffs and ridges, on hillsides or along stream beds in sandy or rocky soil, commonly over limestone. The altitudinal range is (150-)600-1550 m a.s.l. The climate is continental, with warm summers and cold winters, drier with hotter summers in the south of its range.
Continuing decline in area, extent and/or quality of habitat:No
Generation Length (years):25

Use and Trade [top]

Use and Trade: In the past the wood was used by cattle ranchers for fenceposts, but metal has displaced it. The wood is now mainly used to produce 'cedarwood oil' through steam distillation. This species is not known to be in cultivation, but it may be present in a few botanic gardens.
