Hall reported that in the Blue Mountains of Oregon, forests that have been maintained as ponderosa pine/pinegrass by periodic underburning (50% crown cover) produce to pounds of pinegrass per acre ( kg/ha). A common, but largely untested, strategy for maintaining forest biodiversity is to enhance stand structural complexity. A silvicultural experiment was implemented from to at Blacks Mountain Experimental Forest, California, to test the efficacy of two levels of structural diversity (high versus low) and two levels of prescribed underburning (burn versus no burn) for maintaining or Cited by: 7. Effects of selection harvest and prescribed fire on the soil nitrogen status of ponderosa pine forests Prescribed burning and productivity in southern pine forests: a review Increasing weight of evidence that thinning and burning treatments help restore understory plant communities in ponderosa pine forests. Much of our knowledge of forest growth and productivity rests on empirical trials with a known and predictable climate. Sustained productivity hinges on healthy forests and the soils beneath them in the future, when management practices and climatic controls may be different than they have been in the past. We need to know how forests and soils respond to changing conditions.

Prescribed burning in south‐western ponderosa pine forests can increase soil nutrient availability (Covington & Sackett, ; Kaye & Hart, ). Heterotrophic microbes can be negatively affected by removal of organic material but autotrophic microbes may be positively affected (Neary et al., ).Cited by: The growth of ponderosa pine and associated understory vegetation was evaluated for a 6 yr period following spring underburning of surface fuels. Underburn and control (unburned) plots were paired at 15 replicate sites in pole-sized ponderosa pine forests of central Oregon.

Other research in ponderosa pine forests has also shown decreases in N availability 5–12 years following thinning plus burning in Montana (Sala et al., ) and 8–9 years following prescribed burn treatments in Central Oregon (Monleon et al., ).Cited by: Fire is a dominant ecological factor in Mediterranean-type ecosystems. Management strategies include prescribed (controlled) burning, which has been used in the management of several species, such as Pinus nigra ssp laricio var. Corsicana, a pine endemic to Corsica of great ecological and economic importance. The effects of prescribed burning on Pinus laricio have been little by:
