A new report out from Agrologist Tim Ross on long term effects of ER treatments on understory vegetation in ponderosa pine open forests.
This project has demonstrated that populations of understory vegetation are light dependent, but has also confirmed that available light is not the only controlling factor. Soil type is a contributing factor, as soils developed under either grassland conditions, forest conditions or at the grassland/forest interface. The release of understory vegetation, in particular bunchgrasses, is largely dependent on the pre-treatment composition of the plant community.
