The project is a good fit with Strategic Goal 1 of the FSP: To improve knowledge-based science in support of sustainability. Specifically, this project will provide knowledge and information needed to support science-based sustainable management of BC's dry forest ecosystems. The project fits under the Sustainability Program; Ecosystem structure, function and processes, and biodiversity related to forest management Theme; and Natural disturbance ecology Topic. Objectives This project will continue to assess the recovery of understory grassland and open forest vegetation following different levels of thinning and prescribed burning in overstocked stands of IDF and PP forests in the Rocky Mountain Forest District. The objective is to determine the effect of harvesting, slashing and spring burning on the composition of the understory herbaceous and shrub layer over time (understory plant succession). Both the magnitude and direction of plant community changes will be more precisely quantified with multiple years of sampling. Monitoring the short and medium-term response of plant communities to the spring 2004 prescribed burn is an important continuing objective. It is expected that plant response to the prescribed burn will peak in the 2005 growing season. Approach Restoration of two ingrown forests was carried out using a prescription of commercial thinning and slashing in 1999 and 2000. Two sites were selected for study (2 blocks of IDFdm2; 3 blocks of PPdh2). Sampling for understory herbaceous and shrub cover, understory light, duff and fine fuel, and forage production were completed prior to harvesting (Powell et al. 1999). Timber cruise data using the same plot centres is available to describe pre-harvest stand characteristics such as basal area, density and volume. Post-harvest, short-term data from the sites were collected, analyzed and published by Page 2002. The PP site was subjected to prescribed burn in spring 2004.
