Forest succession most relevant to forestry originates following forest harvesting or wildfire. That following harvesting is most often also influenced by site preparation procedures for reforestation. The resultant vegetation succession is dependent on the type, degree, and timing of the disturbance, the site characteristics and conditions, and the microclimate. Subsurface organs, including roots, rhizomes, and stumps, allow most species of shrubs occurring on moist and wet forest sites to survive burning and crushing. Establishment and survival of some forbs, such as fireweed and bracken fern, are greatly facilitated by burning. Effective non-chemical techniques for providing desirable forest tree species a successional advantage over competing forest species are discussed. These involve different silvicultural systems, time of logging, type of scarification, time and degree of burning, time of planting, size of seedlings, and other reforestation considerations.

Background: Previous descriptions of the insertion site of the posterior cruciate ligament are inadequate. Hypothesis: More than one reference system is required to adequately represent the anatomy of the femoral attachment. Study Design: Descriptive anatomic study. Methods: Twelve cadaveric specimens were evaluated by using two measurement methods relative to the femoral articular cartilage margin and two methods relative to the intercondylar femoral roof. Results: Reference lines perpendicular to the articular cartilage best defined the 12- and 1-o'clock positions, and those perpendicular to the articular cartilage or parallel to the femoral shaft best defined the 2-, 3-, and 4-o'clock positions. The angle of the proximal attachment to the roof was 88° ± 5.5°. The posterior cruciate ligament was a continuum of fibers rather than two distinct bundles, and its attachment showed variability in shape and thickness, extending past the midline in the notch (11:21 ± 15 minutes to 4:12 ± 20 minutes, right knee). Conclusions: More than one measurement system is required to accurately describe the femoral origin of the posterior cruciate ligament. Clinical Relevance: Accurate assessment of the anatomy is crucial for successful surgical reconstruction of the posterior cruciate ligament femoral attachment.
