This paper compares carbon (C) and nutrient contents in soils (Alfisols derived from andesite), forest floor and vegetation in a former fire () and an adjacent forest in the Sagehen Watershed in the Sierra Nevada Mountains of California.

When grown in well watered soil fertilized with nitrogen, phosphorus, and potassium, redcedar seedlings outgrow the seedlings of Douglas-fir (Pseudotsuga menziesii), grand fir (Abies grandis), Sitka spruce (Picea sitchensis), western hemlock, and ponderosa pine (Pinus ponderosa).

Available nitrogen, calcium, and water appear to be the most. The response of western hemlock to nitrogen fertilizer is extremely variable. It appears to vary by geographic location and stocking level.

For overstocked stands, a combination of precommercial thinning and fertilizer often gives the best response. Forest Ecology and Management 1: Litterfall, decomposition of fine fuel, calorific value of fuel and fuel reduction by controlled burning were studied in plots in pure stands of ponderosa pine, sugar pine (Pinus lambertiana), white fir (Abies concolor), and giant sequoia (Sequoiadendron giganteum) in California.

Fowells and Schubert () reported that in 1 year in an area in California, the Douglas pine squirrel (Tamiasciurus douglasii) destroyed over 50% of the sugar pine and ponderosa pine cones.

Squirrels may remove over 90% of the cone crops of white spruce (Picea glauca (Moench) Voss) in Alaska (Nienstaedt and Zasada ).5/5(1).Plonski, W.
