Biomass estimation for four common grass species in northern Arizona ponderosa pine
Vegetation allometric relations were examined for 4 important grass species in southwestern ponderosa pine (Pinus ponderosa). Logarithmic regressions were developed relating aboveground biomass to basal area, height, and number of seedheads, as well…

The care and feeding of increment borers
Agee, Huff
An increment borer is a precision instrument specially designed to extract a thin cylinder of wood from a tree, shrub, log or pole. It is available in a variety of sizes ranging in length from 4 inches to 40 inches. Although the increment borer is…

Effect of periodic burning on soil nitrogen concentrations in ponderosa pine
Covington, Sackett
To determine the effects of different burning intervals on soil N status in substands of sapling-, pole-, and sawtimber-sized ponderosa pine (Pinus ponderosa Laws.) we sampled plots burned at 1-, 2-, and 4-yr intervals by three strata at two depths…

Natural fire management in national parks
Parsons, Graber, Agee, van Wagtendonk
An evolving understanding of ecological processes, together with ambiguities in National Park Service policy, have led to multiple interpretations of the role of management in our large natural area National Parks. National Park Service management…

Responses of tree populations to climatic change
Brubaker
The influence of climate on the population dynamics of trees must be inferred from indirect sources of information because the long lifespans of trees preclude direct observation of population growth and decline. Important insights about these…

Forest disturbance and tree-ring analysis
Brubaker
Disturbance shapes the characteristics of individuals, populations, communities and ecosystems. As evidence mounts that disturbance influences virtually all vegetation types and levels of ecological organization, its role as a selective agent and…
