In the United States, ponderosa pine (Pinus ponderosa) forests provide habitat for more cavity-nesting wildlife than any other forest type. In 2002-2005, stresses from drought, changes in the fire regime, and increases in forest density contributed t

Geography has discovered resilience theory, a body of thought about ecological change that initiated with C.S. Holling in the 1970s. We describe the similarities and differences between resilience theory and a geographical treatise, Thomas Vale's (19

We describe a model to investigate the effects of high-severity fire and drought on ponderosa pine regeneration using a water balance approach. Based on literature reviews and an analysis of annual and monthly correlations against tree regeneration,

In the American Southwest, mixed-conifer forest experienced altered disturbance regimes with the exclusion of fire since the early 1900s. This research analyzes patch development and tree spatial patterns in the middle versus upper mixed-conifer fore

By studying landscape form and patterns, we can study processes at multiple scales and determine how collectively those processes inform us about function(s). Integrating landscape ecology from a biogeographical perspective with geographic informatio

This study analyzed change of a coastal wetland using remote sensing, image processing, and GIS techniques. Aerial photographs from 1928, 1945, 1975, and 1994 were acquired for San Dieguito Lagoon, in San Diego County, California, USA. The photograph

Snags are important components of wildlife habitat, providing nesting and feeding sites for over 75 species of animals in the southwestern United States. Wildfires can increase or decrease the availability of snags to wildlife by killing live trees o

Patterns of stand development may be interpreted from spatial analyses, based on variables such as tree age and size, together with past records of climate and disturbance. In the present study, our objective is to examine spatial patterns of tree ag

The age structure in 1876, the last year of the natural frequent-fire regime, of an unharvested ponderosa pine forest in northern Arizona was reconstructed from living and dead dendrochronological samples. Approximately 20% of the trees were .200 yr
