Canopy closure around nest sites of Mexican spotted owls in northcentral Arizona
Article Abstract:
Management territories were established around certain sites occupied by Mexican spotted owls. These were devised based on estimates of canopy closure and roost and nest sites, but recommended areas of dense-canopy forest were scarce. An assessment of canopy closures around the sites aimed to resolve the problem, using photographic interpretations. It was found that northcentral Arizona spotted owls nested in areas where there was more than 70% of closed canopy forest. Also the most critical areas to manage were the 201 ha area incorporated in a 0.8 km radius of nest sites.

Hairy woodpecker winter ecology in ponderosa pine forests representing different ages since wildfire
Article Abstract:
The extent to which the winter ecology of hairy woodpeckers (Picoides villosus) in ponderosa pine (Pinus ponderosa) forests of northern Arizona, USA was affected by changes in vegetation structure and prey resources caused by wildfire was investigated. Hairy woodpeckers were seen to be relatively abundant in burned forests one or two years after fire while increasing time after fire resulted in home range size increasing across stands.

Prey ecology of Mexican spotted owls in pine-oak forests of northern Arizona
Article Abstract:
The diets and relative abundance and habitat associations of major prey species of Mexican spotted owls in pine and oak forest in north-central Arizona is studied. Conservation measures for the Mexican spotted owl are suggested.
