We Studied microhabitat use by black-faced impala in different herd types during the rut in the cold dry seasons of 2001 and 2002 in the Etosha National Park, Namibia. We investigated whether black-faced impala select feeding sites consistently for their microhabitat characteristics in 2 vegetation types, Karstveld and Tamboti Woodland. We also investigated intra-population differences in microhabitat use between herds of different types. In both habitats, sites used by impala for feeding were more likely to be in the shade, within 2 m of the edges of wooded areas and grassy clearings, with high visibility at I m height, and with lower grass swords than nearby nonfeeding sites. In Karstveld, feeding sites of impala were also located closer to the nearest shrub than were nonfeeding sites. A degree of fine-scale sexual segregation in microhabitat use was demonstrated, but it was not consistent across habitats. Incorporating these trends in the microhabitat use of black-faced impala into management, decisions should maximize the success Of Small populations released at selected off-park sites.

Within the expanding city of Brisbane in south-east Queensland, numerous fragments of native and regrowth vegetation are scattered across the largely urbanised landscape. These fragments provide refuge to a great diversity of native wildlife, and, provide residents with the opportunity to experience nature on their doorstep. To assess the diversity and abundance of this wildlife, recent changes in these parameters, and the value of wildlife and bushland fragments to residents of Brisbane, a questionnaire survey was distributed to 300 households each located adjacent to one of 38 urban bushland fragments. A total of 172 surveys (57%) were returned, producing 768 records of 83 fauna species, dominated by birds and mammals; bandicoots were widely reported from the 38 fragments. Several historical records provided evidence of recent local extinctions within fragments, highlighting the continuing declines in various species of native wildlife within Brisbane. Several human-wildlife conflicts were identified, but overall residents were tolerant of such conflicts. Bandicoots were disliked by a small minority (3%) of residents owing to the holes they dig in lawns and gardens in search of food. and their potential as vectors of ticks. Most respondents expressed ail appreciation for the presence of native wildlife (96%) and bushland fragments (97%) in their local area, emphasising the importance of incorporating human dimension values into the management of this urban biodiversity.
