“…For each scenario, five replicate runs were conducted using independently generated random number seeds. Partial studies on the effects of SFI on the landscape processes in intensively managed forested landscapes in East Texas are available in Azevedo et al (2005a), Azevedo et al (2005b), and Azevedo et al (2006).…”

“…The habitats were modeled with HSI models using data provided by the growth and yield models and in few cases from assumptions based upon published data. Application of the HSI models is described in detail in Azevedo et al (2006). At the landscape level, HSI was calculated from the GIS coverages resulting from the landscape simulations.…”

We studied the changes in landscape pattern and function resulting from the application of the Sustainable Forestry Initiative (SFI) in East Texas, USA. Changes in landscape structure were studied by comparing landscapes with different management histories. A methodology to integrate landscape and stand pattern dynamics with processes was developed based upon modeling and simulation. The effects of pattern on processes were analyzed with this methodology considering the quality, quantity and configuration of vertebrate habitat and hydrological processes.Comparisons among landscapes revealed that forest management has a strong influence on landscape structure. The SFI program has increased overall fragmentation with an increase in number of patches, length of edges and shape complexity and a decrease in patch size, and number and size of core areas.Management according to the SFI program resulted generally in higher habitat suitability for many of the species analyzed and higher habitat diversity in the landscape. The SFI program induced fragmentation of the habitat of pine warbler and the establishment of narrow and elongated habitats in a network structure for most of the remaining species. Landscapes managed under the SFI program showed lower sediment yield at the watershed level than those under the non-SFI program due to lower channel erosion. The effects of the SFI program at the landscape level are related to the network of buffer strips.In general we conclude that relevant measures at the landscape level improve the sustainability of forested landscapes in East Texas.

“…However, direct comparisons are lacking for southern pine forest landscapes, and much of our supposition that riparian areas increase species richness and diversity is inferred from our knowledge of individual species biology. For example, Azevedo et al (2006) modeled SFI practices in an East Texas watershed and reported that implementation of SMZs was particularly beneficial in improving habitat suitability for an array of indicator wildlife species. Recommendations for SMZ widths to protect water quality may not be appropriate for meeting some objectives for wildlife communities.…”

Managing the Southern Pine Forest—Retained Wetland Interface for Wildlife Diversity: Research Priorities

Forest certification programs require program participants to manage for biodiversity using sciencebased information. Management at the interface of retained wetland features and plantations provides opportunities to enhance wildlife diversity on commercial pine forest lands. We review the scientific literature to document how wildlife in managed pine forests might benefit from retention of isolated wetlands and riparian zones, and potential effects of forest management on conservation of wetlandassociated wildlife on managed pine forests of the southern USA. We suggest research goals and methodologies to address information gaps critical to improved management. Many available studies lacked inferential power, and most depended on measures of diversity, richness, or abundance rather than community similarity or demographic measures of fitness. Observational studies have yielded potential hypotheses that should be tested with manipulative experiments. Demographic measures of fitness should replace potentially misleading measures of abundance or density, and diversity measures supplemented with comparisons of community similarity. Researchers should institute longterm studies to account for temporal variability. Multi-scale analyses would help determine appropriate management scale for isolated wetlands and the utility of riparian areas and associated streamside management zones as dispersal corridors. Landscape-level models would facilitate longterm planning and provide a framework for adaptive management.
