Effects of management regime on the abundance and nest survival of shrubland birds in wildlife openings in northern New England, USA

Many shrubland bird species are declining in eastern North America and as a result forest managers have used a variety of techniques to provide breeding habitat for these species. The maintenance of permanent “wildlife openings” using prescribed burns or mechanical treatments is a widely used approach for providing habitat for these species, but there have been no studies of the effects of treatment regime on bird abundance and nest survival in managed wildlife openings. We studied shrubland birds in wildlife openings on the White Mountain National Forest (WMNF) in New Hampshire and Maine, USA, during 2003 and 2004. We analyzed bird abundance and nest survival in relation to treatment type (burned versus mowed), treatment frequency, time since treatment, and patch area. We found that wildlife openings provided habitat for shrubland birds that are not present in mature forest. There was relatively modest support for models of focal bird species abundance as a function of treatment regime variables, despite pronounced effects of treatment on habitat conditions. This probably was attributable to the combined effects of complex site histories and bird site fidelity. Overall nest success (52%) was comparable to other types of early-successional habitats in the region, but there were few supported relationships between nest survival and treatment variables. We conclude that wildlife openings provide quality habitat for shrubland birds of high conservation interest as long as managers ensure treatment intervals are long enough to permit the development of woody vegetation characteristic of the later stages of this sere. Also, wildlife openings should be large enough to accommodate the territory sizes of all target species, which was ≥1.2 ha in this study.

Habitat use and nest success of scrub-shrub birds in wildlife and silvicultural openings in western Massachusetts,USA

Many conservationists are concerned about reports of declining populations of scrub-shrub birds. Wildlife opening management, involving repeatedly burning or mechanically treating early-successional stands, is one strategy for creating habitat for these species, but this practice is costly. Some silvicultural treatments also create scrub-shrub habitat and have the advantage of potentially generating revenue, but the relative effectiveness of wildlife opening management and silviculture for creating bird habitat is not known. During 2004 and 2005, we compared scrub-shrub bird abundance, nest success, and habitat characteristics between wildlife and silvicultural openings in western Massachusetts to determine whether the habitats created by these practices are equivalent for birds. We recorded 1927 detections of 31 scrub-shrub bird species during the course of the study and monitored 368 nests. We found that although most species were present in both treatments, many differed in abundance between wildlife and silvicultural openings, including several species of high conservation concern. These differences were attributable to differences in habitat characteristics between treatments. The overall probability of a nest surviving to fledging was 0.43, and did not differ between wildlife and silvicultural openings. Our results indicate that the habitat quality of wildlife and silvicultural openings is not equivalent for scrub-shrub birds, but the two management approaches serve as complementary strategies for maintaining these declining species.

Projecting the bird community response resulting from the adoption of shelterbelt agroforestry practices in Eastern Nebraska

Evolving agricultural policies have influenced management practices within agroecosystems, impacting available habitats for many species of wildlife. Enhancing wildlife habitat has become an explicit objective of existing agricultural policy. Thus, there is renewed focus on field borders and the use of shelterbelt agroforestry systems to achieve conservation goals in the Midwest. Two Representative Farms – a 283-ha dryland and 510-ha irrigated farm were created in Saunders County, Nebraska. The Habitat Analysis and Modeling System (HAMS) was used to describe the composition and spatial pattern of the existing farms and surrounding landscape, as well as for the landscapes surrounding selected Breeding Bird Survey (BBS) routes. Simulated land use changes resulting from the implementation of two shelterbelt scenarios, Agricultural and Wildlife, were incorporated on each Representative Farm and surrounding landscape. Landscape variables which influence breeding bird species richness and community composition as determined from BBS routes were measured on simulated farm landscapes. A more heterogeneous landscape results from implementing either scenario. The percent total woods was a significant determinant of bird species richness on the BBS routes and was important in influencing bird communities at the farm- and landscape-level. Other landscape metrics which influenced the bird community composition on BBS routes were woody edge percentages and edge density values. Policies promoting shelterbelts create edge habitats which ultimately favor birds within the Forest-edge/generalist guild while bird species in need of conservation such as grassland-field species would potentially be negatively affected.
