“…Because of these idiosyncratic responses among species, it would be difficult to implement a single, comprehensive management plan that addresses the specific habitat needs of each and every species. Instead, a focus on multiscalar management (or mosaic management) may provide more comprehensive guidance to land managers [ 93 ], allowing the evaluation of the contribution of fragments outside protected areas in the regional landscape [ 33 ]. The lack of a consensus in the species responses both within and among spatial scales may challenge simplistic and blueprint approaches [ 94 ].…”

Does scale matter? The influence of three-level spatial scales on forest bird occurrence in a tropical landscape

Consequences of habitat fragmentation for species occurrence are amongst the most important issues in landscape and conservation ecology. Empirical and theoretical studies have demonstrated that the total amount of habitat, patch size and connectivity have nonlinear effects on species survival on multiple spatial and temporal scales. Therefore, population models need to incorporate multiple scales, which can be extremely valuable to prioritizing conservation efforts in these changing landscapes. We tested how the amount and configuration of habitat affect understory bird species occurrence using fine to broad-scale habitat features. We used playback to sample birds in 13 Atlantic Forest fragments in Southeast Brazil. Microhabitat, local and regional landscape variables were tested against bird occurrence. Our results demonstrate that different bird species respond to different habitat scales. Sclerurus scansor, Xiphorhynchus fuscus, Automolus leucophthalmus, Drymophila ochropyga, Mackenziaena leachii, and Chiroxiphia caudata were most influenced by tree height and diameter (microhabitat characteristics), S. scansor, F. serrana and Pyriglena leucoptera were most influenced by forest cover and red-edge reflectance(local-scale metrics) and S. scansor, X. fuscus, D. ochropyga, P. leucoptera, F. serrana and M. leachii had area, core area and functional connectivity index (landscape features) as stronger predictors of species occurrence. Small forest fragments acted as corridors and increased overall connectivity of the entire community. The most effective means of maintaining long-term population connectivity of understory birds involves retaining both large and small areas, including forests with different micro-habitat characteristics. No management approach based on a single-scale would benefit all species. Implementing multiscale conservation strategies are necessary for maintaining long-term viability of forest birds on tropical landscapes.

“…There have been few studies on the multiscale response of birds to habitat characteristics [ 12 , 28 – 33 ] or for mammal species [ 11 , 34 ]. According to Boscolo and Metzger [ 1 ], landscape models that combine multiscale metrics are better predictors of bird occurrence in forest fragments than models that use a single scale.…”

“…Greater patch size, but not greater cumulative pine habitat on the landscape, is an important driver of Brown-headed Nuthatch abundance patch (Wood and Quinn 2016). Thus, interested private landowners can maintain and re-establish pine stands on their property regardless of their location on the urban-rural gradient or proximity to other forest patches.…”

“…Indeed, the growing literature on conservation successes in human systems is full of surprises (Martin et al 2014) where traditional conservation practice has focused on the pristine and untouched rather than on conservation opportunities within human-shaped ecosystems. For example, it was unexpected that the threatened Brown-headed Nuthatch was more abundant in pine patches embedded within residential developed land in the Piedmont than in patches embedded within rural or forested land use types (Wood and Quinn 2016). This surprise should be seen as a conservation opportunity given that suitable habitat is not always indicated by an undisturbed, large contiguous tract of pristine or native habitat disconnected from human systems.…”

ABSTRACT. Conservation science addresses the complementary goals of preventing future biodiversity loss while sustaining critical human foundations. In this paper we use two case studies focused on land management to discuss how private lands conservation can be more effective by considering how planning and decision making reflects a coupled human and natural system (CHANS). The first case study focuses on conservation easements in the temperate forests of eastern United States; the second focuses on conservation opportunities in Midwestern agroecosystems, in particular the value of agroforestry. For each case study we discuss the natural and human subsystems, how elements and interactions within and between subsystems (as organized by elements of CHANS) create challenges and opportunities for conservation, and the importance of considering relevant scales of subsystems. Review of these case studies demonstrates that additional insight gained by using a CHANS perspective, particularly given how the subsystems interact at different scales, improves identification of important points of social and ecological overlap, ultimately enhancing conservation research, planning, and practice.

“…Our study examined the effects of habitat variation on adult dragonfly communities in the Piedmont Ecoregion of South Carolina, USA. This region was previously dominated by forest cover consisting of mixed southern hardwoods, but the region experienced the largest net loss in forest cover in the Eastern USA in the past 40 years due to anthropogenic habitat conversion (Wood & Quinn, 2016). Wetlands have also been lost, converted to agriculture and urban development (Dahl, 1990;1999).…”

Dragonflies (Insecta: Odonata) use both aquatic and terrestrial ecosystems, and the abundance and diversity of odonates should be good indicators of habitat integrity. To determine which environmental variables affect odonates, we sampled adult dragonflies three times at 12 sites in Pickens and Greenville Counties, SC, USA, in different habitats, at different spatial scales, across a landscape gradient from intact forest to urban locations. At each site, we established two 2 m × 20 m plots along the shoreline of each aquatic habitat. We sampled dragonflies in ten 2 m × 2 m subplots/plot, described the vegetation and substrate in these subplots and adjacent aquatic subplots, and measured the percent cover of different landforms within 500 m of each plot center. Using nested ANOVA and Akaike information criteria models, habitat type and correlating environmental variables (substrate type and bank vegetation) were the best predictors of community structure at all spatial scales. Streams and rivers had fewer individuals and species than lakes, and had a nested subset of species found in lake communities. Landscape elements were also important, with indices declining as barren land and grasslands increased. At the largest scale, anthropogenic changes to the landscape had mixed effects. Small habitats isolated in urban areas had a significantly depauperate, nested subset of species found in communities inhabiting larger natural areas. However, odonate abundance and diversity was highest at human-made lakes and ponds, suggesting that these anthropogenic features help maintain odonate communities.
