“…Upland habitat buffers are an NCBI practice; they are planted with diverse, native herbaceous flora to provide habitat for grassland birds and other wildlife in an agricultural matrix. These buffers are typically located in areas of lower crop yield and, thus, often have nominal impact on whole‐farm profitability (Barbour et al 2007, Stamps et al 2008). Previous research has confirmed that upland habitat buffers receive extensive use by breeding and nonbreeding bird communities (Smith et al 2005; Conover et al 2007, 2009), but little information exists on the importance of patch characteristics on bird productivity in buffers (Conover et al 2011).…”

Upland habitat buffers (i.e., strips of noncrop, herbaceous vegetation) that are established adjacent to wooded fencerows offer landowners an economical option to provide wildlife benefits within intensive agricultural landscapes. However, being located near a wooded edge may increase grassland bird vulnerability to edge effects through reduced nest survival. We examined nesting bird communities in field margins adjacent to wooded field edges with no buffer (i.e., control), narrow (approx. 10-m) buffers, and wide (approx. 30-m) buffers in an intensive agricultural system in the Lower Mississippi Alluvial Valley, United States. Dickcissel (Spiza americana) and red-winged blackbird (Agelaius phoeniceus) accounted for 97% of nests. Nest density was >7 times greater in wide buffers than in narrow. We modeled nest survival in Program MARK as a function of time (yr and season), nest-site, and local vegetation characteristics. Nest survival was influenced by among-and within-season temporal effects and local vegetation structure, but not by buffer width. Nest success varied substantially between years and within seasons for dickcissel (12.9% and 19.1% early in the seasons of 2003 and 2004, respectively), but not for red-winged blackbird (15.1%). Overall nest-success estimates were similar to noncrop, herbaceous strips elsewhere in the United States, though whether or not these estimates represent population sinks remains uncertain. Based on this research, we advocate integrating upland habitat buffers within intensive agricultural landscapes and emphasize the use of wide buffers when grassland-nesting birds are a conservation priority. ß 2011 The Wildlife Society.

“…We recommend conservation efforts focus on ensuring available usable space through maintaining upland deciduous woodlands or providing herbaceous fields in varying degrees of succession when managing for wild turkey populations in mixed forest‐agricultural landscapes. Additionally, supplementing buffers along forest‐agricultural field edges would marginally affect existing agricultural practices (Barbour et al ) and may be of particular value to turkeys.…”

Female wild turkey habitat selection in mixed forest‐agricultural landscapes

Gradual changes in agricultural and landscape management practices have led to growing uncertainty regarding eastern wild turkey (Meleagris gallopavo silvestris) habitat management in contemporary landscapes in the midwestern United States. Nesting and brood‐rearing success during spring often influence turkey population trajectories, and a better understanding of habitat selection during this period would identify potential habitat characteristics that have the greatest influence on turkey population management objectives. We evaluated spring (8 Apr–24 Jul) habitat selection of 89 radio‐marked female wild turkeys across 4 study areas (2 forest‐dominated, and 2 agricultural) in southwest and west‐central Wisconsin, USA, 2010–2011. We investigated habitat selection at 3 hierarchical spatial scales: study areas, within spring areas of use (SAUs), and within 200 m of nest sites. We obtained 3,605 radio‐telemetry relocations (truex¯ = 30.8 ± 0.51 [SE] locations/turkey) and monitored 79 nesting attempts. In both landscapes, female turkeys selected edges, and in forested landscapes females selected for deciduous forests with numerous and dispersed forest openings. Female turkeys generally established SAUs where an even mixture of forest and open‐herbaceous cover was available. Telemetry locations within SAUs indicated female turkeys selected land cover types in proportion to availability (Ŝi = 1), but selection of specific cover types was variable within and among study areas. At the nest site scale, amount of forest‐field edge was greater within 200 m of nest sites (truex¯ = 62.2 m/ha) compared to random locations (truex¯ = 48.3 m/ha). Coarse measures of forest and open‐agricultural cover were useful in identifying habitat selection trends by female turkeys across hierarchical scales. Our results suggest that proportion and configuration of forest and open‐agricultural cover are essential components of female turkey habitat, and forest‐field edge further plays an important role in nest site selection. We suggest conservation efforts focus on ensuring available usable space through maintaining upland deciduous woodlands or providing herbaceous fields in varying degrees of succession when managing for wild turkey populations in mixed forest‐agricultural landscapes. Adaptability of wild turkeys indicates the importance of multi‐scale habitat evaluation prior to implementing habitat management strategies. © 2016 The Wildlife Society.

“…Stull et al () was the first to use precision agriculture to quantify the economic outcome of conservation practice enrollment to improve water quality (Filter Strips). Barbour et al () expanded their work to address economic outcomes of a wildlife‐focused conservation practice (CP‐33, Habitat Buffers for Upland Birds). These 2 seminal approaches to incorporating economic considerations into strategic conservation planning essentially initiated a new form of ‘targeted conservation’ delivery, where profitability of conservation enrollment is incorporated into decision‐making.…”

Agricultural landscapes are important for natural resource conservation, but present numerous obstacles associated with intensive agricultural production. Chief among these challenges is the competing economics outcomes of conservation and crop production. Understanding these outcomes requires quantifying economics of crop production and conservation enrollment. Precision agriculture technology provides a mechanism to address these needs by using advanced technology to quantify spatially explicit profitability in agricultural fields. Precision agriculture's application to conservation planning represents a growing field of research. I present a brief overview of precision agriculture technology and its application in natural resource conservation. I discuss the role precision agriculture can play in United States conservation policy, highlight hindrances to adopting this technology, and provide recommendations for future application. I outline a new approach of targeted conservation delivery that focuses on return on investment to agricultural producers and discuss the role of precision agriculture in this approach. Increased adoption and application of this technology in natural resource conservation will require substantial investment from state wildlife agencies, nongovernmental organizations, farm managers, rural banks, and agricultural companies. Precision agriculture represents the next paradigm shift in natural resource conservation where spatially explicit conservation decisions are made that optimize conservation and profitability to produce environmentally resilient, multifunctional agricultural landscapes.
