Trade-offs relating to grassland and forest mine reclamation approaches in the central Appalachian region and its implications for the songbird community

Abstract

Surface mining in the Appalachian region, USA, converts large areas of mature forest to early-successional habitat. This shift in landscape structure has the potential to reduce habitat availability and suitability for forest-dwelling songbirds by reducing and fragmenting mature forest, but also to increase habitat availability for grassland and shrubland-associated songbirds. We examined the influence of mountaintop mining/valley fill (MTMVF) reclamation habitats (grassland, shrubland, and remnant forest) on songbird community composition and abundance at three former MTMVF mines in southwestern West Virginia, relative to intact forest. We quantified the songbird community in 1999 and 2000 using point counts arranged throughout the mine complexes to assess landscape composition of the songbird community. Community analysis showed songbirds had strong associations with their respective guild based on species’ habitat preferences. Although remnant and intact forest treatments had similar species compositions, the forest interior guild had greater richness in intact than remnant forest. Total species richness was greatest in the reclaimed shrubland treatment. Focal species analysis followed similar trends as community assessments, as species’ abundances within treatment types were strongly associated with species’ habitat preferences. Our study indicates reclamation habitat decisions (i.e. grasslands versus forests) can have large effects on avian community composition. Determining appropriate mine restoration actions depends on the suite of species desired for long-term occupancy and their conservation priority.

Long-term monitoring identifies increase in Henslow’s Sparrow (Centronyx henslowii) abundance following fire management in a North Carolina grassland

Understanding population responses to environmental change is critical for assessing vulnerability, resilience, and habitat management needs. We assessed Henslow’s Sparrow ( Centronyx henslowii ) abundance and breeding productivity in an isolated North Carolina grassland (1149 ha) that transitioned from unmanaged to fire-managed during 2011–2024. Fire management was initiated in 2016, where approximately 1/3 of the grassland is burned annually in late summer on a rotating basis, resulting in a full burn cycle of roughly three years. We used hierarchical distance sampling models to estimate the change in Henslow’s Sparrow abundance before and after fire management from point count data (45–50 locations surveyed annually). Estimated average abundances (i.e., expected number of singing male sparrows per site) significantly increased from 1.387 individuals per survey location pre-management (95% credible interval [CI]: 0.822–2.267) to 3.124 post-management (CI: 2.235–4.385), resulting in annual population sizes ranging from 56 singing male sparrows in 2012 (CI: 36–85), to 411 in 2022 (CI: 342–498). From 2022 to 2023, average brood size was 3.148 (95% confidence interval [CI]: 2.637–3.659) and survival probability for a 24-day nesting cycle was 0.693 (CI: 0.369–0.897). Apparent nesting success was 70–89%, much higher than reported in previous studies (19–62%). Increased abundance post-management indicates that Henslow’s Sparrows are responding positively to the use of prescribed fire, while the estimated rates of breeding productivity indicate the species likely has the capacity to sustain the local population. This study provides baseline information for managers to monitor population status, while laying the foundation to identify regulatory mechanisms and gauge the effectiveness of the current fire management strategy in maintaining an isolated population of Henslow’s Sparrows.

Extrinsic factors similarly affect nest survival of a threatened shorebird in natural and human-created habitats

Knowledge of factors that influence nest survival can inform effective conservation management for imperiled avian species. Habitat availability and quality are common priorities of conservation efforts, and climate and interspecific associations can also affect survival rates. In the lower Platte River system of eastern Nebraska, USA, Piping Plovers ( Charadrius melodus , hereafter plovers) nest on river sandbars and different types of human-created off-river sites (i.e., sand and gravel mines, housing developments, and transitional sites) that are unique within the Northern Great Plains breeding population. However, off-river habitat may not be suitable for plover nesting long-term because of reduced habitat availability on both river sandbars and off-river sites. We evaluated plover nest survival at off-river and sandbar sites using data from 2008 to 2023 (n = 285). In addition, we examined the effects of extreme temperatures, proximity to conspecific and Interior Least Tern ( Sternula antillarum athalassos , hereafter tern) nests, and temporal factors on nest survival. Plover nest survival did not differ between off-river sites and sandbars or amongst different off-river site types. Daily nest survival was 0.9818 (95% CI = 0.9729–0.9878) from 2008 to 2013 (unexclosed; n = 87) and 0.9950 (0.9918–0.9970) from 2014 to 2023 (exclosed; n = 198). Nest survival increased with the proportion of above average temperature days, increased with proximity to neighboring tern nests, and decreased with later nest initiation dates. Therefore, prioritizing early season nests, recognizing the benefits terns provide to plover nest survival, and monitoring the effect of climatic trends may aid future conservation efforts. Finally, as nest survival at off-river sites is comparable to sandbars, the predicted decline of habitat provided at off-river sites may reduce the overall breeding productivity and abundance of plovers in the lower Platte River system with ramifications to broader population viability.

King Rails in southeastern Arkansas are majority resident

King Rails ( Rallus elegans ), a declining species of secretive marsh bird, have a mixed migratory strategy, with some individuals migrating and some being year-round residents. Determining the distribution of migratory versus resident King Rails is critical to guiding habitat management and assessing risks to populations. We examined the migratory status of adult King Rails at the Choctaw West Wildlife Management Area in southeastern Arkansas, the only known site in Arkansas with multiple breeding pairs. Of the 23 adult King Rails we tagged in 2022 and 2023, two birds migrated away from the local area, one in each year. One migrated 145 km, and the other 450 km. Our findings suggest that the line between the migratory and resident range of Arkansas King Rails could be north of our site.
