Societal Impact Statement Prescribed burning shows promise for managing certain grassland types, but relying solely on it often reduces plant diversity, including threatened species. In Japanese dry grasslands established volcanic ejecta, we explored conditions under which maintains high diversity. Lava grasslands, especially those young lava flows with hard, shallow, and acidic soil rock stone cover, harbored the most diverse plants, Burning helps prevent forest encroachment, efficiently maintaining species‐rich flows. We recommend this approach to land managers conserving particularly in conditions. Summary can be an effective efficient method large areas of face global increases abandonment. However, regular leads declines diversity plants species Eurasian countries. Therefore, investigating prescribed effectively conserves is highly important. hypothesized that specific physicochemical conditions, even burning‐only management maintain To test hypothesis, compared properties vegetation among burning‐managed different bedrocks (young/old scoria) Nashigahara, Yamanashi, Japan. quantitatively investigated how bedrock, soil, affected found highest were characterized by hard shallow than old young/old scoria grasslands.

ABSTRACT Aims Persistent land use change throughout the North American Great Plains increases need to maintain and improve ecosystem service delivery from remaining rangelands meet production conservation goals. Vegetation structure is an property influenced by management that has site selection implications for wildlife livestock. In this study, we investigated efficacy of patch‐burn grazing increase structural heterogeneity on semi‐arid post‐Conservation Reserve Program (CRP) grasslands in southwestern Dakota. Location Hettinger Research Extension Center Hettinger, Methods We surveyed plant community composition characteristics pastures during 2017–2020 summer seasons. Three were stocked with cow‐calf pairs three sheep. also units conventional (hay or idle) active post‐CRP enrolled summers 2018–2020. tested vegetative differences between patches varying time since fire grazer types using mixed‐effect models ordination. used variance partitioning determine if contrast increased over study period was higher relative management. Results Time significant all characteristics, recently burned being different other patches. There no cattle sheep pastures, but forb legume cover lower pastures. Structural greater than Conclusions Increased important supporting a broad suite rangeland can stabilize forage production. This supports expectation moderate stocking rates will regardless type, practitioners should consider which suites species may benefit.

Social conflict over rangeland-use priorities, especially near protected areas, has long pitted environmental and biodiversity conservation interests against livestock livelihoods. Social–ecological limits management adaptation creativity while reinforcing social disciplinary divisions. It can also reduce rancher access to land negatively affect wildlife conservation. Communities increasingly expect research organizations address complex dynamics improve opportunities for multiple ecosystem service delivery on rangelands. In the Greater Yellowstone Ecosystem (GYE), an area of western US, long-standing disagreements among actors who argue use those prioritize are limiting ranching Researchers at USDA-ARS US Sheep Experiment Station (USSES) along with University societal partners responding these challenges using a collaborative adaptive (CAM) methodology.

Mountains are biodiversity hotspots contributing essential benefits to human societies, but global environmental change is rapidly altering their habitats. During the past five decades, increasing temperatures and land-use in montane subalpine elevations facilitated productivity expansion of competitive vegetation, termed as "greening," with adverse effects on open grassland Although vegetation greening well-documented through satellite observations, its impact populations genomic integrity affected species remains underexplored. Here, we address this challenge by integrating 40 years remote sensing data museum genomics fieldwork assess mountain diversity plants southern Balkan peninsula. We sequenced genomes historical modern Ironwort, a plant significant medicinal value, demonstrate widespread erosion across populations. Our results show that, average, 6% (0%-20%) Ironwort's genome inbreeding accumulation over half century, indicating various degrees population declines. Importantly, that highly predictable normalized difference index (NDVI) rates change. models suggest faster increases density associated higher declines species, revealing negative impacts ecosystems.

Abstract Agriculture driven land-use change is a major contributor to insect declines globally. As result of population decline and subdivision, species lose genetic diversity, potentially reducing adaptive potential increasing load, reinforcing decline. We examine how diversity has changed over the past century in three Polyommatinae (Lepidoptera: Lycaenidae) butterfly southern Sweden, leveraging genome sequencing specimens from museum collections. Based on 63 historical 92 contemporary genomes, we document general reveal that extent depends habitat specialization. The generalist retained most its connectivity. In contrast, two specialists have declined sufficiently even common variation being eroded by drift, with up 3.3% reduction heterozygosity per decade strongly grassland associated Cyaniris semiargus . While this sharp reduced total load specialist species, increased isolation led inbreeding Cy. , exposing greater proportion homozygous state. This realized likely reduces mean fitness reinforces decline, highlighting need for well-connected landscapes maintain functional connectivity diversity. complement these analyses data seven additional uncovering are across group, alarming rates listed as viable. study highlights urgency incorporating into conservation planning, threats erosion not captured current assessment.
