This study examined the extent, trends, and drivers of LULCC within and around Mkomazi National Park over a 30-yr period (1994–2023). Using remote sensing, geographic information systems (GIS), and supervised image classification techniques, changes in five land cover classes—vegetation, water, bare land, agricultural land, and settlements—were analyzed. Household survey, direct observation, focus group discussions, and key informant interviews were also conducted in the study area to identify human-induced drivers of LULCC. Results indicated significant changes in land use and land cover within the study area. Between 1994 and 2023, there was overall decrease in dense vegetation and water coverage, whereas agricultural land, bare land and settlements increased by varying percentages. Additionally, it was found that agriculture (67%), settlement expansion (20%), and population growth (13%) emerged as the primary drivers of LULCC patterns. The study emphasizes the need for integrated land-use planning, community engagement, and enforcement of conservation regulations. Strategies such as sustainable land management, habitat restoration, and awareness campaigns are essential to mitigate adverse LULCC impacts and to ensure the long-term conservation of biodiversity in and around Mkomazi National Park.</div></div>","PeriodicalId":49634,"journal":{"name":"Rangeland Ecology & Management","volume":"102 ","pages":"Pages 37-47"},"PeriodicalIF":2.4,"publicationDate":"2025-09-01","publicationTypes":"Journal Article","fieldsOfStudy":null,"isOpenAccess":false,"openAccessPdf":"","citationCount":null,"resultStr":null,"platform":"Semanticscholar","paperid":"144572341","PeriodicalName":null,"FirstCategoryId":null,"ListUrlMain":null,"RegionNum":3,"RegionCategory":"环境科学与生态学","ArticlePicture":[],"TitleCN":null,"AbstractTextCN":null,"PMCID":"","EPubDate":null,"PubModel":null,"JCR":null,"JCRName":null,"Score":null,"Total":0}

We also hypothesized that the proportion of time allocated to the most recently burned patches would not significantly differ between livestock species. We compared TSF across burn seasons and quantified patch selection using Ivlev’s electivity index. Our results showed that both livestock species selected for recently burned patches, with selection decreasing as TSF increased. For cattle, patch selection was influenced by TSF and burn season. Goat patch selection was also related to TSF, but showed more variability in response to burn season and TSF duration. In dormant season burns, both livestock species selected for the most recently burned patches, while selection following growing season burns peaked at 6–11 months TSF.

However, no study has yet attempted to analyze this regulatory gap (i.e., the absence of Rangeland Law), and studies on interlinkages between the institutional void and rangeland degradation continue to be rare in Mongolia. By employing a qualitative research method involving policy documents and semistructured interviews, this study addresses these gaps from a novel perspective by examining the institutional and actor-oriented factors that have impeded the adoption of the Rangeland Law for the past decades based on the Actor-Centered Institutionalism framework. The research findings indicate that institutional factors influence the adoption of the Rangeland Law more strongly than actor-oriented factors and that the challenges facing rangeland governance in Mongolia are deeply intertwined with political dynamics and vested interests.

In this research, forage production in north-central Iran rangelands was modeled by analyzing the effective precipitation during 10 water years, from 2005–2006 to 2014–2015. The production of key species, including <em>Artemisia sieberi, Ephedra intermedia, Zygophyllum eurypterum, Stipa barbata, Scariola orientalis, Anabasis setifera</em>, and annual plants, was measured. The relationship between forage production and total precipitation amounts, total precipitation exceeding 1, 3, 5, 7, and 10 mm, and temperature was quantified, and an optimal multivariate regression model was introduced to predict regional forage production for each species. Results revealed an average annual forage production of 57.71 kg · ha<sup>−1</sup>.

Pre-emergent herbicides are an effective restoration tool to reduce annual grasses but can negatively impact seeded vegetation. Hence, seeding is often delayed until herbicide activity has abated. With indaziflam, a pre-emergent with longer soil activity, seeding may need to be delayed for several years. It would be advantageous if seeded species could establish while indaziflam controls annual grasses, as competition with annual grasses would be limited, and forage production and vegetation cover of the soil surface would recover sooner. Seeding deeper in the soil may allow seeded species to largely avoid herbicide activity, but seeded species may struggle to emerge from greater seeding depths. We investigated seeding squirreltail and crested wheatgrass at 1-, 3-, 5-, and 7-cm seeding depths just prior to a fall indaziflam application at two sites in 2 yr. Seeding at ∼1-cm is the recommended practice for both bunchgrasses. Seedling density in late June was greater at the 3 and 5 cm seeding depths and likely greater at the 7 cm depths than at the 1-cm depth. Seedling height was greater at the 3-, 5-, and 7-cm depths than at the 1-cm depth. Seedling density and height did not vary among the 3-, 5-, and 7-cm depths. This suggests that indaziflam largely did not penetrate below the first centimeter or two of the soil the growing season after application. Seeding at depths of 3–7 cm is likely a viable strategy for allowing some seeded species to establish while indaziflam controls annual grasses. Additional evaluations across a gradient of soil and site characteristics, with different plant species and functional groups, and other pre-emergent herbicides are needed to refine this restoration strategy and identify its benefits and limitations.</div></div>","PeriodicalId":49634,"journal":{"name":"Rangeland Ecology & Management","volume":"102 ","pages":"Pages 139-144"},"PeriodicalIF":2.4,"publicationDate":"2025-09-01","publicationTypes":"Journal Article","fieldsOfStudy":null,"isOpenAccess":false,"openAccessPdf":"","citationCount":null,"resultStr":null,"platform":"Semanticscholar","paperid":"144655712","PeriodicalName":null,"FirstCategoryId":null,"ListUrlMain":null,"RegionNum":3,"RegionCategory":"环境科学与生态学","ArticlePicture":[],"TitleCN":null,"AbstractTextCN":null,"PMCID":"","EPubDate":null,"PubModel":null,"JCR":null,"JCRName":null,"Score":null,"Total":0}

CM efficiency is driven by the education of the head of household, the area of grassland, income from non-livestock and technical training, while NCM efficiency is shaped by age, Mandarin proficiency, family size and the quality of grassland under management. The findings underline the role of cooperatives in improving technical and scale efficiency, but also highlight the allocative inefficiencies in cost management.
