Land use–land cover (LULC) alteration is primarily associated with land degradation, especially in recent decades, and has resulted in various harmful changes in the landscape. The normalized difference vegetation index (NDVI) has the prospective capacity to classify the vegetative characteristics of many ecological areas and has proven itself useful as a remote sensing (RS) tool in recording vegetative phenological aspects. Likewise, the normalized difference built-up index (NDBI) is used for quoting built-up areas. The current research objectives include identification of LULC, NDVI, and NDBI changes in Jhelum District, Punjab, Pakistan, during the last 30 years (1990–2020). This study targeted five major LULC classes: water channels, built-up area, barren land, forest, and cultivated land. Satellite imagery classification tools were used to identify LULC changes in Jhelum District, northern Punjab, Pakistan. The perception data about the environmental variations as conveyed by the 500 participants (mainly farmers) were also recorded and analyzed. The results depict that the majority of farmers (54%) believe in the appearance of more drastic changes such as less rainfall, drought, and decreased water availability for irrigation during 2020 compared to 30 years prior. Overall accuracy assessment of imagery classification was 83.2% and 88.8% for 1990, 88.1% and 85.7% for 2000, 86.5% and 86.7% for 2010, and 85.6% and 87.3% for 2020. The NDVI for Jhelum District was the highest in 1990 at +0.86 and the lowest in 2020 at +0.32; similarly, NDBI values were the highest in 2020 at +0.72 and the lowest in 1990 at −0.36. LULC change showed a clear association with temperature, NDBI, and NDVI in the study area. At the same time, variations in the land area of barren soil, vegetation, and built-up from 1990 to 2020 were quite prominent, possibly resulting in temperature increases, reduction in water for irrigation, and changing rainfall patterns. Farmers were found to be quite responsive to such climatic variations, diverting to framing possible mitigation approaches, but they need government assistance. The findings of this study, especially the causes and impacts of rapid LULC variations in the study area, need immediate attention from related government departments and policy makers.

Plant diversity is lower in arid regions around the world. However, semi-arid regions have very high species richness and are notable in terms of vegetation structure and plant diversity. The major goal of this study was to assess the composition and diversity of woody species with respect to edaphic properties in semi-arid lowlands of Kasur, Punjab Pakistan. Comprehensive field surveys were conducted to study the botanical diversity of woody vegetation in Kasur district (Punjab) during 2020–2022. Based on geography and vegetation richness, 120 sampling sites were selected, with each site comprising 05 transects of 500 m² randomly. Therefore, from each sampling site, 25 quadrats were taken for exploring the biological assortment of woody vegetation. Soil samples were collected at a depth of 9 to 12 cm and placed in a polythene bag. The soil samples were tested for soil pH, EC, OM, macronutrients (N, P, and K), and cation exchange capacity (CEC). A total of 86 woody species belonging to 61 genera and 26 families were documented from diverse habitats of semi-arid lowland of Kasur, Punjab, Pakistan. The leading family was Leguminosae having 13 genera and 21 species, followed by Moraceae, including four genera and nine species, and Bignoniaceae with seven genera and 09 species. Overall, five woody plant communities were renamed by means of the maximum indictor-valued plant species, such as those listed below; 1. EDM: Eucalyptus-Dalbergia-Morus community; 2. PBM: Populus-Bombax-Morus community; 3. ZTZ: Ziziphus-Tamarix- Ziziphus community; 4. PAP: Prosopis-Acacia-Prosopis community, and 5. BCR: Broussonetia-Conocarpus-Ricinus community. The CCA ordination makes it apparent that appropriate edaphic aspects, such as pH, organic matter, N, P, K, soil texture (silt, sand, and clay), and cation exchange capacity (CEC), have a significant influence on how woody species are distributed. The current effort provides a fundamental layout to realize the influences of environmental variables on the arrangement, variety, and relations of woody vegetation, which is useful to improve the conservation and management events for the ecological restoration of degraded habitation in the studied district.

Edaphic properties have been widely shown to influence community composition and distribution. However, the degree to which edaphic factors can affect grasses in semi-arid lowlands is still little researched. We assessed the significance of nine edaphic factors to explain the distributions of 65 grass species with various ecological traits (i.e., the ecological indicator values for their preferred habitat) in the semi-arid lowlands of Pakistan. To record information on species composition and related ecological conditions, we selected 10 random sampling locations between 2020 and 2021. For each species, we determined the important value index (IVI) and looked at the primary indicator species that were identified using the indicator species analysis approach. The major genera were Setaria, Brachiaria, and Cenchrus with 6.15% species in each followed by Aristida, Panicum, and Eragrostis with 4.61% wild grass species, Bothriochloa, Bromus, Phragmites, Polypogon, Saccharum, Poa, Echinochloa, and Dactyloctenium with 3.07% species, whereas other genera had a single species each. In total, 80% of the species were native, while only 20% were introduced species. Microphylls accounted for 49.23% of the leaf size spectra of the grass flora in the study area. The other frequent traits included macrophylls (21.53%), nanophylls (20%), and leptophylls (9.23%). The major life forms were therophytes (56.92%) followed by hemicryptophytes (38.46%) and geophytes (4.61%). The results of an ordination analysis indicated that the distribution of grasses was significantly (p ≤ 0.002) influenced by several edaphic parameters, with pH having the greatest impact on species distribution. The analyses of indicator species showed that pH and EC were the most powerful and important edaphic factors for determining the composition of plant communities and indicator species. The significant indicator species in various ecosystems were Cynodon dactylon (L.) Pers. rainer.bussmann@smnk.de and Leptochloa chinensis (L.) Nees (agroecosystem), Brachiaria reptans (L.) C.A. Gardner and C.E. Hubb, Dichanthium annulatum (Forssk.) Stapf, and Saccharum spontaneum L. (forest ecosystem), Cenchrus biflorus Roxb., Cenchrus ciliaris L., and Desmostachya bipinnata (L.) Stapf (urban ecosystem), Arundo donax L., Echinochloa crus-galli, and Phragmites australis (wetland ecosystem), and Saccharum spontaneum and Echinochloa crus-galli (L.) P. Beauv. (riparian ecosystem). We discovered that different species groupings had different habitat preferences and that soil pH had a significant beneficial effect on plant variety. These results provide a scientific roadmap for soil and plant restoration in semi-arid lowland habitats.

Climbing plants have an important role in forest communities and ecosystems. Despite the significance of the climbers in ecosystems, most of the previous research work in Pakistan has been concentrated on trees, shrubs, and herbs, with little attention paid to climbing plants. The current study investigated the ecology of climbers and the influence of soil characteristics on diversity, richness, and indicator species distribution in the Changa Manga Forest Plantation, Punjab, Pakistan. Field surveys were carried out between 2020 and 2021, with the data gathered using a random sample approach for ordination and cluster analysis of each plant species and edaphic data from sample plots. We reported a total of 29 climber species belonging to 23 genera and 9 families from the area. The Convolvulaceae family was the most prevalent, followed by Apocynaceae and Cucurbitaceae. Herbaceous climbers were the typical life form (70% species) and species showed peak flowering during the months of August and September. The multivariate analysis and cluster analysis grouped the climbers into four distinct communities based on the indicator species, representing filtering of the species pool in the studied area. Canonical Correspondence Analysis (CCA) results showed that soil factors had a significant influence (p ≤ 0.002) on the climbers’ diversity and distribution pattern. Our research contributes to a deeper understanding of climbing plant ecology in response to soil variables, with immediate consequences for policy and practice in this Himalayan region, as well as research insights for neighboring Himalayan regions and elsewhere in the world.

The burgeoning human population exhibited a rapid amplification in demand for timber and fuelwood and as a result, the natural population of the native tree Tecomella undulata reduced rapidly due to its high economic and medicinal significance. The recognition of appropriate regions for threatened plants in the climate change scenario is a fundamental step for the restoration and conservation of biodiversity. The current study predicts the potentially suitable areas in Pakistan for T. undulata restoration. This research identifies the highly appropriate regions for vulnerable T. undulata through the maximum entropy model from MaxEnt software. The model’s Area Under Curve 0.968 suggested its accuracy. The mean temperature of the wettest quarter, precipitation of the warmest quarter, and mean temperature in the driest quarter significantly shaped the T. undulata distribution. Future suitable areas for T. undulata were made by using RCP (4.5 and 8.5) for the years 2050 and 2070 through 19 bioclimatic variables and 66 occurrence points. The current highly suitable area for T. undulata is approximately 135,749 km² (15.4%) while the unsuitable area identified is approximately 404,917 km² (45.91%). The highly suitable area for T. undulata increases by 3.6–7% under climate change regimes (RCP 4.5 and RCP 8.5). The Central Punjab (District Faisalabad, Nankana sahib, Jhang, Kasur, and Okara), Salt Range, Western Khayber Pakhtunkhwa (KPK), FATA area, Eastern Balochistan, and Thar and Tharparker in Sindh are the current appropriate habitats for T. undulata. Under all future climatic circumstances, the extremely appropriate area for T. undulata was anticipated to expand, whereas the unsuitable zones would all shrink. The research would be significant for the further development of T. undulata management and conservation techniques.

Wild edible food plants (WFPs) are valuable resources in the traditional food systems of many local cultures worldwide, particularly in underdeveloped regions. Understanding patterns of food preferences requires conducting cross-cultural food studies among various ethnic groups in a specific area. In this context, the current study aimed to record WFP use among five ethnic groups in Punjab, Pakistan, by interviewing 175 informants selected through snowball sampling. The indicator food species for different ethnic groups were calculated using indicator analysis based on the percentage of citations. A total of 71 wild food plants (WFPs) belonging to 57 genera and 27 families were observed in the study area. A high proportion of these wild food plants (WFPs) belonged to Fabaceae with eleven species (15%), followed by Moraceae with seven species (9%). Fruits were most widely used (43%), followed by leaves (19%), and shoots (16%). The majority (35 species, 49%) of plants of WFPs were eaten as cooked vegetables. A cross-cultural comparison revealed that four species overlapped among five ethnic groups (Arain, Jutt, Rajpot, Mewati, and Dogar). The Arain ethnic group gathered and consumed a remarkable number of wild plants (35 species), possibly due to a special connection with the general abundance of the local flora, and being close to nature by adopting professions more allied to WFPs in the study area. The analysis of indicator species revealed distinct significant indicator values (p ≤ 0.05) between the main food species among the various ethnic groups. Amaranthus viridis was a common indicator of food in all five ethnic groups, while Ziziphus nammularia was a common indicator food plant of the Mewati, Rajpot, and Jutt ethnic groups; these plants are important in local diets, especially during times of food scarcity brought on by disease or drought. In addition, the current study reports 20 WFPs that have been rarely documented as human food in Pakistan’s ethnobotanical literature. Future development plans should consider biocultural heritage and pay appropriate attention to local ecological knowledge, dynamics, and historical exchanges of traditional food systems.
