“…Climate change, animals and fire are some factors that affected vegetation dynamics in those ecosystems (Silori and Mishra, 2001). As forest fire could be useful or destructive to the forest, while tree species vary in their responses to forest fires.…”

The effect of forest fire on natural forest in Southern Guinea Savanna in Nigeria was investigated. The study was carried out in Oro forest reserve in Kwara State, Nigeria. The study site was located in the north-eastern and south-western portions of the reserve. In each location in the forest, one hectare (100 m × 100 m) was divided into 100 plots of 10 m × 10 m. Twenty plots were randomly selected for determining the frequency of burned trees, re-sprouted trees and the numbers of seedling/ha. Soil samples were also collected at three depths: 0 -5, 6 -10, 11 -15 and 16 -20 cm. Soil samples were taken before burning and one year after burning. The effect of fire on tree species recovery showed that regeneration of Byrsicarpus coccineus, Grewia mollis and Butyrospermum Paradoxium were very encouraging in the burned area. In contrast, Adenodolichos peniculatus, Fadogia pobegunii and Terminalia aviceniodes were very sensitive to fire as they failed to regenerate or poorly reproduced in the burned area. Fire had no effect on soil texture except 0 -5 cm. Soil pH significantly increased available phosphorus increased significantly, whereas, soil organic matter, available acidity and total nitrogen significantly decreased in the burned area. Also, metallic cations (Ca, Mg, K) and cation exchange capacity increased in the burned area. These changes were related primarily to oxidation of the organic matter layer during fire and concurrent changes in the soil environment following fire (e.g. a reduction in organic matter content of the soil, and increased soil pH).

“…The study area is located in the Nilgiri Biosphere Reserve in South India with an area of 5520 sqkm and supports largest elephant population (6000) in India (Williams et al 2020). The developmental activities in the form of the construction of series of hydroelectric power stations numbering about three in Singara, Masinagudi and Moyar around the Masinagudi village in the eastern part of Mudumalai Tiger Reserve caused rapid growth in the human population to 143% between 1961 to 1991 (Silori and Mishra, 2001). Thus assessment of HEC would support the management of elephants in these areas and con ict mitigation.…”

Human-elephant conflict (HEC) is a negative interaction between elephants and humans. HEC affects local community livelihood and the success of elephant conservation. The Asian elephant population and HEC were studied in the Niligiri Biosphere Reserve in the year 1992 (Balasubramanian et al. 1995) using this information as baseline data. We have studied HEC in the selected 14 villages located in the Moist Deciduous forest and Thorn forest areas of Mudumalai Tiger Reserve from Nov 2006 to Mar 2008, which were part of the earlier study. The data on crop species, elephant damages, protection method and land-use changes concerning HEC were collected fortnightly by direct enumeration and questionnaire survey. A total of 297 crop damage incidences were recorded. The crop-raiding pattern and the peaks in raiding are during monsoon periods were similar to the earlier study. A total of seven people were killed and six were injured by the attack of elephants in the ten years (1998 to 2008) and results in 1.3 incidences/year. The overall crop damage has declined from 2.1% in the early 1990s to 0.98%. The spatial location of HEC indicated that the mean damage percent was higher in the peripheral areas (1.51%) than in the center of the village (0.18%). There is a major shift from crops grown for food (finger millet) to commercial reasons. Multiple regression analysis revealed that the effective perimeter length (perimeter with cultivation) and total area of cultivation had a primary influence on the crop damage, followed by the area of degradation around the village and percent edible crops in the boundary. Further, logistic regression on crop-raiding incidences with the independent predictors indicated that among habitats in the MDF the crop-raiding incidences were 95% higher than that of TF. Palatable crop species plantain, paddy, finger millet and vegetable crops were 391% raided more frequently than the non-palatable species. Crops with protection methods were 22% less frequently damaged than the crops without any protection. Thus changes in the crop species, improved protection and land-use changes have reduced HEC in the adjacent areas of Mudumalai TR. The resettlement of villages from the core area of reserve in MDF would greatly reduce HEC in MTR.

“…Thapa et al [27] used livestock numbers to calculate the livestock carrying capacity of land resources in the southern mountains of Nepal. Silori et al [28] noted that the increasing number of livestock in southern India has disturbed the habitat of large mammals in the Mudumalai Wildlife Sanctuary. Zhang et al [29] used remote sensing to estimate the forage yields and livestock carrying capacities of different types of grasslands in the Three-River Source region and found that there were 6.52 million overgrazing sheep units in that region in 2010.…”

Using the Yellow-River-Source National Park (YRSNP) as a study site, an unmanned aerial vehicle (UAV) remote sensing and line transect method was used to investigate the number of wild herbivorous animals and livestock, including the kiang (Equus kiang) and Tibetan gazelle (Procapra picticaudata). A downscaling algorithm was used to generate the forage yield data in YRSNP based on a 30-m spatial resolution. On this basis, we estimated the forage–livestock balance, which included both wild animals and livestock, and analyzed the effects of functional zone planning in national parks on the forage–livestock balance in YRSNP. The results showed that the estimates of large herbivore population numbers in YRSNP based on population density in the aerial sample strips, which were compared and validated with official statistics and warm season survey results, indicated that the numbers of kiangs and Tibetan gazelles in the 2017 cold season were 12,900 and 12,100, respectively. The numbers of domestic yaks, Tibetan sheep, and horses were 53,400, 76,800, and 800, respectively, and the total number of sheep units was 353,200. The ratio of large wild herbivores and livestock sheep units was 1:5. Large wild herbivores have different preferences for functional zones, preferring ecological restoration areas consisting mainly of sparse grassland. The grazing pressure indices of the core reserve areas and ecological restoration areas were 0.168 and 0.276, respectively, indicating that these two regions still have high grazing potential. However, the grazing pressure index of the traditional utilization areas was 1.754, indicating that these grasslands are severely overloaded. After the planning and implementation of functional zones, the grazing pressure index of YRSNP was 1.967. Under this measure, the number of livestock was not reduced and the grazing pressure nearly doubled, indicating that forage–livestock conflict has become more severe in YRSNP.
