Mukuvisi Woodland, located within the precincts of Harare urban area, Zimbabwe, suffers from high illegal wood utilization pressure stemming from the need to fulfill alternative energy demands created by persistent electricity shortages and an unstable economic environment, particularly between 2000 and 2008. This results in a continuous flux of vegetation and a disturbed animal habitat driven mainly by anthropogenic activities. Due to the heterogeneity in vegetation utilisation trends, we used the stratified systematic random sampling technique, where the site was divided into two strata, central and boundary. Twelve 30 × 20 m permanent plots were established in which species name, species diversity, height, basal area, plant status, fire evidence, number of stems and saplings were recorded and assessed in April and May 2012. A total of 968 woody plants were assessed representing 47 woody plant species. All woody vegetation variables recorded and assessed showed no significant difference (P > 0.05) between the two strata, i.e., central and boundary, in Mukuvisi Woodland, except sapling density (P = 0.022). Principal Component Analysis indicated evidence of fire impacts on vegetation structure. The study concludes that illegal wood harvesting in Mukuvisi Woodland has not yet reached alarming proportions and can be contained. The study recommends collaborative arrangements with key stakeholders, promotion of the use of alternative energy sources and increased environmental education and awareness campaigns.展开更多

Therefore, this study investigated the effects of processed kote on the activities of alkaline phosphatase (ALP), aspartate aminotransferase (AST) and alanine aminotransferase (ALT) in selected tissues of weaned male albino rats using standard methods. Chemical analyses were carried out on processed fillet, skin, head & bone (SHB) diets under standard conditions. 40 male rats (40.76 ± 2.42 g) were fed with processed fillet or SHB diets for 14 days to assay for the activities of ALP in harvested samples of brain, liver, kidney, heart, stomach, small intestine and spleen;ALT and AST in the liver and heart. All data were subjected to analysis of variance by Duncan’s multiple range test and considered significant at a minimum of p < 0.05. Levels of ALP & AST in the liver, heart, kidney and brain were reduced (p < 0.05) in rats fed on test diets compared with the controls, but within accepted limit. The level of ALT in the kidney, stomach and small intestine were elevated (p < 0.05) compared to the controls, but within the accepted limit. In conclusion, coal smoked fillet and SHB greatly improved healthy growth of the rats, followed by the wood smoked and poached diets. Results suggested that processed kote SHB could be a veritable source of valuable nutrients for human food and animal feed.展开更多

The threats to wildebeest are poaching and drought while to lion are retaliatory killing and drought. The system is found in the Serengeti ecosystem. Optimal control theory is applied to investigate optimal strategies for controlling the threats in the system where anti-poaching patrols are used for poaching, construction of strong bomas for retaliatory killing and construction of dams for drought control. The possible impact of using a combination of the three controls either one at a time or two at a time on the threats facing the system is also examined. We observe that the best result is achieved by using all controls at the same time, where a combined approach in tackling threats to yield optimal results is a good approach in the management of wildlife populations.展开更多

The results indicated that the main causes of poaching and other illegal activities are associated with poverty, ignorance and culture and commercial purposes. The results further illustrated that poaching cases decreased in the Volcanoes National Park where, from 2018, the snares removed from the park reduced from above 1000 to 600 snares. In the same year, only 3 poachers from Kinigi and Shingiro Sectors were arrested. The findings illustrated that introducing of revenue sharing scheme where, 10% of the park’s revenues are shared to the local communities living adjacent to the park, and constructing a buffalo wall stone around the Volcanoes National Park are of the important measures which contributed to solve completely the problems of poaching and human-wildlife conflicts in the volcanic area. However, some respondents reported that the construction of buffalo wall did not prevent animal from escaping the park, they have proposed the construction of strong fence such as electrically fenced wall.展开更多

Despite the interventions from government and Non Governmental Organization to reduce or divert the attention of rural people from the wild by providing alternative livelihood, the level of hunting either remains the same or kept on increasing. However, there is need to categorize and understand the types of hunters in different locality for better design and management of whatever alternative to be provided. The study assessed hunters’ types and their income made from hunting in Afi, Mbe and the Okwango Division of the National park and the rate of poaching activities. The snowball sampling was adopted for gathering data. A descriptive and inferential statistical tool was used to analyze the data collected. The respondents were interviewed with a view to obtaining information on the regularity of their hunting activities, the income made per month and reasons why they hunt and also their views on best alternative. Results revealed that majority of the respondent fall within the age of less than or equal to 40 years with primary and secondary school qualification in which are married with 3 - 12 children. Consequent to this fact hunting activities is effective and prevailing. It further revealed that despite numerous conservation efforts in these areas, poaching activities still prevail owing to the fact that the income made from poaching is much better than the alternative provided for hunters. Furthermore, the assessment also revealed that there are different types of hunters and this makes their income varies greatly. Thus, there are fulltime or core hunters (36.9%), occasional hunters (58.3%), Holiday hunters (2.9%) and social hunters (1.9%). It is therefore paramount to have a better view and understanding of the target group (Poachers) for better alternative and implementation.展开更多
