Using Trophy Hunting to Save Wildlife Foraging Resources: A Case Study from Moyowosi-Kigosi Game Reserves, Tanzania

Globally, the role of trophy hunting in wildlife conservation has been a topic of much debate. While various studies have focused on the financial contribution of trophy hunting towards wildlife conservation, little is known about whether hunting activities can protect wildlife forage resources. We examined the effect of illegal livestock grazing on wildlife habitat in operational and non-operational wildlife hunting blocks in Moyowosi-Kigosi Game Reserves (MKGR), Tanzania. We assessed whether the physical presence of hunting activities lowered illegal grazing and, thus, led to higher vegetation quality. We compared 324 samples of above-ground biomass (AGB) and grass cover between control (0.0007 cattle ha−1), moderately (0.02 cattle ha−1), and intensively (0.05 to 0.1 cattle ha−1) grazed hunting blocks. Likewise, we assessed soil infiltration, soil penetration, soil organic carbon (SOC), and soil Nitrogen, Phosphorus, and Potassium (N-P-K) across grazing intensity. Illegal grazing decreased AGB by 55%, grass cover by 36%, soil penetration by 46%, and infiltration rate by 63% compared to the control blocks. Illegal grazing further lowered SOC by 28% (F2,33 = 8, p < 0.002) but increased soil N by 50% (F2,33 = 32.2, p < 0.001) and soil K by 56% (H (2) = 23.9, p < 0.001), while soil P remained stable. We further examined if Hunting Company (HC) complements anti-poaching efforts in the Game Reserves (GR). We found that HC contributes an average of 347 worker-days−1 for patrol efforts, which is 49% more than the patrol efforts conducted by the GR. However, patrol success is higher for GR than HC (F1,21 = 116, p < 0.001), due to constant surveillance by HC, illegal herders avoided invading their hunting blocks. We conclude that illegal grazing severely reduced vegetation and soil quality in MKGR. We further claim that trophy hunting contributes directly to wildlife habitat preservation by deploying constant surveillance and preventing illegal grazing. We propose maintaining trophy hunting as an essential ecological tool in wildlife conservation.

Aims: In this study, we assessed the effect of physicochemical properties of soils from different land use systems on the population of Actinomycetes. Study Design: A cross sectional survey design in line transect sampling was used in collection of samples from land use systems. A 4×6×3 factorial experiments laid in completely randomized design was used in determining Actinomycetes population in land use system and media type culture. Place and Duration of Study: The study was conducted in Meru south sub-county, Kenya, between January 2019 and July 2019. Methodology: Cultural growth of Actinomycetes was determined using four different media type culture. The physicochemical properties of soil were evaluated using standard laboratory methods. The data obtained were analyzed using analysis of variance and significantly means were separated using Least Significance Difference at α = 0.05 in SAS version 9.4. Correlation analysis was used to determine the relationship between soil physicochemical properties and Actinomycetes population. Actinomycetes population varied significantly (p < 0.05) among the different land use systems. Results: The study's findings revealed significant variations (p < 0.05) in Actinomycetes populations across the different land use systems. The type of media used significantly influenced the growth and proliferation of Actinomycetes colonies, with the Starch casein medium exhibiting the highest number of colonies (3.4 × 105 cfu/ml of soil sample) and the modified Luria Bertani (M1) medium showing the lowest (1.7 × 105 cfu/ml). The Actinomycetes populations demonstrated significant variations (p < 0.05) among the different land use systems. Correlation analysis revealed a moderate positive correlation (r = 0.63407; p < 0.0001) between Actinomycetes population and soil pH, as well as weaker positive correlations (r = 0.3375; p = 0.012) between soil moisture content and Actinomycetes population, and available potassium and Actinomycetes load (r = 0.31483; p < 0.0001). Conclusion: The study concludes that the population of Actinomycetes was affected by soil physicochemical properties and consequently land uses.

Objective: To evaluate the physico-chemical composition and the presence of potentially useful bacterial to be used as biofertilizer in the excreta of Dendrocygna javanica and Anas platyrhynchos domesticus. Methodology: The microbial culture and physico-chemical analysis was done at the department of botany, Gauhati university. Six different media were taken for microbial growth. After 24 hours of observation microbial colonies were counted and recorded. For physico-chemical analysis four parameters were taken viz., organic carbon, ash content, moisture content and pH, as those four components are essential for soil and plant growth. Findings: The excreta of Dendrocygna javanica show abundant growth of nitrogen fixing bacteria, less fastidious bacteria, yeast, moulds, Acetenomycetes and phosphate solubilizing bacteria. Physico chemical analysis have also shown favourable result against Dendrocygna javanica, indicating the biofertilizer nature of its excreta. Novelty: There is limited literature available concerning the microbial profile and physico chemical analysis of faeces of Dendrocygna javanica and Anas platyrhynchos domesticus. Infect, the present study provided the guidance for culturing and conserving these two duck species since these have a good possibility as bio fertilizers.
