Estimating the population parameters, performance and factors that influence reproduction from long-term, individual-based monitoring data is the gold standard for effective wildlife management and conservation. Yet this information is often difficult and costly to collect or inaccessible to managers. We synthesized a 20-year set of individual-based monitoring data from a subset of black rhinoceros Diceros bicornis subpopulations across a range of environmental conditions in Namibia. Our findings demonstrate that despite the relatively arid landscape in Namibia, the black rhinoceros metapopulation is performing well, measured by age at first reproduction, inter-birth interval, population growth and survivorship. Information-theoretic modelling revealed that a univariate model including normalized differential vegetative index had a greater influence upon age at first reproduction than population density. The inter-birth interval model set identified cumulative rainfall during the 15 months prior to the birth month as the top model, although the mean normalized differential vegetative index during the inter-birth interval was comparable. There was little evidence for density-dependence effects on reproduction. These findings suggest that although browse quality could have a greater impact on parameters spanning multiple years, shorter-term parameters could be more influenced by rainfall. Our analysis also revealed a synchronous pattern of conceptions occurring in the rainy season. Our study provides a set of population parameter estimates for Namibian black rhinoceros subpopulations and preliminary insights on factors driving their reproduction. These expand our collective knowledge of global black rhinoceros population dynamics and improve our confidence and capability to adaptively manage the black rhinoceros metapopulation of Namibia.

Relatively few studies have examined how the degree of involvement of local communities in nature‐based tourism, and the benefits that are generated for them, impact the choices that tourists make when visiting developing countries. We surveyed over 400 visitors in multiple locations in Namibia, using a discrete choice experiment to elicit preferences for attributes reflecting tracking safaris of the critically endangered, desert‐adapted black rhinoceros (Diceros bicornis bicornis) in the northwest of the country. Attributes included those related to local community involvement and the benefits they receive from tourism, as well as the reinvestment of tourism profits back into rhino conservation, and the wildlife likely to be seen on safari. Using a latent class model that assigned tourists to market segments based on the observed pattern of responses in the choice experiment, we find that respondents can be divided into four classes that reflect differences in tourism preferences and their own demographics and experiences. While responses to attributes varied across classes, respondents were consistent in demonstrating a strong preference for the largest share of profits being returned to the local community, and were willing to pay an additional $43–670 to ensure this happens. Respondents in the four classes differed in their views toward the financing of rhino conservation and the participation of community trackers in rhino safaris, although those respondents in the class most interested in rhino tracking safaris were willing to pay an additional $34 per trip for tracker involvement. Our results demonstrate the value of assessing heterogeneity in tourists' preferences for wildlife experiences, and suggest that appropriate pricing and marketing may result in "triple bottom line" gains for nature‐based tourism.

Wildlife-based tourism is widely promoted as a conservation tool, yet controversy surrounds its net contributions. Procedural problems are under-appreciated and originate from an under-attention to people: their interactions, values at play, and matters of special, shared, and common interests. We offer a case in Namibia of black rhinoceros conservation tourism that attended simultaneously and systematically to the inter-related ecological and social processes involved. We demonstrate how an understanding of social context and the decision making process developed, how outcomes were evaluated and synthesized lessons into prototypic elements as a pneumonic that we term the 'ACE approach': (1) establish an Arena for inclusive, open debate; (2) identify and use Conservation-oriented messaging ; (3) adopt participatory Evidence-based management for action, feedback, and learning. • Wildlife-based tourism is often promoted as a conservation tool. • Understanding procedural problems may improve conservation outcomes. • A 15-year old black rhinoceros conservation tourism cooperative case was examined. • The social context and decision making process is described and assessed. • Lessons were synthesized into prototypic elements for sharing and learning.

In the last decade, poaching of high-profile wildlife species has increased across Africa, particularly threatening the viability of rhinoceros populations. Protection efforts and anti-poaching measures have increased across the continent, but a lack of research on the motivations driving the recruitment of local people by poaching syndicates may limit successful law enforcement. We explore the societal drivers and personal motivations behind individuals' involvement in poaching syndicates in Namibia and how this process is perceived at different levels of decision-making. There was a general consensus across all informant populations that wildlife crime syndicates are divided into five tiers of engagement. Poachers, the lowest tier, are typically recruited by a second tier of local business people via a cycle of dependency and debt. Further, although anti-poaching efforts are generally aimed at apprehending individuals at the lowest tier, the dependency mechanism used by local recruiters supplies syndicates with a consistent source of recruits. We also identified a misalignment of perceptions between local people and socially distant conservation practitioners regarding the personal motivations and societal drivers of commercial poaching. We urge conservation practitioners to invest in developing a more contextual understanding of local perceptions and perspectives prior to establishing rhinoceros protection measures. Such contextual information is critical to ensuring that limited conservation resources are used effectively to achieve the greatest positive impact for both people and rhinoceros.
