“…It has been estimated that the total number of bird species being kept in cages represent up to 37% of the world’s identified species [ 5 , 10 ]. However, along with other factors including habitat fragmentation, degradation and loss; climate change; urbanization; pollution and natural disasters [ 10 – 12 ], keeping birds in captivity has led to population declines and threatened many targeted species [ 5 ]. Therefore, a wide range of measures, such as law enforcement to tackle illegal poaching and trade, setting up protected areas, restoring degraded ecosystems and controlling invasive species, have been adopted to combat these serious biodiversity concerns [ 13 , 14 ].…”

Background The Chinese Hwamei (Garrulax canorus Linnaeus, 1758) is a widely distributed species and has long been kept as a pet, especially by the ethnic communities in Southwest China. According to conservation experts’ suggestions, it has been designated as a second-level national key protected species in February, 2021 to protect this bird, indicating that keeping it at home is no longer permitted in China. However, a key factor to ensure effectiveness and success of conservation initiatives is local stakeholders’ acceptance and support. Methods Interviews and focus group discussions were used to document the policy outcomes and the views of 108 local bird-keepers in a county in Guizhou province. Results Despite awareness about the illegality of the practice, the bird was still commonly caged both in rural and urban regions. To justify their unwillingness to stop keeping these birds, the interviewees presented many arguments, such as benefits for the community members’ health, cultural heritage and contributions to local livelihoods. Fewer than 30% of the bird-keepers believed that the practice of self-keeping has reduced the wild population. Most argued the decline was mainly generated by the harvesting and keepers with monetary interests. They suggested enforcement should target those people and bird markets, as well as the harvesting methods. They also recommended restricting the number of birds allowed to be kept by one keeper, establishing protected areas and a harvesting ban period. The study participants demonstrated considerable local ecological knowledge about approaches for managing the species’ use. Conclusions Due to the benefits for the people and the bird’s large distribution, I argued that a conservation goal to lower the harvesting and keeping rates would be more appropriate than a strict ban on keeping them. Such a policy would be more feasible and culturally acceptable because it is built on keepers’ support and suggestions. It is necessary to monitor the effects of bird keeping on the wild population. Overall, this qualitative study demonstrated the advantage of factoring in local voices in conservation decisions.

“…Many factors affect the spatial distribution of roadkill. These are broadly divided into landscape features, species traits, road attributes, traffic characteristics, and temporal factors (Aquino & Nkomo, 2021). Landscape features (e.g., land cover, topography) determine the abundance of species and their movement patterns across the landscape, thereby affecting the occurrence of wildlife near the road (Plante et al., 2019).…”

Wildlife mortality risk posed by high and low traffic roads

Wildlife mortality due to collisions with vehicles is considered one of the predominant negative effects exerted by roads on many species. Reducing roadkill is therefore a major component of wildlife conservation. Roadkill is affected by various factors, including road attributes and traffic volume. It was theorized that the effect of traffic volume on roadkill probability should be unimodal. However, empirical evidence of this theory is lacking. Using a large‐scale roadkill database of eighteen wildlife species in Israel, encompassing 2,846 km of roads over a period of 10 years, we explored the effects of traffic volume and road attributes (e.g., road lighting, verge vegetation) on roadkill probability using a multivariate GLMM analysis. A unimodal effect of traffic volume was identified for the striped hyena (Hyaena hyaena), while five species demonstrated a novel quadratic U‐shaped effect (e.g., golden jackal (Canis aureus)) and four species showed a negative linear effect (e.g., wild boar (Sus scrofa)). We also identified varying effects of road attributes on roadkill. For instance, road lighting and roadside trees decreased roadkill for several species, while bus stops and concrete guardrails led to increased roadkill. The theorized unimodal effect of traffic volume may only apply to large, agile species, while the U‐shaped effect could be related to intraspecies variability in traffic avoidance behavior. Altogether, our study revealed that both high traffic and low traffic roads can pose a high mortality risk for wildlife. It is therefore important to monitor roadkill on low traffic roads and adapt road attributes where possible, to improve road design for wildlife. An effective roadkill reduction strategy can benefit from combining road design measures like reducing the use of concrete guardrails and median barriers, with mitigation measures that are suitable for low traffic roads, such as wildlife detection systems combined with driver warnings, and seasonal traffic calming.This article is protected by copyright.

“…Traffic can affect animal populations in two ways: firstly to kill the animals and secondarily, by dividing the habitat of population into fragments (Gregory et al, 2021). Roads are very important tool for movement of animals from one place to another however, they can create a lot of chances to increase the mortality rate of animals that lived around the roads (Oddone and Nkomo, 2021).…”

Wild animals are very important for our ecosystem maintenance. In the last few decades, the rate of animal’s accident on roads has increased due to heavy traffic. This research was carried out to find the reasons for road mortality of animals on Bhalwal Road, Sargodha, Punjab, Pakistan. It was noticed various animals like rats, porcupines, lizards, snakes, turtles and jackals lived in crops and trees that were found around the road and they were killed by road traffic while crossing the roads. It was seen that almost 80 to 90 % of road mortality was due to over speed driving. Moreover, the travellers were not aware of the importance of these common wildlife, so they did not bother the animals moving on the road. It was observed that most of the animals that killed on roads belonged to reptiles (Monitor Lizards’), amphibians (Frogs and Tortoise) birds (crow) and mammals (Jackals, mouse, dogs, cats and porcupines). It was concluded in the study that there is a need to highlight the importance of wild animals for the locals, travellers and also for the stakeholders that start work on mitigation strategies that help to conserve these wild animals.
