I do think when it comes to endangered species, there’s also the unspoken element of speciesism in that some animals get saved because they’re considered cute, charismatic or well-favoured among humans and sometimes there’s a tendency to ignore animals that are even more endangered. The Ethiopian wolf population has declined significantly and down to the hundreds so there’s going to be a loss of genetic diversity but there are millions of dogs out there and most of them are mongrels so genetically and numerically speaking, they’re doing fine.
In fact, dogs are the third worst invasive species and if invasive species do outcompete native wildlife (the Ethiopian wolf’s only found in Ethiopia but dogs are all over Africa), then this has dire consequences for conserving Ethiopian wolves at all. Dogs are invasive in that not only do they hunt endangered species and risk endangered several others (African striped weasels in South Africa, Barbary macaques in Morocco and vervet monkeys in Uganda) but also spread diseases that kill other animals (lions and hyenas in Tanzania). This makes the situation of the Ethiopian wolves even more precarious.
As for striped and spotted hyenas, these two are nearly universally linked to witchcraft throughout Africa and South Asia that impedes whatever attempts at conserving their populations. Dogs and cats are also linked to witchcraft in Africa but only to a degree in tandem depending on the country and ethnicity (cats are linked to witchcraft in Southern Nigeria but tolerated and owned in Northern Nigeria due to religious differences), though many cats and dogs are owned in several African countries sometimes for practical purposes like pest control and some pest animals turn out to be endangered species so this complicates matter.
To put it this way, cats were brought to Cyprus for pest control this had noble intentions but who knows if a certain snake species went extinct because of that. Likewise with dogs, they could also be brought in for pest control but also risk rendering another species extinct at their expense. Dogs are beloved, certain snake species aren’t even if they’re more ecologically innocent in that they never become invasive and are relentlessly persecuted by humans. So there’s a better argument for speciesism, especially if some snakes have a worse reputation than dogs do.
The same could be said about amphibians, where some of them do inspire revulsion (as my father put it) and that complicates any attempts at conserving their populations when thought about this way. The mascot of World Wide Fund is a panda, not an endangered toad. That shows you the power of the charismatic megafauna, which can be detrimental to less cute species but there are attempts at addressing this when it comes to the Ugly Animal Preservation Society.
To summarise, some animals get prioritised not just for their closeness to humans but also their cuteness whereas others are despised for being pests even if they’re highly endangered and some are stigmatised for it, which complicates conservation efforts.
