What irritated me was the term "tons of species", giving at least me the impression of a kind of attracitivity importance. If not: Sorry for misunderstanding.
However, again, it depends where those native fauna will be placed and in which context. Just put threatened local iberian fauna somewhere within the park doesn't support the understanding of natural connections of Joe Common and so reduce the educative value.
Looking at "proper materials" and "proper environment": Agree in general, those things can help. But they are not a miracle cure. You can make people learn about local wildlife (or wildlife in general) only if they want.
And speaking about the setup of zones at Bioparc Valencia, one of the zones I miss is the arid/mediterranean mountain range (that also has a huge intersection of Iberian and African species).
This has turned into a fascinating discourse that I feel does transcend just the Bioparco Valencia thread. I would say there is this case to be made for all Iberian Peninsula zoo collections where a local native species. component is relevant both for wonder over nature as well as our connectedness and connection to local flora and fauna.
TBH: I would go so far as to contend that a native species connection and public awareness building about local fauna and flora and the level of threat towards our living environment locally where their is a huge human footprint. You can do this both for the serious zoo visitor as well as the recreational "have a great day out in the zoo" visiting general public. If I only look at Dutch zoo community ..., some zoos do have this native species relevance and public awareness building both by their zoo animal collection with a native species connection or in the wider sense promoting how local flora and fauna are represented in situ around the zoo and outside the animal enclosures ...!!!!
What I would hope for Bioparco Valencia is that their focus will be Eurafrican ..., where probably for other regions there is more an Eurasian focus for the zoo animal collection and curatorial management. Recent moves with addax and Mhorr gazelle entering the animal collection and the need for a Mediterranean / Ibero-Maghrebi connection to North Africa and its flora and fauna.
I would definetely like to see more mountain range fauna like Pyrenean chamois, true subspecies Barbary sheep and Iberian ibex as well as Spanish and Barbary red deer, various Dorcas gazelle subspecies, Cuvier's and slender-horned gazelle as well as Mhorr dama plus various other North African and Ibero fauna from both Carnivora and other mammalian species plus assorted herps, fish (also freshwater!!!) and invertebrates / insects et cetera from native species.
EXAMPLE Iberian ibex Capra pyrenaica:
of which only 2 subspecies out of the former 4 extant taxa are surviving in the wild and not extinct - read Pyrenean ibex (the IUCN now qualifies them as Iberian wild goat Capra pyrenaica):
1.) Capra pyrenaica victoriae - Sierra de Gredos (central Iberian mountains) and reintroduced Val d'Aran, Batuecos, Montserat and along the French Pyrenees side -
2. Capra pyrenaica hispanica - arc of mountains along the Mediterranean coast from Cadiz to the Pyrenees (an escaped population in Serra de Montgri) -
and the 2 extinct subspecies
3. Capra pyrenaica lusitanica - northern Portugal and gone extinct during the 19th century and
4. Capra pyrenaica pyrenaica, the nominate form - originally occuring across the entire Pyrenees (Spain - France) and lastly disappeared from Ordesa NP and - aptly named - Monte Perdido NP in 2000! -.
The reintroductions both planned and accidental started during the 1990's when a population of hispanica escaped from an exclosure into the Pyrenees. Well after extinction of the subspecies pyrenaica both French (2014 - French Pyrenees) and Spain (Catalunya) started reintroducing populations of the victoriae subspecies.
