"The new zoo will be home to almost 1,000 animals from around the world, and out of those, there will be more than 350 species of rare and endangered animals"
The eternal species or individual animals question. Articles about zoos always get those mixed up or use wording that allows for free interpretation. Assuming they mean both (1,000 individuals, 350 rare species [+common species]), there'll be very few individuals of each species and likely a lot of singles. I hope that won't be the case. Assuming they ment individuals in both (1,000 individuals, incl. 350 individuals belonging to rare species), it'll be decent numbers for a safari park that usually mostly keep mammals, but few compared to a normal zoo. If they ment species in both (1,000 species, incl. 350 rare species), it would be one of the mega-diverse zoos in the world. Not quite Berlin (boosted by its aquarium), but more than e.g. San Diego.
Anyhow, 119 ha (492 acres) means they won't run out of space anytime soon. If they, as suggested by the article, have visited zoos in Singapore, Austria, Germany and San Diego (less happy about Indonesian zoos) that's certainly a good basis for making a good zoo.
It'll be interesting to see how this turns out.
