Numbers of animals in captivity in Europe

According to what I have researched in the last 3 years, from ISIS, EAZA breeding programes, SSP (for USA), studbooks (regional and international), Zootierliste, Wikipedia, some other research, I found and proposed the next demography for some captive animals in European zoos (and in USA, but I will not present the demography for USA captve animals right now, maybe in some other post). For African and Asian elephants, numbers in circuses are also shown, for other animals the numbers are just for zoos. All these animals live in aproximately 900 zoos/aquariums in Europe (both EAZA members, and non EAZA zoos).
This don't mean that the numbers are very accurate, but they represent some aproximately numbers for wich I estimated that are closest to the real numbers.

(Any corrections/additions are welcomed, please communicate your findings here to make corrections (and additions for new species))

I like seeing them as small herds, prides or groups in sumarised numbers, and love their numbers to increase (especially for those with numbers under 100), as insurance populations against extinction in the wilderness.

 

Only 90 spotted hyenas in Europe?
Quite small population for a species represented in around 40 zoos.
Same for the striped hyena, you say there are only 45 animals in European zoos,
but that is almost the number or zoos that keep them.
So do all zoos (with a very few exceptions) keep only one individual?

 

Probably you are right, as I wrote corrections and additions are welcomed. I do not have acces to ISIS right now. Zootierliste list 42 zoos who keep stripped hyenas, and yes 40 who keep spotted hyenas. I will correct numbers What you think of aproximately real number of these animals kept in European zoos, I will wrote 130 for spotted, and 90 for stripped. I know that stripped and brown hyenas are very difficult to breed in captivity, to the point that I think in USA there aren't brown hyenas any more in captivity, and with only 5-10 left in European zoos. And yes, some of theese informations are little bit outdated, since I've gethered them in 2014.

 

I corrected the number. As I wrote, some informations are from 2014 or even 2013. In the last 3 years - as I wrote !!! - in the original post.

And you can not generalise for all animal numbers that are incorrect. Of corse that they are not accurate to individual (one). But I try to represent the numbers in aproximately the real numbers.

 

Yeah, for ISIS, but I can't remmember from where I have actually record 70 or 100 Green tree monitors, in 2014 when I made my list in word. That time, I even don't knew about Zootierliste.

So can you help me, with some of your eventual findings and opinions on numbers, for every species. And please feel free to comment, criticise, as we mostly do ; but I would love to make some good list. So can you tell me first about your opinion and estimates of number of Green (Emerald) tree monitors?

 

Oh Lol , I wrote just for animals in zoos, and for elephants, also in circuses.

I would say that there are * 1000 * green tree monitors as pets, or in pet breeders. But I concentrate just on zoos, as most reliable conservation centres and responsible institutions.
In that way, for example, also the numbers of other animals will go very further, eg. for citron-crested cockatoos, I listed 100 in zoos, but as pets, probably there are more than 1,000 in all of Europe.

 

number of populations of animals in zoos in Europe continued...

Asiatic lions: 130

Fossa: 60

Blue-eyed black lemur: 35
Black lemur: 140
Alaoatran gentle lemur: 80
White-belted ruffed lemur: 50
Red-fronted lemur: 60
Red-bellied lemur: 110
Aye-aye: 18 (in USA 24, in Japan 10)
Greater bamboo lemur: 15-20
Crowned sifaka: 15-20
Pygmy slow loris: 100

Secretary bird: 70

 

What do you use as a source for your numbers as they seem quite random and the ones I know of are incorrect (by example there are 19 Aye-Aye's in Europe not 18). Also some of the others seem too low (Asian lions and Alaotrain gentle lemurs by example) or too high (blue-eyed black lemur).

 

Yeah, as I wrote corrections are welcomed. Not 18 but 19 Aye-ayes, that is yet near the accurate number.

I use EAZA yearbooks or tags for certant species, that last one dated from 2008, also I take into mind the number of holders from ZooTierliste, and regional or international studbooks who list all animals. Also some other journals like Zooaquaria from EAZA (wich are published each year season - four times a year). And before 2012, I also visited ISIS. And one research about elephants in captivity (from 1999).

About Blue-eyed lemur, actually there were 30 individuals in Europe 2008, according to EAZA Prosimian tag you can see here http://eaza.portal.isis.org/activities/cp/yearbook20072008/22_Prosimian_TAG.pdf

 

Then your sources are quite dated and so my question is why do you want to make a topic with population size guesses, because in the end you are just guessing.

 

Well it is better that having none. If I could I would make accurate estimation, but that's not possible for person like me. An enthusiastic who don't work in any zoo or zoo association.

I'd liked to see the gethered numers of animals, because I feel better when I will see aproximately how much animals are kept from particular species, as insurance population.

Plus I already mention in the first post that the numbers are not very accurate but close estimation.

 

It depends for wich species. For Aye-ayes, I just made mistake for one wrong estimated-prescribed individual, so not for all TeaLovingDave, guessing what is your proffesion, and knowing that you love to drink tea and think on small carnivores ....

 

...so how is that helping the discussion? Or your self-proclaimed goal to learn more about zoos and your discussion partners? Have you already forgotten what you were told today?

 

No I don't forget. But I am just curious. But I will not ask anymore, ok yes maybe via private messages.
