No optimism no hope and then they wonder why no one cares or are to depressed to show interest. How about Delilah and the others at the way kambas sanctuary, or a past success the white rhino had only 50 in the past century and now it's growing to 17 to 20.000. The animation was great and the information on spot but the positive side a big Fu.
The Sumatran rhino breeds a lot less than white rhinos and will only have a calf every 3+ years, and since hardly any have been born in captivity there is little known about how to breed them. Anyway some positive news is that none have been poached since 2006 and all known rhinos are in protected areas so hopefully one day they will not be endangered
@@germansojopagan7381 it seems reproductive for sumatran rhino is more complicated. They naturally are infertile after a while. It seems this is because sumatran rhino as descendant of whooly mammoth who were already bottlenecked long time ago. After the ice age collapse as they separated in islands, so most are already not genetically diverse. I read somewhere the way kambas said they actually breed (have sex) a lot but the female just not getting pregnant especially the older one as they naturally develop tumor in the uterus. Not helping that most are related too. That is why scientist even had the crazy idea of mixing subspecies from borneo. They did capture a female borneon but she lives alone in the sanctuary on another island. There seems to be no progress of inseminating her with way kambas sperms though.
@@germansojopagan7381 Optimism is cute and all, but that can't override the ugly reality. Sumatran rhinos were dealt a bad hand; they are very slow breeders, their habitat is becoming increasingly fragmented, they have lost a lot of genetic diversity and they notoriously don't do well in captivity, and China is still putting a heavy bounty on rhinos in general. That's a hell of a lot going AGAINST them. This leaves us with basically no solid option for preserving the species. Which unfortunately means that extinction is the only option.
@@daliborjovanovic510 the leseur ecosystem in sumatra is one of the only places where the population is showing increase and is a stronghold for these creatures, the iucn has to focus on the rise just as much as the fall theres still a chance.
Excellent. Thank you Mongabay.
We don't need horns tusk or fur we need animals
#You made city list population big mistake nothing is right.
