^In fact, Berlin Tierpark is going to work together with the European breeding program (EEP) in the future. So they will just breed with the sub species from Sumatra.
Besides that, Knieriem presented some first projects that are to be implemented in 2015 and 2016 with the already secured funds from the senate (5 mio) and the Klassenlotterie (4 mio):
The Brehm building is going to be further modernized and restructured for 2.2 mio + 4 mio. The new theme for the building will be "Islands of South East Asia" and the present inside halls will get largely extended as will the corresponding outside enclosures which in fact will be merged into one massive enclusure for the tiger sub species from Sumatra. The inside and outside boxes will be merged as well and apparently the inside boxes will
not be open for the public any more. At the same time many species are to leave the house. In German zoo forums there are speculations on which of the species are goin to stay. Given the new theme, clouded leopards and still more so the leopard subspecies from Java seem obvious cases. More than that, the present bird boxes will not Show up in the new scheme. There are going to be some (presumably far larger!) boxes with reptiles (and perhaps amphibian or even invertebrate species like insects) from the region in front of the large hidden inside boxes of the carnivores. Last but nor least, the freshly re-opened tropical hall will be remodelled so it can house comodo dragons and one crocodile species. And the plans also indicate that the sun bears may get an exclosure right next to the Brehm building in the future.
The remaining 2.8 mio are going to be invested into the pre-existing and an entirely new playground area (1.6 mio), the old show arena (450k), new trains (250k) and some more or less cosmetic improvements of the entrance area and other areas of the parc.
The detailled plans (in German) are available via PDF (around 13.6 MB):

The still more detailled plan is still due for the end of the year.
