Shaldon zoo has a big car park opposite it which can be used for the zoo. It's an acre in size, but it's expanding into the adjacent woodland, not sure when this is going to be completed though.
When I went in 2007, they had Slow loris and pygmy loris, tree shrews, pygmy marmosets, gundi, ring tailed, black and white ruffed, gentle and red ruffed lemurs, red titi's, silvery marmosets, golden, pied, and golden headed lion tamarins, ocelots, yellow breasted capuchin, scarlet macaws, kookaburra, bobook owls, dusky loris, agoutis, meerkats, cusimanses, brush tailed porcupine and potoroo.
Most the enclosures were average sized, and well furnished. However the single dusky lori was in a tiny little cage behind the lemurs, and the ocelot cage is pretty pitiful.
However, I think they are mainly improving the enclosures they have by expanding into the woodland, as opposed to getting lots of new species.
