Enjo straddles the central Biedouw Valley, where the vegetation in the lower reaches transitions from fynbos to succulent Karoo veld. However, the upper reaches of the Perdeberg and Tra-Tra mountains remain characterized by fynbos, and some species typical of the Cederberg fynbos, such as the Grey-winged Francolin and Cape Sugarbird, can be found here.

The birding along the river and in the surrounding veld is characterised by typically Karoo species, such as Karoo Chat and Rufous-eared Warbler.

When the Biedouw River flows (it is seasonal, typically running from early winter to mid-summer), it supports species like the Malachite and Giant Kingfisher, while Little Rush Warbler and African Black Duck can be found in the more secluded stretches.

Common raptors include Pale Chanting Goshawk, Jackal Buzzard, and Rock Kestrel, while Verreaux’s Eagles breed on the cliffs of both mountain ranges bordering the farm. Black Harriers are occasional visitors. Spotted Eagle-Owls are common to abundant, with up to 3 or 4 pairs heard calling simultaneously around the farm house and camp site in the evenings. Cape Eagle-Owl is also a possibility, though it has only been identified by its call so far.
