This has been divided (loosely) into 4 habitats, so with a little bit of finagling (each band contains some element that extends past the top into the next one) you could stitch each habitat as a separate piece.
The model is stitched on 40 count "Khaky" linen from xJudesigns. Stitch count is 257 x 321.
