"Terraforms" combined natural and manufactured materials in large-scale wall-mounted constructions. Ihor Holubizky wrote of Terraforms in the exhibition "Nature the Metaphorical Instrument" at the Art Gallery of Hamilton:

Jim Reid's painting is connected to the 19th century landscape painting tradition. At the same time it indicates the profound shift, which has taken place in our relationship with nature and the possibilities of a spiritual resonance. Reid works outside on large plywood sheets, and most recently has incorporated castings of the Canadian Shield and Niagara Escarpment. Rather than being satisfied with a transcription of the ground he incorporates natural and man-made materials in a hybrid amalgam where toxic material and waste combine to create new typography. The resulting work suggests growth (the implicit cycle of nature) and decay (also expressed in the unstable nature of the material itself). Reid's landscape is a means of mapping a surface in a poetic fashion."

The series was documented in the catalogue "Jim Reid - Terraforms" written by Ihor Holubizky, published in 1999 by The Art Gallery of Peterborough.
