Green Castle Estate is a 650 ha (1,600-ac) property consisting of diverse terrestrial and marine ecosystems. The elevation ranges from sea level to approximately 150 m (500 ft). More than 425 m (4,000 ft) of coastline varies from beach to rocky shores, with near-shore reefs. The land forms include a cleared plain of approximately 200 ha (500 ac) and 450 ha (1,100 ac) of deeply contoured, wooded hillsides and valleys. There are several streams that course through the property, one of which has been dammed to form a 3 ha (7 –ac) reservoir for irrigation with a maximum depth of 6 m (20 ft). Several natural freshwater and brackish ponds support emergent vegetation and mangroves. Overall, the site has a long history of mixed agriculture use; current and future uses include active agriculture, conservation for eco-tourism, habitat preservation and watershed protection.

Agricultural production at Green Castle is done by JamOrganiX. They operate on approximately 300 ha (700 ac) of the property. Certified organic tree crops (coconuts, pimento, cocoa, and limes) are grown on hillside patches within secondary growth limestone forests. In addition to the tree crops, wild populations of guava, sweetsop, soursop, otahiti apple, avocado, breadfruit, sapodilla, jackfruit and noni are found on the Estate.

Livestock production occurs within the agricultural areas, plus on an additional 120 ha (300 ac) used to support 250 head of tropical beef cattle (Brahmin, Jamaican Red Poll, and Jamaican Black Poll). The Livestock operation is run by Eastern Livestock Development Association.

Horticultural production of orchids is run by GC Orchids, and occurs in a controlled environment within four growing houses. There are three 4,000 m² (1-ac) and one 2,000 m² (½-ac) metal-framed, plastic-roofed, screen-sided houses supporting a variety of plants that produce cut and potted products.

The remaining 150 ha (600 ac) of undeveloped ecosystems support a wide variety of lowland tropical vegetation, insects, and birds (100 hundred bird species have been sighted at Green Castle, including 19 of Jamaica’s 26 endemic species).
