The region contain the largest part of the Selva Zoque (Zoque Forest) ecological region, that extends into adjacent Veracruz and Chiapas states.  It is an area of significant ecological importance, including the largest intact tropical cloud forest in Central America. It also has lowland tropical rainforests, tropical dry forests, Sierra Madre de Oaxaca pine-oak forests and Sierra Madre del Sur pine-oak forests, and Central American montane forests. The forest is also home to 300 species of native orchids, representing 27% of known Mexican orchid species and 60% of recorded Mexican orchid genera. 
The region has cement and lime plants. The main industry is the Pemex oil refinery in the port of Salina Cruz, the largest city in Istmo de Tehuantepec, located on the Pacific coast at the Gulf of Tehuantepec. The isthmus has extensive livestock production operations. Crops include sesame, coffee, rice, sorghum, pineapple, banana, coconut, melon, and sugarcane. Fishing cooperatives harvest shrimp and other seafood from the Pacific.
The government has plans to develop the trans-Isthmus of Tehuantepec corridor, including improving transportation routes, developing an industrial zone along the highway, and expanding the petroleum and petrochemical industries in Salina Cruz. Other plans include creating coffee plantations and cattle corridors; expanding production of beans, maize, and chili; and exploiting the bio-genetic resources of native medicinal plants.
