Two vegetation associations derived from limestone soils have been mapped in this sub-tropical moist forest. THese associations are characteristic of the hillsides and tops of the limestone or haystack hills which are oriented northeast to southwest. Porous limestone soils with excessive drainage creates a xeric environment on the tops of the haystack hills; however, the protected areas between the hills are more humid. The most common tree species in the moist limestone forest include: úcar (Bucida buceras), almacigo (Bursera simaruba) and uvilla (Coccoloba diversifolia). A large portion of the Guajataca forest has been previously cultivated or disturbed and is now planted to kadam, maria and mahoe.
