The corrals and the old present buildings, they are a reflection of the life of the sabanero bajureño and they constitute a very important element in the cultural heritage of the old one Guanacaste.

Green stick is one of the places of greater ecological diversity of the country; approximately they exist 15 hábitats that are created for the topography, the conditions edáficas, including the drainage, the high current of the rivers and the effect of the tides.

Among these habitats they are found lagoons and freshwater and brackish swamps, the high grass with mangrove balance, the mangrove swamps, the pasturelands with chumico of stick or raspaguacal, the forests achaparrados of coastal fishing, the mixed forests deciduos of woodlands, the forests flooded and the forests always green.

One of the species more conspicuous and that gives name al place is the Palo Verde, a bush of leaves, branches and part of the trunk of light green color, that is found so much in the swamps as in other habitats.  Among the largest trees they are the espavel, the ciba, the pochote, the ron-ron, the cibo potbellied, the gayabón, the javillo, the cocobolo, the medlar and the Panama.  In the swamps species of aquatic plants can be observed like the tifa, the trista, the grass gamalote and the platanilla.
