 1.0 ha in size, included a house site, and are used to grow fruits and vegetables for 

 commercial purposes on a full-time basis. All of the plots were adjacent to each other 

 in the corridor along Route 307, between the village of Uh-May and the turn-off to X- 

 Hazil Sur. 



Two, the category identified as "Early Secondary Forest" (huamiles and acahuales) 

 was composed of regrowth areas on sites that had repeatedly been used as gardens 

 during the past 25-50 y. This category also included cattle corrals and pastures as 

 these areas had undergone the same clearing/burning process used to make gardens. 

 In Early Secondary Forest, the stem density of trees and herbaceous plants was 

 greater than in Late Secondary Forest (see below), while the basal area was less than 

 in Late Secondary Forest (Barrera de Jorgenson, 1993). Early Secondary Forest areas 

 generally were located near roads and trails, but tended to be at greater distances from 

 the village than were the plots & gardens. Left undisturbed. Early Secondary Forest 

 eventually becomes Late Secondary Forest through the process of succession. 



Three, the category identified as "Late Secondary Forest" was composed primarily of 

 low- and medium-height semi-evergreen forest (jnonte alto and monte bajo), but also 

 included sinkholes (cenotes), ponds (bajos and lagunas), and seasonal wetlands 

 (sabanas). The forest in this category had not been used as gardens for at least 50-75 

 y (if ever at all), according to the oldest residents of X-Hazil Sur. In Late Secondary 

 Forest, the stem density of trees and herbaceous plants was less than in Early 

 Secondary Forest, while the basal area was greater than in Early Secondary Forest 

 (Barrera de Jorgenson, 1993). Ponds, sinkholes, and seasonal wetlands were included 

 in this category because they were quite small, not used for gardens, and widely
