From the hillside I would see that more than half of the original forest area in the valley is in cultivation or is in the process of being cleared. To the South there is a long dry, low hill with a rather dense low forest on it. The tree to the left have been cleared most of the way along the valley which is about 1/2 - 3/4 miles wide. Near our study area the forest extends down to level ground from the hillside - on level ground the trees have been chopped down for the most part but a few remain. There are very few large trees in this valley - the largest being guanacaste trees. Bonifacio said that the common tree with oak-like leaves is the totopote - this is rather common in the area we studied today. There are several other trees - all deciduous. Areas which appear to have been previously cleared are now covered with dry lemon grass. Here and there - and especially near the streambeds, the vegetation is greener and more lush - but generally the area is much more arid in appearance. We noted no mango trees around our study area. I should judge the at one time this entire valley had a rather dense deciduous forest in it - with larger trees than there now on the hillside - since
