British Guiana Recent work in timber inventory from aerial photographs in British Guiana has given some of the most encouraging results yet re- ported from mixed tropical forests. More than 25 different forest associations have been dis- tinguished on the photos, and estimates of greenheart {Ocotea rodiaei [Rob. Schomb.] Mez) volume from the pictures have shown excellent correlation with available. ictual volumes Natural regeneration of greenheart fol- lowing cutting has been good. In the area visited greenheart appears to be on the way toward making up a higher proportion of the stand in the cutover areas than it was in the original forest. Pine plantings have been made in the last five years. Growth is better on the brown sandy loams, but even on the white sands which support a very inferior native vegetation pines are promising; slash pine is off to a faster start than Honduras pine. The most important problems to date are the high cost of site preparation and the coushi (Atta spp.) ants which defoliate the pines, especially after they have been cleaned of competing weeds and brush. The ants are poisoned in their. Figure 4. — Prefabricated house.
