E. PROVISIONAL TABLE OF LANDSCAPE ASPECTS AND LIFE 



ZONE EQUIVALENTS 



By E. a. Goldman 



Mangrove Swamps (Tropical Zone as 

 a whole, but as mangrove swamps are 

 not dependent upon rainfall, they occur 

 within the arid or humid divisions of 

 the Lower Tropical section). 



Flood Plain Forest (low altitudes) 



— Lower Tropical Zone. 

 Luxuriant Tropical Rain Forest — 



Humid Lower Tropical Zone. 

 Drier Tropical Rain Forest — Humid 



Lower Tropical Zone. 

 Montane or Cloud Forest — Humid 



Upper Tropical Zone. It includes 



conifers and oaks in Central 



America. 

 Subalpine Evergreen Forest — 



Temperate Zone. (In Central 



America.) 



Ecuador and British Honduras, rang- 

 ing in altitudes from 6000 to 7000 ft. in 

 the former country and to 1000 to 4000 

 ft. in the latter. 



The areas in British Honduras ex- 

 tending from 1000 to 4000 ft. altitude 

 would be within the Lower Tropical 

 Zone, associated with an immense num- 

 ber of tropical species. Areas at 6000 

 to 7000 ft. altitude in Ecuador would 



probably be assigned to Sub-tropical 

 or Upper Tropical. 



Partially Deciduous Forest — Arid 

 Lower Tropical Zone. 



Deciduous Thorn Forest — Arid 

 Lower Tropical Zone. In Mexico 

 and in Panama this can not satis- 

 factorily be separated from the 

 preceding, as the regions are 

 coastal plains crossed by streams; 

 and along the streams the vege- 

 tation may be only partially 

 deciduous, or near the water line 

 evergreen, while it is completely 

 deciduous away from the water. 



(Shrub) Desert — Sonora and Lower 

 California. Lower Austral Zone. 



Semi Desert — Lower Austral Zone. 



Extreme Desert — Lower Austral 

 Zone. Desert District Vizcaino. 



Gallery Savanna — Arid Lower Trop- 

 ical Zone. A mixture of mon- 

 soon forest and savanna. Arid 

 sometimes corresponds to the 

 Lower Tropical Zone. 



Grassland, Dry Grassland — Arid 

 Lower Tropical Zone. 



Andine bushland Paramillos — 

 Paramo Zone.
