- As discussed in LHW, for
future scatterometers this requirement may be relaxed.
- ...chaco
- Chaco - Drought deciduous lowland (and submontane)
woodland. The Gran Chaco region is found in Bolivia, along the plain between
the Paraguay and Parana rivers in Paraguay, and along the Rio Paraguay in
southern Brazil. This woodland is typically multi-canopied and deciduous, with
cactus located in drier areas. There are many climatic and edaphic variations
on a local scale which are not differentiated on the map.
- ...caatinga
- Caatinga - Semi-deciduous thorn scrub with
succulents. It is found in north-eastern Brazil in areas where the climate is
subhumid to arid. It is bordered on the east by the northern variety of campos
cerrados and on the east by the coastal Atlantic forest and related degraded
formations. Climax caatinga formations are ligneous, drought-deciduous,
thickly branched, narrow leafed, and sometimes thorned. The physiognomy of caatinga is variable. In some areas it may resemble shrubland steppe, and in
other regions may be a dense scrubland with canopies reaching ten meters.
Cactus may also be found.
- ...pantanal
- Pantanal - A phytogeographical complex covering over 100,000 km
along
the Rio Paraguay and its tributaries in Brazil, Bolivia, and Paraguay. The
Pantanal region is primarily a humid savanna of hygrophytic grassland of which
80%is flooded during the rainy season (Oct.-March). In areas of higher local
relative relief, pantanal includes shrubs, woodland, and riparian forests
along the banks of the rivercourses.
- ...(N)
- Campos cerrados (N) -
Medium-tall grassland with several species of broad-leaved evergreen trees and
shrubs. These trees and shrubs average 5 meters in height, have thick bark,
twisted branches, and partially deciduous leaves which may be hairy and
leathery. Anthropogenic change, edaphic factors, and fire in the campos
cerrados (N) make the landscape extremely variable.
- ...(S)
- Campos cerrados (S) -
Medium-tall grassland with several species of broad-leaved evergreen trees and
shrubs. This formation is located in Southern Brazil and north-central
Paraguay. It is distinguished from campos cerrados (N) by its shorter dry
season and a definite cool season. In general, it possesses a denser understory
than the northern campos cerrados. Primarily grassland with sedges,
shorter palms are sometimes common.
- ...sujos
- Campos sujos - ``Dirty
Grassland''. A prairie grassland with scattered shrubs. Within the study area
of this paper, they are located along the upper Rio Branco in northern Brazil.
- ...limpos
- Campos limpos - Tall prairie grassland
nearly devoid of shrubs and trees. Within the study area, these areas are mixed
with campos sujos in northern Brazil.
