Abstract

The State of Mato Grosso in Brazil has undergone intensive land use changes over the past decades. Native ecosystems have been converted into agrosystems for the production of cash crops and cattle. The Brazilian Forest Code advocates full protection of specifically sensitive habitats, and it also safeguards a fixed percentage of native vegetation known as “Legal Reserves” (LRs) inside private rural properties. As part of Brazilian Legal Amazonia region, in Mato Grosso, these percentages account for 35 % of savannas and 80 % of forests found inside each rural property. Here we analyze at the scale of the three biomes: Cerrado, Amazonia and Pantanal, the changes in native vegetation cover (NVC) from 1992 to 2007 and the representativeness of NVC types within the LRs, as well as the role of LRs for general landscape configuration and conservation. In Mato Grosso, 90 % of all studied NVC types are represented inside LR patches. Legal Reserves also accounted for 37 % of the total protected areas and for 37.8 % of all remnant NVCs found in Mato Grosso in 2007. The importance of LRs for landscape structure varied greatly according to biome, but it is noteworthy that LRs were generally missing in highly deforested zones. The relative small size of LRs in all biomes (55 to 64 % of them are ≤12 ha) makes them specifically vulnerable to further changes in land use. Considering the current tendency of ongoing fragmentation, the importance of LRs for landscape connectivity should be increased, specifically by improving the network of corridors between these remnant native vegetation areas.

Claims other papers make about this one

Each is checked against this paper’s own text: does it say what the citing paper says it does?

  • Deforestation has been very intensive in Southern Amazonia, followed by an increase of agro-combustive plantations and big and small hydropower dam projects, resulting in greater erosion and pollution, and fewer free-flowing river reaches with the capacity to absorb pollution.

    “Deforestation has been very intensive in Southern Amazonia [54], followed by an increase of agro-combustive plantations and big and small hydropower dam projects, resulting in both greater erosion and pollution, and fewer free-flowing river reaches with the capacity to absorb the pollution [66].”
  • Enforcement of existing laws, protection of riparian forests and headwater swamps, maintenance of environmental flows, public decision to keep parts of the river continuum entirely free of dams, and the principle of espace de liberté can solve large parts of the rural problem.

    “Very often, enforcement of existing laws (e.g., the Brazilian Forest Code, [54]), protection of riparian forests and headwater swamps [177], maintenance of environmental flows [87], and the public decision to keep parts of the river continuum entirely free of dams (e.g., [10]), and the principle of “espace de liberté” (space for river dynamics), can solve a large parts of the rural problem.”

About these checks

Registry, retraction, Cites and statistics results are computed, not judged, with one exception: a printed reference that no index lists is read once by a model before it counts as a citation error. Claims are extracted by a model and kept only when their quote appears verbatim in the text; each cited source is then checked, with a model’s help, for whether it says what the claim relies on. Those verdicts can be wrong — read the claim’s quote and the cited source before relying on one.

Statistics and arithmetic are recomputed, not judged.

Confidence bands are shown only for fields calibrated on our annotated test set. None is calibrated yet, so no band is shown.
