The phrase "a decrease in cover" is correct and usable in written English.
It can be used in contexts discussing reductions in protective layers, coverage, or availability of something.
Example: "The recent environmental changes have led to a decrease in cover for many species in the region."
Alternatives: "a reduction in cover" or "a decline in cover".
All ecoregions with forest cover had a decrease in forest cover.
Positive RdNBR values represent a decrease in vegetation cover and a higher burn severity, while negative values would represent an increase in live vegetation cover following the fire event.
Secondly, despite their peripheries experiencing a decrease in vegetation cover, a more detailed analysis found differences on the northern and eastern peripheries where increases of vegetation cover were observed, and other new peripheries where vegetation loss was massive.
Permafrost degradation will be accompanied by progressive drying of the surface (surface soil materials become coarse and gravelly) and a decrease in vegetation cover and biomass in grasslands of the central QTP5,15.
Our results show a decrease in tree cover in the 1970s followed by an increase since the mid-1980s, a pattern correlating with the temporal trends in rainfall as well as remotely sensed greening in the region.
From the C-band radar satellite data series, measured relative backscatter trends hint toward a decrease in snow cover through time and a more frequent presence of ice layers from mid-winter rain on snow events at Kapp Linné, Svalbard.
Thus, the hypothesis that summer and spring burning results in a decrease in canopy cover by woody vegetation is rejected.
End of century probabilities of a decrease in coral cover of 50% (relative to 2000 levels) are significantly less likely than the 99% decrease of the "less resilient" case.
Degraded forests are characterised by a decrease in canopy cover and density after selective exploitation of valuable tree species.
