The phrase "a decrease in above ground" is correct and usable in written English.
It can be used in contexts discussing environmental changes, construction, or any situation where the level or amount of something above ground is being measured or analyzed.
Example: "The study reported a decrease in above ground vegetation due to the recent drought."
Alternatives: "a reduction in above ground" or "a decline in above ground".
In contrast, forest degradation is a more poorly understood process which involves partial canopy loss with no clear reduction in forest area, but a reduction in ecosystem services, more often described by a decrease in above ground biomass [15 19], and is the definition applied in this study.
There was a decrease in above ground plant biomass of 45% as irrigation frequency decreased but the treatment effect was not significant at P = 0.419 (Table 1).
A sigmoidal logistical model successfully described the decrease in above-ground mass with depth for P. tenax, whereas below-ground biomass decreased linearly with depth; the overall depth response for total biomass was also logistic.
Isolation bearings have been a widely applied seismic strengthening technique in above ground structures.
The spacious backyard has a decked-in above-ground pool and a whirlpool bath.
There was a significant variation in above-ground dry matter accumulation and harvest index (HI) in rice genotypes (Table 2).
(2) In D1 and D2 water treatments, there was a decrease in total biomass, above- and below-ground growth and biomass of both species in SS, and as water was reduced, the difference in plant height and leaf area between SS and SCK decreased in both species, and the difference in root length and root surface area between SS and SCK increased.
GEP and ecosystem respiration were increased by nutrient additions and decreased by grazers, reflecting similar changes in above-ground primary producer abundance (Figs. 5, 7).
Build a small house above ground in a Mushroom biome.
In contrast, the high N rate application decreased nodulation, but an increase of above ground biomass production was observed [21].
The mechanization of above-ground mountaintop removal has prevented any diversified economy and led to a decrease in coal mining jobs in some of the highest poverty stricken strip-mining areas.
