We installed 19 groundwater wells at upland locations selected to provide similar soil type, landscape position and slope.
Furthermore, when different number of upland locations were randomly selected to estimate ¯θg, the estimation accuracy was only improved slightly when more than 10 locations were used.
Our results demonstrated that spatial means and variability of soil moisture could be reliably estimated using measurements from nearby uplands provided previous soil moisture datasets for gullies and upland locations are simultaneously available.
The upland locations that were within a ±5% relative bias error for the estimation of ¯θg had similar average percentage clay content (16.1%) in the surface layer (0 20 cm) to that in the gullies (15.7%), and moderately steeper slopes (from 36.6%too 53.1%) compared to the upland average (39.4%).
We conducted scan samples in 58 upland locations.
Human settlers disseminated the domestic types even more widely to otherwise inaccessible coastal sites not reached by floating and particularly to inland and upland locations on large islands and continental land masses.
For example, young trees of Nyssa sylvatica (blackgum) raised from seeds of trees growing in swampy, low-lying locations in the eastern United States had a higher frequency of grafting (11%) than did trees originating from seeds of blackgum growing in well drained, upland locations (2%) of the same geographical area.
In recent years, species richness was lowest at midpoint locations, and increased at upland edge locations.
Most areas in the UK susceptible to sink-holes are relatively small or are in upland rural locations, with the Peak District having a relatively small population of 37,905.
In this study, we compared soil organic C (SOC) stocks and fractions under traditional hay meadow and conventional (silage or permanent) pasture management regimes at two upland grassland locations within the Yorkshire Dales, northern England, United Kingdom.
