“…Previous riparian groundwater use estimates for the basin have assumed all riparian vegetation of the same type (e.g., grassland, woodland, forest) within the watershed were functionally equivalent to the measurements from representative sites. Unfortunately, riparian areas are highly disturbed and comprised of patchy groupings with different vegetation ensembles (Campbell and Green, 1968) that have varying environmental drivers-all of which affects the magnitude of vegetation ET (Gazal et al, 2006). Our approach essentially accounted for variability in vegetation amount and vigor for every 250 m riparian pixel.…”

“…In some cases, as on the San Pedro, the process of pioneer forest expansion and succession to competitive species can occur over centuries (Johnson, 1994). There are, however, some rivers in which the physio-climatic settings produce frequent intense floods, thereby perpetually maintaining the riparian forests in an early successional stage (Campbell and Green, 1968). …”

Natural and human disturbances have had fundamentally different effects on ecosystems. Range scientists have proposed a new successional model, a “state‐and‐transition model,”which recognizes the possibility of multiple stable states in vegetation. This paper assesses this model via an investigation of the influence of fluvial processes and landforms on variation in a mosaic of riparian vegetation patches of different ages on a river reach in montane southwestern Colorado. We sampled the composition of herbaceous and shrubby plants in 67 contiguous patches along a 6 km reach of the river, measured 14 environmental variables in each patch, and then analyzed the relationship of the vegetation and environmental gradients using correspondence analysis. The variation in vegetation correlates most higly with the age of the patch, surficial‐sediment size, and soil development, which represent different aspects of a gradient in time since last disturbance by floods. A consistent pattern of post‐flood succession is not evident in the trends in species richness, mean percent cover, and species composition. The evidence suggests that exceptional floods in 1911 and 1927 altered fundamentally the physical environment on newly exposed bars. As a result, succession slowed and its trajectory may have been redirected toward a new stable state. While this may be a case of multiple stable states in a natural ecosystem, we suggest that such cases are rare in natural ecosystems. We also argue that proponents of state‐and‐transition models conclude wrongly that these models imply that managers can, or should, choose the desired state based primarily on human uses instead of managing for the potential natural vegetation. That decision is a societal one that should not be implicit in a successional model.
