Weinstein et al. 2013: “Restoration planners should and must view
restoration goals in the context of the full estuarine mosaic”
12. OBJECTIVES
1) Model change in the restoring habitat mosaic through time
2) Determine prey availability in each habitat type
3) Figure out which prey taxa are being consumed by juvenile
Chinook salmon and in what quantity
4) Use a bioenergetics model to estimate the “quality” of
estuarine habitat as the mosaic shifts

Notas del editor
Encroachment of mudflat into low marsh estuarine habitat/restoration area may encourage expansion of low energy prey
BUT if productivity is increased there may also be more of it.
