Project Objectives (from R & D Agreement)
- Determine the effects of timing, duration, and depth of flooding on the growth of a range of wetland plants with differing reproductive and growth strategies.
- Investigate the effect of grazing and the interaction of grazing with water regime on production of reproductive units by aquatic plants.
- Determine the effects of water regime on the allocation of plant biomass to different reproductive modes.
- Validation of selected response patterns by studying wetland plants in temporary wetlands under a range of natural flooding and drying regimes.
- Model the responses of the different reproductive types under different water and grazing regimes from an 18-30 month data set.
- Present findings in a way that can be used by water managers to aid in the planning of flooding and drying regimes in temporary wetlands.
