Project Objectives (from R & D Agreement)

  1. 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.
  2. Investigate the effect of grazing and the interaction of grazing with water regime on production of reproductive units by aquatic plants.
  3. Determine the effects of water regime on the allocation of plant biomass to different reproductive modes.
  4. Validation of selected response patterns by studying wetland plants in temporary wetlands under a range of natural flooding and drying regimes.
  5. Model the responses of the different reproductive types under different water and grazing regimes from an 18-30 month data set.
  6. 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.
