Summary

Waterbirds breeding at wetlands in North Dakota forage mostly on aquatic invertebrates. Historically, productivity and abundance of aquatic invertebrates primarily was driven by inter-annual hydrological dynamics (i.e., wet-dry cycles). Wetland drying allows for nutrient cycling and a subsequent pulse of productivity when wet conditions return. However, abundance and quality of wetlands in North Dakota has declined due to landscape modifications, primarily agriculture. Consolidation drainage, a practice of draining less permanent wetlands into larger more permanent ones, is common in North Dakota and it increases connectivity and stabilizes water levels among remaining wetlands. For the effective management and restoration of wetland [...]

Purpose

Study Objectives: 1) Examine changes in wetland depth and surface water area in relation to climate, upland disturbance, and wetland connectivity; 2) Examine changes in amphipod densities in relation to water-level change and landscape modification; 3) Examine the abundance and distribution of fish in prairie wetlands in relation to water-level change and wetland connectivity; 4) Examine the abundance and distribution of cattail in prairie wetlands in relation to water-level change and upland disturbances.
