Understanding the geology, stratigraphy and hydrology is critical to managing our water resources. We only have County Geologic Atlas on 1/3 of our counties; we need more. Understanding the recharge rates, contamination risk and depletion are the foundation of water management and we need good maps.
In order to farm, harvest forests, fish, rebuild roads, or even manage our backyards, one needs to know where invasive species are growing in order to find and eradicated. This requires a repetitive, statewide mapping and remote sensing approach. Currently there are a few scattered programs at local, state and federal programs but nothing comprehensive which can tell the landowner easily where a new infestation may ...more »
Wetlands are the filters or kidneys of our lakes, rivers and groundwater. Restoring wetlands will functionally clean water more than most buffers..especially drained ag wetlands. Interpretation and mapping of historical aerial photos going back to the 1920's will help identify the degraded or destroyed wetlands and former lakes. The DNR should lead an effort to dig into this archive of imagery to find potential restoration ...more »
Minnesota continues to be a leader in mapping and monitoring our wetlands. The state was one of the first to be mapped by the NWI program in the 1970s and is now being updated through substantial support by the LCCMR to the MN DNR. The mapping update will be completed around 2018. The state is about 1/2 complete. This was done with the University of Minnesota , Remote Sensing and Geospatial Analysis Lab, Ducks Unlimited, ...more »
