Most acquisitions are intended to increase habitat at existing wetland complexes, so it is unlikely that tracts will be acquired in the entire 35-county area. Most WPAs are small, from 100 to 500 acres (2.0 km 2), but several have grown considerably. Union Hills WPA in Cerro Gordo County is the largest in Iowa at over 2,000 acres (8.1 km 2).
There is a dearth of natural areas in Iowa; less than 1% of the tallgrass prairie that once covered most of Iowa remain intact, only about 5% of the state's prairie pothole wetlands remain, and most of the original forest has been lost. [6] Iowa ranks 49th of U.S. states in public land holdings. [7]
These included 28,100,000 acres (114,000 km 2) of updated wetland map information, new data for 6,800,000 acres (28,000 km 2) not previously available and 31,300,000 acres (127,000 km 2) of data that were captured in digital format. An additional 8,245 hard copy maps (quadrangles) were added as raster image files.
Barringer Slough (red) on landform map of Iowa. Barringer Slough is a rich wetland area located in northeast Clay County in northwestern Iowa. This area is a reconstructed remnant of the Des Moines lobe, a region of Iowa which was once covered by interconnected prairie wetlands. This wetland marsh and the surrounding public uplands cover 1,526 ...
Western US – One of the best spring forage sources for honeybees. Blooms 45–60 days and continuously produces nectar throughout the day. Can be seeded several times per year. Prefers 3 ft of topsoil. 180–1,500 pounds honey per acre, depending on soil quality and depth; 300–1000 pounds of pollen. [9] G, H Plantain: Plantago Major ...
In drier wetlands of the PPR, the vegetation varies from spikerush, which is found in the wetter areas of the wetland, to foxtail barley and wheatgrass on the outer edges of the wetland. [7] The variable availability of water in the Prairie Pothole Region is buffered by an abundant seed bank under the soil, comprising species that thrive under ...
The average price of Iowa farmland reached $11,835 an acre last year, an ISU survey shows, the second year in a row that values set a record high. They have climbed 63% compared to five years ago ...
The NWI relies on trained image analysts to identify and classify wetlands and deepwater habitats from aerial imagery. NWI started mapping wetlands at a small scale (1:250,000 map which covers an area the size of 128-1:24,000 USGS topographic maps or approximately 7,400 square miles).
