Huron Shores
This RNA contains the only representation of a high-quality pine-oak forest type within a dry ice-contact hill landtype. This site is comprised of a high-quality pine-oak ecosystem (150 acres), 130 acres of early successional forest species resulting from tornado impacts, and 110 acres of intensively managed aspen stands.

Ecological Information

Physical and Climatic Conditions

Nearest weather station, with distance and direction from RNA:
The nearest weather station is located at Loud Dam in Iosco County, 10 miles (16 km) south of the RNA.
Annual precipitation (type, seasonal distribution) :
Average annual rainfall is 28 inches (71 cm), and average annual snowfall is 51 inches (129 cm).
Maximum and minimum temperatures:
The average daily maximum temperature is 37.8 ºF and the average daily minimum is 0.6 ºF. The annual mean temperature is 19.2 ºF.
The elevation varies from 930 to 1060 feet (283-323 m).
Geology and Soils:
The RNA is comprised of rolling ridges of end moraines and glaciated topography connecting a high plateau of sandy outwash plains (to the west and south) with lower elevation ground moraines (to the east and north). Landforms and soils within the RNA are characteristic of ice-contact topography. The following soil types are found within the RNA: Sandy Mixed Frigid Entic Haplorthod and Mixed Frigid Alfic Haplorthod.
Aquatic Features:
Martineau Creek and an unnamed stream flow through the south unit. The Carp River lies adjacent to the southern boundary of the north unit. An unnamed intermittent stream flows through the central area of the north unit. A high water table is a prominent feature, and ponds and standing water are common.
