Mosquito soil series

Depth class: very shallow to moderately deep over permafrost

Drainage class: very poorly drained

Parent material: silty alluvium or organic matter over alluvium in regions of groundwater discharge

Landform: alluvial plains in broad valleys and flats

Slope: 0 to 3 percent

Mean annual temperature: 21 to 28 degrees F.

Mean annual precipitation: 9 to 14 inches

 

TAXONOMIC CLASS: Coarse-loamy, mixed, superactive, subgelic Ruptic Histoturbels

 

USE AND VEGETATION: Mosquito soils are used for wildlife habitat and watershed protection. Soil drainage is not improved sufficiently by clearing to allow agricultural use. The soils support forest of tamarack and black spruce, with shrub birch and cottonsedge in the understory.

 

DISTRIBUTION AND EXTENT: MLRA 229, Interior Alaska Lowlands. The series is of moderate extent. Groundwater discharge neutralizes organic acids in the organic horizon, and results in a higher pH of these horizons than in most other Ruptic Histoturbels in this region. Because permafrost is relatively impermeable, groundwater must be discharged through associated unfrozen soils.
