Pacific foxtail

Pacific foxtail (lat. Alopecurus saccatus) is a perennial grass species belonging to the Poaceae family. This plant is well-regarded for its adaptability to wetland environments, making it a significant subject for study in forage production and land restoration projects within its native range.

The species is primarily native to Western North America, particularly the Pacific Northwest and California. Its natural habitat includes seasonally wet meadows, floodplains, and vernal pools. Due to its evolutionary history, the plant is highly specialized to survive in habitats that experience significant fluctuations in water availability, specifically tolerating seasonal flooding.

Botanically, Alopecurus saccatus is characterized by its tufted growth habit and distinct inflorescences. The spike-like panicles are cylindrical, with the individual florets enclosed in sac-like glumes, which serves as the diagnostic feature for this specific species. The foliage is generally linear and smooth, contributing to the nutritional quality of the plant when grazed by livestock.

Cultivation requirements for this grass focus on soil moisture management. It thrives in heavy, poorly drained soils where other common forage grasses might struggle. While it is not typically grown as a mono-crop in intensive agriculture, it is a valuable component of seed mixes intended for the restoration of wetland areas and permanent pastures that are subject to standing water.

In agricultural practice, the primary uses include pasture grazing and the maintenance of ecological integrity in wet meadow systems. The biomass is highly palatable in its early stages of growth. Producers should monitor for typical grass diseases such as rusts and powdery mildew, which are common in damp environments, as well as specific pests like grass flies that may occasionally impact biomass yields.
