River Birch Farms

River Birch Farms is an alpaca breeder in Winlock, WA, Lewis County and the Pacific Northwest near Tacoma. They have over ten years of experience, participate in national alpaca registries, and follow industry standard health screening for each animal.

Their herd enjoys daily handling, pasture rotation, and year-round shelter to promote gentle temperaments. The farm began as a small homestead and has grown into a close-knit operation guided by family values.

Their alpaca fiber finds its way to local artisans who value its balance of warmth and durability. They select breeding pairs based on temperament, fleece quality and structural soundness to ensure a healthy, even-tempered herd. All crias receive early socialization, routine hoof trimming, deworming and vaccinations as part of their foundational care. The farm’s rolling pastures provide a tranquil backdrop and reflect careful sustainable land management, with on-site fleece grading.
