Wauke (Broussonetia papyrifera), or paper mulberry, was brought to Hawaiʻi by Polynesian voyagers. Its bast fiber produces the finest, most durable kapa in the Pacific. Wauke thrives in mesic valleys and near stream banks — rich soil, high moisture, wind protection. Because Hawaiian wauke is largely seedless, it propagates vegetatively through root suckers rather than seeds.

Wauke requires a growing cycle of 1–2 years before harvest. Each stalk is stripped of its outer bark, the inner bast soaked and fermented, then beaten into sheets of kapa. The connection between the plant and the textile is direct — the quality of the kapa reflects the care of cultivation.

Bamboo is the primary material for ʻohe kapala — the carved stamp tools used to apply geometric patterns to finished kapa. Practitioners carve intricate designs into bamboo nodes, then press them onto dyed kapa surfaces. Non-invasive clumping bamboo varieties are preferred by cultural practitioners. Bamboo sites are mapped here alongside wauke to support kapa practitioners sourcing both materials.

Traditional kapa was replaced by imported fabrics after Western contact. By the early 20th century, the knowledge had nearly vanished. The Hawaiian Renaissance of the 1960s–70s revived the practice. Today, practitioners at studios like Pūkoʻa Studios maintain seven active wauke patches across Oʻahu, continuing to grow, harvest, and beat kapa for hula, ceremony, and art.

Expanding wauke cultivation addresses a deeper ecological question: can we restore relationship to the land through the revival of material culture? Wauke cultivation in valleys and near waterways supports soil health, provides canopy structure, and reintroduces a keystone canoe plant to degraded landscapes. This map argues that the conditions for restoration exist — and locates them precisely.
