Indigenous people throughout North America were dramatically affected by the invasion of European colonizers. Growing evidence suggests that, among many strategies for survival and perseverance, increased sedentism was common; it often resulted from either forced resettlement or attempts to access European resources. We present artifactual, paleoethnobotanical, and faunal findings from the yak tichu tichu yak tilhini northern Chumash village of Tstyiwi (CA-SLO-51/H) where a reasonably discrete postcontact component provides evidence for extreme resource intensification and year-round site use following contact. Although there is evidence for diachronic settlement shifts preceding arrival of the Spanish, the postcontact occupation at Tstyiwi contrasts significantly with 35 exclusively pre-invasion components in its seasonal profile, artifact diversity, density of plant remains, and abundance of fishing equipment and fish bone. High frequencies of the latter two features seem to reflect use of a resource that became the primary focus of subsistence for this coastal community as its inhabitants intensified their work effort to levels never before seen in attempts to avoid the Spanish whose presence had restricted their foraging radius.

整个北美的土著人民受到欧洲殖民者入侵的巨大影响。越来越多的证据表明，在许多生存和坚持的策略中，久坐不动是很常见的。它通常是由于强制重新安置或试图获取欧洲资源造成的。我们展示了来自yak tichu tichu yak tilhini的人工、古民族植物学和动物学发现Tstyiwi 的北部 Chumash 村 (CA-SLO-51/H)，其中相当离散的接触后组件为接触后的极端资源集约化和全年场地使用提供了证据。尽管有证据表明在西班牙人到来之前定居点发生了历时变化，但在 Tstyiwi 的接触后占领与 35 个完全入侵前的组成部分在其季节性特征、人工制品多样性、植物遗存密度以及捕鱼设备和鱼骨的丰富性方面形成了鲜明的对比。后两个特征的高频率似乎反映了资源的使用成为这个沿海社区生存的主要焦点，因为其居民将他们的工作努力加强到前所未有的水平，以试图避开限制他们觅食半径的西班牙人.
