UCSB SONGS Mitigation Monitoring: Reef Performance Standard - Fish Abundance and Richness

These data describe annual estimates of the density and species richness (evaluated as species density) of young-of-year (less than 1 year old) and resident (greater than 1 year old) reef fish from replicate transects at three subtidal reefs.
Data collection began in 2009 at an artificial reef (Wheeler North Reef in Orange County, CA) and two natural reference reefs (San Mateo Kelp in Orange County, CA and Barn Kelp in San Diego County, CA) to evaluate the ability of Wheeler North Reef to compensate for losses of kelp forest habitat and associated biota caused by the operation of San Onofre Nuclear Generating Station (SONGS).

本数据集描述了基于三处潮下礁的重复样带调查所得的当年幼鱼（young-of-year，龄期不足1年）与定居礁栖鱼类（resident，龄期满1年以上）的密度及物种丰富度（以物种密度作为衡量指标）的年度估算结果。数据采集工作于2009年启动，调查位点涵盖一处人工礁——加利福尼亚州奥兰治县惠勒北礁（Wheeler North Reef），以及两处自然参照礁：加利福尼亚州奥兰治县圣马特奥海藻林（San Mateo Kelp）与加利福尼亚州圣地亚哥县巴恩海藻林（Barn Kelp）。本数据集旨在评估惠勒北礁能否弥补圣奥诺弗雷核电站（San Onofre Nuclear Generating Station，SONGS）运营所造成的海藻林栖息地及相关生物群落损失。
