County/City and Private ownership. UNIT J - Casserly - Private ownership. UNIT K - Elkhorn - Private ownership. In 2002, a total of 1,175 ha (2,902 acres) was designated as Critical Habitat. Efforts at active management to restore plant populations The Arana Gulch populations management, the City of Santa Cruz established their Adaptive Management Working Group (AMWG) which consisted of a group of stakeholders, whose composition was approved by the California Coastal Commission Executive Director. The members have been a researcher from UC Berkeley, a biologist from California Fish and Wildlife, a biologist from US Fish and Wildlife Service, an ecologist from the California Coastal Commission, three private consultants, a UC Cooperative Extension Livestock advisor, and Santa Cruz city staff from the Planning and Parks Departments. Semi-annual meetings were held from 2013 to 2016, with the last meeting March 14, 2016. Twin Lakes State Park (Unit D0 population management between 1998-2003 consisted of mowing in 1998, 1999, and 2001 once in spring, and once in fall using a string trimmer. The litter was then removed using garden rakes or McCleods. The site was scraped using McCleods. In 2002, mowing continued and 15 nursery raised plants planted on February 6. The nursery plants were more robust and produced over ten times the number of seed heads than the naturally occurring individuals. In 2002, 494 plants were grown from seeds harvested in previous years, and 344 of these plant survived, but were no more robust than the naturally occurring individuals. In 2002, where plants naturally occurred, was mowed twice as well as treated with a chain harrow. Population trends in individual plant populations Ecological restoration projects to restore individual populations of the plants, their annual reports usually contain plant counts or estimations of the numbers of plants with a population during a certain year, and that data can be used to measure trends and successes of the restoration techniques used. The Arana Gulch (Unit D) population first census in 1986 by Randy Morgan estimated that there were 100,000 plants on that site in Santa Cruz in four different "Areas", and by 2006 was extinct in three of the four areas, and in the remaining "Area A" had dropped to only 348 plants. Plants counts in 2013 only found 18 plants, in 2014 only 4 plants, and in 2015 zero, and 2016 34 plants. Zero plants at Arana Gulch grew in 2017, then
