Upper Chiquita Canyon Habitat Conservation Area Restoration and Management, Orange County, California – Transportation Corridor Agencies

conservation soil mapping soil analysis revegetation drainage wetlands riparian Restoration Ecology

Land IQ is responsible for managing a 1,158-acre conservation easement in southern Orange County that supports important populations of California gnatcatchers and coastal cactus wrens. Land IQ staff conducted evaluations to identify restoration opportunities on approximately 500 acres of land disturbed by historic dry-land farming and grazing, and developed efficient restoration techniques for large-acreage areas of coastal sage scrub, native grassland, oak woodland habitats and rare plant species. Specific evaluations included:

  • Mapped soils, existing native habitats and exotic species infestations;
  • Conducted soil analysis and detailed soil characterization to determine appropriate restoration and future management;
  • Evaluated ephemeral drainages using the hydrogeomorphic method to assess riparian functions of the non-wetland drainages;
  • Conducted research for native grass restoration.

Based on the evaluations, Land IQ developed a habitat restoration plan that includes rationale, methods and performance standards for the comprehensive restoration of the Conservation Area. This plan was incorporated into the Comprehensive Resource Management Plan (RMP) that Land IQ recently updated. The updated RMP provides a flexible, long-term management plan that will serve as a blueprint for how the easement will be managed for habitat restoration. An interactive, web-based restoration management tool using GIS was also developed to enable the client to better manage biological resources and the restoration activities in the Conservation Area.

Management of this easement will be an ongoing project until the land becomes part of Orange County’s Southern Natural Communities Conservation Plan/Habitat Conservation Plan (NCCP/HCP) for the Southern Subregion.

Bureau of Indian Affairs Land Classification

land classification water rights salinity soil mapping Agriculture Water Resources

The Blackfeet Indian Reservation comprises approximately 1.5 million acres and is located in northwestern Montana on the east side of the Continental Divide. The dominant land use is grazing, followed by about 400,000 acres of dryland agriculture and 150,000 acres of upland game and timber management areas. Approximately 100,000 acres of land is currently in use as irrigated agriculture. For over a decade, Land IQ staff participated in land classification efforts for the entire reservation.

This classification effort was focused on detailed assessments of arability and irrigability with broad reaching drainage investigations for the purpose of avoiding salinization of lands, existing and proposed wetland delineations, stock water pond determinations, historic irrigation evaluations, water demand estimates for both agricultural and urban uses, and continuous ownership updates among other land development and evaluation activities. This comprehensive work effort was conducted under the direction of the United States Bureau of Indian Affairs on behalf of the Blackfeet Nation.

The work was completed to prepare for litigation or negotiation of the proposed overall water rights claim and resulted in significant documentation. Also, multiple mapping products were developed and updated over the decade-long activities. Work completed on the reservation contributed to establishing a final water rights claim that was presented to the State of Montana, Blackfeet Nation and the United States Department of the Interior. Efforts involved overall task management for approximately $1.8 million in labor, subconsultants, and expenses.
