NATIONAL RANGE INVENTORY (NRI)

 

An extended agreement with NRCS also increasing funding, finds the District on its third year to provide assistance in the National Rangeland Inventory (NRI). This program is federally mandated throughout the nation.  The district provides assistance in the form of surveying and documenting designated points in southern California.  Each point is an onsite data collection for grazing and range inventory.  Each point is surveyed via 150 foot transects to collect environmental data including but not limited to plant life, land cover/use, landscape and soils, disturbance indicators and biomass/production, cover, density, and height.  Points are revisited every 5 years

 

The NRI program season is in the spring between the months of March and September, so no work was done in the fall of 2018.  So far this year Tony Walters, Team Leader, and Luis Cortes, Conservation Technician I, have attended a week-long training in Arizona to learn any new protocols for the coming year.

 

At this time there are twelve points in southern California scheduled for inventory, with more being assigned as they become available.  At each point, two transects are laid out and multiple vegetation and soil-based protocols are completed for each transect leg.  Protocols generally take between 2 and 4 hours onsite per point, and is complicated by the amount of vegetation, the irregularity of the terrain and often by prevailing temperatures. The data is entered onsite in a field computer or collected on field forms to be entered later.
