STANDARD Exhibit: Survey and Inventory Data Collection Standards – Part B

EXAMPLE Invasive Plant Data Collection Data Fields & Lists of Values

This is an example of likely collection formats to collect data on invasive plant infestations. Depending on the individual task order, the Forest Service spatial contract data may be provided as an electronic datafile to be used with a portable data recorder or be made available to the contract via a data collection app. The Contractor can use a Field Maps (replacing Collector) form or a fillable form with the data found below or another method agreed upon by the COR and the Contractor. The COR will review this format with the Contractor during the Pre-Work conference.

At each invasive plant infestation to be mapped with GPS, collect spatial data per the requirements of Survey and Inventory Standards – Part A or as specified in the Task Order and enter the following data for each infestation.

Required Data Fields

Data Field: Date

Definition: Date the inventory took place

List of Values: Month/Date/Year

Explanatory Notes: None

Data Field: Examiner

Definition: Three Initials of Person Collecting the Data

List of Values:

Data Field: Ownership

Definition: Name of Landowner where GPS data is collected

List of Values:

• BLM

• County

• State

• FS

• Private (OR Name of Landowner, if Known)

Explanatory Notes: BLM=Bureau of Land Management. _C= e.g., Gem County- GC, Boise County, BC. IS=State of Idaho. FS=Forest Service. PL=Private Land. (If name of private landowner is known, please provide landowner’s name).

Data Field: Site Location Name

Definition: Specific geographic location followed by the NRCS Plants database alphanumeric code for the invasive plant species (e.g. LittleRoaring_EUES_024).

List of Values: Not Applicable

Explanatory Notes: The geographic location will be (a) a geographic or topographic place name,

(b) name of drainage in which infestation is located or (c) the name of the nearest feature with cardinal directions (N, NE, NW, E, S, SE, SW, W), indicating the location of the infestation relative to this nearest feature. The contractor will be provided maps with labeled geographic or topographic features.

Data Field: Invasive Plant Species

Definition: NRCS Plants database alphanumeric code.

List of Values: See Table at bottom of this Exhibit

Explanatory Notes: Only one plant species may be assigned to a particular GPS data feature. If more than one invasive plant species is present, separate GPS data features will be required for each plant species even if the populations/infestations are wholly overlapping.

Data Field: Plant Phenology

Definition: Predominant growth stage of invasive plant species at the time of inventory

List of Values:

• Rosette

• Bolt

• Flower

• Fruiting

• Senescent/Dormant

Explanatory Notes: Rosette = leaves arranged circularly, no distinguishable stem. Preflower = stem elongation, usually vertical, up to unopened bud stage. Flower = buds open, tepals present. Fruiting = plant has gone to seed and seed dispersal has begun. Senescent/Dormant = seed dispersal is complete, plant is dormant, dying, or plant appears to be dead.

Data Field: Cover Class Distribution

Definition: A subjective measure of invasive plant distribution (only in relation to area that is infested).

List of Values:

• I

• CL

• SE

• SP

• LI

Explanatory Notes: I = Isolated (e.g.,1 to 3 plants with no other populations/infestations nearby). CL = Grouped or clumped (e.g., plants are distributed in groups with no or few scattered plants between the groups). SE = Scattered Evenly (e.g., plants are evenly distributed within the population/infestation [Note: this category includes a dense monoculture of invasive plants]). SP = Scattered/Patchy (e.g., occasional or numerous patches of invasive plants with scattered plants between the groups). LI = Linear (typically and invasive species infestation distributed in a linear fashion, such as along a stream or road with few or no gaps in the distribution of the invasive plants).

Data Field: Percent Cover Class Code

Definition: Ocular estimated percent cover of invasive plant species in the infested area

List of Values:

• T – 0.1% - 1%

• 1 – 1.1% - 5%

• 2 – 5.1% - 25%

• 3 – 25.1% - 50%

• 4 – 50.1% - 75%

Explanatory Notes: An ocular estimate of the coverage of the invasive plant species within the area

Data Field: Distance to Water

Definition: Estimated horizontal and/or vertical distance from infestation to nearest water source for invasive plant control

List of Values: Not Applicable

Explanatory Notes: Please note presence and approximate distance to functioning stock tanks, upland spring, nearest stream, etc.

Data Field: Comments

Definition: Any remarks about the location or the population or infestation that will assist with plant management or invasive plant control treatments. Please include cheatgrass (Bromus tectorum), tumble mustards (Sisymbrium spp.), and other weedy annual species, etc. in this field.

List of Values: Not Applicable
