Production unit table

Description

Production unit table from the Atlantic salmon Dam Impact Analysis model v67. Division of Penobscot River watershed into sections, or Production Units (PUs). Gives boundaries, habitat units, production potential, and length of each PU.

Usage

production_units

Format

A dataframe with 15 observations of 12 variables

PU

Production unit number (Neiland et al. 2015)

Boundaries

Boundaries used to delimit PU

HU

Habitat units

HU_scen

Habitat units in default scenario

Proportion_of_HUS_in_scenario

Proportion of habitat units within PU (of entire watershed)

Adjusted_proportion_of_HUs_in_scenario

Adjusted cumulative proportion of habitat units within PU (of entire watershed)

Smolt_production_potential

Number of smolts that can be produced in each PU based on HUs

Longest_segment_length_km

Maximum segment length of PU (km)

Partial_segment_length_1

First partial segment length, if applicable

Partial_segment_length_2

Second partial segment length, if applicable

Hatchery_segment_length

Length of hatchery stocking segment

Dam

Name of dam at downstream end of PU
