treetopper

Python module for calculating Stand data using tree species of the west coast.

DOCUMENTATION https://zacharybeebe.github.io/treetopper/

Installation

pip install treetopper

Blank Inventory Sheet

If you would like to download a blank, formatted inventory sheet in .csv or .xlsx...

python -m treetopper.blank_sheet

Example Workflows

To go through example workflows with treetopper, this can be done in with the stand module.

There are 6 different workflows that show examples of how treetopper works, these workflows will show console reports, create csv/xlsx files of stand plot data, create pdf reports, and/or create FVS-formatted databases

The workflow number (1 through 6) is the only argument when calling the stand module.

python -m treetopper.stand [workflow_number]

The summary of the workflow and the outputs will print at the bottom of the terminal

Species Available to be cruised

The species available for calculation are below and must have the correct species code...

'DF': 'DOUGLAS-FIR'
'WH': 'WESTERN HEMLOCK'
'RC': 'WESTERN REDCEDAR'
'SS': 'SITKA SPRUCE'
'ES': 'ENGLEMANN SPRUCE'
'SF': 'SILVER FIR'
'GF': 'GRAND FIR'
'NF': 'NOBLE FIR'
'WL': 'WESTERN LARCH'
'WP': 'WHITE PINE'
'PP': 'PONDEROSA PINE'
'LP': 'LODGEPOLE PINE'
'JP': 'JEFFERY PINE'
'SP': 'SUGAR PINE'
'WF': 'WHITE FIR'
'RF': 'RED FIR'
'RW': 'COASTAL REDWOOD'
'IC': 'INSENCE CEDAR'
'RA': 'RED ALDER'
'BM': 'BIGLEAF MAPLE'
'CW': 'BLACK COTTONWOOD'
'AS': 'QUAKING ASPEN'

Getting Started

An example of how to get started is...

from treetopper import *

"""
This workflow will create a quick cruise stand from manually entered plot/tree data
and then will display a console report, create a pdf report and create a csv file
of the stand's plot data in the current working directory.

Using the ThinTPA class, we will run a thinning scenario on the stand to a target density
of 80 Trees per Acre considering all species and diameter ranges. Then it will display a
console report of the thinning and create a pdf report.

Finally we will use the FVS class to create a SQLite database that is formatted for use
in FVS. FVS is the US Forest Service's "Forest Vegetation Simulator" software.
