S4 Class Definition for NPSForveg

Description

An S4 class that contains the data from forest monitoring from a set of forest montoirng plots. This will typcially be a single park, but it could be any group of plots, including part of a park or a group of parks.

Slots

ParkCode

A short code to designate the park (or group of plots), typically an NPS 4 letter code. Stored as a length 1 character vector.

ShortName

A short name for the park. Stored as a length 1 character vector.

LongName

A long, formal name for the park. Stored as a length 1 character vector.

Network

The code for the I&M network the park belongs to. Stored as a length 1 character vector.

TPlotSize

A length 2 numeric vector. The first element is the number of subplots where trees are monitored at each plot. The second element is the size of each of the subplots in meters squared.

SapPlotSize

A length 2 numeric vector. The first element is the number of microplots where saplings are monitored at each plot. The second element is the size of each of the microplots in meters squared.

SeedPlotSize

A length 2 numeric vector. The first element is the number of quadrats where seedlings are monitored at each plot. The second element is the size of each of the quadrats in meters squared.

ShrubPlotSize

length 2 numeric vector. The first element is the number of microplots where shrbus are monitored at each plot. The second element is the size of each of the microplots in meters squared.

ShSeedPlotSize

A length 2 numeric vector. The first element is the number of quadrats where shrub seedlings are monitored at each plot. The second element is the size of each of the quadrats in meters squared.

VPlotSize

A length 2 numeric vector. The first element is the number of subplots where vines on trees are monitored at each plot. The second element is the size of each of the subplots in meters squared.

HPlotSize

A length 2 numeric vector. The first element is the number of quadrats where herbaceous plants are monitored at each plot. The second element is the size of each of the quadrats in meters squared. Note - these need not be actually herbaceous plants, but it is assumed that cover of each species is measured rather than the dbh or height.

Events

a data.frame with information on each sampling event

Trees

a data.frame with tree data

Saplings

Seedlings

a data.frame with seedling data

Shrubs

a data.frame with shrub data

ShSeedlings

a data.frame with shrub seedling data

Vines

a data.frame with vine data

Herbs

a data.frame with herbaceous plant data

CWD

a data.frame with coarse woody debris volume by species and decay class data

Commons
