d_species

Table containing the information about species level data. Each row corresponds to one species/cohort.

datasets

Provides a flexible and easy-to-use interface for the Physiological Processes Predicting Growth (3-PG) model written in Fortran. The r3PG serves as a flexible and easy-to-use interface for the 3-PGpjs (monospecific, evenaged and evergreen forests) described in Landsberg & Waring (1997) <doi:10.1016/S0378-1127(97)00026-1> and the 3-PGmix (deciduous, uneven-aged or mixed-species forests) described in Forrester & Tang (2016) <doi:10.1016/j.ecolmodel.2015.07.010>.

d_species function

A <code>data frame</code> with number of rows corresponding to each species/cohort and 8 variables:<dl>
 <dt>species</dt>
<dd>species or cohort id/name. It must be consistent with species names in <code>d_thinning</code>, <code>d_parameters</code> and <code>d_sizeDist</code> tables.</dd> <dt>planted</dt>
<dd>year and month indicating when the species was planted. Provided in form of year-month. E.g. "2000-01"</dd> <dt>fertility</dt>
<dd>soil fertility for a given species. Range from 0 to 1</dd> <dt>stems_n</dt>
<dd>number of trees per ha</dd> <dt>biom_stem</dt>
<dd>stem biomass for a given species (Mg/ha)</dd> <dt>biom_root</dt>
<dd>root biomass for a given species (Mg/ha)</dd> <dt>biom_foliage</dt>
<dd>initial foliage biomass (Mg/ha). If this is a leafless period, provide the spring foliage biomass.</dd>
