Metadata for 'adult_tree_growth_survival.csv'  
  
Live tree growth data measured following standardized methods (Hurst and Allen 2007) and extracted from the NVS 
database (https://nvs.landcareresearch.co.nz/Home/Index). The data comprises a number of projects/surveys and 
was used to parameterize tree growth for Marine terraces (Kunstler et al. 2009 Journal of Ecology 97:685-695).
  

Column header abbreviations and data codes are as follows:

'project_plot_year': identifying code for the project, plot and year.

'project': survey area where the plot is located.

'plot': plot identifier.

'tree_tag': tree identifier.

'species': species code; described in Table A1 of of Appendix B (Fortsyth et al. 2015).  

'transect': name of the transect. 

'dbh1_mm': diameter at breast height (in mm) for year 1.

'dbh2_mm': diameter at breast height (in mm) for year 2.

'year_1': year of first measurment. 

'year_2': year of second measurment. 

'altitude': altitude of the plot (in m asl).

'plot_area': area of the plot (in m^2).
