get_annual_gross_yield {growR} | R Documentation |
Based on data from Table 1a in Lookup Table of expected yield as functions of height and management intensity after Olivier Huguenin et al. (2017).
get_annual_gross_yield(elevation, intensity = "high")
elevation |
The elevation of the considered site in meters above sea level. |
intensity |
One of ("high", "middle", "low", "extensive"). Management intensity for considered site. |
