Peak Height Velocity (PHV) Calculator

PHV Calculator

Estimate biological maturity using the Mirwald et al. (2002) maturity offset method. Calculates the time, in years, from Peak Height Velocity (the period of fastest growth).

Interpretation

Pre-PHV: Offset < -1.0 year
Circa-PHV: Offset between -1.0 and +1.0
Post-PHV: Offset > +1.0 year
