Demography of the giant monocarpic herb Rheum nobile in the Himalayas and the effect of disturbances by grazing.

ABSTRACT:

Background

Perennity of giant rosette species in combination with a single 'big bang' reproduction followed by death of the genetic individual is relatively rare among plants. Such long-lived monocarpic plants are usually slow growing and can be found in deserts, bogs or in alpine regions of the tropics or sub-tropics. Due to their longevity, monocarpic perennials risk losing everything before reproduction, which make them particularly susceptible to disturbances. Because of the inherent difficulties in assessing whether long-lived populations are growing or declining, usually neither their demography nor the consequences of increasing grazing pressure are known.

Methods

We used integral projection modelling (IPM) to measure the growth rate and passage time to flowering of R
