Calculations indicate that a potential seed loss per cross of about 10% could be expected by roguing a 15-clone orchard to 5 clones, provided certain assumptions are met. Simultaneously, the theoretical percentage of selfed seed rose from 1 to 3% with the same roguing intensity. Roguing to fewer than five clones resulted in greater losses in potential seed yield.

A census of this species was performed in 2010 in UP at potential ISC habitats such as ponds, rivers, canals, agricultural fields and others. Data were collected regarding habitat types, threats, ownership, and other characteristics. In addition to the in-field census, subjective, qualitative data were obtained through a questionnaire survey. The total population of ISC was observed to be 11,905 and the population demonstrated a recruitment rate of 13%. No evidence supporting a declining population status was found. Some Agro-climatic Zones indicated a high population of cranes. For example, the Central Plain and the South Western Semi-Arid Plain had over 4,300 individuals each. Conversely, a very low population was observed in the Tarai Agro-climatic Zone, and no cranes were observed in Vindhyan Zone. ISC appear to form social organization ...
