Monitoring of plant phenology and seed production identifies two distinct seed collection seasons in the Australian arid zone

Phenological patterns including peak flowering and seed production of 19 grass, herb, shrub and tree species were studied in the Pilbara biogeographic region of Western Australia. Each plant population was monitored monthly over an 18-month period. Qualitative data was collected capturing plant phenophases. Plant fecundity was estimated using X-ray analyses to determine the proportion of seeds produced. Two main phenological patterns were...
