From the earliest days of settlement in Western Australia, native species of J- plants have been responsible for stock losses. As early as 1837, the plant now known as York Road Poison, was apparently causing the death of cattle, sheep and goats in the Guildford area, although the cause of the losses was at that time unknown. By 1842, James Drummond, the earliest of the botanical workers in Western Australia, had identified at least three species of Gastrolobium and one species of Oxylobium as being toxic. Subsequent experience in the field, together with experimental evidence has proved that 25 species of Gastrolobium and six species of Oxylobium are toxic to stock.
