El conocimiento de las flores de los condados de Texas es fundamental para determinar la composición, el manejo, la preservación y la restauración de las especies en todo el estado. Como la mayoría de los condados de Texas, los datos florísticos del condado de Erath, Texas, son poco conocidos. Los objetivos de esta investigación fueron compilar una flora para el condado de Erath, determinar las especies introducidas, endémicas, amenazadas y en peligro de extinción, así como hacer comparaciones con la flora original del condado y la de la región centro norte de Texas. El trabajo de campo se llevó a cabo desde septiembre de 2003 hasta diciembre de 2009 en 35 sitios en el condado de Erath. Además, se registraron herbarios para localizar especímenes del condado de Erath. Se identificaron un total de 870 especies (888 taxones) en 103 familias. Se introdujeron 144 taxones, mientras que 744 taxones eran nativos. Dieciocho de las especies son endémicas de Texas. Había dos plantas raras, Dalea reverchonii y Penstemon guadalupensis, pero no se encontraron plantas amenazadas o en peligro durante la investigación. Durante la investigación se recolectaron cuatro especies nocivas incluidas en la lista estatal: Arundo donax (junco gigante), Convolvulus arvensis (enredadera de campo), Tamarix chinensis y T. gallica (cedros de la sal).
