LOCAL INFORMATION<br />

Environmental Description: This mapping unit includes dense, shrubby regeneration of<br />

hardwood species on areas that have been cleared in the recent past (less than 20 years).<br />

<strong>Vegetation</strong> Description: Deciduous sprouts from stumps <strong>and</strong> small trees form an impenetrable<br />

thicket 4-6 m tall, often intertwined with woody vines. Occasional mature trees may be scattered<br />
