ECOPHYSIOLOGY OF RIPARIAN COTTONWOODS
<br />Continuing studies throughout the late 1990s and into the new
<br />century have extended this research and attempted to integrate
<br />physiological studies with water management case studies.
<br />Commencing in the late 1990s, studies have reported success-
<br />ful applications of deliberate river regulation to satisfy the eco-
<br />physiological needs of cottonwoods and thus effect the
<br />restoration of riparian cottonwoods. There have been consid-
<br />erable advances in the understanding of cottonwood ecophysi-
<br />ology and the continuing increase in this knowledge base
<br />should improve future prospects for cottonwood conservation
<br />and restoration.
